Well the question still stands then. What will happen with the spectrum currently allocated for their CDMA2000 cellphone network ? Will they migrate it towards LTE ? Or will they just kill the cell business all together and put everything in the WiMAX basket ? Questions.. questions..
If the sprint board has any sense left in it, they should migrate towards LTE when time will come and go with the flow if they actually intend to stay afloat.. IMO
CDMA2000 will get phased out, less and less CDMA2000 phones will be sold, advertising will push joe six pack to LTE phones. 4 years before CDMA shut down new phones will stop being sold. 2 years before shut down no phone activations/registrations, only phones currently on will work, nobody can add new CDMA phones to the network. 1 year before shut down people get the letter saying their phones will stop working and a new handset coupon for 1/2 off with a new contract (if contracts still exist in the industry).
Technologically, less and less spectrum will be allocated to CDMA2000, and basically the whole phase out process will be identical to TDMA phase out by ATT/Cingular/GSM carriers/a couple CDMA carriers.
