The spectrum is multiplexed over time between both generations of mobile networks, while still using the LTE network for control functions, depending on user demand. Dynamic spectrum sharing (DSS) may be deployed on existing LTE equipment as long as it is compatible with 5G NR. Only the 5G NR terminal needs to be compatible with DSS. [9]
From the latest published version (Rel. 18) of the respective 3GPP technical standard (TS 38.101), [5] the following tables list the specified frequency bands and the channel bandwidths of the 5G NR standard. Note that the NR bands are defined with prefix of "n". When the NR band is overlapping with the 4G LTE band, they share the same band number.
WiMAX and LTE use OFDM. Time-division multiple access (TDMA) provides multiuser access by chopping up the channel into sequential time slices. Each user of the channel takes turns to transmit and receive signals. In reality, only one person is actually using the channel at a specific moment. This is analogous to time-sharing on a large computer ...
The wideband services part of the SMR band was called ESMR (Enhanced SMR). The new band plan allowed Sprint Corporation to deploy CDMA and LTE technologies on this band. The transition to the new band plan is still ongoing as of August 2016 although it's reaching its final stages. [7]

LTE (Long Term Evolution) is commonly marketed as 4G LTE, but it did not initially meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series for LTE Advanced. Given the competitive pressures of WiMAX and its evolution with Advanced new releases, it has become synonymous with 4G. It was first ...
