POWER OF ATTORNEY

	KNOW ALL MEN BY THESE PRESENTS, that I, the undersigned
Randall Hack, hereby constitute and appoint Thomas A. Scott, my
true and lawful attorney-in-fact as follows:

	1.	To execute for me and on my behalf in my capacity as a
		director of FiberTower Corporation, a Delaware
		corporation (the "Company"), Forms 3, 4 and 5 and any
		amendments thereto in accordance with Section 16(a) of
		the Securities Exchange Act of 1934 (the "Act") and the
		rules thereunder;

	2.	To do and perform any and all acts for me and on my
		behalf that may be necessary or desirable to complete
		and execute any such Forms 3, 4 or 5 and timely file
		such form with the United States Securities and Exchange
		Commission and any stock exchange or similar authority;
		and

	3.	To take any other action of any type whatsoever in
		connection with the foregoing that, in the opinion of
		such attorney-in-fact may be of benefit to, in the best
		interest of, or legally required of me, it being
		understood that the documents executed by such attorney-
		in-fact on my behalf pursuant to this Power of Attorney
		shall be in such form and shall contain such terms and
		conditions as such attorney-in-fact may approve in his
		discretion.

	I hereby grant to such attorney-in-fact full power and
authority to do and perform each and every act and thing
whatsoever requisite, necessary or proper in the exercise of any
of the rights and powers granted herein as fully to all intents
and purposes as I might or could do in person, with full power of
substitution and revocation, hereby ratifying and confirming all
that such attorney-in-fact or his substitute or substitutes shall
lawfully do or cause to be done by virtue of this Power of
Attorney.  I acknowledge that the foregoing attorney-in-fact in
serving in such capacity at my request is not assuming, and the
Company is not assuming, any of my responsibilities to comply with
Section 16 of the Act.

	This Power of Attorney shall remain in full force and effect
until I am no longer required to file Forms 3, 4 and 5 with
respect to my holdings of, and any transactions in, securities
issued by the Company, unless earlier revoked by me in a signed
writing delivered to the foregoing attorney-in-fact.

	IN WITNESS WHEREOF, I have executed this Power of Attorney
as of this 7th day of February 2007.
