ABIS Optimization Benefits

Cellular Base Station Backhaul with ABIS

The Abis protocol, which is specifically designed for cellular communication links, can be optimized which minimizes the bandwidth required to interconnect. The network can then carry additional service traffic between the Base Station and the Base Station Controller. Significant cost savings are possible by reducing the requirements for new infrastructure and maximizing the utilization of existing backhaul circuits.

Optimized Abis Over Satellite

The IP•Tube G4 Abis enables Satellite Service Providers to efficiently tap into the multi-billion dollar GSM mobile operator backhaul service business. GSM operators are expanding from urban areas to rural and remote areas with lower Average Revenue Per User, especially in economically emerging countries.

Satellite transmission offers the proven solution for quickly reaching smaller, remote and dispersed communities, and delivering reliable connectivity, provided that the cost is right. The high Opex associated with satellite transponder usage lowers the profitability of such deployment, limiting its application to specific cases and interim fast service coverage deployment.

Engage’s Abis Optimization, which can achieve a 50% reduction in the bandwidth required for GSM BTS satellite backhaul, makes it possible to provide mobile services to locations that are revenue challenged.

Optimized Abis Over Wireless Ethernet

For over Ten years the IP•Tube has proven itself around the world as an effective method for using Commercial Off the Shelf Wireless Ethernet Bridges, such as 802.x and WiMax, to backhaul T1/E1 Base Station traffic.

Abis optimization facilitates more robust Wireless Ethernet by freeing up bandwidth so wireless retransmission protocols can be effective.
The IPTube’s Assured Delivery Protocol, for example, has the sophistication required to create solid performance across a wide range of wireless connections.

Since the majority of Wireless Radios are half duplex, with limited packet forwarding rates,, the IP Tube also has the ability to multiplex multiple T1/E1 circuits into a single packet further reducing packet rate and over head by up to 75%.

Combine up to 2 T1/E1 backhaul circuits over a single TDM link

The IP•Tube G4 Abis can provide 50% total bandwidth reduction on a per TDM circuit basis. This can mean the ability to combine added T1 or E1 circuits on existing backhaul circuits without additional installation of equipment for the backhaul network.

The Abis compression option means valuable savings when adding just a few more data or voice circuits per Base Station. It permits a economical solution for adapting exisiting remote mobile sites to future data oriented service offerings. With the IP•Tube G4 ABIS optimization additional backhaul infrastructure is made available at a fraction of the cost of installing new backhaul network equipment.

Optimized Abis Over Circuits
With configurable Abis optimization the number of T1/E1 circuits or timeslots required for backhaul is reduced by as much as 2:1 which saves precious Opex, especially if leased from another service provider. Or, with the additional capacity created, bandwidth is now available for a higher base station traffic load without additional T1/E1 Capex or Opex investment.

Optimized Abis over Broadband IP Ethernet

Abis Over IP works with a wide variety of Broadband Ethernet and IP packet service offerings: MPLS, Metro Ethernet, HFC Cable, xDSL, etc. The bandwidth required to transport a single full T1/E1 circuit with low latency IP packets without Abis Optimization consumes up to 2.5 Mbps and 4 E1s requires 10 Mbps.

Voice communication is typically half duplex, where one individual talks while the other listens. Thus, Abis optimization typically reduces IP/Ethernet bandwidth by 50% and during non peak times when the cell traffic is idle bandwidth is reduced by up to 90%.

Fixed Abis optimization enables the use of last mile connections, such as ubiquitous DSL, with bandwidth significantly less than the number of 64 Kbps T1/E1 timeslots used by the Base Station.

Dynamic Abis optimization reduces the committed information rate needed from the Broadband Ethernet Service provider by more than 50% for each base station connected. This bandwidth reduction also minimizes the aggregate Ethernet bandwidth and equipment required to connect to the Base Station Controller T1/E1 circuits.
