ZTE deploys GSM and LTE in one channel to improve spectrum efficiency by up to 50%

ZTE Corporation has found a way to combine GSM and LTE spectrum in one band to significantly enhance spectrum utilisation and improve efficiency by up to 50%.

The ZTE Magic Radio Spectrum Solution achieves GSM/LTE dual mode in the 900/1800MHz bands through the utilisation of existing GSM macro sites. Because of this, in-use GSM voice services are not affected while high-rate data services are still available. The solution accelerates commercial LTE deployments and lowers construction, operations and management costs, according to ZTE.

The spectrum solution contains two sub-solutions: the G/L spectrum overlay solution and G/L collaborated spectrum scheduling solution. The former allows GSM and LTE to occupy some identical frequencies simultaneously. This maximises GSM and LTE capacity. The latter dynamically schedules the amount of spectrum resource used by GSM and LTE. When these two sub-solutions are deployed simultaneously, spectrum efficiency can be improved by up to 50%.

“We see the Magic Spectrum Solution as a key technology in GSM/LTE co-spectrum scenarios and are confident it will facilitate widespread network deployments and reduce front-end investment,” said ZTE vice president Zhao Xianming.
