Wired and Wireless Networking
CDS has experience in designing and installing complete wired and wireless networks for homes and
small to medium offices.
The most common wired networks today are twisted pair (TP) Ethernet networks utilizing Category 5 or
Category 6 twisted pair copper wiring. This wiring is similar to what is used for telephones, but network
wiring usually contains 4 pairs of color coded wires with each pair twisted together with a unique twist rate.
This keeps the electical signals traveling through one pair of wires from interfering with the signals in
another pair of wires. The Category number refers to the electrical characteristics of the twisted pair wire
including the frequency and data rate that the wire can conduct reliably. The reliability of your wired
network depends upon the proper selection and installation of the network wiring products.
Wireless networks utilize radio frequency waves to communicate between network devices. Wireless
networks today come in a variety of frequency, speeds, and types ranging from wireless ethernet LANs; to
wireless 3g and 4g WANs; and to Bluetooth PANs. What does all this mean? It means that whatever
wireless networking needs you have, there is a solution out there for you.
For wireless LANs (Local Area Network) radio frequencies of 2.4 ghz (gigahertz) and 5 ghz are utilized
providing data rates from 1mbps (megabits per second) to about 300 mbps. The current standards for
wireless LANs is 802.11 a/b/g/n. Wireless A operates at 5 ghz while wireless B, G and N operate at 2.4
ghz..
Relative data rates are: A=25 mbps; B=11 mbps; G=54 mbps; N=150+ mbps
