Telecom Lead @ Mobile World Congress: Orange, Ericsson and Qualcomm have tested L-band to enhance mobile broadband capacity and user experience.
On February 21, Orange’s network in Toulouse, France, showcased the use of supplemental downlink technology on a mobile network.
Recently, the CEPT (European Conference of Postal and Telecommunications Administration) decided to harmonize use of the L-band (1452-1492 MHz), reserving it for supplemental downlink technology.

The trial system, which uses L-band frequencies for testing, combines L-band frequencies in the downlink mode with Orange’s 2.1 GHz frequencies to boost downlink capacity.
The trial network uses radio base stations supplied by Ericsson and devices equipped with Qualcomm chipsets.
Supplemental downlink can be used to increase downlink capacity on both 3G and LTE networks. The technology represents a significant step forward in traditional spectrum aggregation systems that are already used for HSPA+ and LTE networks by the 3GPP standardization group.
Supplemental downlink provides significantly enhanced technique for using radio spectrum for wireless networks. Supplemental downlink technology can be used in the L-Band and could also be considered in other frequency bands.
This new technology will allow network operators to manage the ever-increasing demand for data service on wireless networks and provide improved performance for end users.
