LInk Up with Cordless Telephones
Before the mobile telephone but long after smoke signals, there were cordless phones, a land line with a cord free handset. Cordless telephone communications are established over radio waves between the telephone’s base and the cordless handset. Communications between the base station and a handset is sometimes limited, with complete signal loss between the different floors of a building not so uncommon.
The base station itself is hooked up to a fixed phone line like standard phones and draws 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. These days one may can even find some cell phone-like features in corldess phones.
While they have certainly advanced, in the beginning when the cordless telephone first appeared on the market the devices were untrustworthy and extremely pricey. 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 two technical innovations resolved the matter of eavesdropping, allowing cordless telephones to take 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, 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 respect make sure to choose DSS technology, at the 2.4 gigahertz frequency at a minimum ( less is less secure while more cuts into battery lifespan ).
And thus we come to the only other major issue: battery power. 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 two concerns, a cordless telephone’s other characteristics are simply matters of personal taste.
