Airvine, the first company to develop a multi-Gigabit-speed wireless backhaul system for indoor connectivity, today announced the general availability of its WaveCore product line. Designed to eliminate the expensive and time-consuming drilling required when confronting concrete barriers (which includes labor, permitting and inspections) to link areas with Ethernet cabling, the WaveCore system consists of a simple point to point bridge with two nodes, measuring 10.1" x 2.7" x 10.3", that are installed one on each side of a concrete wall or floor / ceiling.

The WaveCore is a PTP (point-to-point) layer 2 Ethernet bridge that operates on PoE (power over Ethernet) or a 12 V DC input. Testing with select customers earlier this year has shown results such as a 3 Gbps connection through 8" of concrete in the middle of a 54-foot link and a 4 Gbps connection through a 12" concrete wall in a garage that was in the middle of a 6-foot link.




Concrete walls average 20 cm / 8 in. or more in Commercial Real Estate (CRE) buildings around the world. These types of walls can form a building's perimeter, serve as interior load bearing walls and as protection for spaces such as fire control or network server rooms. Connecting rooms or production areas separated by such walls can be even more problematic than connecting scores of Wi-Fi APs and other equipment in a wide open and spacious factory floor, as it often involves drilling a hole averaging 6" in diameter through the wall, which is known as "core" drilling.

Furthermore, almost all floors in CRE structures are made up of concrete and rebar with a thickness of 4 to 5 inches minimum. To connect the floors, current practice consists of either routing cables to the nearest elevator riser shaft or existing riser or drilling through the floor.

In addition the WaveCore will prove useful in meeting connectivity requirements for fire control rooms. Such rooms are often located in the basement and surrounded by thick concrete walls. These rooms are mandated to have connectivity to the outside world (to the fire department and perhaps other first responder entities) and today typically use 3G connections. Unfortunately for building owners, 3G is now being phased out and 5G does not have the signal propagation to penetrate concrete walls and/or ceilings. Instead of core drilling to connect the outside world to the fire control system with a cable, a WaveCore link can deliver this connectivity cheaper and faster.

"We have proven with customers for more than a year now that the WaveTunnel provides cost-effective Gigabit-speed connectivity in MDUs, factories, warehouses, conference centers and other similarly large properties," said Vivek Ragavan, CEO of Airvine. "However, we could not achieve the company's founding vision of providing pervasive indoor wireless connectivity because we literally kept running into concrete barriers. The WaveCore system surmounts these obstacles and enables us to connect wirelessly any building with any floor plan anywhere."

The combined WaveTunnel and WaveCore solution is managed by the VineSuite software platform, which facilitates network set-up and operation.

"We trialed the WaveCore bridge at one of our facilities and we were amazed by the ability of the WaveCore bridge to blow through several inches of concrete with a multi Gbps signal," said JP Plouffe, Regional Vice President of CSI. "We can see where the WaveCore would save us considerable time and money when we need to connect adjacent rooms or areas separated by such a barrier."

Why not just drill a hole?
 
Why not just drill a hole?

In commercial buildings? Fire Protection and isolation is one reason. Plug and go for the IT dept. who don't want to be doing physical engineering perhaps? Building rental T&Cs is another.

But yes, a small hole for a couple of cables to create a bridge between routers/switches on either side is surely an option, you don't need a 6" core.
 
That tingling sensation you feel when standing next to the transmitter is just weakness leaving the body.

I mean these things dont just stick to wall either, they need to be mounted and i guess this will require holes as well. At least two on either side of the wall. Then you need power on both sides which will require even more drilling and mounting. Even a rather large .5" hole, could take 4-8 CAT7 Cables with 40GBe each.

As one of those It guys: Fire Protection isnt hard to implement, run the conduit then fill it with fire stop once cables are in. Normally it comes down to Management not wanting to pay the overtime to do it when people are not there.

Cables are more reliable for backend service anyway. Running an office over a wireless bridge is just insane.

Aint nobody running 40GB over "cat7" (BTW, cat 7 is not a recognized standard like cat 6/e is). At best "cat 7" as was certified in 2002 was only for 10Gbps over 100m and made redundant with cat6e.

If you are pushing 40Gb you are doing it over fiber with SFP+. It's cheaper, far more reliable, and actually works.
 
This must be even costlier than the Epson UV printer.

Maybe you're standing next to that other transmitter. Remember, electric power must also enter that zero-hole room somehow.

And don't worry about that melted chocolate in your pocket. It's tastier that way.

Which band is this thing working at, though? Surely it won't end up jamming something else?
 
I mean, it's cool that we can do this, but at the same time I'm about to start hearing it through my speakers. I (probably) can't move this to a windowsill 2m away and solve the issue.

There has to be a better extant solution for this kind of thing. Cables in the ceiling, a hole in the wall, accommodating for this requirement before the building is, in fact, built. Something.
 
I'm wondering what data rates one can achieve by using readily available directional wi-fi antennas and amplifiers.
