The military will speed up wireless internet several thousand times

The US military began to develop a new method of wireless data transmission. The technology should provide encrypted transmission of information at a speed of more than 100 gigabits per second over a distance of about 200 kilometers. This is several orders of magnitude faster than existing military wireless networks.

The project was taken up by the United States Defense Advanced Research Projects Agency (DARPA). The military said that the existing wireless standards do not meet their needs, so they had to take on the development of their own, according to Extreme Tech.

DARPA plans are extremely ambitious. It should be noted that the maximum connection speed, which was achieved on a wired channel, is 339 gigabits per second, and the average speed of a wireless LTE connection is about 30 megabits per second. According to Yandex statistics, the average speed of a home wired Internet in Moscow is 16,5 megabits per second. Thus, the military are trying to create a wireless connection that is approximately 6 200 times faster than the average Moscow connection.

The new standard is able to provide stable communication at a distance of about 200 km between two aircraft. The connection between the aircraft and the ground object will be established at a distance of about 96 kilometers. However, weather conditions should not affect the connection.

Currently, the US military uses a secure wireless protocol TCDL, which provides data transfer speeds in 250 megabits per second. Intelligence data, maps, photographs, orders, videotapes and a lot of other information are sent through the network.

It should be noted that a method has already been invented to transmit up to 2,5 a terabit of data per second using light pulses, but this is only possible at extremely close distances, so the military is unlikely to use this technology.

DARPA claims that the new technology will be used exclusively for military purposes. However, it is impossible to completely exclude the fact that 100-gigabit wireless connection will penetrate into our daily life. In the end, the Internet itself was originally a military development, and then turned into the World Wide Web.

We cut one sheep’s cable and the whole house was sitting without an Internet for a whole week two years ago. Modern communications are too vulnerable, you need to have an analogue reserve. The USA is too keen on new super technologies, but the more complicated the equipment, the more difficult it is to recover in the event of a failure.

which, by the way, has a lot of combat experience, of which none, but experience, and in our country many military men did not participate anywhere. "newspaper" ... you really underestimate them. This is also impossible, it is better to keep an eye out ... as they say

about a reliable connection - I would not say so! Communication is a very important area in the Army, and you are so dismissive here. In the 08.08.08 conflict, the Georgians effectively hammered the Russian communications, effectively intercepted and misled somewhere (“don't shoot, we are our own!” - after all, many Georgian tanks escaped the fatal blow?). And the Russian belligerents communicated with each other by mobile. Is this okay? A serious adversary, the same States that you are laughing at, will liquidate not only the Russians' existing communications (even the Georgians do this), but will hit the operators of the state-of-the-art communications, both providers, and satellites. And then what? Wave flags?
As I understand it, the effects of the so-called single waves, solitons, are being developed in the wireless communication developed by the SBJ. But they are effective and very well protected from interference and other things. So it’s better to overtake than not to overtake

[ShturmKGB]

I am not an expert in this field, but is such a speed necessary? What such huge amounts of information will they transmit in combat mode?

[PSih2097]

What such huge amounts of information will they transmit in combat mode?

Can you imagine how much traffic one crew eats when it is escorted in real time in a battle, it’s not only infantry, but tanks, armored personnel carriers, aviation, UAVs, both strike and reconnaissance, etc.

What will "analog" give you under the influence of interference?
And what do you mean by digital or analog communication? The radio waves are the same there and there. Only digital communication allows you to control the frequency spectrum (or frequency grid) and time windows, bypassing interference and correcting errors in the digital stream using redundancy. And the analog will wheeze stupidly and reliably, although the operating frequency will be clogged with interference by 10% in time (or less).
Digital can easily be closed with long-term durability, at no additional cost.

It is necessary to develop somehow, to duplicate several channels, but as you know, the military does not have one cable. And the speed of the Internet noticed what, "you can fly." The world is changing, everything is developing and improving, and if there is no development, we will live like pygmies in the jungle in harmony with nature.

IGOR AND HENRY.
Thank you, all words are akin to nails in the coffin lid!
"Digit" DARPA Without the participation of our young, perky specialists (Indians too) "Z-c" to do! Therefore, we remain in the hope that the MO is in the subject.

