Jeff Richardson, iPhone J.D.:

Yesterday, T-Mobile and Sprint announced that they will merge. If the government approves, then we will have only three major wireless companies in the United States. In the communications that I have seen from the two companies, including a joint website that went live yesterday, one of the main themes was that this merger would promote 5G, the next generation of wireless technology. This makes me wonder, what will 5G bring us, and when can we start to use it on the iPhone?

And:

The CTIA, a trade organization for the wireless industry, says that 5G can be 100 times faster than 4G, and a chart on its website predicts a transition from 100 Mbps download speeds to 10 Gbps. 5G will also feature low latency that can make the internet five times more responsive when you initiate each request.

All very interesting, but the most interesting nugget in the piece?

To date, wireless cell technology has been based on huge towers with antennas 125 feet in the air which would provide service for several miles. But it turns out that 5G will be different. 5G is much faster, but the signal doesn’t go nearly as far. So instead of a smaller number of tall towers, 5G will work with a large number of microcells placed around 500 feet apart, often on streetlights or utility poles.

But it won’t just be that microcell on a utility pole. As reported by Allan Homes earlier this year in the New York Times, “[m]uch of the equipment will be on streetlights or utility poles,” but it will often be “accompanied by containers the size of refrigerators on the ground.”

That’s a pretty significant infrastructure requirement. Which, to me, means we’ll only see 5G in the most urban settings.

The whole article is fascinating, suggests we’ll first see 5G iPhone/iPad support in 2020.
