As part of its "Enterprise Seamless Mobility" initiative, Motorola has introduced the CN620 Mobile Office Device ("MOD") that runs Windows CE 4.2 and supports both GSM/GPRS and 802.11a communications. The device can seamlessly switch between WLAN and cellular modes when the user walks from inside to outside of a building, Motorola says.

According to Motorola, the MOD merges WLAN and cellular technologies in a single device for easier, more efficient, access to voice and data networks both inside and outside the office. Users can be reached inside or outside an enterprise at a single phone number, and can retrieve messages from a single voice mailbox. Users can actually walk out the door of the enterprise, mid-call, and seamlessly flow from the company's wireless network onto the cellular network without interruption, Motorola says. Additionally, a "micro mobility" capability enables in-process calls to be handed off between WLAN access points as the user walks around throughout a facility that has multiple Wi-Fi hot-spots. The device even provides "push-to-talk" voice messaging within a Wi-Fi enabled enterprise.

The CN620 boasts a clamshell design with two displays. The internal display features 176x220 pixel resolution with 64K colors. The external one is a 2-line, 96x32 pixel monochrome display. The CN620's keypad provides "one point navigation," to simplify direct access to the most commonly used features of the device, such as voice mail, email, contacts, and calendar.

Features and specifications of the CN620 include:

Processor/RAM -- currently unspecified
Storage memory -- currently unspecified
Operating System -- Windows CE .NET 4.2
Display:
- Internal -- 65K Active Color, 176 x 220 pixels, 34.8 x 43.6 mm active area

Wireless communications:
- WAN -- GSM /GPRS; 850/1900 MHz
- WLAN -- 802.11a
Dimensions -- 97 x 52 x 29mm
Weight -- 145g

Motorola introduced the MPx200 last September, the MPx and MPx100 in February of this year, and the MPx220 earlier this week.
