How to: Buy a Mobile Phone

Here's an overview of the technology now available, the product options, and how well and far the devices can travel.

Work doesn't stop just because you've left the office. If anything, you just multitask more. So it's critical to get a mobile phone that can work as hard as you do. Today's business handsets have made a massive evolutionary leap from the simple pocket talkers of yore, offering surprisingly effective solutions for managing your calendar, your contacts, and even your business data, no matter where you are. There is no single greatest handset for all users, but with a little bit of forethought, you can easily choose the best phone and service plan for your own business needs.

Built explicitly for business users, these intelligent mobiles make quick work of e-mail, Web surfing, and business data.

BlackBerry The standard bearers of business phones, RIMBlackBerryhandsets are defined by their intuitive keypads and smart, stable software. Because of their wide adoption among large corporations, BlackBerrys integrate easily into business networks of all sizes. Every major cellular provider offers at least a few BlackBerry options, complete with e-mail and data services that let you easily synchronize the handset with PCs and servers back at the office. Traditional BlackBerrys, such as the 8700 series, sport spacious QWERTY keypads for quick thumb typing, while the smaller Pearl models use a technology called SureType to allow fast typing with multiple letters assigned to each key.

Windows Mobile Rapidly gaining ground among business users,Windows Mobiledevices such as the Motorola Q are designed to offer a familiar Windows-style appearance for business users, along with simple data syncing with Microsoft Outlook. Like BlackBerry, Windows Mobile offers a variety of network-side connectivity options so a small company with just a few handsets can grow into a large company with a fleet of handsets without having to throw away all the phones in the process.

PalmPalm Treosmart phones maintain a prominent place among business handsets, thanks in large part to their simple interface. In recent years, Palm has extended its offerings to include Windows Mobile as an option, and also offers BlackBerry Connect service, which makes it a viable choice for larger business networks.

Symbian Less known in North America than in Europe,Symbianis the primary operating system used on Nokia smart phones. It is powerful and versatile, with a variety of options for integration with business networks, although North American small business users will find it more challenging to implement than either BlackBerry or Windows Mobile, because it simply enjoys a smaller market share here--and therefore, fewer support options--than its competitors.

iPhone In June, Apple made its first foray into the world of mobile phones with theiPhone, a svelte smart phone that integrates e-mail, a Web browser, and an iPod into one device. It remains to be seen whether the entertainment-centric iPhone will make the jump into the business world, but it's certainly a promising platform.

Linux The open source Linux operating system is enjoying rapid growth on cell phones, although it has yet to break into the world of business smart phones. Currently a number of initiatives are in the works to create phones as powerful and versatile as the BlackBerry, but they have yet to materialize in the marketplace. It will, however, be interesting to watch as companies like Motorola apply more effort to Linux development on phones.

A Note About Camera Phones Nearly every cell phone on the market today includes a small camera, usually of fairly low quality, built into its chassis. This can spell trouble for businesses that place a premium on protecting their trade secrets, and it's worth considering this problem if you're planning to hand smart phones to your workforce. Fortunately, many of the premium handsets mentioned above are available in both camera-equipped and cameraless models.

Your phone's performance in the field will depend largely on the technology it uses to connect. Here's a look at the leading technologies.

GSM/EDGE/UMTS The Global System for Mobile communications (GSM) is the leading cellular technology worldwide. In North America, it is used by AT&T and T-Mobile. GSM phones use small data cards, called SIM cards, to store information about the user's account, which makes it easy to upgrade to a new phone. Just pop your SIM card out of your old phone and into your new phone, and you can start talking right away. For high-speed data services, GSM phones commonly use a technology called EDGE (Enhanced Data Rates for GSM Evolution). EDGE phones typically offer a maximum data rate of around 236Kbps, which is slow by 3G (third-generation) cellular standards. For this reason, EDGE is not generally considered a 3G technology.

In addition to EDGE, GSM networks also sometimes use a faster technology called UMTS (Universal Mobile Telecommunications System) for genuine 3G data rates of up to 3.6Mbps, which is quite fast. To reach the higher UMTS data rates, you must have a newer device that uses the HDSPA (High-Speed Downlink Packet Access) protocol. Unfortunately, UMTS deployment has been slow in many parts of North America, so it's still not available in all areas.
