Satellite communication systems and methods are disclosed that provide local and regional data to a subscriber terminal utilizing a single receiver. Regional data may be transmitted over a wide beam and the local data may be transmitted over one of a plurality of localized spot beams such as, for example, a four color spot pattern. Moreover, the data may be multiplexed using TDMA, FDMA, and/or OFDMA techniques. In one embodiment, the regional data is transmitted in a first time slot over a first frequency band and the local data is transmitted in a second timeslot. Each set of localized data may be transmitted over a sub-band of the first frequency band. |
