Figure 6: WiMAX vs WIFI coverage
Figure 6 shows the WiMAX and WiFi coverage. Once can clearly see how large is the coverage of WiMAX.
Wi-Fi and WiMAX are corresponding. WiMAX networks usually provides a WiMAX subscriber unit which links to the metropolitan WiMAX network gives Wi-Fi located in homes or business for local devises for example Laptops, Wi-Fi Handsets and iPhones for connections (Xiao, 2008). This makes the users to put the WiMAX Subscriber Unit in the areas, which it can be received best and still are in a position to use WiMAX network for any place within the locality. WiMAX is more similar to Wi-Fi as compared to 3G cellular technologies. Wi-Fi provides local network access for a few feet with speed of about 54Mbpswhereas single WiMAX aerial haves a range of up to more than 40 miles with a speed of about 70Mbps or more than that. WiMAX brings an Internet connection that can serve the local Wi-Fi network.
This refers to mobile stations that assume the part of the source of the network to the user; the second is the access service network that assumes two are additional base stations and constitutes ASN gateways that create the radio access. The last portion of the connectivity network that provides the IP functions and the base stations that gives the air platform for the mobile stations. The stations at the base also avail management functions, tunnel establishment and triggering, radio resources control, active host control protocol proxy, excellence of service enforcement and multicast cluster management. The inclusion of the ASN facilitates the encryption keys, resource regulation, routing to the chosen network and consumer functionality. Connectivity service network is liable for Internet connections...

Long Term Evolution (LTE) products are quickly being seen on the market nowadays and much more products are expected in the future. With 5G proposed and expected to arrive around 2020, engineers must work and test these new products out quickly. However, the complexity of these devices does not make this task an easy one. There are many performance measures to consider such as SNR, SIR, capacity, and many more as well as different features that may be necessary to arrive at the desired results. For purposes of this project, I will evaluate a journal from Agilent Technologies that describes how to quickly determine if a MIMO channel is capable of supporting spatial multiplexing when given a particular signal-to-noise ratio (SNR). The term “condition number” will also be introduced when dealing with recovery of MIMO transmission.
Wireless local area networks (WLANs) have the potential to improve the flexibility, productivity, and the quality of work life of an enterprise (Sage Research Staff, 2001). Berean Institute is a typical two year college with about a staff of sixty eight employees and 250 students per semester. Berean teaches cosmetology, barbering and the latest software and hardware technology, which is located in Philadelphia, Pennsylvania. Berean currently has two locations in the Philadelphia area and using a Local Area Network (LAN).
It provides the Internet data service for facilitating the phone calls with the help of the VoIP system. The service provider also provides connection to the PSTN so as to facilitate the mobile and the landline communication. Thus the service provider provides the necessary connection between your EDGE and the PSTN. The best place to look for service provider is the internet and with so many service providers to choose from can be a tough call.
Bandwidth of channels is always related to spread spectrum technology used in the modulation. Larger channels provide higher data transfer speeds between two nodes. In wireless n technology it has 20MHz and 40MHz whereas 802.11ac has an additional 80MHz channel along with 20 and 40 MHz’s channels with an ability to support even 160 MHz channels.
‘‘If I have seen farther, it is by standing on the shoulders of giants.’’ is very truly coated by Sir Isaac Newton. Ideas gave way to idea. When Marconi invented wireless communication 100 years ago, we had no idea that one day life will seem to be impossible without it. It has penetrated each and every aspect of human life and has resulted into endless demands on bandwidth and spectrum. And by standing on the shoulders of giants, Teletarand Foschinigave the technique of MIMO system which would increase the spectral efficiency of the wireless system to its maximum compared to all the current technologies. Multiple antennas are used for transmission and reception to increases the capacity of the wireless channel.Capacity is expressed as the maximum achievable data rate for an arbitrarily low probabilityof error. Thistechnology received a fillip when TarokhEtA introduced their space-timetrellis coding techniques and Alamouti introduced his space-time block codingtechniques to improve link-level performance based on diversity. Another boost came in form of BLAST Technology. But in this paper, our focus will lie basically on the MIMO wireless channel and how to determine its capacityunder different conditions. And space-time blocks coding techniques. We will discuss the benefits of the topic discussed and future prospects to enhance the usage of limited available spectrum.

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. This is extremely convenient for commuters that need internet access while they are at work, waiting on a plane, or just sitting at a coffee spot without the need for wires (Cox).
G in 1G, 2G, 3G and 4G stands for the “Generation” of the mobile network. Today, mobile operators have started offering 4G services a higher number before the ‘G’ means more power to send out and receive more information and therefore the ability to achieve a higher efficiency through the wireless network. During the time of 1G, radio signals were transmitted in ‘Analogue’ form. 2G networks on the other hand, were based on narrow band digital networks. The 3rd generation of mobile networks has become popular and users access the Internet over devices like mobiles and tablets. This means a 3G network actually allows for more data transmission and therefore the network enables voice and video calling, file transmission, internet surfing, online TV, view high definition videos, play games and much more. 4th Generation mobile networks are believed to provide many value added features.
Introduction: This is a 21th century, technology is the most important and improved thing of the human life. It makes life easier and faster. Development of faster sophisticated technology we have better and fast life. So all we are connect each other by computer network. There are two different way of network: Wired and wireless. Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too.
Most networks have coverage checker so I can check the mobile phone coverage in my area. All I have to do is enter the postal code to see the coverage I can expect. I can get information on the regular 2G coverage for calls and texts as well as 3G coverage. It is also a good idea to ask people in the area if they find the signal strength adequate. The mobile signal strength depends on the provider and where you are. If you want to upgrade to browse the internet or download music videos, you need to make sure there is a strong 3G signal in the area.
One of the latest advancements in wireless data. It is used in GSM (Global System for Mobile Communications) for transferring data in packets.
