Enabling innovative approaches for advanced service delivery
T h e C l e a r C h o i c e ®
Enable a more
cost-effective
wireless operation
The business of providing wireless broadband communications
services is a continuous balancing act for wireless network
operators worldwide. On the one hand, operators must invest in
continuously evolving technologies to enable delivery of premium
services to subscribers. At the same time, they must find operating
efficiencies that offset the capital cost of technology investments
required to deliver the high volume, low margin services
subscribers want.
Radio Frequency Systems (RFS) provides complete wireless
infrastructure solutions that enable efficient delivery of advanced
wireless broadband services and a more cost-effective wireless
operation. Based on an unrivaled knowledge of wireless
infrastructure, RFS’ proven portfolio of lightweight, high
performance RF equipment is optimized to provide the best

possible performance, compatibility and cost-effective longevity
for the full range of the most common bands, applications and
emerging technologies, including LTE, CDMA 850, GSM 900 and
1800, PCS 1900, AWS and UMTS 2100.

To ensure lifetime reliability, the corrugated aluminum
outer armor provides more durable, lightweight
protection than polyethylene tubes and at a much
lower cost than cable trays. This armor protects the

protective jacket on each individual cable pair ensures
the inner cables are suitable for outdoor use.
