A satellite backhaul optimization solution to reduce bandwidth consumption for transporting cellular traffic between GSM cell sites and base station controllers over costly satellite links.

Our Solution

RAD’s satellite backhaul optimization solution enables mobile operators to improve GSM backhaul efficiency over expensive satellite links, thereby saving on OpEx.

Supporting both point-to-point satellite backhaul and point-to-multipoint satellite backhaul over TDM or IP networks, RAD’s satellite backhaul optimization solution multiplexes and reduces bandwidth consumption by 3:1 by eliminating redundant and idle frames on the Abis and Ater interfaces.

The Vmux-400 GSM Abis/Ater optimization gateway reduces the number of E1 trunks required for BTS-BSC and BSC-MSC backhaul by 50% and more, freeing up the backhaul connection for additional traffic or next generation services.

The Vmux-400 GSM optimizes GSM Abis/Ater traffic and transports it over an E1/T1, serial or 10/100BaseT Ethernet link.

Compression technology is used to further optimize satellite backhaul by deploying the Vmux-2100 voice trunking gateway on MSC-PSTN traffic (E interface) over satellite.

Benefits

• Up to 50 percent bandwidth savings

• Quick payback

• Supports optimization for any codec: HR, FR, EFR, AMR

• Enable controlled introduction of early 3G services with no additional capital investments
