Samsung had started selling its first USB-based 4G-only modems for TeliaSonera in December last year and promised to launch 2G/3G supporting modem in first half of 2010. Well, they’ve delivered it with the launch of GT-B3730 that will give the same blistering speeds while connected to a 4G network or 2G/3G in case of no 4G coverage.
Like the previous version, this USB modem is based on Samsung’s proprietary Kalmia chip and supports 2.6GHz. It supports 3G on 2100MHz whereas 2G/EDGE on 900MHz/1800MHz. As far as speed goes, 4G can give users a max download/upload speed of 100/50Mbps (megabits); 3G of 17/5.7Mbps; and 2G up to 296Kbps (kilobits).
The modem supports Windows operating systems as well as Mac OS X 10.5 and 10.6.
