Nokia Siemens Networks, MediaTek collaborate for improved GSM spectral efficiency
Innovative OSC feature enhanced with VAMOS mobile device support
Nokia Siemens Networks has successfully completed testing of Orthogonal Sub-Channel (OSC) support for Voice services over Adaptive Multi-user channels on One Slot (VAMOS) handsets with the mobile chipsets provided by MediaTek. For operators, the benefit is that they can further reduce the spectrum capacity required for GSM.
Orthogonal Sub-Channel makes VAMOS GSM handsets, which boost receiver capacity, work even harder. Part of Nokia Siemens Networks’ Liquid Radio Software Suite, OSC is an innovative GSM feature that has been commercially available since 2011. It supports up to four devices in one radio timeslot, providing up to double voice capacity in GSM. Nokia Siemens Networks is the inventor of OSC and the established market leader in GSM spectral efficiency features. The OSC feature is currently in commercial use in networks serving more than 500 million users.
By enhancing OSC with support for VAMOS handsets, an average capacity increase of 5% can be provided, helping operators further reduce the capacity required for GSM and dedicate more network resources to WCDMA and LTE when they are re-farming spectrum. Successful compatibility testing with VAMOS capable chipsets is a major milestone in this development.
“It has been a pleasure to work with Nokia Siemens Networks, which has a long record of driving innovation in this area. Enhanced VAMOS chipsets have been available since December 2012, which was fully in line with Nokia Siemens Networks’ expectations,” said Jeffrey Ju, general manager of the Smartphone Business Unit at MediaTek. “VAMOS functionality has now become a baseline feature of MediaTek powered handsets.”
“Collaboration with MediaTek to implement OSC enhancements for VAMOS-capable devices puts us in a position to offer even better GSM spectral efficiency to our customers,” said Kimmo Virkki, head of GSM product management at Nokia Siemens Networks. “We will continue innovating in this area.”
Nokia Siemens Networks has over 70 OSC customer references today. Nokia Siemens Networks’ OSC support for VAMOS handsets has been available since the end of 2012 and is compliant with 3GPP GERAN release 9.
