Nokia Siemens Networks has introduced two new applications, Energy Efficient Coverage and Configurable Carrier Bandwidth that allow mobile broadband operators to deliver better services with their existing spectrum.

The new applications form part of the company’s Liquid Radio GSM software suite, an application for frequency re farming that ensures flexibility in using limited GSM spectrum efficiently.

Energy Efficient Coverage (EEC) enables existing GSM spectrum to support up to double the amount of traffic, the company said.

It can also achieve the same GSM performance using less spectrum, freeing up more frequencies for WCDMA re-farming. It also improves network coverage.

Configurable Carrier Bandwidth for WCDMA that allows WCDMA carrier bandwidth to be set in software configurable steps of 200 kHz from the 3.8 MHz up to 4.2 MHz, depending on an operator’s spectrum.

It gives operators the flexibility to allocate more GSM spectrum to WCDMA as it becomes available. The feature also allows co-location of GSM and WCDMA on the same frequency band for operators with limited spectrum.

Operators can deploy the features with Nokia Siemens Networks’ Single RAN platform via software upgrade to evolve their networks manage the growth in mobile broadband traffic.

Nokia Siemens Networks offers planning and implementation services for WCDMA and LTE re-farming to help operators increase network capacity and improve network performance.

Nokia Siemens Networks North America Mobile Broadband Sales Development head Dhruv Khanna said, "Our software suite addresses this challenge. Operators can re-farm using much narrower spectrum than before, deliver GSM and WCDMA with 30% less spectrum, and also lower total cost of ownership by 20%. Moreover, they can deliver a vastly improved user experience, and potentially attract more customers to increase revenues."
