 Exhibit 10.4 
  
 THIS NOTE AND THE COMMON SHARES ISSUABLE UPON CONVERSION OF THIS NOTE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, OR ANY STATE SECURITIES LAWS. THIS NOTE AND THE COMMON SHARES ISSUABLE UPON CONVERSION OF THIS NOTE MAY NOT BE SOLD, TRANSFERRED, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THIS

 AMENDED AND RESTATED SECURED CONVERTIBLE MINIMUM BORROWING NOTE

  
 FOR VALUE RECEIVED, each of AIRNET COMMUNICATIONS
CORPORATION, a Delaware corporation (the “Parent”), and the other companies listed on Exhibit A attached hereto (such other companies together with the Parent, each a “Company” and collectively, the
“Companies”), jointly and severally, promises to pay to LAURUS MASTER FUND, LTD., c/o M&C Corporate Services Limited, P.O. Box 309 GT, Ugland House, South Church Street, George Town, Grand Cayman, Cayman Islands, Fax:
345-949-8080 or its registered assigns or successors in interest (collectively, the “Holder”), the sum of Four Million Dollars ($4,000,000) together with any accrued and unpaid interest hereon, on November 8, 2008 (the
“Maturity Date”) if not sooner paid (or converted) hereunder. This note amends and restates in its entirety (and is given in substitution for and not in satisfaction of) that certain $4,000,000 secured convertible minimum borrowing
note made by the Company in favor of Holder on November 8, 2005 and amended and restated as of December 30, 2005. 
  
 Capitalized terms used herein without definition shall have the meanings ascribed to such terms in the Security Agreement among the Companies and the
Holder dated as of the date hereof (as amended, modified and/or supplemented from time to time, the “Security Agreement”). 
  
 The following terms shall apply to this Minimum Borrowing Note (this “Note”): 
  
 ARTICLE I 
 CONTRACT RATE 
  
 1.1 Contract Rate. Subject to Sections 4.2 and 5.10, interest payable on the outstanding principal amount of this Note (the “Principal Amount”) shall accrue at a rate per annum equal to the
“prime rate” published in The Wall Street Journal from time to time (the “Prime Rate”), plus two percent (2%) per annum (the “Contract Rate”). The Contract Rate shall be increased or decreased
as the case may be for each increase or decrease in the Prime Rate in an amount equal to such increase or decrease in the Prime Rate; each change to be 

 
effective as of the day of the change in the Prime Rate. The Contract Rate shall not at any time be less than six percent (6%). Interest shall be
(i) calculated on the basis of a 360 day year, and (ii) payable monthly, in arrears, commencing on December 1, 2005 on the first business day of each consecutive calendar month thereafter through and including the Maturity Date (or
any date of prepayment permitted hereunder or under the Security Agreement) and on the Maturity Date (or any date of prepayment permitted hereunder or under the Security Agreement), whether by acceleration or otherwise. 
  
 1.2 Contract Rate Adjustments and Payments. The Contract Rate shall be
calculated on the last business day of each calendar month hereafter (other than for increases or decreases in the Prime Rate which shall be calculated and become effective in accordance with the terms of Section 1.1) until the Maturity Date
(each a “Determination Date”). 
  
 ARTICLE II

 LOANS; PAYMENTS UNDER THIS NOTE 
  
 2.1 Loans. All Loans evidenced by this Note shall be made in accordance with the terms and provisions of the Security Agreement. 
  
 2.2 No Effective Registration. Notwithstanding anything to the
contrary herein, the Holder shall not be required to accept shares of Common Stock as payment following a conversion by the Holder if there fails to exist an effective current Registration Statement (as defined in the Registration Rights Agreement)
covering the shares of Common Stock to be issued (unless such shares of Common Stock can be transferred under Rule 144 under the Securities Act without regard to volume limitation), or if an Event of Default hereunder exists and is continuing,
unless such requirement is otherwise waived in writing by the Holder in whole or in part at the Holder’s option. 
  
