Some 310 billion mobile app downloads are expected by Q1/2016, and 70% of smartphones will be 802.11acready by Q2/2015. And let’s not forget about tablets – they consume 3.4-times more traffic compared to a smartphone on average. Networks must contend with this higher demand. Enterprises have also grown more reliant on higher bandwidth, latency-sensitive applications. For example, virtual desktop infrastructures (VDI) are characterized by bursty, delay-sensitive traffic because processing occurs in the data center instead of locally. HD video-capable mobile devices are proliferating. And users increasingly rely on them for fast and efficient mobile telepresence. Collaborative programs like Microsoft Lync, Apple FaceTime, WebEx and Citrix GoToMeeting create two-way video traffic across the network. The use of podcasting and streaming has also skyrocketed. It is therefore only natural to see a huge increase in the consumption of multimedia on mobile devices in the residence hall. Due to the pervasiveness of wireless in some environments, the smart classroom has now become virtualized, which allows its capabilities to be delivered anywhere there is capacity to receive it. The 80/20 rule for download and upload direction no longer exists. New app behavior has completely transformed traffic patterns. For example, smartphones synchronize all photos to cloud-based storage when a user walks into a building and connects to a Wi-Fi
Wireless network infrastructure has become just another connection method for corporate and home users alike. This rapid acceptance can be attributed from:
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.
Each site slated for secure indoor wireless had a site survey done. The site survey method was top-down with the roof as the starting point. As with most site surveys the locations for equipment was identified and the cabling pathways were determined. In addition, a wireless survey was performed to identify possible sources of interference and find best install sites for AP’s. This was performed using wireless analysis tools to get the best installation places.

Guidelines: It’s always best to introduce a paper to the reader. It sets the tone and provides an overview of what will be covered and what the goals are.
Currently billions of mobile devices are connected to wireless networks and by the year 2020 when the massive arrival of 5G to the market is expected to be four times higher. This paper aims to analyze the advances in communication for these networks that will be present in all types of portable devices and personal use in addition to computers. It evaluates the progress for aspects of communication and ability to transfer data and information through new wireless networks. The benefits and improvements in communication and performance in different devices for 5G networks are evaluated; this 5G of wireless networks promises an excellent performance in the exchange of personal, business and institutional data, also this paper

The wireless deployment plan overview is to list out the requirements for the deployment of a wireless infrastructure to a multi-building campus for an education Institute. This campus has a single campus but has many other buildings that are part of this one campus. There will be several lands inside of this network and connecting them together we'll make this a win however when it comes to Camp assist it is called a can which stands for campus area network. There are many aspects to a wireless deployment phase and in the institution of a open network for the campus there has to be something put in place to cover every area and to be able to give the students the connection that they properly need. The network
In today’s society, it is commonplace for one to be electronically “connected”, by using devices like computers, mobile smartphones, gaming devices, tablets or laptops. Typically there is some type of network, which enables us to be connected, such as a Wide Area Network (WAN), a Local Area Network (LAN) or even a Home Area Network (HAN). A WAN is the most expansive type of network commonly used, which can cover large geographical areas, usually by amalgamating multiple LANs. The most frequently used WAN is the internet, which many of us connect to daily. A smaller type of network is a LAN, most often used in the workplace to connect computers and devices in the same office or building, so users can collaborate and efficiently share resources.
The 802.11 provides the wireless LAN services for the clients, the access points, and the network connecting them. The association service is used by mobile stations to connect themselves to APs. Reassociation lets a station change its preferred AP. Either the station or the AP may also disassociate, breaking their relationship. Stations must authenticate to use a security scheme before they can send frames via the AP. With WPA2, the AP can talk to an authentication server that has a username and password database to determine if the station is allowed to access the network. Before WPA, WEP is used but it is easy to compromise. The distribution service determines the route for wireless or wired network. The integration service is used when
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.
The scenario that I had examined is a WLAN Infrastructure Network using a Virgin Media Super Hub (Netgear) , with more than 10 devices connected .
The current network has approximately 3000 end users in which 2500 are students and 500 staff members furthermore we have 240 access points through which any users can connect to the
Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking
As this demand for dynamic and unpredictable data grows, more and more devices have to be added to existing networks and configured accordingly. The need of the hour is to regulate networks centrally and as a whole rather than configure individual network devices and gain more control to achieve flexibility in existing networks.
