AMG4.6 and LSF2.1

AMG4.6
We have clearly demonstrated our ability to provide both single and multiple TRX remote system which generates a positive Return On Investment for GSM operators and helps them meet their universal Service Obligations for small communities (100 to 200 users) with a relatively high ARPU of 10$ to $20. With the release of AMG4.6, Altobridge will further enhance its product offering by enabling customers to use a wide variety of bandwidth terminals thereby allowing them to extend their market penetration as the end customer needs dictate. Altobridge will further refine and improve the existing backhaul bandwidth savings to be made through the implementation of the Channel Quenching feature.

LSF2.1
This project has the following benefits:

• Cellular operators using satellite Abis or terrestrial Abis can achieve significant savings. Consider a scenario where an operator wants to deploy additional coverage in a remote community where typical backhaul is limited or difficult to install. The only option may be to use expensive satellite links. LS minimizes the amount of traffic over the backhaul, which allows the operator to deploy coverage costs effectively. Using LS the costs related to leasing Satellite bandwidth can be reduced by up to 70%.
• First mover advantage – this is where an operator is the first to deploy GSM coverage together with LS in a rural area where majority of traffic is voice. LS allows the operator to secure maximum savings as all local calls are on the same network.
• Existing sites can be easily migrated to LS with reduced backhaul costs.
• Sites can be extended without the need to increase backhaul capacity.
• The existing network architecture and business model remains unaffected by implementing LS.
• The core network remains in control of the call and in control of all charging.
• Existing features and services of the existing core network are seamlessly preserved for subscribers.
• No modification is necessary to the existing BTS and BSC.
• There are reduced backhaul requirements for large “Special Events” or “Exhibition” sites.
• Potential increase in voice traffic as the voice quality is considerably better for local calls than backhauled calls. Typically customers stay on calls longer when call quality is good.

The LS solution offers a significant reduction in operating expenditure of GSM sites as a percentage of calls are locally switched, reducing satellite and terrestrial bandwidth requirement. This results in extra savings for the operator. Satellite bandwidth requirements are further reduced by optimisation of the Abis over IP.

The following codecs are supported:

• Full Rate (FR)
• Half Rate (HR)
• Enhanced Full Rate (EFR)
• All AMR codecs

LS supports intra cell handover and Inter cell handover within the RGW. This means that the call remains locally switched after the handover. If one of the parties on a locally switched call requires handover to a cell outside of the RGW, the call is handed back to the network.
