                             STOCK PURCHASE WARRANT


                  To Purchase 37,500 Shares of Common Stock of

                    WORLD WIDE WIRELESS COMMUNICATIONS, INC.

     THIS CERTIFIES that, for value received, The Keshet Fund, L.P. (the
"Holder"), is entitled, upon the terms and subject to the conditions hereinafter
set forth, at any time on or after March 29, 2001 (the "Initial Exercise Date")
and on or prior to the close of business on the third anniversary of the Initial
Exercise Date (the "Termination Date") but not thereafter, to subscribe for and
purchase from World Wide Wireless Communications, Inc., a Nevada corporation
(the "Company"), up to 37,500 shares (the "Warrant Shares") of Common Stock,
$0.001 par value per share, of the Company (the "Common Stock"). The purchase
price of one share of Common Stock (the "Exercise Price") under this Warrant
shall be $0.10. The Exercise Price and the number of Warrant Shares for which
the Warrant is exercisable shall be subject to adjustment as provided herein.
Capitalized terms used and not otherwise defined herein shall have the meanings
set forth in that certain Senior Secured Convertible Debentures and Warrants
Purchase Agreement (the "Purchase Agreement"), dated March 29, 2001, between the
Company and the investors thereto. In the event of any conflict between the
terms of this Warrant and the Purchase Agreement, the Purchase Agreement shall
control.








     1.  Title to Warrant. Prior to the Termination Date and subject to
compliance with applicable laws, this Warrant and all rights hereunder are
transferable, in whole or in part, at the office or agency of the Company by the
Holder in person or by duly authorized attorney, upon surrender of this Warrant
together with the Assignment Form annexed hereto properly endorsed.

     2.  Authorization of Shares. The Company covenants that all Warrant Shares
which may be issued upon the exercise of the purchase rights represented by this
Warrant will, upon exercise of the purchase rights represented by this Warrant,
be duly authorized, validly issued, fully paid and nonassessable and free from
all taxes, liens and charges in respect of the issue thereof (other than taxes
in respect of any transfer occurring contemporaneously with such issue).

     3.  Exercise of Warrant.

         (a)  Except as provided in Section 4 herein, exercise of the purchase
     rights represented by this Warrant may be made at any time or times on or
     after the Initial Exercise Date and on or before the close of business on
     the Termination Date by the surrender of this Warrant and the Notice of
     Exercise Form annexed hereto duly executed and delivered pursuant to the
     notice provision of the Purchase Agreement, at the office of the Company
     (or such other office or agency of the Company as it may designate by
     notice in writing to the registered Holder at the address of such Holder
     appearing on the books of the Company) and upon payment of the Exercise
     Price of the shares thereby purchased by wire transfer or cashier's check
     drawn on a United States bank, or by means of a cashless exercise, the
     Holder shall be entitled to receive a certificate for the number of Warrant
     Shares so purchased. Certificates for shares purchased hereunder shall be
     delivered to the Holder within three (3) Trading Days after the date on
     which this Warrant shall have been exercised as aforesaid. This Warrant
     shall be deemed to have been exercised and such certificate or certificates
     shall be deemed to have been issued, and the Holder or any other person so
     designated to be named therein shall be deemed to have become a Holder of
     record of such shares for all purposes, as of the date the Warrant has been
     exercised by payment to the Company of the Exercise Price and all taxes
     required to be paid by the Holder, if any, pursuant to Section 5 prior to
     the issuance of such shares, have been paid.

         (b)  If this Warrant shall have been exercised in part, the Company
     shall, at the time of delivery of the certificate or certificates
     representing Warrant Shares, deliver to Holder a new Warrant evidencing the
     rights of Holder to purchase the unpurchased Warrant Shares called for by
     this Warrant, which new Warrant shall in all other respects be identical
     with this Warrant.

