To start operations, radio frequency spectrum (RF) is needed, which allows the transmission of all triple play services bi-directionally (downstream and upstream) from the K3 base station antenna to the end user and from the end user back to K3 base station again.
K3 Lastmile solution can be designed to operate on any frequency spectrum levels between 2 and 42 GHz. It can use all major frequency bands already allocated for fixed wireless around the world. Simply put, K3’s solution is able to operate on any spectrum between 2 and 42 GHz as long as the bandwidth required is available on that spectrum.
Two frequency bands are required, one for downstream and one for upstream. Optimum frequency bandwidth for downstream is between 200-500 MHz and between 75-400 MHz for upstream with minimum 200 MHz (1 GHz preferable) bandwidth space between the two of them. The system can utilize even up to 2 x 500 MHz of frequency bandwidth in downstream and up to 500 MHz of frequency bandwidth in upstream.
