Ladies and Gentlemen:

Reference is made to the effective Registration Statements on Form S-3, file
numbers 333-99770, 333-3334 and 333-12133, and the Registration Statement on
Form S-3, file number 333-21987 (collectively, the "Registration Statements")
filed with the Securities and Exchange Commission (the "Commission") on
February 19, 1997 by CAI Wireless Systems, Inc. (the "Issuer").

Application is hereby made by the Issuer to the Commission to withdraw the
Registration Statements, together with the exhibits and amendments thereto,
pursuant to Rule 477 under the Securities Act of 1933, as amended (the " 33
Act") and to deregister the unsold shares identified thereon.  The Registration
Statements were filed on behalf of a number of the Issuer's securityholders,
the majority of whom may now avail themselves of Rule 144 promulgated under the
 33 Act to offer and sell the Issuer's common stock held by them and listed on
the Registration Statements.  Additionally, by withdrawing the Registration
Statements at this time, the Issuer seeks to save the expense associated
with maintaining the effectiveness of a registration statement.

Kindly direct any questions you have regarding Issuer's request to withdraw the
Registration Statements to the undersigned at (518) 462-2632.

Very truly yours,


James P. Ashman
Executive Vice President and
 Chief Financial Officer