         (c)  This Warrant shall also be exercisable by means of a "cashless
     exercise" in which the Holder shall be entitled to receive a certificate
     for the number of Warrant Shares equal to the quotient obtained by dividing
     [(A-B) (X)] by (A), where:



                                       2



              (A) = the average of the high and low trading prices per share of
              Common Stock on the Trading Day preceding the date of such
              election;

              (B) = the Exercise Price of this Warrant; and

              (X) = the number of Warrant Shares issuable upon exercise of this
              Warrant in accordance with the terms of this Warrant and the
              Notice of Exercise.

         (d)  Notwithstanding anything herein to the contrary, in no event shall
     the Holder be permitted to exercise this Warrant for Warrant Shares to the
     extent that (i) the number of shares of Common Stock owned by such Holder
     (other than Warrant Shares issuable upon exercise of this Warrant) plus
     (ii) the number of Warrant Shares issuable upon exercise of this Warrant,
     would be equal to or exceed 9.9% of the number of shares of Common Stock
     then issued and outstanding, including shares issuable upon exercise of
     this Warrant held by such Holder after application of this Section 3(d). As
     used herein, beneficial ownership shall be determined in accordance with
     Section 13(d) of the Exchange Act. To the extent that the limitation
     contained in this Section 3(d) applies, the determination of whether this
     Warrant is exercisable (in relation to other securities owned by the
     Holder) and of which a portion of this Warrant is exercisable shall be in
     the sole discretion of such Holder, and the submission of a Notice of
     Exercise shall be deemed to be such Holder's determination of whether this
     Warrant is exercisable (in relation to other securities owned by such
     Holder) and of which portion of this Warrant is exercisable, in each case
     subject to such aggregate percentage limitation, and the Company shall have
     no obligation to verify or confirm the accuracy of such determination.
     Nothing contained herein shall be deemed to restrict the right of a Holder
     to exercise this Warrant into Warrant Shares at such time as such exercise
     will not violate the provisions of this Section 3(d). The provisions of
     this Section 3(d) may be waived by the Holder upon, at the election of the
     Holder, with not less than 61 days' prior notice to the Company, and the
     provisions of this Section 3(d) shall continue to apply until such 61st day
     (or such later date, as determined by the Holder, as may be specified in
     such notice of waiver). No exercise of this Warrant in violation of this
     Section 3(d) but otherwise in accordance with this Warrant shall affect the
     status of the Warrant Shares as validly issued, fully-paid and
     nonassessable.

     4.  No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be entitled
to purchase upon such exercise, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to such fraction multiplied by
the Exercise Price.

     5.  Charges, Taxes and Expenses. Issuance of certificates for Warrant
Shares shall be made without charge to the Holder for any issue or transfer tax
or other incidental expense in respect of the issuance of such certificate, all
of which taxes and expenses shall be paid by the Company, and such certificates
shall be issued in the name of the Holder or in such name or names as may be
directed by the Holder subject to applicable law; provided, however, that in the
event certificates for Warrant Shares are to be issued in a name other than the
name of



                                       3



the Holder, this Warrant when surrendered for exercise shall be accompanied by
the Assignment Form attached hereto duly executed by the Holder; and the Company
may require, as a condition thereto, the payment of a sum sufficient to
reimburse it for any transfer tax incidental thereto.

     6.  Closing of Books. The Company will not close its stockholder books or
records in any manner which prevents the timely exercise of this Warrant.

     7.  Transfer, Division and Combination.

         (a)  Subject to compliance with any applicable securities laws,
     transfer of this Warrant and all rights hereunder, in whole or in part,
     shall be registered on the books of the Company to be maintained for such
     purpose, upon surrender of this Warrant at the principal office of the
     Company, together with a written assignment of this Warrant substantially
     in the form attached hereto duly executed by the Holder or its agent or
     attorney and funds sufficient to pay any transfer taxes payable upon the
     making of such transfer. Upon such surrender and, if required, such
     payment, the Company shall execute and deliver a new Warrant or Warrants in
     the name of the assignee or assignees and in the denomination or
     denominations specified in such instrument of assignment, and shall issue
     to the assignor a new Warrant evidencing the portion of this Warrant not so
     assigned, and this Warrant shall promptly be cancelled. A Warrant, if
     properly assigned, may be exercised by a new Holder for the purchase of
     Warrant Shares without having a new Warrant issued.