 2.3 Optional Redemption in Cash. The Companies will have the option of prepaying this Note (“Optional Redemption”) by paying to
the Holder a sum of money equal to (a) one hundred twenty percent (120%) of the principal balance of this Note plus (b) accrued but unpaid interest thereon plus (c) any and all other sums due, accrued or payable to
the Holder arising under this Note, the Security Agreement, or any other Ancillary Agreement (the “Redemption Amount”) outstanding on the Redemption Payment Date (as defined below). The Company shall deliver to the Holder a written
notice of redemption (the “Notice of Redemption”) specifying the date for such Optional Redemption (the “Redemption Payment Date”), which date shall be seven (7) days after the date of the Notice of Redemption
(or if such day is not a Business Day, the next succeeding Business Day) (the “Redemption Period”). A Notice of Redemption shall not be effective with respect to any portion of this Note for which the Holder has previously delivered
a Notice of Conversion (defined below) pursuant to Section 3.1, or for conversions elected to be made by the Holder pursuant to Section 3.1 during the Redemption Period. The Redemption Amount shall be determined as if such Holder’s
conversion elections had been completed immediately prior to the date of the Notice of Redemption. On the Redemption Payment Date, the Redemption Amount (plus any additional interest and fees accruing on the Notes during the Redemption Period) must
be irrevocably paid in full in immediately available funds to the Holder. In the event the Companies fail to pay the Redemption Amount on the Redemption Payment Date, then such Redemption Notice shall be null and void.

 ARTICLE III 
 CONVERSION RIGHTS AND FIXED CONVERSION PRICE 
  
 3.1 Optional Conversion. Subject to the terms of Section 2.3 and this Article III, the Holder shall have the right, but not the obligation, at any time until the Maturity Date or during an Event of
Default (as defined in Article IV), and, subject to the limitations set forth in Section 3.2, 3.3 and 3.10 hereof, to convert all or any portion of the outstanding Principal Amount into fully paid and nonassessable shares of the Common Stock at
the Fixed Conversion Price. For purposes hereof, subject to Section 3.6 hereof, the initial “Fixed Conversion Price” means $1.33; notwithstanding the foregoing, if the Fixed Conversion Price as calculated above would be less
than the sum of (i) the closing bid price of the Common Stock on the Principal Market last reported prior to the execution of this Agreement, plus (ii) $0.025 per share to reflect the value of the Warrants under applicable Nasdaq
interpretations (such sum the “Nasdaq Market Calculation”), then the Fixed Conversion Price shall be increased so as to equal the Nasdaq Market Calculation. The shares of Common Stock to be issued upon such conversion are herein referred
to as the “Conversion Shares.” 
  
 3.2
Conversion Limitation. Notwithstanding anything contained herein to the contrary, the Holder shall not be entitled to convert pursuant to the terms of this Note an amount that would be convertible into that number of Conversion Shares
which would exceed the difference between (i) 4.99% of the outstanding shares of Common Stock and (ii) the number of shares of Common Stock beneficially owned by the Holder. For purposes of the immediately preceding sentence, beneficial
ownership shall be determined in accordance with Section 13(d) of the Exchange Act and Regulation 13d-3 thereunder. The Conversion Shares limitation described in this Section 3.2 shall automatically become null and void following notice to
any Company upon the occurrence and during the continuance of an Event of Default, or upon 75 days prior notice to the Parent, except that at no time shall the number of shares of Common Stock beneficially owned by the Holder exceed 19.99% of the
outstanding shares of Common Stock. Notwithstanding anything contained herein to the contrary, the number of shares of Common Stock issuable by the Parent and acquirable by the Holder at an average price below $1.295 per share pursuant to the terms
of this Note, the Security Agreement or any other Ancillary Agreement, shall not exceed an aggregate of 2,520,966 shares of Common Stock (subject to appropriate adjustment for stock splits, stock dividends, or other similar recapitalizations
affecting the Common Stock) (the “Maximum Common Stock Issuance”), unless the issuance of Common Stock hereunder in excess of the Maximum Common Stock Issuance shall first be approved by the Parent’s shareholders. If at any
point in time and from time to time the number of shares of Common Stock issued pursuant to the terms of this Note, the Security Agreement or any other Ancillary Agreement, together with the number of shares of Common Stock that would then be
issuable by the Parent to the Holder in the event of a conversion or exercise pursuant to the terms of this Note, the Security Agreement or any other Ancillary Agreement, would be limited by the preceding sentence, the Parent shall promptly call a
shareholders meeting to solicit shareholder approval for the issuance of the shares of Common Stock hereunder in excess of the Maximum Common Stock Issuance. Notwithstanding anything contained herein to the contrary, the provisions of this
Section 3.2 are irrevocable and may not be waived by the Holder or any Company. 
  

