How does a cordless phone work?

You would be forgiven for believing that mobile phones, and particularly smartphones, had rendered traditional home phones obsolete but in actual fact cordless telephones are still frequently utilized in British households.
The landline phone has been around for decades now and while many have done away with the traditional corded or cordless phones, others can’t be with them. The ability to remain connected to the external world even when you don’t have a cellular signal is a blessing for many — especially those who have elderly relatives who need to remain in contact.
So what makes home phones, and especially the cordless selection, so popular? Let’s have a look:
How do cordless home phones operate?
Put simply, cordless phones use radio frequency to connect with the base unit which, in turn, is linked to the mains and a landline phone connection.
The bottom unit functions to control the battery in the phone when not in use and, in some cases, also has the ability to capture answerphone messages when you are out of the house and unable to receive a call

The most important benefit of a cordless telephone is the capacity to make and receive calls from anywhere in the property. Provided that the bottom unit remains within range users may walk around the house and the garden when the signal is sufficiently powerful, instead of needing to remain near the bottom unit as you want a standard corded landline phone.
Just how long do cordless phone batteries last?
Based on the make and version of your landline phone the battery life can vary significantly. Initially every cordless phone is fitted with rechargeable batteries that get their power from the base unit, but with age the battery lifetime will inevitably start to diminish but they can be replaced quickly and easily using a fresh pair of batteries.
What else could I do using a cordless telephone?
Along with having the ability to walk around the house when on the telephone, and to make and receive calls even when your smartphone does not have any signal; cordless home phones also have the capacity to capture messages while you’re outside.
Some have a purpose called annoyance call blocking so you could block certain numbers from calling times of day when you truly don’t need to be bothered; or you could even block them completely to prevent them from pestering you.
