Poor Cellular Reception was one of the most common problems in the US prior to 2016. Verizon Wireless came up with the novel idea of FemtoCell
The FemtoCell device acts as a Mobile Network Operator / Cellular Service Provider's Mini Base Station and it connects to the Service Provider's Exchange using the customer's DSL / Cable Broadband Connection.
Thus this could solve the last mile wireless signal reception problems in Homes and SOHO where each FemtoCell could service 8 wireless devices.
NOTE: I keep forgetting what this technology is, hence this post is a note to self.
