Fact #1. Landlines are still important. Many people use them to keep in contact with old friends and relatives. But they also avoid problematic mobile service networks. Sporting events, natural disasters, and more can interfere with those networks. In the recent past, Hurricane Sandy and the Boston Marathon have shown that. This happens because of how cellular service is distributed. Avoiding those networks means you can hear from people quickly. It also helps lower the bandwidth use for others.
Fact #2. Portable phones were invented in the 1960s. A jazz musician named Teri Pall is the first known creator. Her idea resembled walkie talkies more than contemporary technology. It was hard for her to act on that invention. This is partially due to laws. The phones only worked up to two miles. They also interfered with passing aircrafts. She ended up selling the idea to a manufacturer.
Fact #3. The environment is important. Most home phones will not need many features. Caller ID and call blocking for telemarketers should be considered. But this is one place where you can privilege design. Office phones are a different matter. They should be chosen according to needs. A good speaker is important for conference rooms. The ability to forward calls or page numbers is needed for administrative tasks. Smartphone integration is useful for employees who are always on the go.
Fact #4. It took a long time for standards to develop. Most cordless phones use a standard called DECT. This emerged between 1988 and 1992. It initially spread in Europe. Then it went everywhere. The contemporary technology had existed since 1977. This slow innovation didn't help them against the rise of cellular phones.
Fact #5. They replace the cord with radio waves. Like other landlines, the dock is attached directly to the phone jack. The only real difference is that they cut the cord. This is possible because of the transmission of radio waves.
