Cobham Wireless TM500 Network Tester Enhances 4G User Experience

Cobham WirelessCobham Wireless, formerly Aeroflex wireless business unit, has announced that the TM500 network tester family is helping mobile operators to accelerate the deployment of high capacity networks. Already supporting key LTE-A features such as carrier aggregation of two and three component carriers, TDD/FDD carrier aggregation, and eICIC, the TM500 now also supports Coordinated Multipoint transmission/reception (CoMP), a major feature of 3GPP LTE-A Release 11.

Where carriers are deploying small cells, they often do not deliver the expected user experience and this is slowing HetNet deployment. One of the primary reasons for users seeing a degraded quality of service with HetNets is poor cell-edge performance due to the lack of traffic coordination and interference management between small cells and macrocells.

The Cobham Wireless TM500 is already addressing cell-edge interference issues with eICIC (Enhanced Inter-cell Interference Coordination), empowering mobile network operators to achieve better overall network capacity. With the addition of CoMP it will go one step further, by coordinating transmission and reception between different transmitting and receiving cells. It achieves this through the use of load balancing, coordinated scheduling, and the management of signal power and interference. In the downlink, each mobile terminal sees improved data throughput, especially near the cell edges, due to reduced interference and an increase in received power. Similarly, for the uplink, received signal quality and cell edge coverage is improved by simultaneous coordinated reception from different receiving points on the network side.
