6G MOBILE RADIO How 115 Gigabit/s was transmitted wirelessly over 100 m

Now 5G isn’t working properly yet and you’re already writing about 6G.

Of course, 6G can do everything better. And the speeds will certainly increase. But what exactly the specifications will look like is far from clear.

115GBit would also be possible today via WLAN with directional antennas. (theoretically)

According to the IEEE, 7G is already expected from 2032, and the show must go on

Radio frequencies in the range from 700 MHz to 2000 MHz are suitable for mobile communications.

Radio frequencies < 700 MHz are unsuitable for today’s mobile device designs (smartphones, tablets). For radio frequencies < 700 MHz, radio antennas are required on the mobile device, which protrude clearly from the housing (=> rod antennas, rubber sausages). Mobile devices with rod antennas achieve very low customer acceptance.

If there is a line of sight between the mobile phone antenna and the mobile device, radio frequencies of 2 GHz to 6 GHz can also be used for mobile communications to increase the data transmission capacity.

Radio frequencies in the range from 6 GHz to 90 GHz are suitable for directional radio.

For directional radio, the transmitting and receiving antenna(s) must be very precisely aligned with each other. Therefore, radio link is not suitable for use with mobile devices. The use of radio links makes sense for so-called 5G boosters.

According to the Golem article, radio frequencies in the range from 90 GHz to 300 GHz should be used. Radio connections in this frequency range are “fair weather connections”. In the troposphere, the weather massively attenuates or absorbs the high-frequency radio signal (> 90 GHz) due to humidity, rain, snow and other weather influences.

Therefore, radio frequencies > 90 GHz are unsuitable for reliable (directional) radio connections. Since the cell phone antennas described in the Golem article have to be supplied with energy via a power cable anyway, you can use a fiber optic cable for these cell phone antennas and do without the “short-range, fair-weather radio links”.

A fiber optic cable enables faster data transfer rates than a radio connection. And it is also very resistant to disruption (i.e. independent of the weather)!
