I, Michael F Manion certify that:

1. I was appointed President and Director of eCHEX Worldwide Corp. on March 16,
2004. Prior to that time I was a consultant to the company and other interested
parties regarding the use of a publicly registered entity emerging from
bankruptcy for achieving public ownership status for a new formed entity. I have
limited knowledge of the company's affairs prior to my appointment and have
relied on representations of the prior management and other consultants to the
company concerning the business affairs and operations of the company prior to
this date to make the following certifications. The company has been under the
protection of the Bankruptcy Court since September 11, 2002. It sold its
operating assets on October 18, 2002. It had no operations during fiscal 2003
and reported its cash receipts and disbursements monthly to the Office of the
United States Trustee.

2. I have reviewed this annual report on Form 10-KSB of Worldwide Wireless
Networks, Inc.

3. Based on my knowledge, this annual report does not contain any untrue
statement of a material fact or omit to state a material fact necessary to make
the statements made, in light of the circumstances under which such statements
were made, not misleading with respect to the period covered by this annual
report;

4. Based on my knowledge, the financial statements, and other financial
information included in this annual report, fairly present in all material
respects the financial condition, results of operations and cash flows of the
registrant as of, and for, the periods presented in this annual report;

5. The registrant's other certifying officer and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-14 and 15d-14) for the registrant from the date of my
appointment and have to the extent necessary and based on the information
available, have:

     a) designed such disclosure controls and procedures to ensure that material
     information relating to the registrant, including its consolidated
     subsidiaries, is made known to us by others within those entities,
     particularly during the period in which this annual report is being
     prepared;

     b) evaluated the effectiveness of the registrant's disclosure controls and
     procedures as of a date within 90 days prior to the filing date of this
     annual report (the "Evaluation Date"); and

     c) presented in this annual report our conclusions about the effectiveness
     of the disclosure controls and procedures based on our evaluation as of the
     Evaluation Date;

6. The registrant's other certifying officer and I have disclosed, based on our
most recent evaluation, to the registrant's auditors and the audit committee  of
the registrant's board of directors (or persons performing the equivalent
functions) (as of December 22, 2003 the company had a single director which
acted in all capacities):

     a) all significant deficiencies in the design or operation of internal
     controls which could adversely affect the registrant's ability to record,
     process, summarize and report financial data and have identified for the
     registrant's auditors any material weaknesses (if any) in internal
     controls; and

     b) any fraud (if any), whether or not material, that involves management or
     other employees who have a significant role in the registrant's internal
     controls; and

6. The registrant's other certifying officers and I have indicated in this
annual report whether there were significant changes in internal controls or in
other factors that could significantly affect internal controls subsequent to
the date of our most recent evaluation, including any corrective actions with
regard to significant deficiencies and material weaknesses.
