Wireless Broadband

There is a piece in Technology Review about 5G wireless.

The writer states:

Samsung says its new transceiver can send and receive data at speeds of more than a gigabit per second over up to two kilometers—and it could deliver tens of gigabits per second at shorter distances. This compares to about 75 megabits per second for the latest standard, known as 4G LTE. The Samsung technology relies on 28-gigahertz frequencies, which can carry commensurately more data but can be blocked by buildings, people, foliage, and even rainfall.

Samsung says it has greatly mitigated these problems by sending data over any of 64 antennas, dynamically shaping how the signal is divided up, and even controlling the direction in which it is sent, making changes in tens of nanoseconds in response to changing conditions (among other features, it can catch stray reflections of signals that had bounced off an obstruction).

In my review of the Crawford book I indicated as such. This is just the first of many embodiments of Gbps to the user wireless. This is also why Verizon abandoned FIOS and why one should wonder about CATV.

It continually amazes me how regulators and lawyers are often clueless about technology and develop policies based upon bad technology and ignorance of what is doable. Well that is Washington after all.
