RE: Purpose of Proposed Experimental License
     IWL Communications Inc. DBA CapRock Services Corp.
     Houston, Texas
     1.8 Meter and 2.4 Meter C-band Transmit Earth Station(s)

IWL Communications Inc. DBA CapRock Services Corp. has the need to test and
validate satellite earth station transmitting and antenna equipment combinations
at their Houston, Texas facility, prior to shipping the products to customers.
The satellite earth station equipment will be used for testing purposes only and
not to establish permanent communications links from this facility.
An interference analysis of the shared C-band spectrum (5925 – 6425 MHz) has been
completed and indicates that no local 6 GHz terrestrial microwave receivers will
be impacted by the low power testing of the 1.8 and 2.4 meter C-band earth
station antennas. A copy of the interference analysis report is attached to the
experimental license application request.

No formal frequency coordination was completed for these antennas, since they
will not be used to establish temporary or permanent communications links from
this facility. Further justification for not coordinating these antennas, is
based on the fact that the Houston facility has existing large diameter C-band
uplinks already under coordination, that should serve as notification and
protection to the existing 6 GHz terrestrial microwave community.
