Wireless backhaul solutions provide reliable high reliability T1/E1 links for connecting your BTS and NodeB sites along with multi-Megabit per second IP connectivity. Rapid deployment and commercially competitive Wireless backhaul solutions provide a viable alternative to traditional E1/T1 methods of connectivity between BSC and BTS nodes in a cellular network.

Cellular systems require carrier-grade communications facilities. It is essential to provide reliable links on the connections between BTS and BSC nodes in the cellular network. With the advent of Wi-FiT based "hot-spots there is an emerging need for both TDM and IP services at many BTS locations in urban and suburban markets. Carriers looking to reduce OPEX can convert some T1/E1 or DS3 lines to wireless.

 

Broadband Fixed Wireless (BFW), platforms to provide a "quick-response" capability where there is a need to deploy required T1/E1 or DS3 facilities and IP facilities in advance of a fibre or copper plant buildout. With your capital investment not buried in the ground but available to be redeployed with minimal effort as required. As carriers examine their readiness in the face of disaster, BFW becomes a strategic option to provide continuity services in the face of landline failures.

Requirement
BTS to BSC connections are a mission critical link for the cellular operator. Many of these links utilize BFW connectivity due to its rapid deployment capability, and the need for operators to reduce OPEX. Increasingly cellular operators worldwide seek to convert ongoing OPEX into one-time CAPEX in order to improve operating results and provide better customer service and overall return to their shareholders.

 

Wireless Advantage
Long-range BFW connections have emerged as an alternative to expensive landline and IP circuits. It is now possible to link one or multiple BTS's to a BSC with high-speed links up to 50 miles long. One initial investment replaces ongoing monthly charges, charges that escalate as your data usage increases.

 

Alternately wireless links can provide a very inexpensive redundant or parallel link to carry voice and data traffic to meet business continuity requirements.

 

Typical Uses

 

• BTS to BSC Wireless Connections
