So as the world starts to emerge from the disease, and as countries ease lockdowns, how are operators rethinking their 5G strategy in the face of even tighter cash constraints?
Two technologies with one spectrum band
One technology gathering momentum is Dynamic Spectrum Sharing (DSS). This game-changing technology essentially allows operators to provide 5G coverage and improved speeds using existing 4G spectrum. This is possible because many of the 4G radios in use in networks today were designed to be ‘5G ready,’ and therefore support both technologies without the need to buy additional spectrum, or re-farm other available bands.
DSS is essentially a software upgrade. When launched, determining which technology needs to be supported by which radio is decided according to the device, service requirements, load levels and amount of buffering required. The network then dynamically and instantly allocates 4G or 5G capacity as needed. Spectrum and network resources are then portioned out to the millisecond, which is the true requirement and measure, for DSS success.
