The bands are regulated in terms of the allowed operating bandwidth. This is driven largely by the amount of available spectrum in each of the bands. Band allocation is mainly based on the availability of the spectrum for LTE deployment. Also, the UEs will need to support these bands to be able to latch on to the network and, depending on the area of selling, the UEs are enabled for a particular set of LTE bands. For example, for North America, the bands that are reserved for deployment of LTE are bands 2, 4, 5, 7, 8, 10, 12, 13, 14, 17, 18, and 19. For China, the reserved bands are 1, 3, 34, 39, and 40. Bandwidth Options In LTE, as shown in Figure 1-4, there are multiple bandwidth options ranging from 1.4 to 20 MHz. In cases of carrier aggregation, multiple 20 MHz carriers are aggregated to obtain a higher bandwidth.
