Wireless Networking Essay

An access point is a hardware device or configured node on a local area network (LAN) that allows wireless capable devices and wired networks to connect through a wireless standard, including Wi-Fi or Bluetooth.

There are 9 IEEE 802.11 services in total which can be classified into to categories:

The devices that need to connect are workstations, wireless access points, security cameras, servers, phones and printers, with enough available bandwidth between buildings and devices. The wireless network itself will be able to handle multiple devices and there needs to be enough coverage throughout the campus, including the outdoors. Separate wireless network will need to be establish to ensure that guest traffic does not affect church network traffic.

Wireless network infrastructure has become just another connection method for corporate and home users alike. This rapid acceptance can be attributed from:

Thus the speed and reliability can be improve by judging the number of antennas. In the aspect of data rate, Option 1 has the highest transfer rate comparing to routers that has single-band capabilities. This indicates that Option 1 is able to perform better by transferring 600Mb data per second, 150 Mb more than other routers. Option 1 is strongly recommended as it is more affordable in prices with comparably better performance. Furthermore, Option 1 is equipped with various wireless LAN standard that provides faster and reliable wireless signals. It uses either 2.4GHz (single band) or 5GHz (dual band) band of frequencies in which wireless communications operate. Demands of dual band arise when there are intensive work within a LAN network and provides better internal network performance due to less interference (Lynn,

Wireless access point can be located in the library. The WAP is used to give wireless accessibility to the internet through the router to where it’s needed.

This is a direct extension of the 802.11b that extends the maximum data rate to 54Mbps, making it possible to serve up to five times as many users. Our Wi-Fi network is based on the IEEE 802.11 b/g standards, which is the most commonly used standard. We have added Wi-Fi access points in our network to give easier access to corporate data and services. Most of the devices in this network, for example the personal computers, smartphones, digital cameras, tablets and digital audio players connected using the Wi-Fi technology. The hotspot will be in the range of 20 meters (66 feet) indoors and a greater range outside.

Nowadays there are also keyboards and mousses that can be connected via Wi-Fi. It’s a wireless technology that allows computers and other type of electronic devices to communicate through a wireless signal. Wi-Fi is the most common way to connect computers to wireless networks.

The city of Josuha, Texas has instructed their IT staff to research and choose a way to give network connectivity. The main issue is that the locations that need to be connected are across roads and staff to research a wireless technology to connect four other locations. The issue is that there is not sufficient time to obtain the right of way permission from the two entities who own the road and highway separating the buildings.

Because the first deployment model can cause network slowdowns and affect the normal workflow, it doesn’t make a viable solution. The other deployments models, build in WIPS functionality in the access points and WIPS with dedicated sensors are more common, if not the most widely used and that why it will be my main focus for the analysis.

In large installations, the roaming functionality provided by multiple access points enables wireless users to move freely throughout the facility while maintaining uninterrupted access to the network” (Cisco).

2 For the wireless technology you identified, what is the standard transmission distance and transfer speed? 75 Mbps and 35 miles.

Wireless DSL is a type of fixed wireless which requires a line of sight between communicating transmitters. Unfortunately; this makes its application limited, because in order to be effective, it requires tall buildings or towers. Most multitenant buildings such as hotels, remote office buildings and apartments use this. Transmitters are what connect the building to the ISP, and the DSL used inside the building connects to the wireless transceiver. Fixed wireless can be point to point or multipoint. Satellite is another form of fixed wireless. Both the point-to-point and multipoint versions have data transmissions ranging from 1.5 to 54 Mbps, dependent on the vendor. Mobile wireless service can be set up by the provider in a package one the WAP network protocol is fixed to support it. (Wireless Application Environment) (Fitzgerald, 349-350).

It’s very important to determine the device and application requirements based on bandwidth, protocols and frequency. In wireless network, bandwidth, protocols and sometime environmental conditions affect the speed of the channel so we need to calculate the aggregate throughputs before designing the network. Today, users carry Wi-Fi devices such as notebooks, laptops, tablets and Smartphone’s so total throughput must be calculated by estimating number of connections rather than the number of the seats. Some common wireless networking standards such as 802.11a/b/g/n invented in the IEEE association must be supported by wireless network. For better performance and for faster devices (802.11n devices), dual-ratio access points should be deployed. Table1 [3] illustrate the different IEEE standards and throughput.

A wireless computer can "roam" from one access point to another, with the software and hardware maintaining a steady network connection by monitoring the signal strength from in-range access points and locking on to the one with the best quality. Usually this is completely transparent to the user; they are not aware that a different access point is being used from area to area. Some access point configurations require security authentication when swapping access points, usually in the form of a password dialog box.
