In an effort to respond to the growing demand for constant mobile connectivity, Comcast (News - Alert) on Friday introduced a personal 4G/3G Mobile Hotspot, known as the MiFi 4082.

Built by Novatel Wireless, the new pocket-sized MiFi enables users to connect their laptops, tablets, smartphones and any other WiFi (News - Alert)-enabled device to the Internet while on-the-go. Owners of the mobile hotspot can connect as many as five devices at the same time.

“This new product gives customers the flexibility to instantly create their own secure hotspot everywhere they go,” Tom Nagel, senior vice president and general manager of Wireless Services for Comcast, noted in a statement.

“Consumers want mobile Internet access for Wi-Fi-enabled devices like iPads, laptops and smartphones, and with this offering they can share their connection with family, friends or colleagues and can even watch TV and movies on-the-go,” he added.

The mobile hotspot will only cost consumers a one-time fee of $25. However, users must also subscribe to Comcast's Xfinity Internet 2go service. The Boston Globe speculates that the mobile Wi-Fi device will add another $49 or so on top of some consumers' Internet bills. Those who don't already have an Internet 2go account should check out this map before signing up to make sure that 3G and 4G services are available in their area or locations that they often travel. As one would expect, 4G service is relatively scarce compared to 3G.

When within a 4G network, Comcast's new hotspot can provide users with download speeds of up to 6 Mbps. The maximum speed drops to 1.4 Mbps when on a 3G network. The device will automatically roll to a 4G network when it becomes available.

The MiFi 4082 is password-enabled, meaning unauthorized users can't just jump on the hotspot whenever it enters their area. The device comes with a rechargeable battery for times when power outlets are unavailable.
