Why local loop is important?
Importance of the local loop are connected to the incumbent network. Policy areas such as frequency management, cable laying, sharing physical resources such as cables, poles and ducts and interconnection with other networks are important in achieving competition in the local loop.
What is the maximum data rate support by a GSM?
9.6 kbps
In GSM the maximum data rate is 9.6 kbps per time slot. In GPRS the data is packetized which gives in principle an even lower data rate of 9.05 kbps of which 8 kbps is available for the user.
