Parallel Wireless adds 2G capabilities to 3G/4G end-to-end SDR

November 02, 2017 // By Jean-Pierre Joosting
Parallel Wireless, Inc., has announced the addition of 2G capabilities to their end-to-end cellular network technology. This will bring network virtualization principles (NFV) to 2G/GSM to reduce cost and complexity of rolling out or expanding 2G networks while enabling cost-effective migration to 3G/4G.

With 2G added to the SDR system from Parallel Wireless, 40 percent of emerging markets who will still use 2G in 2020 (according to GSMA) will benefit, as well as developed markets refarming 2G spectrum for use in NB-IoT.

Peter Jarich, VP and Chief Analyst, Global Data said: "There are still many markets around the world where 2G deployments continue and will need to be supported into the future. 2G R&D, however, is not always a priority for every network vendor. Support for 2G is a logical move for Parallel Wireless, building on their 3G/4G deployments and an architecture designed for flexibility. For operators looking to serve emerging markets while investing in future network expansions, the capabilities will be welcomed."

This system utilizes two main components from Parallel Wireless:

  • HetNet Gateway (HNG) – a 3GPP-compliant 2G/3G/4G network orchestrator that virtualizes essential network functionalities on one platform to enable network simplification and automated maintenance. By unifying and orchestrating any G on a software-upgradable platform, HNG also paves the way for 5G;
  • Converged Wireless System (CWS) – the first 2G/3G/4G base station built using commodity silicon combines Baseband Unit (BBU), Remote Radio Head (RRH), edge router, and flexible backhaul in one small form factor. CWS can provide any combination of 2G/3G/4G access simultaneously and delivers the highest RF output to cover the furthest distance for roughly half the price.

With the intelligence of HetNet Gateway and the flexibility of CWS, global operators get the benefits of cost-effective network upgradability via software-defined radio (SDR) functionality. Furthert, by integrating GSM, UMTS, and LTE on the same form factor, operators can provide 2G access and seamlessly migrate to 3G/4G capabilities at their own pace and budget with a software upgrade from HNG, without replacing the equipment onsite.
