Evolution of connectivity
Before diving deeper into LTE, it’s crucial to understand the journey of cellular connectivity. Starting from the 1G era of simple voice communication, we moved to the 2G era that introduced digital communication and text messaging. The 3G era brought us mobile internet, and now, we’re in the 4G LTE and 5G era, characterised by high-speed data transfer, improved reliability, and enhanced capabilities.
How does LTE work?
LTE utilises OFDMA or Orthogonal Frequency Division Multiple Access to provide high-speed data services over the airwaves. LTE works by assigning a channel to each user that has access to the network. These channels are then divided into sub-carriers, which are grouped together in resource blocks.
The role of antennas
In an LTE network, antennas play a critical role. These devices capture and transmit signals between your device and the cellular network, enabling data transmission.
Spectrum bands in LTE
LTE operates across a variety of spectrum bands, each offering different characteristics. Lower frequency bands provide a wider coverage area but slower speeds, while higher frequency bands offer faster speeds but over shorter distances.
Data transmission in LTE
LTE technology uses an advanced system for data transmission known as OFDMA (Orthogonal Frequency Division Multiple Access). This system allows for high-speed data transmission with minimal latency, providing users with a seamless internet experience.
