AT&T’s new souped-up LTE network is live in Chicago, but you’ll have to wait to use it

AT&T’s LTE network in Chicago recently got a lot more powerful. AT&T is the first carrier in the US to use a new LTE-Advanced technique called carrier aggregation to bond together two 4G networks, the end result being a big boost in speed to the device.

The new network configuration has gone live in several markets, AT&T SVP of Network Technologies Kris Rinne said, but the only specific city she would identify was my hometown of Chicago. AT&T actually isn’t doing much to tout the network upgrade, and that’s likely due to the fact that only a handful of its customers can actually take advantage of it.
