1 Introduction
Indoor wireless coverage is one of the most challenging areas in the wireless industry. Alvarion develops
innovative communications equipment, infrastructure and products – enabling wireless operators and
property owners to deliver high quality indoor wireless services using a Distributed Antenna System
(DAS).
Alvarion developed a unique DAS solution for improving in-building wireless coverage in commercial
buildings such as airports, stadiums, shopping malls, hotels, office buildings and residential areas. Such
locations suffer from wireless coverage problems such as interference, attenuation, and multi-path due
to their height and build. The solution is installed using a hybrid fiber and TV type coaxial cables.
BreezeCELL’s unique flat architecture makes it extremely cost effective.
The solution can also be installed using existing coax cables infrastructure, used to distribute TV signals
within the building. Alvarion believes that utilizing the already installed TV infrastructure is the most
cost effective means of providing these services.
Value proposition
Affordable active Distributed Antenna System
Very low installation cost
Unique MIMO on a single cable solution
Plug and Play - very fast and flexible installation process
Multi-Operator, Multi service
Easy design and fine tuning
Fast ROI
2 The Concept
Indoor wireless coverage is traditionally done via external macro cells. In many cases coverage is
problematic due to interference, attenuation, multi-path and other issues.
BreezeCELL distributes the cellular signal throughout the property over a combination of fiber and 75
ohm coax to active remote units and antennas located throughout the building area.
On the other hand, almost all buildings are equipped with coax cables infrastructure, used to distribute
TV signals within the building. Alvarion's solution can use this existing cabling infrastructure through
unutilized bandwidth on the coax cables to bring wireless services into the indoors environment.
Alvarion's technology enables servicing multiple operators and technologies (i.e GSM, UMTS, CDMA,
WiMAX, iDEN) over the same infrastructure in order to increase the utilization of the cable
infrastructure. BreezeCELL is a forward compatible system and fits current and future protocols (LTE,
etc) and has a unique MIMO solution on a single cable support.
