=== Small Cell / Microcell === | === Small Cell / Microcell === | ||
A small cell is a radio access point with low radio frequency (RF) power output, footprint and range. It is operator-controlled, and can be deployed indoors or outdoors, and in licensed, shared or unlicensed spectrum. | A small cell is a radio access point with low radio frequency (RF) power output, footprint and range.

This should not be confused with the "MicroCell" branded Femtocell that AT&T used to have.<br> | |||
==== Outdoor Microcell ==== | |||
AT&T has a consistent cell numbering scheme for outdoor small cells. Multiple microcells may share one eNB.<br> | |||

AT&T's 5G Standalone network is not available for consumer use yet. Note that it ''is'' still possible to map these networks on some devices via band locking. For best results, try locking n5 or n77 using a '''Verizon'''-based SIM card which may actively avoid locking on to Verizon's own 5G SA network. | AT&T's 5G Standalone network is not available for consumer use yet.
