HUBER+SUHNER has launched the new product family of Smart DC Kits. These new innovative products establish DC powering for Remote Radio Heads (RRH) of mobile communication base stations in specific scenarios reusing redundant coaxial feeders that have been decommissioned.

In recent network upgrades, conventional cell sites using corrugated cables are often converted into remote radio systems. The installed corrugated cables are decommissioned, cut at both ends and re-used as supply lines for the RRHs. The inner and outer conductor of a corrugated cable are used for the power supply. The special Power Smart DC adapter is fitted at both ends of the corrugated cable, guaranteeing secure and reliable contacts.

Cost and time saving

The Smart DC Kits development is the result of technical progress, new standardized RRH BTS equipment of the OEMs and especially the accompanying effect of saving tremendous amounts of electrical power. The latter has developed to a key expense factor for the operators after all the network expansions driven by the unbelievable success of mobile communications. Complete swaps make the old equipment redundant resulting in dismantling it. This will be part of the swapping costs eventually. Part of it can be saved for the corrugated feeder cables and even be turned into additional cost and time benefits by re-using of these old feeders as power supply cables.

Unique competitive situation

The idea of re-using the corrugated cables both for power supply and protecting the FO feed has been established with a worldwide acting operator. The solution has been implemented as “Best Practice” under the term FiPro (Fibre and Power to the roof) within the organization. Following a very professional approach HUBER+SUHNER has designed high current capacity Smart DC Kits superior to the competition. They meet even the highest requirements of RRH powering.
