Editing Electromagnetic compatibility (section)

=== Modern era ===

From the 1980s on the explosive growth in [[mobile communication]]s and broadcast media channels put huge pressure on the available airspace. Regulatory authorities began squeezing band allocations closer and closer together, relying on increasingly sophisticated EMC control methods, especially in the digital communications domain, to keep cross-channel interference to acceptable levels. Digital systems are inherently less susceptible than analogue systems, and also offer far easier ways (such as software) to implement highly sophisticated protection and [[error-correction]] measures.

In 1985, the USA released the ISM bands for low-power mobile digital communications, leading to the development of [[Wi-Fi]] and remotely-operated car door keys. This approach relies on the intermittent nature of ISM interference and use of sophisticated error-correction methods to ensure lossless reception during the quiet gaps between any bursts of interference.
