TP-LINK announced today that its family of 3G/3.75G Wireless N Routers are now 4G compatible with major wireless mobile phone carriers such as Verizon, AT&T and T-Mobile. The Portable Battery-Powered Wireless N Router (TL-MR3040) is an ideal travel companion to enable up to 5 devices to access the Internet simultaneously on the 4G mobile network. The Wireless N Routers for home networks (TL-MR3220 and TL-MR3420) can now provide 4G mobile Internet as a back up at home when your DSL or cable service is down. Portable-Battery Powered 3G/4G Wireless N Router (TL-MR3040) Mobile users that pair TL-MR3040 with a 4G USB modem vs. a 4G portable hotspot from a wireless carrier can save about $20 dollars per month. Since most carriers also require a minimum of two-year contract, total savings could be up to $480 dollars per contract term. You can avoid extra charges without having to pay for a hotspot contracted through your wireless carrier. Simply purchase your own device and plug in the USB modem stick to create the same mobile hotspot. TP-LINK's family of 3G/4G Wireless N Routers also include the following products: TL-MR3020, TL-MR3220, TL-MR3420 "TP-LINK makes it easy to stay connected using multiple devices wherever your busy life takes you, including at home, the airport, hotel and even in your vehicle. Since all wireless carriers are selling 4G USB modems now and no longer offering 3G, TP-LINK has made the technology upgrade to ensure 4G compatibility for their users" said Lewis Wu, the Director of Sales at TP-LINK USA. "The existing inventory of 3G/3.75G Wireless N Routers is being phased out and the 3G/4G products will be in retail channels beginning November 2012."
