SMALL CELL – CPRI SOLUTION

Koby Reshef

Company confidential

• Connect antennas to the base stations or BBUs with reduced fiber resources by factor 8 (or more)

• Manage and monitor the fiber attenuation and CPRI services• Can overcome high attenuation fiber cost effectively (amp)• Provide diagnostic tools for each service running over the fiber

(loopback, PRBS)• Can provide facility protection for the fiber• Potential to sell CPRI link instead of full fiber to other service

providers • Utilizing existing fibers for combining existing 3G services and new

CPRI• Provides the option to manage the CPRI throughput rate by making

the MICRO to MACRO path a non-dark fiber solution.

• Wireless carriers are looking to do small cell sites on light poles, side of buildings, etc… and looking for wholesalers to backhaul that traffic from their antennas to the base stations or BBUs at the closest “regular cell” site or MACRO cell site.

• Wholesalers are looking for a box that is transparent to a CPRI signal, but gives us the option to manage the throughput. Basically a box that will make the MICRO to MACRO path a non-dark fiber solution.
