Frequency Plan. The AirStar Release 2.0 will be operated in either the 10 GHz or 26 GHz ETSI frequency plan. The AirStar system now supports the ETSI 26 GHz band 24.5GHz to 26.5GHz with T/R spacing of 1008MHz, 7MHz of step size, supporting 7 MHz or 14 MHz channels.

The table assumes that base station uses the lower duplex frequency for transmit, although this does not need to be the case. In some regions, the upper half of the band may be also used, which is not illustrated here. The ETSI 26GHz band is divided into four bands each corresponding to a unique radio unit model: - Band 1 (downstream 1): 24.5525 - 24.9935GHz - Band 3 (downstream 2): 25.0005 - 25.4415GHz - Band 2 (upstream 1): 25.5605 - 26.0015GHz - Band 4 (upstream 2): 26.0085 - 26.4495GHz With Release 2, the AirStar system supports the ETSI 10 GHz frequency plan in the range 10.15GHz to 10.65GHz, with a T/R spacing of 350MHz and 3.5MHz of step size. The system will be capable of supporting 7 MHz or 14 MHz channels. The associated channel plans for each of the channels are listed below. The AirStar system is configured that the lower duplex frequency is used for Base Station transmit, higher duplex frequency is used for Base Station receive. Vice verse for Subscriber terminals. The center frequencies are in Table 2-2: ETSI 10 GHz Channel Plan.

Frequency Plan. If Purchaser intends to modify its then current operating frequency plan, Purchaser shall coordinate with GTE's Satellite Services Engineering department to develop an optimum frequency plan, including power levels, which considers traffic on the cross-polarized and adjacent transponders, and on the co-polarized transponder(s) on the adjacent satellite(s). Any proposed changes in the frequency plan must be submitted thirty (30) days prior to initiation of the change. This information is required in order for GTE Spacenet to maintain a minimized interference environment for the Purchaser and for other users of the assigned satellite.
