A major step forward for wireless network infrastructure could also mean faster cellular speeds for you -- especially if you live out in the country. Technology Review is reporting that three US carriers are currently testing a new high-speed wireless solution that relies on laser and radio links, which can reach speeds of around 2Gbps at distances of up to 10Km (around 6 miles). AOptix, the company behind it, claims the links can be daisy-chained together to create much longer connections. It's being positioned as an alternative to fiber, which is prohibitively expensive for unpopulated rural areas. And it's also useful for cities where fiber installations involve mounds of municipal red tape.
