Tools to benchmark and validate new equipment for leading LTE Mobile Access Network
Newbury Park January 12th, 2012 - Absolute Analysis today announced it has been selected by a major Asian mobile communications service provider to support their mobile backhaul 4G LTE deployment.
Quality of service (QoS) is paramount to the success of today's mobile service providers. Consequently they must thoroughly test and validate the performance and reliability of all equipment that is to be used in their Mobile Access Network. The Mobile Access Network refers to the edge of the service provider's network used in connecting Remote Radio Heads (RRH) to centralized Base Band Units (BBU). Networks with distributed antennas helps to both reduce operating costs while also improving signal quality. New technologies that leverage protocol standards such as CPRI and OBSAI now allow service providers to distribute radio antennas across their network achieving both economic and performance gains as a result. In order for Radio Heads and Base Stations to operate in separate locations stringent network performance thresholds must be met. Typical implementations also include optical multiplexors and transponders providing instant failover redundancy in the event of link failure.
Absolute Analysis LTE performance test equipment has been used to benchmark the performance of network equipment providers competing for their place in the new LTE network. Real-time statistical measurements are made in both laboratory testing as well as field deployments. This helps ensure that access network equipment complies with LTE and WiMax specifications for performance and interoperability between devices in both normal and failover modes. Network impairments, data link bottlenecks, and cabling issues are identified through a simple GUI that provides real-time latency, recovery or failover delay, and bit error rate measurements, across multiple points in the network, over both copper and optical media. The Absolute Analysis equipment also includes capabilities for capture and decode of network traffic providing precise details of problem areas.
"The selection by a major mobile service provider further validates our solution approach to the market." says Dennis Murphy, CEO of Absolute Analysis. "Close cooperation between our engineering team and the customer and their hardware vendors yielded a solution that guarantees the interoperability, reliability and performance of their Mobile Access Network."