         (b)  This Warrant may be divided or combined with other Warrants upon
     presentation hereof at the aforesaid office of the Company, together with a
     written notice specifying the names and denominations in which new Warrants
     are to be issued, signed by the Holder or its agent or attorney. Subject to
     compliance with Section 7(a), as to any transfer which may be involved in
     such division or combination, the Company shall execute and deliver a new
     Warrant or Warrants in exchange for the Warrant or Warrants to be divided
     or combined in accordance with such notice.

         (c)  The Company shall prepare, issue and deliver at its own expense
     (other than transfer taxes) the new Warrant or Warrants under this Section
     7.

         (d)  The Company agrees to maintain, at its aforesaid office, books for
     the registration and the registration of transfer of the Warrants.

     8.  No Rights as Shareholder until Exercise. This Warrant does not entitle
the Holder to any voting rights or other rights as a shareholder of the Company
prior to the exercise hereof. Upon the surrender of this Warrant and the payment
of the aggregate Exercise Price or by means of a cashless exercise, the Warrant
Shares so purchased shall be and be deemed to be issued to such Holder as the
record owner of such shares as of the close of business on the later of the date
of such surrender or payment.

     9.  Loss, Theft, Destruction or Mutilation of Warrant. The Company
covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock
certificate relating to the Warrant Shares,



                                       4



and in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it (which shall not include the posting of any bond), and upon
surrender and cancellation of such Warrant or stock certificate, if mutilated,
the Company will make and deliver a new Warrant or stock certificate of like
tenor and dated as of such cancellation, in lieu of such Warrant or stock
certificate.

     10. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the
taking of any action or the expiration of any right required or granted herein
shall be a Saturday, Sunday or a legal holiday, then such action may be taken or
such right may be exercised on the next succeeding day not a Saturday, Sunday or
legal holiday.

     11. Adjustments of Exercise Price and Number of Warrant Shares. (a) Stock
Splits, etc. The number and kind of securities purchasable upon the exercise of
this Warrant and the Exercise Price shall be subject to adjustment from time to
time upon the happening of any of the following. In case the Company shall (i)
pay a dividend in shares of Common Stock or make a distribution in shares of
Common Stock to holders of its outstanding Common Stock, (ii) subdivide its
outstanding shares of Common Stock into a greater number of shares, (iii)
combine its outstanding shares of Common Stock into a smaller number of shares
of Common Stock, or (iv) issue any shares of its capital stock in a
reclassification of the Common Stock, then the number of Warrant Shares
purchasable upon exercise of this Warrant immediately prior thereto shall be
adjusted so that the Holder shall be entitled to receive the kind and number of
Warrant Shares or other securities of the Company which it would have owned or
have been entitled to receive had such Warrant been exercised in advance
thereof. Upon each such adjustment of the kind and number of Warrant Shares or
other securities of the Company which are purchasable hereunder, the Holder
shall thereafter be entitled to purchase the number of Warrant Shares or other
securities resulting from such adjustment at an Exercise Price per Warrant Share
or other security obtained by multiplying the Exercise Price in effect
immediately prior to such adjustment by the number of Warrant Shares purchasable
pursuant hereto immediately prior to such adjustment and dividing by the number
of Warrant Shares or other securities of the Company resulting from such
adjustment. An adjustment made pursuant to this paragraph shall become effective
immediately after the effective date of such event retroactive to the record
date, if any, for such event.

