Wireless services provider CellularOne this morning announced the launch of Bermuda's first 4G network.Frank Amaral, the company's chief operating officer, said at a press conference that the upgrade of the network, which will allow data speeds up to six times faster on 4G-enabled devices, took effect last week.The HSPA+ (High Speed Packet Access evolved) technology is similar to that being used by US carriers AT& T and T Mobile.Mr Amaral said the network could achieve maximum theoretical downlaod speeds of 21 megabits per second (MBs) and was on a par with the very best wireless technology in use in the world. Customers will be automatically upgraded at no charge.CellularOne expects to offer new 4G handsets later this year, Mr Amaral said.“With 4G data speeds, our customers will be able to e-mail faster, surf the web quicker and stream media faster than those using the old 3G technology,” Mr Amaral said.
