Cellular Phones versus Cordless Landline Phones
Posted by at 12:00 AM. Placed in Uncategorized category
Before the mobile telephone but long after smoke signals, there were cordless telephones, a land line with a cord free handheld handset. Cordless telephone communications are conducted via radio waves passed between the base and the handset. Communications between these two (the base station and handset) is sometimes limited, complete signal loss between the different floors of a place would not be so bizarre.
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. 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 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 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 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 regard, be certain to choose DSS technology, at the 2.4 gigahertz frequency at a minimum (less than that is less secure while any more impinges on battery lifespan ).
This brings us to the only other major issue: battery lifespan. Avoid using nickel-cadium if at all possible because such battery types have a 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.
