6. Company confidential 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. Selling Managed CPRI Services For Other Carriers