     12. Reorganization, Reclassification, Merger, Consolidation or Disposition
of Assets. In case the Company shall reorganize its capital, reclassify its
capital stock, consolidate or merge with or into another corporation (where the
Company is not the surviving corporation or where there is a change in or
distribution with respect to the Common Stock of the Company), or sell, transfer
or otherwise dispose of all or substantially all its property, assets or
business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, shares of common stock of the successor or acquiring corporation, or any
cash, shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Stock
of the Company, then the Holder shall have the right thereafter to receive, upon
exercise of this Warrant, the number of shares of Common Stock of the successor
or acquiring corporation or of the Company, if it is the surviving corporation,
and Other Property receivable upon or as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets by a Holder of
the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to such event. In case of any such reorganization,
reclassification, merger,



                                       5



consolidation or disposition of assets, the successor or acquiring corporation
(if other than the Company) shall expressly assume the due and punctual
observance and performance of each and every covenant and condition of this
Warrant to be performed and observed by the Company and all the obligations and
liabilities hereunder, subject to such modifications as may be deemed
appropriate (as determined in good faith by resolution of the Board of Directors
of the Company) in order to provide for adjustments of Warrant Shares for which
this Warrant is exercisable which shall be as nearly equivalent as practicable
to the adjustments provided for in this Section 12. For purposes of this Section
12, "common stock of the successor or acquiring corporation" shall include stock
of such corporation of any class which is not preferred as to dividends or
assets over any other class of stock of such corporation and which is not
subject to redemption and shall also include any evidences of indebtedness,
shares of stock or other securities which are convertible into or exchangeable
for any such stock, either immediately or upon the arrival of a specified date
or the happening of a specified event and any warrants or other rights to
subscribe for or purchase any such stock. The foregoing provisions of this
Section 12 shall similarly apply to successive reorganizations,
reclassifications, mergers, consolidations or disposition of assets.

     13. Voluntary Adjustment by the Company. The Company may at any time during
the term of this Warrant reduce the then current Exercise Price to any amount
and for any period of time deemed appropriate by the Board of Directors of the
Company.

     14. Notice of Adjustment. Whenever the number of Warrant Shares or number
or kind of securities or other property purchasable upon the exercise of this
Warrant or the Exercise Price is adjusted, as herein provided, the Company shall
promptly mail by registered or certified mail, return receipt requested, to the
Holder notice of such adjustment or adjustments setting forth the number of
Warrant Shares (and other securities or property) purchasable upon the exercise
of this Warrant and the Exercise Price of such Warrant Shares (and other
securities or property) after such adjustment, setting forth a brief statement
of the facts requiring such adjustment and setting forth the computation by
which such adjustment was made. Such notice, in the absence of manifest error,
shall be conclusive evidence of the correctness of such adjustment.

     15. Notice of Corporate Action. If at any time:

         (a)  the Company shall take a record of the holders of its Common Stock
     for the purpose of entitling them to receive a dividend or other
     distribution, or any right to subscribe for or purchase any evidences of
     its indebtedness, any shares of stock of any class or any other securities
     or property, or to receive any other right, or

         (b)  there shall be any capital reorganization of the Company, any
     reclassification or recapitalization of the capital stock of the Company or
     any consolidation or merger of the Company with, or any sale, transfer or
     other disposition of all or substantially all the property, assets or
     business of the Company to, another corporation where the Company is not
     the surviving corporation, or



                                       6



         (c)  there shall be a voluntary or involuntary dissolution, liquidation
     or winding up of the Company;

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 20 days' prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 20
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause also shall specify (i) the date
on which any such record is to be taken for the purpose of such dividend,
distribution or right, the date on which the holders of Common Stock shall be
entitled to any such dividend, distribution or right, and the amount and
character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their Warrant Shares for securities or other property
deliverable upon such disposition, dissolution, liquidation or winding up. Each
such written notice shall be sufficiently given if addressed to the Holder at
the last address of the Holder appearing on the books of the Company and
delivered in accordance with Section 17(d). To the extent that the notice
required to be given to the Holder hereunder is material, non-public
information, then such Holder shall sign such confidentiality agreement with the
Company as it or its counsel may reasonably require to protect against the
premature disclosure of such event.

