Globally 2,5 million telecom tower sites were built for GSM voice with 3 sector 18 dBi antennas for > -104 dBm indoor.
To deliver LTE full data rates and full spectrum efficiency requires -72 dBm, or 32 dB higher signal. This is only possible with phased array antennas and a cascade of total site improvements including very few but stronger and higher towers with capacity for 18 sectors and all bands and operators incl. MIMO8.
Thereby obtaining dramatic techno-economic KPI’s to deliver >20 Mbs to all countryside indoor customers. With capacity of 100 GB/mnth at site costs < $1,00 , being lower than in most urban std base stations.
Torbjörn Johnson is a mobile base station pioneer and has designed hundreds of unique radio components, TRXes, Filters, Amplifiers, Antennas and total site system solutions, in several founded Radio Design companies.
