ITEM 4      CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT

            On June 12, 2002, Aether Systems, Inc., a Delaware corporation (the
"Company"), determined not to retain Ernst & Young LLP ("Ernst & Young") as
independent accountants for its subsidiary Sila Communications Limited, a
limited company incorporated under the laws of England and Wales ("Sila"), and
determined to engage KPMG LLP ("KPMG"), the Company's independent auditor, as
Sila's new independent auditor. The change in independent accountants became
effective June 12, 2002. The decision not to retain Ernst & Young and to engage
KPMG was recommended by the Company's Audit Committee and approved by Sila's
Board of Directors.

            Ernst & Young's reports on the financial statements of Sila did not,
in either of the past two fiscal years, contain an adverse opinion or disclaimer
of opinion, and were not qualified or modified as to uncertainty, audit scope,
or accounting principles.

            During Sila's two most recent fiscal years and the subsequent
interim period between December 31, 2001 and June 12, 2002, there were no
"reportable events" (as defined in Item 304(a)(1)(v) of Regulation S-K
promulgated by the Securities and Exchange Commission).

            During Sila's two most recent fiscal years and the subsequent
interim period between December 31, 2001 and June 12, 2002, there were no
disagreements with Ernst & Young on any matter of accounting principles or
practices, financial statement disclosure, or auditing scope or procedure, which
disagreements, if not resolved to the satisfaction of such accountant, would
have caused Ernst & Young to make reference to the subject matter of the
disagreement in connection with its report.

            The Company provided Ernst & Young with a copy of the foregoing
disclosures in advance of the day that these disclosures were filed by the
Company with the SEC. Attached as Exhibit 16.1 to this Current Report on Form
8-K is a copy of Ernst & Young's letter, dated June 12, 2002, stating its
agreement with such statements.

            During Sila's two most recent fiscal years and the subsequent
interim period between December 31, 2001 and June 12, 2002, neither Sila nor the
Company consulted with KPMG regarding any of the matters or events described in
Item 304(a)(2)(i) or (ii) of Regulation S-K.
