Mobile Technologies: Then and Now II

Filed under: Cordless Phones

First there were analog mobile cordless phones. However, cordless phones of this type are quite a rare sight nowadays. This was largely due to the emergence of digital cell networks that successfully supplanted analog cordless phones in the market.

Now, instead of telephones that require so much effort in operating and managing them, we have cordless phones with various models able to cater to different consumer needs and whims. Those whose tastes run to the basic and functional may opt for classic cordless phones that pack along a bare minimum of features. There are also the complicated ones, the unwieldy cordless telephones equipped with so many features that it’s a true wonder how all functions were able to fit into one package. The downside though is some of these units seem to have been developed and designed by a team of very accomplished torturers whose goals in life include inducing confusion in the unit’s users.

And of course, whenever users find themselves having more than a bit of difficulty trying to operate and manage the functions of the cordless phone they have at hand, then it almost always means one thing: it’s time to move on to the next one. Trying to work with a digital telephone or cordless phone that requires unnecessary effort involving even the most basic operations does not exactly make for an efficient user experience.

Luckily though, the market cordless phones fusing form and performance have made it into the market as well. Exhibiting commendable flair in fashion as well as function, a number of these cordless telephones introduced a brilliant new age in cordless phone design, development and technology. This is spectacularly exemplified by the run of cordless Skype phones, VoIP DECT phones, Wi Fi phones as well as other kinds of digital telephones already out in the market.

However, as can be expected when there are quite a number of players in the field, complications have inevitably sprung up. This involves the rather disharmonious state between the two incompatible digital standards: GSM and CDMA, making for circumstances that are less than ideal. GSM is the dominant technology well outside the United States while the U.S. depends a great deal on CDMA. Mobile cordless phone networks are entirely incompatible with other networks, and phones operating on CDMA are confined to one vendor. This is precisely the reason why most of us have had to go out and buy new cordless phones each and every time we change carriers—never mind the fact that the cordless phone we have at hand are still capable of working without mishap. It’s almost always the case that most cordless phones work with only one carrier.

Another discernible pickle in the situation is that this network incompatibility is further compounded by carriers that insist on making roaming contracts with each other. What happens, of course, is that users end up paying for the services at a price that’s a bit too rich for their blood. The thought of enjoying affordable costs, thus, have definitely gone by the wayside.

On the other hand, GSM offers support to Subscriber Identity Module (SIM) cards. The SIM cards are confined to networks, rather than to the digital telephones. This is to say then that swapping SIM cards readily makes it possible for users to connect to different networks. For users of CDMA cordless phones, though, the equivalent of the SIM is the Re-Usable Identification Module (R-UIM). While this is not yet being sold anywhere in the US, the e-product has already been introduced in a number of other viable consumer electronics markets around the world.
