News: India’s first auction of telecommunications spectrum in five years.
- Telecom spectrum stands for the portion of the electromagnetic wave range that is suitable for communication purposes.
- The different spectrum bands differ in terms of the frequency of these waves.
- Frequency is a measure of the number of times the waves repeat themselves in a second. It is expressed in terms of hertz.
- Hence hertz is a measure of the number of cycles per second, and 1 megahertz stands for 1 million hertz.
- Spectrum bands have different characteristics, and this makes them suitable for different purposes.
- In general, low-frequency transmissions can travel greater distances before losing their integrity, and they can pass through dense objects more easily. However, less data can be transmitted over these radio waves.
- Higher-frequency transmissions carry more data, but are poorer at penetrating obstacles.
- The 700 MHz band, as also 1,800 MHz, 2,100 MHz, and 2,300 MHz bands, are seen playing an important role in the 5G rollout.
- In telecommunications, 5G is the fifth generation technology standard for broadband cellular networks, that promises to provide faster speeds lower latency.
