Before the mobile telephone but long after smoke signals, there were cordless telephones, a land line with a cordless handheld handset. Cordless telephone communications are conducted via radio waves passed between the base and the handset. Communications between these two parts can be very limited, with a complete loss of signals loss between different floors not an uncommon occurrence.

The base station itself is linked to a fixed telephone line like standard phones, drawing power from a wall outlet. It is this base station that continues to distinguish a cordless telephone from cellphones (which require no base station), regardless of the much increased technology of cordless phone units. These days one may can even find some cell phone-like features in corldess phones.

While they have certainly come a long way, in the beginning when cordless telephones first appeared on the market the devices were unreliable and rather expensive. Not only was the operational range rather limited with poor quality sound, but there was no real security or privacy because signals could be easily intercepted by other cordless telephones in the area due to the limited range of channels available. It took about 10 and a half years so that cordless telephones can become familiar household items, with the opening up of the frequency range to nine hundred megahertz heralding the arrival of DSS technology.

These 2 technical inventions took care of eavesdropping fears and cordless telephones took off as favored products. Though cellular telephones are pervasive and here for good, many still keep landlines in their houses for a number of reasons, and cordless telephones remain a viable market, with new models introduced fairly frequently. When selecting a cordless telephone, it is important to keep in mind security issues, for these phones are really just radio transmitters and thus susceptible to eavesdropping, though that does require a reasonably high level of technical know-how nowadays to do so successfully. In this regard, be certain to choose DSS technology, at the 2.4 gigahertz frequency at a minimum (any less impinges on security while any more cuts into battery power).

This brings us to the only other major issue: battery lifespan. Avoid nickel-cadium if at all possible; they will exhibit a so-called memory effect unless they are fully drained before recharging. Apart from these two issues, the rest of a cordless telephone’s features are completely up to personal taste.
