Two new tools can turn your mobile broadband connection into a Wi-Fi hot spot. Netgear's 3G Broadband Wireless Router ($130) plugs into a laptop or USB modem and allows up to 64 people to share one person's connection, though the company recommends limiting your Wi-Fi party to 25. It has a range of about 125 feet. Novatel's MiFi is different: The device has a broadband connection embedded in it, so you can buy one subscription for the MiFi and pass it around among your employees. The MiFi supports five users, with a 30-foot range. It will be sold through wireless carriers for about $200 later this spring.
