3.3 Base Stations: From Cell Towers to Small Cells
The type of base station used to transmit signals is another key difference between 4G and 5G.
- 4G Base Stations: Utilize traditional cell towers to transmit signals.
- 5G Base Stations: Employ small-cell technology, particularly for higher-frequency spectrums like mmWave. 5G also uses cell towers for its lower-frequency spectrums.
Small cells are compact base stations, roughly the size of pizza boxes, deployed in multiple locations to provide localized coverage. The use of small cells is necessary due to the shorter range and weaker signal strength of mmWave frequencies.
3.4 OFDM Encoding: Enhancing Data Throughput
Orthogonal Frequency-Division Multiplexing (OFDM) is a technique used to split a wireless signal into multiple, narrower frequency channels, called subcarriers, within the same bandwidth to avoid interference.
- 4G LTE Channels: Typically use 1.4 MHz to 20 MHz channels.
- 5G Channels: Use 100 MHz to 800 MHz channels when using mmWave.
Each subcarrier can carry its own piece of the total data, which improves data throughput and boosts download speeds for both 4G and 5G.
