The base unit is central to the functioning of a cordless phone. It connects to both the handset and the socket to your regular phone line. The range of a cordless telephone is proportional to the distance from the base unit.
The quality of the reception from modern day cordless phones is very good with few dropped calls.
In their earliest days, rotary telephones were common and required nothing more than a connection to a landline. Cordless phones require a power source to recharge the batteries in the portable handset. When the handset is not in use its batteries are automatically recharged by the base unit.
Unfortunately there is a limit to the number of times the battery can be recharged before a replacement is required. It is not always easy to find repalacement batteries on older models. In many cases the best solution is to simply purchase a complete new phone system.
Years ago, there was growing concern about the privacy related to using cordless phones. Of particular concern was the chance of baby monitors and other radio devices picking up the calls. Thankfully, the latest phones are much more secure than the older models. Phones that operate at higher frequecies are generally much more secure than those operating below 900mhz.
