ITEM 4      CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT

           Effective June 12, 2002, Aether Systems, Inc., a Delaware corporation
(the "Company"), dismissed 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 engaged KPMG LLP
("KPMG") as Sila's new independent auditor. Because KPMG was the Company's
independent auditor, the Company determined that it was more efficient to have
KPMG serve as auditor of the subsidiary and, in order to comply with statutory
procedures in the United Kingdom, requested that Ernst & Young resign as Sila's
independent auditor. Ernst & Young submitted a resignation letter to Sila's
Board of Directors which Sila's Board of Directors accepted on June 12, 2002;
Sila's Board simultaneously appointed KPMG as Sila's independent auditor. 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/A is a copy of Ernst & Young's letter, dated June 24, 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.
