© 2010 - Crabtree Services LLC Your partner in small business computing in Northwest Houston. 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 Made with Xara Networking Wired and Wireless Networking Routers / Access Points Wiring Plants Switches / Hubs Adapters Security Troubleshooting Typical Networking Products Cisco/Linksys Netgear DLink Engenius Trendnet SMC   help@crabtreedata.com
