Wireless Local Area Networks A wireless local area network (LAN) is a flexible data communications system implemented as an extension to, or as an alternative for, a wired LAN. It uses radio frequency (RF) technology, to transmit and receive data over the air, minimizing the need for wired connections. A wireless LAN system can combine data connectivity with user mobility. The data to be transmitted is modulated onto the radio waves, called carriers, and then are removed from the carriers at the other end by what is called a transceiver. End users in a wireless local area network access the network through adapters such as PC cards in laptop notebook computers.
Wi-Fi can attract people to certain hotels if there is Wi-Fi there. This shows how well used Wi-Fi actually is. Many smartphones now have built in Wi-Fi to allow people to use the internet. How is it used? For Wi-Fi to work you need to have certain equipment such as a router and a modem.
Our Project demonstration is based solely on wireless internet technology. Basically, what we set out to do was to prove that a wireless internet connection could actually be made, and that it could made to be, at least somewhat, secure. Our goals are listed below: 1.-Setup a wireless connection to the internet. 2.-Ensure that the connection can be made and that the signal will remain constant. 3-Using WEP(wired equivalent privacy), ensure that the wireless connection can be made secure.
1. Introduction • Wi-Fi also common spell with Wifi or interCap word WiFi, is one of the most popular wireless communication standards on the market that exchange data or internet by wirelessly using radio waves. Wi-Fi is technically a trademarked brand name for the wireless standard owned by the Wi-Fi Alliance, much like Bluetooth® is trademarked by the Bluetooth Special Interest Group. The Wi-Fi Alliance also defines Wi-Fi as any WLAN product that based on the IEEE 802.11 standard. However, only Wi-Fi products that have complete Wi-Fi Alliance interoperability certification testing successfully may use the Wi-Fi Certified trademark.
1. INTRODUCTION Universal Plug and Play (UPnP) is a standard that enables devices such as computers, other wireless devices, and intelligence appliances1 to be plugged into the same network and be familiar with each other’s existence. UPnP works by users plugging devices into a network with the configuration taken care of, it then obtains a TCP/IP address which is the internet’s communication protocol, and is also applicable to private networks whether an extranet or intranet2. It then uses another protocol which is HTTP, this is the internet’s hypertext transfer protocol and this broadcasts the different devices on the particular network3. UPnP has been deployed but there is uncertainty whether there was adequate consideration concerning its robustness as this may result in safety implications for users.
It has a lot of scope for usage from networking to pairing devices, it provides a wireless connections. There are many other devices, like Smartphone, tablets, Laptops, etc which have Wi-Fi client so that they can access any of the Wi-Fi access point or hotspot to access data services or internet. Research Wi-Fi is a known technology and works on the protocols as defined by IEEE (Institute of Electrical and Electronics Engineers) 802.11 standards. The name Wi-Fi is used as a synonym for Wireless LAN or WLAN. Normally the range of any wireless access point is few meters, however as it work on microware, the range reduces with any kind of obstacles such as wall.
Wireless Networking The term wireless networking is a technology that enables two or more computers to communicate using standard network protocols without network cabling. The industry standard mainly used for wireless networking is IEEE (Institute of Electrical and Electronic Engineers) 802.11. What this standard is could be described as a wireless network with hardware that requires the use of technology, which deals with radio frequencies as well as data transmission. There are two kinds of wireless networks, Ad-Hoc (Peer to Peer), or access point (base station). Ad-Hoc (Peer to Peer) consists of a number of computers each equipped with a wireless networking interface card.
Using radio waves, a wireless network connects a PC, mobile phone or just about anything that connects to the internet wirelessly by a router. By transmitting signals at 2.4 or 5 GHz it allows the waves to transmit more data at a faster rate. Typical Wi-Fi standards are 802.11a, b, g, n, or ac and they can switch up the frequency depending on the model (Brain). Families can create their own wireless network that can be shared between family members without the use of hooking all their devices up to the modem and can also protect their home network from potential hackers with the use of a TKIP or AES encryption. Businesses can also create a “hotspot” which is an area that has wireless networks for free or at a set fee.
Avant Go vs Palm VII There are many people trying to find the best solution for wireless web browsing. At this time there are two major competitors, AvantGo, which uses any standard Palm device with AvantGo Server software installed on the desktop, and AvantGo Client, and Mobile Application Link software installed on the Palm. Then there is the Palm VII device that uses a wireless modem and a connection to a specialized ISP called Palm.net. While using a Palm device with or without a modem, it is possible to access web content. If you have a wireless modem it is possible to dial a traditional ISP and connect to the Internet the same way you would at home with your desktop.
I will also look at satellite, which can be used to provide Internet to remote areas and Wi-Fi which is widely used to access Internet and local networks without having to have a physical connection. I will finally assess WiMAX (Worldwide Interoperability for Microwave Access) that is used to provide Internet over a large distance. Bluetooth was an IEEE (Institute of Electrical and Electronics Engineers) 802.15 standard, but the standard is no longer sustained. Bluetooth supports speeds up to 24mb/s as well as different power ranges, which allows it to travel over certain distances. Short range can travel 10cm, and then t... ... middle of paper ... ...k, or it could be highly used and cause a great deal of strain on the network, resulting in upgrades needing to be made to cabling and equipment to handle the larger amounts of data travelling over the network.
