Small cells are low-powered cellular radio access nodes that operate in licensed and unlicensed spectrum that have a range of 10 meters to a few kilometers. Small cells are critical to 5G networks, as 5G's radio waves can't travel long distances, because of 5G's higher frequencies. [104] [105] [106] [107]
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.
Each cell's coverage area is determined by factors such as the power of the transceiver, the terrain, and the frequency band being used. A cell typically uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed service quality within each cell. [1] [2]
RF Drive testing is a method of measuring and assessing the coverage, capacity and Quality of Service (QoS) of a mobile radio network.. The technique consists of using a motor vehicle containing mobile radio network air interface measurement equipment that can detect and record a wide variety of the physical and virtual parameters of mobile cellular service in a given geographical area.
The performance of each technology is determined by a number of constraints, including the spectral efficiency of the technology, the cell sizes used, and the amount of spectrum available.

The methods of deployment of cellular networks is undetermined. An option is to install a 6G tower at every building. The second option would involve integrating the functions of a 6G tower into devices like smartphones, allowing these devices to create their own cell for other users. The commercial release date is estimated to be 2028~2030. [9]
