1 INTRODUCTION
The VIP 110-24 is the building block of the Wi-Lan Technologies Inc. proprietary “VINE” Network
topology. The VIP 110-24 is used to interconnect ethernet LAN’s (Local Area Networks) and WAN’s
(Wide Area networks) across large distances, creating a virtual single network. This unique network
topology can also be used to provide broadband internet access by a Service Provider or to
interconnect multiple nodes in a private network.
The VINE technology allows a complete wireless network to start with as little as two radios, and
gradually grow, a node at a time, into a very large and complex wireless network. New nodes can be
added at any time with the sole requirement that they must have line of sight connectivity to another
node already on the VINE. The new node, once attached, becomes a potential attaching point for
other nodes.
VINE uses time, frequency, and directional diversity to coordinate the Medium Access for all the
nodes. This well choreographed diversity allows multiple nodes to transmit without collisions in the
same geographical area. This results in a very high air time utilization which translates into superior
throughput performance.
VINE is designed to specifically address the following requirements:
•
Gradual deployment and expansion
•
Long distance between nodes
•
Non-Line Of Sight (NLOS) connectivity through multiple hops
•
Node by node Quality Of Service Options: Minimum and maximum user data rate settings
separate for inbound and outbound traffic
•
Highly efficient air time utilization
•
Efficient delivery of broadcast traffic (necessary for network management)
•
Fair network availability under heavy loads (a few nodes with heavy load must not “choke”
the network availability to all other nodes)
•
Independent RF data rates and power selection on each individual link.
•
Self configuring allowing new nodes to be added with minimal configuration
The VINE network topology and protocol is explained in greater detail in chapter 3.
The VIP 110-24 is a Spread Spectrum transceiver that implements the VINE protocol. The radio
includes a 10/100-Base T Ethernet port for connection to the Local Area Network (LAN). Each radio
operates in a self-learning bridge mode. Any Ethernet station connected to the local LAN can see all
other stations connected to any of the other LANs at the remote sites. No special configuration of the
user stations is necessary, as each of them believes that there is just one Ethernet.
The VIP 110-24 is a Spread Spectrum radio operating in the “Industrial Scientific and Medical”
(ISM) band from 2.400GHz to 2.4835 GHz. Spread Spectrum technology allows operation without a
license with an output power of up to 23 dBm at speeds up to 11 Mbps (mega-bits per second).
With exception of the indoor power inserter, all of the VIP 110-24 electronics are included in a
watertight outdoor unit enclosure. A single CAT 5 cable carries the Ethernet data and DC power to
