FlexWave™Universal Radio Head
Long-
Universal Radio Head for Flexible Outdoor Coverage and Capacity
Tri-Band 800/900 and
FlexWave™– ADC’s Next Generation of Wireless Solutions for
Improving Wireless Capacity, Coverage, Flexibility and Customer
Retention
ADC’s FlexWave™ Universal Radio Head (URH) is the most flexible, scalable and complete
solution for addressing coverage and capacity needs for current and emerging wireless
networks. The URH improves wireless network coverage and capacity by extending
services from existing cell sites, to hard-to-reach areas by distributing coverage from a
centralized radio suite.
Utilizing a centralized distributed architecture, service providers are able to recognize
significant CAPEX savings through a shared Base Station Hotel (multiple BTS co-located
together), as well as a shared Remote Radio Transceiver approach. The URH’s flexibility
and scalability offers service providers an optimal solution for multiple applications such
as; a dense urban center, dense suburban area, campus, enterprise buildings, subways
and tunnels. The URH’s distributed architecture and small form factor allows service
providers to cost-effectively increase coverage and capacity in these hard-to-reach areas.
Features and Benefits:

Universal Radio Head for Flexible Outdoor Coverage and Capacity
Overview
With the increasing popularity and reliance on
wireless voice and data services, subscribers
expect to have coverage at anytime, anywhere.
In addition to increased wireless device usage,
wireless service providers implementing 3G
technologies, have recognized a reduction in
coverage patterns within existing coverage
footprints, opening coverage “holes” within the
network. To resolve this issue, it requires service
providers to extend coverage and/or increase
capacity within the non-coverage areas. This has
been traditionally accomplished by adding new
macro cell towers; however, with city centers
becoming more congested and local government
zoning regulations becoming more stringent,
obtaining permits for new macro cell sites is
becoming increasingly difficult. The URH offers
service providers a flexible, small form factor
solution to extend coverage and capacity where
needed, as well as support for the increasing
number of protocols and frequencies available
today and in the future.
Application
The URH uses patented digital-over-fiber
technology to distribute RF to desired locations.
The URH digitizes the entire designated RF band
and digitally transports RF over dark fiber or
millimeter wave (MMW) links and reconstructs
the signal at full bandwidth, regardless of
modulation technology at the remote location.
ADC’s digital RF transport allows RF signals to be
replicated at full dynamic range, independent of
the link length, for improved data throughput.
As service providers migrate to 3G and G4
networks, high data rate broadband services,
networks utilizing a URH backbone will be ready.
The URH offers a flexible architecture to
distribute wireless coverage and capacity. Its
versatility and small form factor allows service
providers to quickly deploy networks in areas
where zoning restrictions often hinder
installation of traditional macro cell towers
and base stations.
Centralization of base station capacity can
also be realized using URH. This allows service
providers to further benefit by reducing
capital expenditures and annual operating
costs.
