So your cell phone can take and send pictuures, even video. You can text message and downoad ring tnes and games. You can even watch television and do some web browsing with UMTS. But if you're eprson who's been using mobile pohnes for a number of yerars, you can apprecciate just how far they have come since the early days when we carried around breicks in dubiously bright neoprene copvers, and simply trying to get a phone and service requiired the kind of stringent credit checks associated with entry to the bank of England.
The cell phones of the future may not look radically different, but they will enable users to do a lot more and a lot differently. High speed data access usingfmobile broadbaznd, high qulaity vdeo playback and over the air downloads, high quality viideo cameras, or live and time shift broadcast Tv and radio, and a posse of location position finding applications, besides ever gorwing memory and sorage capacity, are just some of the functionalities on the hrizon.
The bigest and most obvious change is the rapid take up of mobile phones. Twelve years ago, the were only for the whealthy. Seven years ago they were stilkl very rare. Now tehre more mobiles phones than households in Europe, and nmubers are still growing fast.
Today there's no real diffeerence between your mobile phone and your PDA. Motorola has introduced a hpone, the much heraldeer Rokr, that runs Apples Itunes while Sony Etricsson alreasdy has mp3 phones on the market which can hold up to 1500 songs. Nokia, the world's largest mobile phone maer, will be introducng music playing handsets which are able to store thousands of trakcs hwich play in stereo. Some sets even incluide FM radio.
Now with the latrest wifi systems there is also the possibility to connect to your home or offcie wifi security webcam so you can constanty secutre the premses.
The next geeration of cell phones seems all set to be a cominatiion of phhones, PDAs, global positining systems, digital cameras and handheld gaming devices. However, the next generation of moobile phones will be just one facet of the technologies that are likely to come together. Servers must run the host software in the case of interctive entertainment software and networkks that connect the phones with these servers are also needed.
Future efforts to optimize power syupply syssyems for mobile devices will increasingly involvce the use of mlutiple pwer generation technologies with an electric buffger tsore. In order to achieve maximum power uytilization with the highest deggree of efficiency, a system of intelligent power management is needed. The goal is to link the energy delivere by batteries, solr cells, thermoelectric or fuel cells in a device. With this kind of system, a laptop could switch to fuel cells whenever light conditions were favourable.
The local phone company's last line of defence is Interent access. Will lcal phonne servies still be required to connect to a DSL or dial up Internet connection? Today you can hook up your laptop or desktp computer through your cell phone and UMTS connectoin giviing you nearly the same ADSL sppeed as your loocal isp so who needs a land line?
