What is a Cordless Telephone?

History of Cordless Telephone
The history of cordless telephone began in the late 1970s with simple analog technology operating at low frequencies of around 27 to 49 MHz.
In the 1980s and 1990s, the technology began to improve with the use of higher frequencies, such as 900 MHz, which offered greater coverage and better voice quality.
In the late 1990s and early 2000s, cordless telephone began to switch to 2.4 GHz and 5.8 GHz frequencies, bringing improvements in voice quality and reduced interference.
A major development came with the introduction of DECT (Digital Enhanced Cordless Telecommunications) as the modern cordless telephone standard.
DECT technology, which uses the 1.9 GHz frequency, delivers crystal clear voice quality, and security through digital encryption, power efficiency, and greater coverage, making it the top choice for cordless communication in homes and offices.
Until now, DECT has been the mainstay of cordless telephone technology in many countries, including Indonesia, where its use is regulated so as not to interfere with other frequencies.
