FlexWave™ Base Station System
IP-Based RAN for Indoor/Outdoor Coverage and Capacity
The FlexWave™ Base Station System (BSS) is a complete base station system providing converged
in-building and outdoor GSM, GPRS and EDGE coverage and capacity. It includes the FlexWave
nanoBTS™ and the FlexWave microBTS together with a common base station controller and
common operation management software needed to integrate with existing mobile networks.
Spec Sheet
Taking advantage of the more than 2 billion GSM handsets in use globally together with existing
IP-based broadband infrastructure for backhaul, the FlexWave BSS enables operators to provide
cost-effective tailored capacity and coverage for target customers and deliver excellent return on
investment.
Features:
• Smallest fully functional GSM/EDGE picocell
BTS in the industry
• Fully sealed, maintenance free microBTS for
outdoor applications
• IP-based backhaul reduces costs
• Available for 900, 1800 and 1900MHz
bands
• Compliant with GSM specifications
• Integrates with existing TDM-based or
softswitch MSC
• Alarm management integration
• Single Ethernet connection to BTS
Applications:
• Enterprise in-building premise coverage
• Enterprise indoor/outdoor campus coverage
• Stadiums, subways, tunnels
• Outdoor macro network hole fill (coverage)
• Outdoor macro network hot spot (capacity)
• Rural areas/isolated villages

System Architecture
The FlexWave nanoBTS and microBTS units present a standard Um 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.
