Small Cell, Carrrier Wi-Fi and wireless backhaul: BelAir2100 LTE/3G/Wi-Fi Metrocell

Smartphone and tablet adoption has driven two key trends that directly impact both the mobile carrier's business and their network architecture.  First, mobile data traffic growth rates are outstripping associated revenue while voice revenues continue their decline.  Second, Wi-Fi popularity continues to increase, with Wi-Fi enabled devices the norm and Wi-Fi only devices increasingly common.

These trends have prompted mobile carriers to look to both outdoor small cell architectures (known as metro femto, metro picocell, or simply, metrocell) and Wi-Fi to cost-effectively augment their traditional macrocell networks in high traffic areas, prone to mobile data congestion. The BelAir2100 LTE/3G/Wi-Fi Metrocell brings together LTE/3G licensed band small cell and dual 802.11n radios, plus integrated wireless backhaul options in one robust, compact base station that’s fast and easy to deploy.

By combining licensed bands and Wi-Fi, the BelAir2100 Metrocell ups the capacity in high traffic areas to improve the user experience, while also enabling carriers to stay connected to any subscribers using Wi-Fi-only devices. Integrated wireless backhaul options minimize wired egress points, reducing both the time and cost (installed CapEx and OpEx) associated with large-scale small cell deployments. This also negates the requirement for “second box” small cell backhaul solutions.

BelAir2100 Metrocell supports multiple LTE/3G licensed band access with a modular architecture that can even accommodate radios from traditional macro/RAN domain suppliers. This flexibility enables mobile carriers to deploy different BelAir2100 Metrocell variants on a regional basis, consistent with their geographic domain vendor strategy, reducing interoperability issues and easing integration for a faster, more-cost effective deployment.

BelAir2100 Metrocell reflects BelAir Networks unique track record of deploying carrier-grade licensed and unlicensed large-scale small cell networks for Tier One carriers. In addition to supporting the latest Hotspot 2.0 (including 802.11u) standards for seamless secure roaming, the BelAir2100 Metrocell goes beyond standards to deliver carrier-grade networking capabilities, including:

  • Proven integration and interoperability with multiple carrier core networks
  • Edge-based policy enforcement interfacing with carrier’s policy management system
  • Edge-based security and support for carrier-grade legal intercept
  • Scalable management supporting up to 100,000 metrocells in a single network
  • Support for multiple tunnelling protocols, enabling full mobility across networks

BelAir Networks robust outdoor gear features an industry-leading mean-time between failure (MTBF) of more than 50 years, carrier-tested and proven in even the harshest climates and most demanding environments. This carrier-grade level of dependability far surpasses traditional enterprise technologies to ensure trouble-free operation, reduced OpEx and a great user experience. BelAir2100 Metrocell also features an all IP backhaul and is designed to mitigate interference and enable full RF interoperability between the licensed band and Wi-Fi access radios, as well as between the metrocell and the macro network.
