Parallel Wireless, a low cost cellular deployment solutions provider, has announced the addition of 2G capabilities to its end-to-end cellular network technology. This solution 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. This will benefit the 40% of the emerging markets who will still use 2G in 2020 (according to GSMA), as well as developed markets reframing 2G spectrum for use in NB-IoT.
The solution utilizes two main components from Parallel Wireless:
- HetNet Gateway (HNG), the industry's only 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), world's 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 accesses simultaneously and delivers the highest RF output to cover the furthest distance for roughly half the price.
With the intelligence of the HetNet Gateway and the flexibility of CWS, this innovative solution delivers the following benefits to global operators:
- Cost-Effective Network Upgradability via Software-Defined Radio (SDR) Functionality: 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.
- Improved End-User Experience: Since all traffic, licensed or unlicensed, is orchestrated by HetNet Gateway's virtualized real-time 2G/3G/4G SON, this solution allows end-users to switch between cellular and Wi-Fi technologies automatically without impacting their experience.
- Architectural and Operational Simplification: Through HNG's Network Function Elimination (NFE) approach, operators can combine 2G, 3G, 4G gateway functionalities on one platform to simplify deployment and maintenance of any G networks. Real-time SON on HetNet Gateway automates ongoing maintenance via self-optimization capabilities.
- Lowest TCO on the Market: Easy installation and the ability to run 2G/3G/4G on one solution along with flexible in-band relay/meshing backhaul reduces operators' CAPEX. Lowest power consumption and network automation reduces OPEX, so operators can increase profitability throughout the entire network lifecycle.
