Overcoming Non Line-of-Sight Obstacles with Patented VINE
Technology:
Wi-LAN’s patented
wireless VINE technology is a new networking technology that
overcomes the non line-of-sight obstacles and minimizes
initial up-front costs of developing networks. VINE technology
focuses on overcoming the LOS issues imposed by challenging
terrain topography.
As your network grows,
any node can be promoted to become a repeater; the only
requirement for a new node to get attached is to have RF
connectivity to any node already in the network - a deployment
strategy called anypoint-to-multipoint, since any node already
in the network can become the centre of a point-to-multipoint
branch. Hard to reach locations that are obstructed can easily
be reached once the VINE spreads into that neighbourhood.
Effortless Installation with Increased Performance:
The VIP 110-24 was
specifically designed to operate over long distances. All the
electronics are enclosed in an environmentally sealed outdoor
unit that is mounted in close proximity to the antennas in
your network. This outdoor unit effectively reduces
installation time and eliminates the cable loss, thereby
increasing the range. For long-range links, where the antennas
need to be mounted on towers and rooftops, this configuration
reduces costly RF cables and improves RF system performance.
Quality Of Service:
Total bandwidth can be
shared fairly between all the active radios in your VINE
network, but if your network demands allocation of bandwidth,
the VINE protocol supports different levels of Quality Of
Service (QOS) assigned to individual radios. The network
manager may assign different Committed Information Rates (CIR)
and Maximum Burst Rates (MBR) for each radio, separately for
the inbound and outbound directions. This allows an ISP to
provide different service plans charged at different rates.
However, if the radio is not active, the committed bandwidth
is not wasted, it is shared among all the other active radios.
Network Scalability and
Self-Configuration:
Wireless networks
based on the VIP 110-24 can be deployed one node at a time
without an expensive upfront infrastructure. Each unit
contains complete functionality to operate as a hub, repeater
or an end node. As the number of subscribers grows, a VINE
network can be scaled up in one of two ways:
1. Use multiple radios
at the root location, each feeding a separate sector antenna.
Each of these radios becomes the root of a separate VINE with
full capacity.
2. Break a link
between the root and the remote and reconfigure that remote as
the root of a new VINE (“prune” the VINE). The two separate
roots must then be connected with a dedicated link - a
backbone. This backbone link is only required once enough
subscribers are on-line instead of when the network is first
deployed, allowing for fewer start up costs to your network.
The VIP 110-24 is
self-configuring; at power up, it autonomously determines its
place in the network, finds the addresses of the hosts
connected to the various LANs, and then begins routing packets
appropriately.