Give everyone a satellite phone and we will be locked in the microwave.
It is better, by analogy with cellular-mobile communications, to have ground and flying repeaters.

Saw, Shura (DARPA), saw! More of such developments, and, most importantly, more expensive! The more "green" will be thrown into the wired and wireless wind, the worse we are. As they say, whatever the child is amused with, as long as it does not touch us ...

[Papakiko]

And the "child" (DARPA) over the past 30 years, OH, how many "lotions and chips"
Some of them you knowingly use in everyday life.

I wonder how high-speed Internet will work after an EMP nuclear explosion?

Army equipment is usually protected from the effect of electromagnetic radiation, this is one of the conditions of the contracts.

[engineer74]

I do not believe in the stable operation of their advanced electronics in the conditions of atomic warfare.

During the war in Yugoslavia, NATO used EMR ammunition, which seemed to have come out sideways.

[aktanir]

I don’t understand why to taunt? We need to work and do something similar. Nowadays, the one who is more informed wins! Amer is not stupid, they understand this and do ambitious things that only now seem like science fiction, and tomorrow, maybe, will become a fact. Not to catch up, but to be an example, it is necessary to follow and come up with something personal, breakthrough and better in this regard. In the meantime, we look at GLONASS and we see a fig ...

[Backbone]

Something hardly believes in such numbers - 2,5 terabits - this is a stream of 300 gigabytes per second. In my opinion it's tryndezh!

[Averias]

There was information that either the Japanese or the stellar ones managed to transmit 1Tbit / s via fayf (or so) on as much as 1.5km, the question is, what happened between the transmitter and the receiver, in theory all living things should die from such a radiation power.

[Averias]

The American military was puzzled very timely. And then damn what it is, "brave" American soldiers cannot normally watch porn in HD quality, and sometimes "heroic" videos cannot be put on a yu-tube. Okay, we’ll somehow in the old fashioned way, warm up the tube radar and knock down their stealth. And then we'll turn on the "Satchel" installation and say goodbye to the American high-speed Internet.

This is YES!
But each country has its own standards for the degree of security. The most harsh were in the USSR. The amers are much softer, respectively, will work worse ...
There are 3 indicators:
-What level can withstand off. state (performance after exposure when turned on)
-loss of performance for the duration of exposure at what level
-operable at what level of active influence

[Andrey58]

All this is certainly wonderful, if not for one fundamental thing. This is radio communication. And the propagation of radio waves strongly depends on the environmental conditions (weather, terrain, crow flew). Not to mention the fact that powerful radiation sources will be well direction-finding.
There is really no alternative to radio communications in the troops.

Ku-band (10,7 to 12,75 GHz) which is used in satellite television.
Even the Ka-band (34700 MHz DPS radars and 1300 MHz bandwidth) is the main application for satellite television and air traffic control at airports.

ALL OTHER Multimode Fiber

=======================
optics:
40GbE and 100GbE / IEEE Std 802.3ba-2010 is already 100 Gb / s Multimode Optical Fiber
Uses multiple lane (communication lines) over OM3 optical cable on 100 m or at distances of 10 and 40 km it is implemented using 4 different wavelengths (about 1310 nm) and optical elements are used with a data transfer rate of 25 Gbit / s (for 100GBASE-LR4 and 100GBASE-ER4) and 10 Gbit / s (for 40GBASE- LR4).

LTE:
The data transfer rate in LTE networks can theoretically reach 326 Mbps

The picture on the screen saver is full of henna.
For the DARPA 100 Gb / s RF Backbone project (or shortly 100G), the Ku-band (10,7 to 12,75 GHz), which is used in satellite television, will be used to compensate for atmospheric phenomena
The only device providing 134Gbps is ViaSat-having a total of 56 transponders

but in the Ka-band (18,3–18,8 and 19,7–20,2 GHz for the Satellite – Earth line, and between 27,5 and 31 GHz for the Earth – Satellite line)

With such "antennas", portable ones will have to be equipped /
BUT WORKS THAT IT IS NOT IN DUPLEX MODE.
Accordingly, to get 100 Gb / s in duplex, it means that a UAV, an aircraft, a soldier on an iPad need to add the same "antenna" and 56 transponders and provide the required power.
