I wonder if like the 3G and the 4G rollout in most countries, the first batch of deployments will use the higher frequencies for the new technology keeping the lower frequencies for the legacy technology to ensure everyone retains access to the exisiting coverage while giving some people access to some coverage using the new tech. Then as user adoption of the new tech approaches a certain point the lower frequencies are reallocated to the new technologies when the risk of reducing coverage for users of the old tech is not significant issue anymore. I’ve seen this occur with 2G to 3G (3G started with deployments only at 2100 MHz but is now mainly deployed at 900 MHz replacing the previous 2G services in that band) and 3G to 4G (4G initially mostly in 1800 MHz but many deployments now are in 700 MHz reframed from TV and 900 MHZ reframed from 2G/3G).
