The French telecoms regulator, Arcep, has given Orange France approval to test the use of frequencies in the L-Band to provide mobile broadband systems with supplemental downlink capacity. The test, scheduled to start in early 2013, will use Ericsson base stations and devices using Qualcomm chipsets to assess the potential of using additional frequencies to boost the capacity of 3G and LTE networks regardless of the country or operator. The companies will be exploring the potential of using additional frequencies to boost capacity of 3G/UMTS and LTE networks regardless of the country or operator. Supplemental downlink can provide a boost in network capacity by exploiting inter-band multi-carrier technology standardized in 3GPP for 3G/UMTS and LTE. Article
