Cell phones. Look how far they have come. In just a few years, people can now take picture, send text messages, check their email, surf the net, and navigate the streets with the GPS capabilities.
So what is in store for the future?
In the next few years, cell phone networks will move data at several megabits per second, and will coexist with WiMax, Wi-Fi, and, for TV, DVB-H or MediaFLO. IMS will let them work together.
Expect not just high resolutions (8 megapixels and beyond), but also the same image-processing capabilities found in current digital still and video cameras.
But before phones can really compete with your desktop computer or laptop, they’ll have to get beyond at least one barrier: their tiny screens. One solution to those cramped displays is under development by Redmond, Wash.-based Microvision (nasdaq: MVIS – news – people ). The small firm builds projectors into phones, effectively allowing users to splash their display onto the nearest white wall or desktop surface.
“Customers are frustrated with small screens,” says Microvision’s spokesperson Matt Nichols. “We think that the real growth in the phone market will come when users can experience viewing from their phone on the level of their laptop or home television set.”
Microvision plans to begin integrating its projectors into cellphones in mid-2009. Bigger companies jumping into so-called “pico projectors” include Texas Instruments (nyse: TXN – news – people ) and 3M (nyse: MMM – news – people ), which has announced that it will integrate projectors into Samsung devices–possibly including cellphones–sometime this year.
Another sci-fi-like feature long desired in phones is video conferencing–face-to- face chatting via cellphone. But two-way video still strains the capabilities of current cellular networks. Japan’s NTT DoCoMo (nyse: DCM – news – people ) is one of the few mobile operators that allow subscribers to make such calls. AT&T (nyse: T – news – people ) has a similar service, Video Share, which supports real-time chatting one way at a time.
In a few years, true video chat may come to the U.S. courtesy of Clearwire (nasdaq: CLWR – news – people ), a fourth-generation (4G) wireless network that Sprint (nyse: S – news – people ), Intel (nasdaq: INTC – news – people ) and a passel of other technology companies are building. The new technology, called WiMax, will have the bandwidth to support video conferencing, says a spokesman.
Capabilities like these make 4G connectivity an important feature in any future phone. U.S. carriers say they will upgrade their networks to this faster technology within the next three years. Sprint is banking on WiMax, while AT&T, Verizon Wireless (nyse: VZ – news – people ) and T-Mobile have said they will support a technology called LTE.
The 4G technology will offer connection speeds three to five times faster than current networks, support more users on the same spectrum and stabilize service (fewer dropped calls). That translates into new services and existing services for a cheaper price, says Scott Wickware, vice president of business development at Nortel. Expect to see networks by 2010 or 2011.
