The 3GPP B7 (2600 MHz) LTE band is the third most popular band used by public mobile operators for LTE network deployments, and is typically deployed due to the wide availability of spectrum and its short range permits deployment dense coverage for maximum capacity.
Mobile network operators have flexibility to deploy LTE using band 7 as a single band or as part of a multi-band network. LTE-A or LTE-Advanced Pro technologies can be deployed using carrier aggregation to combine various bandwidths of band 7 with other carriers.
Propagation of the 2.6 GHz frequency band is adequate for outdoor usage in all environment types, and indoor usage in dense urban environments. B7 carriers are also commonly observed as an ancillary band in many carrier aggregation deployments.
