Mobile Backhaul/Fronthaul

The Radio Access Network (RAN) evolution is one that is driven both by technology advancement and economics. The increased use of the mobile network to deliver content - data and video in particular - is putting a strain on the existing copper-based telco infrastructure.

The need for more bandwidth means the need for multiple radio frequencies at any particular site in turn requiring multiple additional remote radio heads (RRHs). At the same time, the competitive marketplace for mobile services is putting tremendous pressure on pricing meaning that the cost of the underlying infrastructure must be kept to a minimum.

To address this problem and to prepare themselves for the coming wave of 5G deployment, forward-thinking network operators are now switching to fiber-based architectures that take fiber all the way from the mobile switching center to the antenna base station. With a fiber-based architecture, mobile operators have the flexibility to use low cost passive backhaul solutions.

Operators can then complement these passive backhaul networks with a CPRI-based fronthaul solution to provide greater bandwidth to the RRHs and optimize the mobile access network architecture. Though fronthaul was originally intended as the next frontier in 3G/4G mobile network architecture, its true potential won’t be fully realized until 5G begins to take hold. However, deploying a fronthaul architecture now gives mobile operators a head start on this transition and can help simplify true 5G rollouts when they do happen.

EKINOPS provides both active backhaul solutions as well as CPRI-based fronthaul solutions, all from a single C200HC or C200HC-ETR chassis. EKINOPS' PM LMA-D10 CPRI solution supports ten client aggregation ports that can combine eight CPRI ports and two Ethernet-based SyncE ports, as well as two line ports. Using CPRI aggregation means fewer fibers are required to deliver high bandwidth efficiency and flexible multiplexing capability.

EKINOPS also provides cost-efficient, 1RU based passive solutions with our temperature hardened CM OM and CM OADM multiplexers and OADMs for both CWDM and DWDM channels making possible a broad range of multiplexing schemes in single or dual fiber configurations.
