Ericsson GSM Radio Access Network

GSM will co-exist with other radio technologies and continue to play a vital role beyond 2020 given its advantages in coverage, number of subscribers, low-cost terminals, roaming and M2M. Operator needs a proactive approach when planning the evolution for GSM network, preparing the network at any capacity level while saving cost and increasing revenue by being as efficient as possible.

Ericsson Thin layer GSM focuses on five important aspects that operator’s network needs to be THIN or more efficient. Those 5 aspects are spectrum, hardware, power consumption, competence and OPEX. The Ericson Thin Layer GSM makes it possible to combine superior performance with maximum resource efficiency and minimum OPEX.


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.
