At the hands of what has become a mobile world, at the center is GSM cellular service. This currently accounts for approximately 80% of the worldwide cellular traffic over CDMA and TDMA. For locations that are outside the reach of fiber and microwave infastructure satellite backhaul for GSM cellular service can be the only choice.

With the majority of major cities now covered by GSM service the challenge has shifted to servicing the rural areas, locations that are beyond the reach of fiber and microwave boundries. To expand the reach of a network, the interface between the BSC and multiple BTSs must be extended in the most efficient manner possible allowing for rapid deployment. This not only meet the needs of mobile users by offering a wider range of coverage as well as servicing new regions but also satisfies regulatory requirements of obtaining licensing. In response power partnership between Ericsson and iDirect was created.

In the past, such satellite backhaul was serviced with SCPC connections. By nature each connection supports one BTS per frequency channel, requiring each link to be engineered for the busiest hour of traffic which results in a costly solution of unusable bandwidth for non-peak times.

iDirect Technologies and Ericsson have taken the GSM cellular backhaul another level to further develop a more cost effective solution. Ericsson developed a re-engineered A.bis IP interface.

With a little information on your network such as erlangs per site, number of sites and data/signaling information we can turn them into a network design to allow for return on investment analysis.
