Wireless Routers is a wireless local area network (WLAN) that determine the next route of the packet should travel to the destination (Rouse, 2005). It converts the internet connection that was received from phone lines into radio signals and brings convenience to the portability devices that has built-in network card to gain the radio signals to get to the Internet connection (Switcher, 2015). Table 2 refers to the comparison of three models of wireless router.

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,
One of the largest features in Java 8 was the ability to stream over collections of objects. By adding the .stream()-method into the Collection interface, every collection in the java language was suddenly expanded with this new ability. Other data structures like the Map-interface, does not implement the method as they are not strictly speaking collections.
Wireless networks have become a major part in the operation of businesses and in people’s lives. Wireless networks can provide fast speed internet connections without having to use wired connections. Businesses are doing much better with wireless networks because they don’t have to pay the costs of installing wired networks and people can work easier because they do not have wires running all over the place. Now with wireless networks in place, businesses are able to connect to their other branches and buildings within their area as well.
Wireless communication helps businesses more easily stay in touch with customers, suppliers, and employees and provides more flexible arrangements for organizing work. Wireless technology has also created new products, services, and sales channels. If one requires mobile communication and computing power or remote access to corporate systems, you can work with an array of wireless devices: cell phones, personal digital assistants (PDAs), and smart phones. Personal computers are also starting to be used in wireless transmission. Mobile laptop computers equipped with wireless network interface cards link to the wired LAN by communicating with the access point. The access point uses radio waves to transmit network signals from the wired network to the client adapters, which convert them into data that the mobile device can understand. The client adapter then transmits the data from the mobile device back to the access point, which forwards the data to the wired network.
You go to Wal-Mart, Radio Shack, Office Max, Fry’s, or any of the 100’s of places that sell wireless routers and you are wanting to buy the best router for you, however you are at a crossroad. You now find that there are three types of wireless routers B, G, and N, but what one is the right one for you? Don’t know what is the difference, is it out of date, and is there an option for just reading email and basic internet information. Oh you play games and watch a lot of videos. Is the router you pick the right one for your needs?
In this modern era, wireless communication has become a requisite need like water and electricity which is part of our personal as well as our professional life. When we talk about wireless communication, the first word which comes to our mind is Wi-Fi. It uses 2.4-5 GHz RF (radio frequency) to deliver internet access around a wide area. As more and more users are connected to the network, the rate of data transfer gets reduced. So when more people access wireless internet, airwaves gets clogged and it makes difficult to latch onto a reliable signal. Transmission of data is done using radio waves which is just one part of spectrum. We are totally dependent upon this very prevalent service. But it has also many
Continual advancement in technology has led to the extension of wireless accessibility due to Wireless Fidelity (Wi-Fi), an important phenomenon that has been impacting the world over the past decade (Kioskea, 2015). The name Wi- Fi was first coined by Wi-Fi Alliance and it refers to wireless Ethernet 802.11 which defines standards for wireless local area networks (WLANs). But since 802.11 was considered too slow for some applications it was surpassed by extensions 802.11a and 802.11b, and later by 802.11g. Traditionally, this radio technology that uses frequency to transmit data through air was initially originated during late 1980s and was evolved with the fundamental objective of making data communication wireless. But today Wi-Fi has become a necessity for both consumer and enterprise since it does not only represent a means of staying connected at home or at the internet and checking emails and surfing the web, it is also consumed by the users for content purposes such as streaming music and high
It is appropriate for an organization to have an idea on the basic functioning and installation of the LAN and Wireless LAN (WLAN) Wiring Considerations. Focusing on the wireless LANs, they are often the hosts into which the WLANs are connected to. In the process of their installation and maintenance, various processes are involved that include antenna policy, rate of recurrence of the frequencies and the communicating transmitters (Kahmen et. al., 2008).
Wi-Fi even has problems with interference, and output and that is why voice, data, and video technologies cannot be hosted on traditional Wi-Fi. In contrast, 802.16 use a scheduling algorithm. This algorithm allows the user to only compete once for the access point. This gives 802.16 advantages for example in output, latency, spectral efficiency, and advanced antenna support. 802.11 is essentially an implementation of WLAN within a short range like a college for example whereas 802.16 on the other hand is a metropolitan technology whose objective is to interconnect houses for example to allow communication between them and with other networks. Though recently 802.16 technologies has several advantages compared to 802.11. They have a better reflection tolerance; a better penetration of obstacles; and an increased in the number of interconnections. Though 802.16 standard goals aren’t to replace 802.11 in its applications, but want to supplement it in order to form a wireless network web. Despite the similarity in equipment cost, 802.16 technologies require a costly setup in contrast to 802.11 which can easily be installed using low cost access points. Therefore having 802.11 and 802.16 wireless technologies, they both have common components in their operations however with a difference in communication range.
More companies today use wireless local area network because it can help improve their productivity. Having a single broadband network allows employees to have access to their computers anywhere in the office, and connect to wireless printers when available.
A key benefit of both wireless routers is scalability. Their strong built-in transceivers are designed to spread a wireless signal throughout the home. A general rule of thumb in home networking says that 802.11b and 802.11g WAPs and routers support a range of up to 300 feet, but obstructions in a home such as brick walls and metal frames can reduce the range of a Wi-Fi LAN by 25%
Consumer grade equipment that is used in most home network installations, is manufactured to support fairly small environments. Small environments are networks with about five to ten devices connected at the most, at one time. Enterprise grade equipment is created to support large corporate networks with large amounts on users. In the past, corporate wireless networks used multiple access points to ensure continuous connectivity. Today, wireless networking has evolved to enable the use of wireless controllers. Wireless controllers connect access points by using the same SSID and channel for each, which enables uninterrupted connectivity. The wireless controller is the wireless gateway. Corporate networks are established in a similar but more complex architecture as home networks. Networks utilizing a wireless controller base their infrastructure off of a hub and spoke or distributed mesh setup.
Wi-Fi networks use radio technologies called IEEE 802.11 a, 802.11 b or 802.11 g to provide secure. Reliable, fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet and to wire networks (which use IEEE 802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, with an 11 Mbps (802.11 b) or 54 IV1bps (802.11 a) data rate.
Wireless technology has become an increasingly crucial part of today's world. From health care and retail to academia across the world, wireless systems are improving the rate and ease with which data is sent and received. Two specific examples of the wireless technology used today personally and professionally are local area networks (LAN) and personal area networks (PAN).
802.11n (2.4GHz or 5GHz) When 802.11n was introduced in 2009 with the ability to communicate at speeds up to 600Mbps, 802.11n also included the ability to work in either the 2.4GHz or 5Ghz spectrum. In this project we have used IEEE 802.11n standard, because our antenna is designed for 5GHz ISM frequency band for Wi-Fi application. Bandwidth requirement for Wi-Fi is 100MHz for that operating frequency band shown in table 1.1.
