Motorola today unveiled a new mobile handset targeted at the field service worker and boasting some key enhancements.

Chief among those new features in the Motorola (NYSE: MOT) MC9500, introduced today at a press event in New York City, is the ability for enterprise users to select the 3.5G network that best suits their needs -- so far-flung businesses can deploy the same wireless device despite differences in coverage areas.

The MC9500 thus becomes the first Motorola field computer using 3.5G WAN for faster wireless broadband connections, and that also includes universal support for GSM, HSDPA, CDMA and EVDO Rev. A, according to the company.

Known as Motorola MAX FlexWAN, this cellular network flexibility allows businesses to issue a single pool of mobile computers that will provide the best coverage for users in different geographies, Motorola said.

Designed for the transportation, parcel/post, public safety and delivery industries, the Motorola MC9500 also builds on the company's initial model, the MC9000, by adding new battery management technology and an accessory system to organize space for charging cradles, power packs and cables.

The MC9500 is also the first handset based on Motorola's second-generation mobility architecture. It runs Windows Mobile 6.1 and has a Marvell XScale PXA320 processor that runs at 806 MHz.

The updated model also includes an accelerometer that switches screen capture modes between landscape and portrait and aides in signature capture, useful for delivery companies. The MC9500 is equipped with a laser scanner, 2D imager and 3-megapixel color camera, with the aim of facilitating scenarios like enabling users to document condition of delivery.

GPS is also provided, along with Wi-Fi support. A microSD slot supports up to 16GB of expansion storage.