     16. Authorized Shares. The Company covenants that during the period the
Warrant is outstanding, it will reserve from its authorized and unissued Common
Stock a sufficient number of shares to provide for the issuance of the Warrant
Shares upon the exercise of any purchase rights under this Warrant. The Company
further covenants that its issuance of this Warrant shall constitute full
authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such
Warrant Shares may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of the Principal Market
upon which the Common Stock may be listed.

          The Company shall not by any action, including, without limitation,
amending its certificate of incorporation or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, but will at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such actions as may be necessary or appropriate to protect the rights of the
Holder against impairment. Without limiting the generality of the foregoing, the
Company will (a) not increase the par value of any Warrant Shares above the
amount payable therefor upon such exercise immediately prior to such increase in
par value, (b) take all such action as may be necessary or appropriate in order
that the Company may validly and legally issue fully paid and nonassessable
Warrant Shares, and (c) use all commercially reasonable efforts to obtain all
such authorizations, exemptions or



                                       7



consents from any public regulatory body having jurisdiction thereof as may be
necessary to enable the Company to perform its obligations under this Warrant.

          Upon the request of the Holder, the Company will at any time during
the period this Warrant is outstanding acknowledge in writing, in form
reasonably satisfactory to Holder, the continuing validity of this Warrant and
the obligations of the Company hereunder.

          Before taking any action which would cause an adjustment reducing the
current Exercise Price below the then par value, if any, of the Warrant Shares,
the Company shall take any corporate action which may be necessary in order that
the Company may validly and legally issue fully paid and non-assessable shares
of such Common Stock at such adjusted Exercise Price.

          Before taking any action which would result in an adjustment in the
number of Warrant Shares for which this Warrant is exercisable or in the
Exercise Price, the Company shall obtain all such authorizations or exemptions
thereof, or consents thereto, as may be necessary from any public regulatory
body or bodies having jurisdiction thereof.

     17. Miscellaneous.

         (a)  Jurisdiction. This Warrant shall constitute a contract under the
     laws of New York, without regard to its conflict of law, principles or
     rules, and be subject to arbitration pursuant to the terms set forth in the
     Purchase Agreement.

         (b)  Restrictions. The Holder acknowledges that the Warrant Shares
     acquired upon the exercise of this Warrant, if not registered, will have
     restrictions upon resale imposed by state and federal securities laws.

         (c)  Nonwaiver and Expenses. No course of dealing or any delay or
     failure to exercise any right hereunder on the part of Holder shall operate
     as a waiver of such right or otherwise prejudice Holder's rights, powers or
     remedies, notwithstanding all rights hereunder terminate on the Termination
     Date. If the Company fails to comply with any material provision of this
     Warrant, the Company shall pay to the Holder such amounts as shall be
     sufficient to cover any costs and expenses including, but not limited to,
     reasonable attorneys' fees, including those of appellate proceedings,
     incurred by Holder in collecting any amounts due pursuant hereto or in
     otherwise enforcing any of its rights, powers or remedies hereunder.

         (d)  Notices. Any notice, request or other document required or
     permitted to be given or delivered to the Holder by the Company shall be
     delivered in accordance with the notice provisions of the Purchase
     Agreement.

         (e)  Limitation of Liability. No provision hereof, in the absence of
     affirmative action by the Holder to purchase Warrant Shares, and no
     enumeration herein of the rights or privileges of Holder, shall give rise
     to any liability of Holder for the purchase price of any Common Stock or as
     a stockholder of the Company, whether such liability is asserted by the
     Company or by creditors of the Company.



                                       8



         (f)  Remedies. Holder, in addition to being entitled to exercise all
     rights granted by law, including recovery of damages, will be entitled to
     specific performance of its rights under this Warrant. The Company agrees
     that monetary damages would not be adequate compensation for any loss
     incurred by reason of a breach by it of the provisions of this Warrant and
     hereby agrees to waive the defense in any action for specific performance
     that a remedy at law would be adequate.

