Will AT&T users be blown away by introduction of CA in the Windy City?

10 Mar 2014

AT&T Mobility has introduced carrier aggregation (CA) technology in Chicago – and a number of unspecified markets – with a view to boosting its LTE capacity and speeds. According to US technology website GigaOM, the development was confirmed by Kris Rinne, senior vice president of network technologies in AT&T Labs. In Chicago, AT&T is using CA to transmit over both 700MHz spectrum and 2100MHz AWS spectrum, increasing theoretical download speeds to around 110Mbps. However, it is likely to be some time before AT&T introduces the speeds to the mass-market: the telecoms giant currently only has one device that can support LTE CA, a mobile hotspot called the ‘Unite’ which it started selling late last year.
