The speed of 'WiFiber', which is faster than optical fiber, is 1 Gbps to 10 Gbps.

The company name is 'Giga Beam', which is like a relative of GIGAZINE, but it has nothing to do with it.

Well, the early story is the inter-base communication that connects the buildings.

It is a technology realized by using a frequency band close to visible light. Of course, because it is a visible wavelength, it will be affected by the weather. I'm thrilled that the weather is so bad that I can't communicate because of the heavy fog and the pouring rain, but I'm not so vulnerable.

71GHz-76GHz, 81GHz-86GHz, 92GHz-95GHz are used. Since it is not necessary to avoid interference by complicated algorithms, it is possible to make full use of the standard for speeding up by that amount, the use of this frequency band is permitted, and the transmission and reception for making this visible wavelength ray. It seems that it has become feasible because the equipment can be manufactured at a relatively lower cost than in the past by using gallium arsenic.

So, the price you care about is 30,000 dollars including the transmitting and receiving equipment. The reachable distance is up to 10 miles, that is, about 16 km.

By the way, the same kind of thing has already been put into practical use about 5 years ago.
