Local Switching

The Local Switching solution offered by Cell & Sat significantly reduces the cost of operating remote cellular base stations. It complements the silence reduction and bandwidth gains of compression products, and detects situations where speech communications can be routed locally to avoid unnecessary transmission back in the network.

Local Switching is performed at the interface with the BTS. During a conversation between two mobile terminals connected to the same satellite terminal, only the information is transmitted while the voice traffic is routed locally. At the interface with the BSC, silence frames are generated and transmitted with the signalling to achieve full interoperability with the GSM network.

The Local Switching combined with optimization solution reduces the satellite costs by a factor as high as 60% and improves the speech quality by avoiding double satellite hops.

Cell & Sat accompanies you during the process of setting up from feasibility study to deployment. Our tools are used to assess the relevance of local switching on your local network based on potential traffic and simulate your economy satellite bandwidth.
