An Ultimate Guide to LTE specifications

1. An Ultimate Guide to LTE specifications In telecommunications, LTE stands for Long Term Evolution. It can be defined as a standard for wireless broadband communication for mobile phones as well as data terminals based on GSM and UTMS technologies. It helps in increasing the capacity as well as speed using a different radio interface along with core network improvements. The standard of LTE is developed by the 3rd Generation Partnership Project (3GPP). It is specified in its Release 8 document series along with a few improvements mentioned in Release 9. Long-Term Evolution is the upgrade path for carriers along with GSM/UTMS networks as well as CDMS2000 networks. Different types of LTE frequencies and bands are used in different countries that indicate multi-band phones are able to use LTE in all countries where it is supported. LTE comes with both 4G LTE and Advanced 4G. However, it does not meet the technical criteria of a 4G wireless service. Long-Term Evolution is generally known as 3.95G. It represents a major advance in cellular technology. In simple words, it is designed to meet the needs for high speed data, and media transport along with high- capacity voice support into the next decade.

2. LTE comes with all features to meet the needs of next-generation mobile networks. It allows operators to offer better performance, mass-market phone broadband services, via a combination of high bit data rates, and system throughput in the uplink as well as downlink along with low latency. Hence, the instantaneous downlink data rate is 100 Mbps in a 200 MHz downlink spectrum. Talking about uplink, the data rate is 50 Mbps in a 200 MHz uplink spectrum. LTE is IP-optimized that comes with a scalable bandwidth of 20 MHz, 15 MHz, 10 MHz, and less than 5 MHz. The ideal size for a cell is 5 km. However, it can meet a performance with 30 Km, and an acceptable performance up to 100 km. This performance can reach up to 200 active users per cell, for example, 200 active data clients. In addition, it can be optimized for low mobility, but can support higher speeds. Additional LTE specifications are that the latency in the user plane is less than 5 ms and, in the control plane, is 50 ms. LTE infrastructure is created to deploy and operate, through flexible technology that can deploy in several frequency bands. It also comes with scalable bandwidths that support both FDD paired and TDD unpaired spectrum.
