Mobile data lte means the mobile 4G network version, which means that the mobile phone is using the 4G network.
LTE is the standard for 4G wireless broadband technology, providing higher network capacity and speed to mobile device users. LTE offers higher peak data transfer rates of up to 100Mbps downlink and 30Mbps uplink. It also offers reduced latency, scalable bandwidth capacity and backward compatibility with existing GSM and UMTS technologies.
#The most significant differences between LTE and its predecessor are changes in frequency and bandwidth usage. There are many 4G LTE bands, and their usage will vary depending on your country and even your specific carrier's technology.
These frequencies are divided into frequency division duplex (FDD) and time division duplex (TDD). FDD spectrum requires paired frequency bands, one for the uplink and one for the downlink. TDD uses a single band on the same frequency for both uplink and downlink, but these are time separated. There are 31 pairs of LTE bands operating between 452 MHz and 3,600 MHz, and another 12 TDD bands operating between 703 MHz and 3,800 MHz. Higher frequencies allow faster transmission in established areas, while lower frequencies provide additional coverage distance but more limited bandwidth. These bands typically provide 10 to 20 MHz of bandwidth for data transmission, although they are also usually divided into smaller 1.4,3 and 5 MHz blocks.

LTE (Long Term Evolution, Long Term Evolution) is formed by 3GPP (The 3rd Generation Partnership Project, the third generation cooperation The long-term evolution of the UMTS (Universal Mobile Telecommunications System) technical standards developed by the 3GPP Partnership Program was formally established and launched at the 3GPP Toronto meeting in December 2004. The LTE system introduces key technologies such as OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multi-Input & Multi-Output, multiple input and multiple output), which significantly increases the spectrum efficiency and data transmission rate (20M bandwidth In the case of 2X2MIMO with 64QAM, the theoretical maximum downlink transmission rate is 201Mbps, which is about 150Mbps after excluding signaling overhead. However, based on actual networking and terminal capacity limitations, it is generally believed that the peak downlink rate is 100Mbps and the uplink rate is 50Mbps), and supports a variety of Bandwidth allocation: 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz, etc., and supports global mainstream 2G/3G frequency bands and some new frequency bands, so spectrum allocation is more flexible, and system capacity and coverage are also significantly improved.
