Before the mobile telephone but long after smoke signals, there were cordless telephone systems, a land line with a cord free 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 differentiate between a cordless telephone and cell phones (which do not need a base station), no matter the great technological increases of cordless telephone units. Nowadays you can even find some cell phone-like features in corldess house phones.

While they have certainly come a long way, when cordless telephones were introduced to the market the devices were not very reliable and rather expensive. Not only was the operational range intensely limited and sound quality deplorable, but there had been just about no security or privacy because signals may be simply intercepted by other cordless telephones in the area thanks to the absence of available channels. It took about 10 and a half years for cordless telephones to become familiar household items, thanks to the opening up of the frequency range to 9 hundred megahertz with 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, plenty still keep landlines in their houses for a number of reasons, and cordless telephones remain a workable market, with new models introduced reasonably frequently. When selecting a cordless telephone, the very first thing to bear in mind is security:these phones are really just radio transmitters and thus subject to eavesdropping, though nowadays requiring a reasonably high level of technical proficiency to do so successfully. In this respect make sure 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 sole other major issue : battery life-span. Avoid nickel-cadium if at all possible ; they depend on a memory effect whereby such batteries must be fully drained before recharging. Aside from these 2 matters, the remainder of a cordless telephone’s features are completely up to personal taste.
