KVH’s TracNet 100 Mobile Internet System combines the company’s mobile Internet receiver with Microsoft’s MSN TV service.

Where EVDO service is unavailable the system defaults to 1XRTT service, with data rates up to 80 Kbps, according to KVH. A wireless keyboard controls the system, which doesn’t require a computer. TracNet 100 also turns the boat into a “floating mobile hotspot” for WiFi-enabled laptops, PDAs, phones and gaming systems, the company says. The system is for use on U.S. coastal waters and is to debut this summer. KVH says the price will be less than $1,500, with an external amplified antenna for extended range. Service will cost less than $100 per month. KVH Industries Inc., Middletown, R.I. Phone: (401) 847-3327. www.kvh.com
