Wireless Network Components - The Basics of a wireless network

Client software and adapter

Each client computer, laptop or mobile device with a wireless client adapter allows connection to a compatible access point. The client adapter is a radio transmitter with firmware that supports all the signals of 802.11. This is necessary before the device can associate and authenticate with the Access Point. Some access points do not have a client mode, not all clubs customers to extend the scope of the network. Wireless Client software that runs on Windows platforms will be implemented with the specific adapter. The card slots are integrated with the customer bus PCMCIA slot of your laptop or desktop PCI. They are used to support certain wireless standards, characteristics of the antenna, WiFi certification, WDS, range and security. The maker of wireless software must be implemented for all functions. The following is a list of some> Client Settings tab configured.

Access Point (AP)

As the name suggests, an AP (access point) allows the connection between the wireless client or wireless device and the wired network. The AP takes data packets from a wireless client and translates them into standard Ethernet frames of data before being transmitted across the wired network. Standard Category 5 twisted pair connecting the AP Ethernet port point to an Ethernet switch CatalystPort. The maximum distance between access point and network switch is 100 meters with standard Ethernet design.

Wireless Controller

Wireless designs with hundreds of access points to the root on a corporate network is sometimes provide wireless LAN controller. The project provides access points to easily connect to a network switch. The device 4404 WLAN controller acts as a hub between the four network switches support 100 access points. Cisco Wireless Control System (WCS), WirelessNetwork management software that is sometimes used with the wireless controller design for configuration planning and network optimization.

Power Injector

Cisco Access Point have a variety of power options, such as power supplies, PoE injectors and power. The placement of access points so that in some situations, an electrical outlet. If the Ethernet switch supports Power over Ethernet power injector as an option to extend the distancefrom the socket. Distance of 1.24 miles with a fiber optic media converter.

Power over Ethernet

Cisco Access Point with Power over Ethernet (PoE) network switches must be installed modules support this feature. The distance of 300 meters is the same with 802.3af and Cisco pre-standard. The use of used Cisco pre-standard Cat 5 cabling pin 1, 2, 3, 6 to operate electronic devices during 802.3af 1, 2, 3, 6 signaling with 10/100/1000, 4, 5, 7, 810/100BaseT. Select a module network switch with Power over Ethernet standard and implemented your AP has a wattage output door for special equipment. The power switch on the electricity grid must be updated to support the additional power consumption of multiple devices. Deploying Power over Ethernet, the implementation costs through the use of acceptance IPT, wireless, and Gigabit. See the documents on the network switches from Cisco Web site for information about which network switching modules support PoEand power rating. 802.3af powered device as defined in Class 2 to 3.84W - 6.49W and 6.49W in Class 3 to 12.95 W.

Power Patch Panel

Cisco Inline Power Patch Panel can be used where Ethernet switches do not support Power over Ethernet power injectors and not be an option. The circuit of the patch panel. It provides the equipment via a Cat 5 cable that connects up to 300 meters at a certain rated power per port. The patch panel connects the AP to the wiredSwitch with a patch cable.
