Transcript: Wireless Networks 5 GHz 802.11G Wifi Tech 54 Mbps Frequency Band Wireless personal area networks (WPANs) interconnect devices within a relatively small area, that is generally within a person's reach. For example, both Bluetooth radio and invisible infrared light provides a WPAN for interconnecting a headset to a laptop. ZigBee also supports WPAN applications. 802.11N 54 Mbps 2.4 GHz, 5 GHz 802.11A Bandwidth or max data rate Wireless LAN PAN Compare A wireless local area network (WLAN) links two or more devices over a short distance using a wireless distribution method, usually providing a connection through an access point for Internet access. The use of spread-spectrum or OFDM technologies may allow users to move around within a local coverage area, and still remain connected to the network. Products using the IEEE 802.11 WLAN standards are marketed under the Wi-Fi brand name. Fixed wireless technology implements point-to-point links between computers or networks at two distant locations, often using dedicated microwave or modulated laser light beams over line of sight paths. It is often used in cities to connect networks in two or more buildings without installing a wired link. 2.4GHz 11 Mbps

It is most popular Network and it is used in Home,School and Collages to share devices and connect together same Internet Network for example: WiFi. Wireless Wide Area Network It is bigger than WLAN it used for cities and countries for Example: Antenna. Wireless Network Wireless Man Area Network
Transcript: All you need you know Skaiva, Armandas and Cady Latency is the function of the electrical characteristics of the circuit This is similar to a speed limit as there are variables affecting speed limits like weather, traffic and highway signs, similar to a latency. It is important to note that latency is the amount of time for a packet to travel from 1 place to another. If it's on the internet, it can be affected by routing that an ISP could do. Latency Latency Step 1) Break down the overall latency into parts for The network Application And associated servers. Step 2) Now plot the network and application latency onto a graph. Step 3) You can now identify any patterns and anomalies, to help find out whats causing the bottleneck. Mitigating latency Mitigating Wireless Interference Wireless interference Usually, Wireless Interference comes from 3 sources: Walls. Floors blocking wireless signal. Other Wi-Fi networks which are using the same channel as you. Appliances and electronics emitting radio frequency interface. At home, your Wi-Fi Network and Nest Weave may be affected by one of these but many networks are affected by all three types. This is where wireless transmissions are sent through the air. Overcrowding of wireless signals can affect some frequency bands, and can even make them stop working. Because there is a possibility of interference problems, you should have a technician around. Wireless Network Interference Network If you have any kind of this interference affecting your network, you may be experiencing some of these symptoms such as: Intermittent connectivity or delays when starting a data transfer Slow networks speeds Unexpected disconnections Poor signal strength. Symptoms Symptoms of Wireless Interference The way your home is build can affect wireless communication speed and range. Common materials such as wood and glass do not have much of an effect. On other hand, denser materials such as brick, concrete and metal can make it more difficult to connect and they may slow your network speeds or block your wireless signals completely from reaching different parts of your home. Interference Interference from walls and floors Normally expressed in bits per second It’s the amount of data that can be transferred during a second Solving bandwidth is easier than solving latency To solve bandwidth, more pipes are added. Bandwidth and latency are connected. If the bandwidth is saturated then congestion can occur and latency is increased. However, if the bandwidth of a circuit is not at peak, the latency will decrease Bandwidth can be increased but latency cannot be decreased Bandwidth Bandwidth
Transcript: Types of Wireless Networks ... WPANS: Wireless Personal Area Networks The two current technologies for wireless personal area networks are Infra Red (IR) and Bluetooth (IEEE 802.15). These will allow the connectivity of personal devices within an area of about 30 feet. However, IR requires a direct line of site and the range is less. As with networks based on wire, or optical fiber, wireless networks convey information between computer devices. The information can take the form of e-mail messages, web pages, database records, streaming video or voice. In most cases, wireless networks transfer data, such as e-mail messages and files, but advancements in the performance of wireless networks is enabling support for video and voice communications as well. What is wireless network ?! WLANS: Wireless Local Area Networks WLANS allow users in a local area, such as a university campus or library, to form a network or gain access to the internet. A temporary network can be formed by a small number of users without the need of an access point; given that they do not need access to network resources A wireless network enables people to communicate and access applications and information without wires. This provides freedom of movement and the ability to extend applications to different parts of a building, city, or nearly anywhere in the world. Wireless networks allow people to interact with e-mail or browse the Internet from a location that they prefer. Sara al-mutairi – ShurooQ fhaid 331203372 - 331202291 Comparison of Wireless Network Types Many types of wireless communication systems exist, but a distinguishing attribute of a wireless network is that communication takes place between computer devices. These devices include personal digital assistants (PDAs), laptops, personal computers (PCs), servers, and printers. Computer devices have processors, memory, and a means of interfacing with a particular type of network. most electronics will offer wireless network connections WWANS: Wireless Wide Area Networks These types of networks can be maintained over large areas, such as cities or countries, via multiple satellite systems or antenna sites looked after by an ISP. These types of systems are referred to as 2G (2nd Generation) systems. WMANS: Wireless Metropolitan Area Networks This technology allows the connection of multiple networks in a metropolitan area such as different buildings in a city, which can be an alternative or backup to laying copper or fiber cabling Wireless Network By..
