RFS Infrastructure Solutions for Remote Radio Head Deployments

Enabling innovative approaches for advanced service delivery

The Clear Choice® 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.

2 Hybrid cabling and Simplify RRH deployments; innovative connection Lower costs solutions

RFS’ portfolio includes hybrid cabling Upgrading technology, reducing operating expenditures (OPEX) and connection solutions that make it and decreasing CO2 emissions at cellular sites are constant challenges easier to streamline operations when for operators around the globe. Distributed base station architectures upgrading or replacing traditional allow operators to address these challenges by installing the RF filter base station configurations with the and power amplifier of a base station next to the antenna on a tower or latest distributed base station rooftop rather than at the tower bottom or a building basement where architectures. old-style macro base stations are typically located, thus creating Remote Radio Heads (RRHs). These solutions are the result of ongoing investments in R&D and a close working But installing RRHs close to antennas requires operators to extend data relationship with customers, which transmission, power and grounding cables to the RRH on the tower or ensure all products are designed to meet rooftop. This can be a costly and complicated effort. the demanding network infrastructure needs of today and the requirements of The RFS portfolio of hybrid cabling and connection products emerging communications standards. simplifies the process and lowers the cost of distributed base station architectures. This complete portfolio includes: The result is lightweight, cost-effective hybrid cabling and connection HYBRIFLEX™, a revolutionary RRH hybrid feeder solutions that make innovative use cabling solution, which combines optical fiber and of materials to reduce tower load DC power in a single corrugated cable and maximize existing infrastructure investments. DC-FIT™, the world’s first DC converter solution, which features innovative new technology that turns existing coaxial feeders into RRH power supplies

F/O-FIT™ for site renovation, an optical cabling solution, which allows the reuse of existing deployed coaxial cable to carry a fiber bundle through the inner conductor tube to transport optical signals to a RRH. INFRASTRUCTURE SOLUTIONS FOR REMOTE RADIO HEAD DEPLOYMENTS RFS
