Introducing Airvine WaveTunnel™

Capacity and Range That Rivals Conventional Cabling

The Airvine WaveTunnel™ system has been designed to provide multi-gigabit indoor backbone transport without the need for cabling of any type. Each node comes equipped with two radios, one focused in the upstream direction and the other in the downstream direction. Each radio can send and receive in TDD mode using one of the six V-band channels (57-71 GHz). Each channel is 2.16 GHz wide and can deliver 4.6 Gbps at the physical layer using 16 QAM modulation, which enables a payload of 3.15 Gbps per radio. Since there are two radios in each node, the total throughput is 6.3 Gbps. The second generation of the WaveTunnel system will push throughput up towards 40 Gbps.

Flexible Deployment Options

Airvine WaveTunnel nodes can operate in a ring or spur configuration. When operating in a ring configuration data can be transmitted in both the clockwise and counter-clockwise directions. In addition to providing a relay function, each node can also add/drop data through local gigabit Ethernet ports. If a node fails, the neighbor WaveTunnel nodes will turn the ring back on itself to automatically recover and keep traffic moving through the network. This is a very useful feature as it keeps critical applications running by giving them two ways back to the wiring closet.

WaveTunnel nodes can be deployed in a near field mode when placed against a solid wall.  In this configuration, the antenna radiates a very disperse signal that can deliver more RF energy through solid walls than would otherwise be the case.

Beamforming

Makes use of phase shifters and an array of 256 patch antenna elements. At 60 GHz, each antenna element is smaller than a thumbtack, so this large array can easily fit into a very small enclosure. The advantage of such a large array is that it delivers a very narrow pencil-wide beam of RF energy to the far end, which greatly increases gain while at the same time reducing co-channel interference.  Large antenna arrays also increase receive sensitivity.

Beam Steering

Allows the unit to lock onto a neighbor node that can be as much as 60 degrees to either side of the unit.  This makes it very easy to install WaveTunnel nodes as the technicians don’t require any special training in how to “aim” the units.  It also allows the nodes to form rings, which naturally turn in a 360-degree arc.

Interference Mitigation

Is effectively mitigated due to the use of the 60 GHz band. Co-channel interference and interference from other networks using the same spectrum is almost non-existent in a properly deployed network. Much of this relates to WaveTunnel design and the propagation characteristics of the V-band.
