Opinion: The Politics of SA vs NSA 5G & 4G Speeds

Download to read offline

Zahid Ghadialy, Principal Analyst and Consultant discusses the operator dilemma of standalone (SA) vs non-standalone (NSA) 5G deployment, frequency refarming and why 4G speeds will start reducing once SA 5G starts to be deployed.

  17. 17. Summary ©3G4G • NSA 5G can provide good speeds (eMBB & FWA) • SA 5G on the other hand will provide a ‘real 5G’ experience • SA 5G needs a lot of spectrum to provide ‘real 5G’ experience, mainly in FR1 or sub-7.125 GHz spectrum • The best option is for an operator to have lots of new 5G spectrum, in coverage, capacity & high-throughput layer • But some operators will choose to re-rafarm 2G/3G spectrum, leading to switch off for some 2G/3G networks • Some operators may also choose to re-farm 4G spectrum, leading to decrease in 4G speeds, which will work in favour of 5G as well • This is just an opinion, every operator will have a different strategy and approach.
