Components of wireless network - basics for all wireless networks

Client software and adapter

Each client computer, laptop or mobile device with a wireless adapter compatible clients can connect to an Access Point. The client adapter is a radio transmitter with firmware supports all 802.11a/b/g signals. This is necessary before the device can associate and authenticate with the Access Point. Some access points are client mode do not allow that not every association extensive network of clients reached. wireless client software, the adapter must be Windows platforms with special. The client adapter slot-bus will be integrated with the laptop or desktop PCMCIA PCI slot. They are used to support specific wireless standards, antenna characteristics, WiFi certification, WDS, range and security. Manufacturers of wireless software to be applied for all available items. Below is a list of some> Configure the client adapter settings.

Access Point (AP)

As the name says 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 data frames before transmitting over the network cable. Standard Category 5 twisted pair, the AP Ethernet port Ethernet switch point with a catalyst ConnectPort. The maximum distance between access point and network switch is 100 meters with standard Ethernet design.

Wireless Controller

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

Power Injector

Cisco Access Points have a variety of power options including AC Adapter, Power over Ethernet power injectors. The placement of access points is that in some situations, an outlet is not available. If the Ethernet switch supports Power over Ethernet power injector as an option extends the distancefrom the socket. Distance of 1.24 miles, with a glass fiber media converter.

Power over Ethernet

Cisco Access Point can be used with Power over Ethernet (PoE) network switch modules support this feature. The 300 meters is the same with Cisco pre-802.3af standard. Using Cisco pre-standard Cat 5 wiring pins 1, 2, 3, 6 used to power devices while 802.3af 1, 2, 3, and 6 with 10/100/1000BaseT signaling 4, 5, 7, 8 with10/100BaseT. Select a module network switch with Power over Ethernet standard your AP has implemented and has a power watts per port for your specific equipment. The power switch of the power system must be supported by additional power from multiple devices. Deploying Power over Ethernet, the implementation costs, which reduce the use of IPT, wireless, and Gigabit Ethernet. See documents mains switch on Cisco's website for information on switching modules support PoE networkand power. 802.3af powered device defined in Class 2 to 3.84W - 6.49W and 6.49W in class 3 to 12.95 watts.

Power Patch Panel

Cisco Inline Power Patch Panel can be used where Ethernet switches do not support Power over Ethernet power injectors are not an option. The patch panel circuit does not. Provides equipment via a Cat 5 cable, the maximum of 300 feet at a certain rated power per port. The patch panel connects the access point to the wiredSwitch with a patch cable.