 - 3 - 

 3.3 Mechanics of Holder’s Conversion. (a) In the event that the Holder elects to convert
this Note into Common Stock, the Holder shall give notice of such election by delivering an executed and completed notice of conversion in substantially the form of Exhibit B hereto (appropriately completed) (“Notice of Conversion”)
to the Parent and such Notice of Conversion shall provide a breakdown in reasonable detail of the Principal Amount that is being converted. On each Conversion Date (as hereinafter defined) and in accordance with its Notice of Conversion, the Holder
shall make the appropriate reduction to the Principal Amount as entered in its records and shall provide written notice thereof to the Parent within two (2) Business Days after the Conversion Date. Each date on which a Notice of Conversion is
delivered or telecopied to the Parent in accordance with the provisions hereof (including Section 5.4) shall be deemed a Conversion Date (the “Conversion Date”). Pursuant to the terms of the Notice of Conversion, the Parent
will issue instructions to the transfer agent accompanied by an opinion of counsel (if requested by the Transfer Agent) within three (3) Business Days of the date of the delivery to the Parent of the Notice of Conversion and shall cause (to the
extent it has the ability to cause) the transfer agent to transmit the certificates representing the Conversion Shares to the Holder by crediting the account of the Holder’s designated broker with the Depository Trust Corporation
(“DTC”) through its Deposit Withdrawal Agent Commission (“DWAC”) system within three (3) Business Days after receipt by the Parent of the Notice of Conversion in accordance with Section 5.4 (the
“Delivery Date”). In the case of the exercise of the conversion rights set forth herein the conversion privilege shall be deemed to have been exercised and the Conversion Shares issuable upon such conversion shall be deemed to have
been issued upon the date of receipt by the Parent of the Notice of Conversion. The Holder shall be treated for all purposes as the record holder of the Conversion Shares, unless the Holder provides the Parent written instructions to the contrary.
Any obligations of the Parent under this Section 3.4 are subject to the restrictions on conversions contained in Section 3.2, 3.3 and 3.10 of the Note. 
  
 3.4 Late Payments. Each Company understands that a delay in the delivery of the Conversion Shares in the form
required pursuant to this Article beyond the Delivery Date could result in economic loss to the Holder. As compensation to the Holder for such loss, in addition to all other rights and remedies which the Holder may have under this Note, applicable
law or otherwise, the Companies shall, jointly and severally, pay late payments to the Holder for any late issuance of Conversion Shares in the form required pursuant to this Article III upon conversion of this Note, in the amount equal to $250 per
Business Day after the Delivery Date. The Companies shall, jointly and severally, make any payments incurred under this Section in immediately available funds upon demand. 
  
 3.5 Conversion Mechanics. The number of shares of Common Stock to be issued upon each conversion of this Note shall
be determined by dividing that portion of the principal to be converted, if any, by the then applicable Fixed Conversion Price. 
  
 3.6 Adjustment Provisions. The Fixed Conversion Price and number and kind of shares or other securities to be issued upon conversion determined
pursuant to Section 3.1 

  

 - 4 - 

 
shall be subject to adjustment from time to time upon the occurrence of certain events during the period that this conversion right remains outstanding, as
follows: 
  
 (a) Reclassification. If the Parent at any
time shall, by reorganization, reclassification or otherwise, change the Common Stock into the same or a different number of securities of any class or classes, this Note, as to the unpaid Principal Amount, shall thereafter be deemed to evidence the
right to purchase an adjusted number of such securities and kind of securities as would have been issuable as the result of such change with respect to the Common Stock had Holder exercised its applicable conversion rights hereunder immediately
prior to such reorganization, reclassification or other change. 
  
