When Internet access is of the utmost importance, the most common solution is to have a 2nd internet connection on standby. The new Netgear Wireless-N 300 router launched in January 2010 at the CES in Las Vegas seems to have all 3G and 4G internet access fall-back options covered.
The Netgear Wireless-N 300 router is based on a standard ADSL2+ modem and shares the fixed internet connection over WIFI b/g/n. When Internet over the ADSL connection is not available, the NetGear router falls back on a 3G cellular or 4G-WiMAX connection.
As already seen with The MIFI and iPhone / Nokia Smart Phone software, sharing a 3G cellular connection over WIFI is gaining momentum. The Netgear Wireless-N 300 router now adds 4G WiMAX to the WIFI sharing equation.
The USB2.0 port at the back of the Netgear Wireless-N 300 router is used to connect to 3G/4G cellular networks using common 3G/4G USB adapter.
