5G wireless is coming, but it has a lot of challenges to overcome, and we’re not going to be enjoying its blazing speeds until 2020 at least. But, at cable industry group CableLabs’ InformED Wireless event on Wednesday in New York, several experts helped provide new hints about the shape of the technology to come.
One of the biggest hurdles, it seems, is physics – 5G is going to be a millimeter-wave technology, operating at a much higher frequency than existing Wi-Fi. That’s great if the goal is to move a lot of information quickly – 5G speeds could top 6Gbps in the field – but it raises the issue of range.