 (b) Stock Splits, Combinations and Dividends. If the shares of Common Stock are subdivided or combined into a greater or smaller number of shares of Common Stock, whether by stock split, reverse stock split or otherwise, or if a
dividend is paid on the Common Stock or any preferred stock issued by the Parent in shares of Common Stock, the Fixed Conversion Price shall be proportionately reduced in case of subdivision of shares or stock dividend or proportionately increased
in the case of combination of shares, in each such case by the ratio which the total number of shares of Common Stock outstanding immediately after such event bears to the total number of shares of Common Stock outstanding immediately prior to such
event. 
  
 (c) Adjustment for Merger or Consolidation. If
at any time while the Note remains outstanding, any consolidation or merger of the Parent with another Person occurs in which the Parent is the continuing or surviving company, the Holder shall have the right upon conversion to receive the kind and
amount of shares or other securities and property receivable by a holder of Common Stock upon such consolidation or merger in exchange for the number of shares of Common Stock that might have been issued upon conversion, immediately prior to such
consolidation or merger. 
  
 3.7 Reservation of Shares.
During the period the conversion right exists, the Parent will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of Conversion Shares upon the full conversion of this Note and the
exercise of the Warrant, subject to the provisions of Section 3.2, 3.3 and 3.10. The Parent represents that upon issuance, the Conversion Shares will be duly and validly issued, fully paid and non-assessable. The Parent agrees that its issuance
of this Note shall constitute full authority to its officers, agents, and transfer agents who are charged with the duty of executing and issuing stock certificates to execute and issue the necessary certificates for the Conversion Shares upon the
conversion of this Note. 
  
 3.8 Registration Rights. The
Holder has been granted registration rights with respect to the Conversion Shares as set forth in a Registration Rights Agreement. 
  
 3.9 Issuance of New Note. Upon any partial conversion of this Note, a new Note containing the same date and provisions of this Note shall, at the
request of the Holder, be issued by the Parent to the Holder for the principal balance of this Note and interest which shall not have been converted or paid. Subject to the provisions of Article IV of this Note, the Parent shall not pay any costs,
fees or any other consideration to the Holder for the production and issuance of a new Note. 
  

 - 5 - 

 3.10 [Intentionally Deleted] 
  
 3.11 Holder not Shareholder. This Note (prior to its conversion) in and of itself does not confer upon the Holder, as
such, any voting rights or other rights or liabilities whatsoever as a shareholder of the Parent, whether such rights or liabilities are asserted by the Holder or its creditors. 
  
 3.12 Benefits of this Note. Nothing in this Note shall be construed to give to any Person other than the
Parent and the Holder any legal or equitable right, or claim under this Note. This Note shall be for the sole and exclusive benefit of the Parent and the Holder. 
  
 ARTICLE IV 
 EVENTS OF DEFAULT AND DEFAULT RELATED PROVISIONS 
  
 4.1 Events of Default. The occurrence of an Event of Default under the Security Agreement shall constitute an event of default (“Event of Default”) hereunder. 
  
 4.2 Default Interest. Following the occurrence and during the
continuance of an Event of Default, the Contract Rate on the outstanding principal balance of this Note shall be one and one-half percent (1.5%) per month, and all outstanding Obligations, including unpaid interest, shall continue to accrue
interest at such interest rate from the date of such Event of Default until the date such Event of Default is cured or waived. 
  
