Though most small cells are expected to be fed using fiber optic cable, running fiber isn't always practical. Reuse of the frequencies used by a small cell to communicate with users (“access”) for communication between the small cell and the network (“backhaul”) will be part of the 3GPP's 5G standards.

5G-Advanced (also known as 5.5G or 5G-A) is an evolutionary upgrade to 5G technology, defined under the 3GPP Release 18 standard. It serves as a transitional phase between 5G and future 6G networks, focusing on performance optimization, enhanced spectral efficiency, energy efficiency, and expanded functionality.
Radio waves are used to transfer signals to and from the cell phone. Modern mobile phone networks use cells because radio frequencies are a limited, shared resource. Cell-sites and handsets change frequency under computer control and use low power transmitters so that the usually limited number of radio frequencies can be simultaneously used by ...
In the past, 4G networking had to rely on large cell towers in order to transmit signals over large distances. With the introduction of 5G networking, it is imperative that small cell stations are used because the MM wave spectrum, which is the specific type of band used in 5G services, strictly travels over short distances.
The main benefits for an end user are the following: "5 bar" coverage when there is no existing signal or poor coverage; Higher mobile data capacity, which is important if the end-user makes use of mobile data on their mobile phone (may not be relevant to a large number of subscribers who instead use WiFi where femtocell is located)

Cell Broadcast messaging was first demonstrated in Paris in 1997. Some mobile operators used Cell Broadcast for communicating the area code of the antenna cell to the mobile user (via channel 050), [5] for nationwide or citywide alerting, weather reports, mass messaging, location-based news, etc. Cell broadcast has been widely deployed since 2008 by major Asian, US, Canadian, South American ...
