System Architecture

The FlexWave nanoBTS and microBTS units present a standard U

air interface to the handset, while the

FlexWave Base Station Controller (BSC) interfaces with existing standard TDM-based MSC and SGSN

core network elements. Furthermore, with its PoE capability, the FlexWave microBTS can be combined

with WiMAX backhaul units for quick deployment in many areas. The indoor FlexWave nanoBTS units

and the outdoor FlexWave microBTS share a common BSC and Operations and Management Center–

Radio (OMC-R) and can also share a common IP backhaul network. This can result in significant CAPEX

and OPEX savings versus disparate solutions. This common approach also makes it easier for RF planning

engineers to target radio capacity exactly where needed in the network, without having to sacrifice

outdoor coverage and capacity at the expense of providing in-building coverage.

Operational management of the whole system is provided by the FlexWave OMC-R, which supports the

configuration of the system together with performance management and alarm monitoring.

Benefits:

• Increase ARPU via increased customer loyalty

• Create a foundation for fixed mobile convergence to support IMS services

• Reduce CAPEX and OPEX via a single IP backhaul network for all services

• Extend coverage and capacity in hard to reach areas

• Increase network capacity to support bandwidth intensive services (video)

• Provide faster time to service

• Allows simple handoff control between in-building and the wide area cellular coverage

• Provide single management and provisioning interface for indoor and outdoor applications

• Increase coverage and capacity where and when you need it; on demand
