6G Wireless Already Being Developed
6G Wireless Already Under Development
As you know, 5G wireless networks have barely established their presence in America. The rollout of 5G services has been sporadic and uneven, and the equipment for reception of 5G signals has yet to become widely available.
It might seem, then, that we should wait a few months, maybe a few years, to see how 5G works before seeking to replace it.
Some people, though, don’t want to wait. Several electronics firms are already competing for leadership in 6G wireless service. These systems will operate in the ultra-high frequency terahertz band.
Samsung Electronics (South Korea) and Huawei Technologies (China) lead the field. Both have been researching 6G base stations, and each hopes to form the technical standards the whole industry will adopt.
What capabilities can we expect of 6G networks?
Some Samsung and Huawei engineers claim their base stations will support consumer data speeds of more than a terabit per second (1 TB/S). This is more than ten times the speed of the fastest 5G signals measured so far. And the fastest consumer data speeds available from current wireline and fiber internet are about 1 gigabit per second (1 GB/S)- barely a thousandth of what the apostles of 6G are promising. And current 4G LTE wireless systems are much slower than wireline and fiber.
The next generation of wireless networks, then, will be almost incomparably faster than wireless systems as we’ve known them.
Another big advantage of high-frequency signals is low latency. Latency, if you don’t know the term, is the delay between the sending of a signal and its arrival at its destination. Extremely low latency is critical to interactive gaming. Much lower latency will be necessary for remote surgery and driverless vehicles.
With 6G networks, latency could descend to one millisecond. This is about five percent of what 4G LTE networks deliver now.
If there is a disadvantage in terahertz waves, it’s their inability to penetrate buildings or travel far without fading. Each 6G base starion transmits useful signal only about 220 yards. In any given country, then, the number of stations will need to be ten times its population. In the U S of A, this would be about 3.3 billion.
