Introduction to the CompuMission Wide Area Wireless ISP
Petprops 36 CC trading as CompuMission does business since 1996 as IT solution provider.
As registered and properly licensed ISP, CompuMission opens the gateway today to many internet
accesses, VoIP and other network solutions. A huge network covered already most of the Western
Cape while the development of networks in other places is in the progress.
Under WISP, we understand an integrated Wide Area Network (WAN) system of connecting customers to
the Internet. High-speed wireless data links provide Internet access on a point-to-point and
point-to-multipoint basis for companies, governmental organizations, schools, universities and other
institutions having Local Area Networks (LAN).
The Wireless ISP System is a fixed wireless service between the central node and the client.
It is not a mobile service, at least in most of the cases, The reason for this is:
-- Direct line of sight is required between the central node and the client, and
-- Low power radios and high gain antennas are used for the wireless links to comply with ICASA regulations.
The Wireless ISP System is a land service operating as a Wide Area Network with cells of 10-45 km radius.
It is not a Satellite ISP System. The Wireless ISP System is a bi-directional service, where both the client
and the central node is sending and receiving data. It is not a transmitter - receiver system, every node does
both tasks.
The system operates on a point to multi-point basis, and consists of a base station and several client nodes
within 10- 25 km radius around it. The client nodes connect to the base unit over wireless links. Therefore,
direct line of sight* is required between the client antenna and the base station antenna in order to
establish the wireless connection.
*Direct line of Sight between two points is ability to see from one point the other point without any
physical obstacles, like trees, leaves of the trees, branches of the trees, buildings, walls, roof constructions,
hills, forests.
CompuMission is providing these wireless network services with real broadband internet access.
A solution to those who have otherwise to go without decent internet access or network links between
their different locations.
