Mobile Phones And Personal Digital Assistants

Next generation mobile phones, personal digital assistants and ultra mobile PC's:-

Next generation mobile phones and personal digital assistants now have screens capable of displaying streaming audio and video. 3rd Generation phones, 3G / 4G & UMTS (universal mobile telecommunications system), devices were seen as a massive new market for the networks operators.

Next generation phones are becoming more and more like PDA’s, next generation versions of these devices as can be seen within some of the videos within this ebook, should show you that mobile devices and the web along with 3d CG are all taking us into a VR realm, no matter which mobile device you end up connecting to the web with.

Wireless gaming is seen as the next big thing in the handheld market, ID Games have developed a ready-to-go engine, that works with PDA's, GPRS telephones, and desktop PC's. This means that someone sitting in their bedroom playing on a desktop PC, can be playing an online game with someone sitting on a train playing on a GPRS / 3G phone or wirelessly connected PDA. Although nobody has a good working business model for 3rd Generation devices, networks are selling it on a per service basis, the database owners were seen as potential suppliers of such services / content a current example of such services would be the NGage and it's arena system.

Ericsson & Siemens have also unified their efforts to turn the cell phone into a portable gaming platform. These companies are providing the back end API's, to allow the ASP’s providing such services, to charge per usage. The merging of all these platforms and increasing standardisation in the software required to connect to them, was seen as being good news for the developers of the database network, i.e. more standardisation usually means lower development costs. Also see MMS, Microsoft's Windows Mobile and Java ME.

Bandwidth to third generation GSM phones, (Global System for mobile communications) is getting higher all the time. Also the uptake and full implementation of EGDGE and GPRS on mobile systems, means that most next generation platforms are becoming permanently connected to the net. These types of phones are already available and expansion of these services, (see HSCSD), will probably allow some future version of the grid principal to be employed over mobile links. Bandwidth to 3G mobiles is set to rise, Bell Labs has shown that 24Mbps, over mobile links is possible, this is part of the emerging system, which is the HSDPA standard - High Speed Downlink Packet Access. (All part of the new spread spectrum technologies being invented and pushed into the commercial mainstream). Check out 4G's potential bandwidth - up to gigabit per second.

The Japanese have had these types of PDA phones and services for quite some time, in the guise of their i-mode users, along with other such systems. All these new devices and network services simply equates to many new users and networks wanting content. Wireless service providers, are all looking for ways to capitalise on these new systems. This once again, was seen as just another market, for the database owners to tap into. Wifi equipped net appliances such as the Play Station Portable are showing the way to the future for this market sector.

The Universal Mobile Telecommunications System is in constant development, but the future is set to use many different approaches but the most promising will probably use a system called, software defined radio (SDR), this is partly based on technology borrowed from the military. It should in the future, allow mobile phone systems to act more like PC's in their interpretation of any data sent to them, or plucked from the airwaves. The upshot of this type of hardware development, will mean that mobile phones will be capable of software decoding any signal sent to them. This can be likened to installing a plugin onto your PC, allowing it to play a particular movie or sound format, these types of chips are already in development.
