What is LTE?Long Term Evolution or LTE is a wireless broadband technology, designed to increase bandwidth capacity and data rates facilitating enhanced mobile applications and better performance. Marketed as 4G, it is considered as the final step from previous technology, thus the name Long Term Evolution. The main advantages with LTE are:
- High throughput
- Low latency
- Plug and play
- Improved end-user experience
- Low operating costs
- Seamless
How does LTE work?LTE operates on the radio frequency and the cellular network to transmit voice and data. The optimal radius of a cell that one base station could supports is up to 100km. It uses pre-coded version of OFDM for uplink and normal OFDM for the downlink. OFDM or Orthogonal Frequency Division Multiplex transmits data in closely spaced carriers to transmit data, enhancing spectrum flexibility and cost-efficiency.
Furthermore, LTE networks has backwards compatibility with the previous technologies like GSM and UMTS that makes low operating cost and wider coverage possible because it could operate without discontinuity where LTE coverage cannot reach. Enabling seamless passing from an LTE base station to the existing deployed networks reflects substantially on better service and cost efficiency.
