What 5G Will Be: Crazy-Fast Wireless Tested in New York City

The world’s biggest cell-phone maker, Samsung, caused a stir last week by announcing an ultrafast wireless technology that it unofficially dubbed “5G.” And the technology has, in fact, been tested on the streets of New York. The system is impressive but is still in development—which is true of all the technologies that will underpin the next generation of wireless communications. When 5G does arrive, it will likely combine new wireless protocols with new network designs, spectrum-sharing schemes, and more small transmitters. 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.