        (g)  Successors and Assigns. Subject to applicable securities laws,
     this Warrant and the rights and obligations evidenced hereby shall inure to
     the benefit of and be binding upon the successors of the Company and the
     successors and permitted assigns of the Holder. The provisions of this
     Warrant are intended to be for the benefit of all Holders from time to time
     of this Warrant and shall be enforceable by any such Holder.


         (h)  Indemnification. The Company agrees to indemnify and hold harmless
     the Holder from and against any liabilities, obligations, losses, damages,
     penalties, actions, judgments, suits, claims, costs, attorneys' fees,
     expenses and disbursements of any kind which may be imposed upon, incurred
     by or asserted against the Holder in any manner relating to or arising out
     of any failure by the Company to perform or observe in any material respect
     any of its covenants, agreements, undertakings or obligations set forth in
     this Warrant; provided, however, that the Company will not be liable
     hereunder to the extent that any liabilities, obligations, losses, damages,
     penalties, actions, judgments, suits, claims, costs, attorneys' fees,
     expenses or disbursements are found in a final non-appealable judgment by a
     court to have resulted from the Holder's negligence, bad faith or willful
     misconduct in its capacity as a stockholder or warrantholder of the
     Company.

         (i)  Amendment. This Warrant may be modified or amended or the
     provisions hereof waived with the written consent of the Company and the
     Holder.

         (j)  Severability. Wherever possible, each provision of this Warrant
     shall be interpreted in such manner as to be effective and valid under
     applicable law, but if any provision of this Warrant shall be prohibited by
     or invalid under applicable law, such provision shall be ineffective to the
     extent of such prohibition or invalidity, without invalidating the
     remainder of such provisions or the remaining provisions of this Warrant.

         (k)  Headings. The headings used in this Warrant are for the
     convenience of reference only and shall not, for any purpose, be deemed a
     part of this Warrant.

its officer thereunto duly authorized.

To:  World Wide Wireless Communications, Inc.


     (1) The undersigned hereby elects to purchase ________ Warrant Shares (the
"Common Stock"), of World Wide Wireless Communications, Inc. pursuant to the

Gentlemen:

     The undersigned, registered Holder of the Warrant delivered herewith,
hereby irrevocably exercises such Warrant for, and purchases thereunder, shares
of the Common Stock of World Wide Wireless Communications, Inc., a Delaware
corporation, as provided below. Capitalized terms used herein, unless otherwise
defined herein, shall have the meanings given in the Warrant. The portion of the
Exercise Price (as defined in the Warrant) to be applied toward the purchase of
Common Stock pursuant to this Notice of Exercise is $_______, thereby leaving a
remaining Exercise Price (if any) equal to $________. Such exercise shall be
pursuant to the cashless exercise provisions of Section 3 of the Warrant;
therefore, Holder makes no payment with this Notice of Exercise. The number of
shares to be issued pursuant to this exercise shall be determined by reference
to the formula in Section 3 of the Warrant which, by reference to Section 3,
requires the use of the high and low trading price of the Company's Common Stock
on the Trading Day preceding the date of such election. The high and low trading
price of the Company's Common Stock has been determined by Holder to be $______
and $_________, respectively, which figure is acceptable to Holder for
calculations of the number of shares of Common Stock issuable pursuant to this
Notice of Exercise. Holder requests that the certificates for the purchased
shares of Common Stock be issued in the name of _________________________ and
delivered to ______________________________________________. To the extent the
foregoing exercise is for less than the full Aggregate Price of the Warrant, a
replacement Warrant representing the remainder of the Aggregate Price (and
otherwise of like form, tenor and effect) shall be delivered



                                       2




to Holder along with the share certificate evidencing the Common Stock issued in
response to this Notice of Exercise.
