UE Categories in LTE

 In LTE (Long-Term Evolution) networks, UE categories (or user equipment categories) are used to classify different types of mobile devices based on their capabilities and performance. UE categories till release 13 are shown in below Table 

Each UE category is defined by a set of capabilities and performance parameters, including the maximum data rates that the device is able to support, the type of modulation and coding schemes it is able to use, and the maximum transmits power it is able to use. These capabilities and performance parameters are specified in 3GPP (3rd Generation Partnership Project) standards.

The UE categories are used to determine the maximum data rates that a mobile device is able to achieve in an LTE network, as well as the type of modulation and coding schemes that it is able to use. Higher UE categories correspond to higher maximum data rates and more advanced modulation and coding schemes, while lower UE categories correspond to lower maximum data rates and less advanced modulation and coding schemes.