 4.3 Default Payment. Following the occurrence and during the continuance of an Event of Default, the Holder, at its option, may elect, in addition
to all rights and remedies of the Holder under the Security Agreement and the Ancillary Agreements and all obligations of each Company under the Security Agreement and the Ancillary Agreements, to require the Companies, jointly and severally, to
make a Default Payment (“Default Payment”). The Default Payment shall be (a) one hundred twelve percent (112%) of the outstanding principal balance of the Note, plus (b) accrued but unpaid interest, plus
(c) all other fees then remaining unpaid, plus (d) all other amounts payable hereunder. The Default Payment shall be applied first to any fees due and payable to the Holder pursuant to the Notes and/or the Ancillary Agreements, then
to accrued and unpaid interest due on the Notes, the Security Agreement and then to the outstanding principal balance of the Notes. The Default Payment shall be due and payable immediately on the date that the Holder has exercised its rights
pursuant to this Section 4.3. 
  
 ARTICLE V 

MISCELLANEOUS 
  
 5.1 Conversion Privileges. The conversion privileges set forth in Article III shall remain in full force and effect immediately from the date
hereof until the date this Note is indefeasibly paid in full. 
  

 - 6 - 

 5.2 Cumulative Remedies. The remedies under this Note shall be cumulative. 
  
 5.3 Failure or Indulgence Not Waiver. No failure or delay on the part
of the Holder hereof in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any
other right, power or privilege. All rights and remedies existing hereunder are cumulative to, and not exclusive of, any rights or remedies otherwise available. 
  

5.4 Notices. Any notice herein required or permitted to be given shall be in writing and shall be deemed effectively given: (a) upon

 Attn: Stuart Dawley, Vice President and General Counsel 
  

	 	Re:	Amended and Restated Security Agreement Waiver (this “Waiver”) 

  
 Dear Stuart: 
  
 Reference is made to the Security Agreement (as amended, restated, modified or supplemented from time to time, the “Security Agreement”) dated
as of November 8, 2005 and amended and restated as of December 30, 2005 between Laurus Master Fund, Ltd., a Cayman Islands corporation (“Laurus”), and AirNet Communications Corporation, a Delaware corporation (the
“Company”). All capitalized terms used in this letter and not otherwise defined herein shall have the meanings set forth in the Security Agreement. 
  
 Laurus is hereby notifying you of its decision to exercise the discretion granted to it pursuant to Section 2(a)(ii) of the Security Agreement to
make a Loan to the Company in excess of the Formula Amount in effect on the date hereof (the “Overadvance”). In connection with making the Overadvance, for a period beginning on the Closing Date and ending on June 30, 2006 (the
“Period”), Laurus hereby waives compliance with Section 3 of the Security Agreement, but solely as such provision relates to the immediate repayment requirement for Overadvances. Laurus further agrees that solely for such
Period (but not thereafter), (i) the Overadvance shall not trigger an Event of Default under Section 19(a) of the Security Agreement and (ii) notwithstanding anything to the contrary set forth in Section 5(b)(ii) of the Security
Agreement, the Overadvance rate of interest set forth in Section 5(b)(ii) of the Security Agreement (the “Overadvance Rate”) shall not be applicable during the Period; provided that, upon expiration of the Period,
notwithstanding the immediate repayment requirement of the Overadvance at such time as required pursuant to Section 3 of the Security Agreement, the Overadvance Rate shall again be applicable to the outstanding amount of such Overadvance and
such interest shall be payable monthly, in arrears, commencing on July 1, 2006 and continuing thereafter on the first business day of each consecutive calendar month. All other terms and provisions of the Security Agreement and the Ancillary
Agreements remain in full force and effect. 
  
 This Waiver may
not be amended or waived except by an instrument in writing signed by the Company and Laurus. This Waiver may be executed in any number of counterparts, each of 

 
which shall be an original and all of which, when taken together, shall constitute one waiver. Delivery of an executed signature page of this Waiver by
facsimile transmission shall be effective as delivery of a manually executed counterpart hereof or thereof, as the case may be. This Waiver shall be governed by, and construed in accordance with, the laws of the State of New York. This Waiver sets
forth the entire agreement between the parties hereto as to the matters set forth herein and supersede all prior communications, written or oral, with respect to the matters herein. 
  
 If the foregoing meets with your approval please signify your acceptance of the terms hereof by signing below.
