Justification and Fixed Location Information

This STA is required so that the Applicant can evaluate Nokia Siemens Network (NSN) prototype
equipment as a candidate for commercial deployment as part of the Applicant’s WiMAX
deployment. This equipment will be used to conduct over-the-air testing in the Applicant’s
Arlington Virginia Test Cluster. The equipment will be tested and evaluated on a variety of
aspects, including compatibility with other WiMAX devices, performance and coverage in a mixed
residential/commercial environment, hand-off capabilities between cells, and reliability. The
equipment has not yet received an FCC grant of equipment authorization (certification). While
the FCC rules, Section 2.803(e)(1)(v) permits radio devices to be operated prior to equipment
authorization for evaluation of product performance and determination of customer acceptability,
such operations are limited to non-residential locations. It is important, however, for this
equipment to be tested in both commercial and residential environments in order to fully assess
its suitability of eventual commercial deployment. The Arlington Virginia Test Cluster has been
established just for this purpose. The Applicant anticipates deploying commercial service in the
Washington, DC area, including the Arlington Virginia Test Cluster, in the near future; thus, quick
approval of this Application is requested so that the testing and evaluation can be completed.
The Applicant believes that the equipment complies with all of the FCC’s requirements for
equipment authorization and does not, therefore, expect any interference to result from this
equipment’s deployment. Furthermore, this equipment will be operated only on frequencies
within the requested frequency band that are controlled throughout the test area (either through
license or lease) by the Applicant, thus minimizing the likelihood of any interference.

At each fixed location, there is a separate Nokia Siemens Networks model SYRE20WATT
transmitter that feeds a KMW Communications model AM-X-WM-17-65-00T antenna for each of
three sectors. The transmitter’s 20 watt output power is split between the two MIMO input ports
on the antenna. A spec sheet for the antenna is attached.
