Ericsson GSM Radio Access Network

    GSM offers unique advantages in terms of coverage, subscribers, operational cost, device cost, roaming and M2M application support.

    More than 85% of the world’s population is covered by a GSM network. There are around four billion GSM only subscriptions and 80% of M2M devices are GSM only.

    Voice and data increase and the GSM standard is continuously evolving.

    Thin Layer GSM is Ericsson’s approach to optimizing and evolving GSM for current and future demands.

    The concept focuses on five important aspects where operator’s network needs to be 'THIN' or more efficient:

    • Spectrum
    • Hardware
    • Power consumption
    • Competence
    • OPEX

    Ericsson is the technology leader in GSM and has the most widely deployed products. There are more than 300 customers in 170 countries who have deployed more than 13 000 BSCs and 1.5 million RBS sites across all corners of the world. More than 45 percent of the GSM traffic worldwide relies on Ericsson GSM RAN networks.


    Ericsson’s Thin Layer GSM is focusing on three areas: 

    • Network Efficiency for maximum network resource utilization of spectrum, energy and hardware
    • No Unique HW for a fully integrated multi-standard RAN
    • Automation for OPEX elimination by operational efficiency and simplicity

    Main values

    Ericsson Thin Layer GSM offers superior performance with minimum resources and lowest OPEX.

    GSM Network Efficiency features ensure that network resources are used to the full. The key RAN resources are spectrum, hardware and energy. Spectrum efficiency features significantly increase voice and data usage in a given spectrum, up to 10 times of data capacity and 3 times of voice capacity can be achieved with less than half spectrum. These help operators re-farm spectrum to WCDMA/LTE. Energy efficiency features can reduce energy consumption by 30%. Hardware efficiency is achieved by both compact new hardware, e.g one Evo 8200 BSC magazine is the equivalent of 29 old BSC cabinets and also SW features that ensure efficient use of hardware, like VAMOS.

    Ericsson’s Multi-standard RBS 6000 and Evo Controller 8000 have been widely deployed and Multi-standard mixed mode becomes normal mode of operation. It improves further efficiency by deploying common transport and network management. Multi standard HW also means that spare part handling is greatly simplified. The newly introduced Ericsson Radio System represents a generational shift and delivers operators needed flexibility and agility. With LTE FDD&TDD, WCDMA and GSM on one hardware & software architecture, operators can better manage the complexities of network with one O&M system for all standards and have full flexibility to adapt to technology shifts.

    Automation is the area that Ericsson differ the most from competition. Increased automation of GSM improves operational efficiency and simplicity to reduce expenses. The goal is to have GSM completely automated with minimum manual intervention. Thin Layer GSM encompasses a number of innovative and cost-saving automation features including: Automatic Frequency Planning, Automatic Neighbor Planning, etc.


    Ericsson largest GSM installed base, and best performance in GSM field. We have best expertise and knowledge, proven competitive advantages in many key features implementation such as VAMOS, AFLP, etc. Ericsson can provide the best capacity and performance owing to our advanced radio access network portfolio as well as Global Service expertise.

    Ericsson is committed to continuing to invest in GSM adapted to market changes and lift it to new multi-standard platforms with same hardware and software architecture.
