Experiment Description

An Experimental STA is requested in order to support a demonstration of ancillary voice
communications in addition to the Internet data capability of our satellite
communications equipment offering.

The demonstration will take place April 27th, 2011 at the FCC headquarters building in
Washington, D.C. and will be attended by a number of Sr. Commission staff.

The equipment to be used in support of the demonstration, for which this Experimental
STA is requested, is a femto-cell device which has been approved for commercial
operation in Europe and Japan. The device allows regular cell phones to communicate
over an IP data link when normal cellular telephone service is not available, i.e. inside
buildings or in rural or remote areas with poor or non-existent cellular service.

The device is capable of operation on a number of different frequency bands. Band 1 is
1920 – 1980 MHz, band 2 is 1850 – 1910 MHz, and band 5 is 824 – 849 MHz. The
actual frequency used will be limited to a single 5 MHz wide channel within one of the
above bands that can be selected at the time of the demo. Currently, the band of operation
planned for the demo is band 1.

The device operates at very low power, with a maximum output of 10 dBm into a 0 dBi (-
2.14 dBd) gain Omni directional antenna. The output power is variable and is reduced to
less than the maximum when in communicating with cellular handsets near by.

The point of contact to cease transmissions is Daryl Hunter and the phone number is 1-
760-476-2583.
