Software defined radio aids 3GPP-LTE compliance

Sorbas110 is a prototype user equipment that enables basestation developers to test their designs against a reference mobile terminal even though the 3GPP-LTE standard has not been finalised.

3GPP-LTE (Long Term Evolution), a cellular standard currently slated as the successor of current UMTS technology, will be able to transfer data at a peak rate of 100Mbit/s.

This new technology for cellular network access will enhance the current W-CDMA standard with OFDM technology and will coexist with 2G and 3G networks.

3GPP-LTE radio networks are expected to be ready for the market by 2010.

The new standard ensures the long-term competitiveness of UMTS.

It will enable new services such as the delivery of high-definition videos to mobile devices.

The 3GPP-LTE standardisation is still ongoing.

Signalion is a pioneer among the growing infrastructure of companies supporting 3GPP-LTE, and the company's Sorbas110 is billed as the first test solution for LTE basestations.

Sorbas110 is a prototype user equipment (UE) that enables basestation developers to test their designs against a reference mobile terminal even though the 3GPP-LTE standard has not been finalised.

Software defined radio (SDR) concepts enable the system to keep up with standard changes continuously.

A scalable hardware platform with a four-channel RF front end provides the processing power needed for advanced technologies such as MIMO, beamforming and HARQ.

The current implementation focuses on Layers 1 and 2.

Layer 3 functionality will be added in the future.

At the 3GSM World Congress 2007 in Barcelona, Signalion's LTE test UE will be used in demonstrations by both Rohde and Schwarz and Alcatel-Lucent.

Rohde and Schwarz will demonstrate live video transmission using the 3GPP-LTE standard.

R and S is among the front-runners working toward the next generation of mobile radio.

At the 3GSM World Congress 2007 the company will present solutions for analysing and generating 3GPP-LTE signals in the downlink and in the uplink by using the R and S FSQ signal analyser and the R and S SMU200A signal generator.

Signalion offers complete 3GPP-LTE solutions from one source, combining: the Sorbas platform, a growing stack of intellectual property, and dedicated consulting services for 3GPP-LTE.

This enables the developers to keep up with the ongoing standardisation and saves development time and costs.
