Changes in communication standards used in mobile phones
Various wireless devices are used in addition to mobile phones
<Cellular systems up to 4G did not target the wireless communication demands that these other wireless systems covered, but 5G will bring these demands into the 5G wireless system. Plans are being developed with this in mind. In other words, 5G aims to be a standard that goes beyond the “mobile phone network”.
<Even in the latter stage of 4G development, standards for devices other than mobile phones such as LTE-M and NB-IoT, especially for IoT devices that want to reduce power consumption because they do not mind slow communication speeds, were added. I'm here. However, this is just an addition of functions tailored to the specific target of IoT to the mobile phone network. When adding functions, it was necessary to individually deal with mobile phone base station facilities nationwide. In addition, functions were added to meet specific communication needs, and further individualized support was required to meet other needs.
Functions that 5G should satisfy<In the 5G wireless network, a large number of slices with different characteristics are provided according to the purpose, and communication terminals connecting to the wireless network can Select a slice and use it. This mechanism allows 5G to behave as if it were a separate radio system with different characteristics, even though it is one radio network.
