Modern Network Technologies Review
There is a large amount of networking technology present out there and more is being developed every single minute. Basically, modern networking technologies can be classified into two types: wired and wireless. The modern network technologies developed these days are mainly concentrated on wireless. The two most popular wireless modern network technologies are the Wi-Fi and the Wi-Max. These wireless communication networks are generally dependent on remote information transmission and make use of radio waves as their carrier waves which carry the user requested information. The band width these technologies offer are mind blowing and hence these modern networking technologies are used in areas where quick and reliable transmission of data is required.
Wi-Fi stands for wireless fidelity, which is actually a rip-off from ‘Hi-Fi’ which is high fidelity. Wi-Fi is a type of wireless LAN. The Wi-Fi modern network technology follows the IEEE 802.11 standards. The Wi-Fi’s have become so common that they are now supported in gaming consoles, personal computers, mobile phones and even in printers. The main advantage of this technology is that it does away with the physical restraints of wires and makes the transmission/sharing of data or accessing of data much easier. Any contents such as audio, video, media or any application can be shared using this. The areas where such modern network technologies are provided are called as ‘hot-spots’. The hot-spots may vary from being a small room to very large areas which covered by the process of overlapping all the access points. Wi-Fi also supports peer to peer networks. The peer to peer networks help a device to directly connect to another device. The above mentioned type of networking helps very much in gaming application where people can connect to other people’s consoles or computers and can host game sessions. The main advantage of Wi-Fi technology is that it allows connection between any two devices which hosts the networking application, i.e. a laptop which has Wi-Fi application can connect to a mobile phone or a gaming console which has the same certified application. We need not necessarily use a router to connect between two Wi-Fi devices. By using the ad-hoc mode, client to client connection can be obtained. The advantages of this technology are varied. The main advantage is that it reduces the cost of installation of wires. This saves a lot of money and also if a wire is being used for networking, any deviation from typical behavior would take a lot of time to solve. With advancements in technology the prices of the chipsets that is incorporated inside computers continue to drop making Wi-Fi a more viable and intelligent option. However like any technology this has its disadvantages also. The foremost disadvantage is that the protocol that is used in encryption method is easily breakable and the data that is transmitted is not as safe as you imagine it to be. However, there are few companies that are coming out with better and advanced encryption solutions which ensure that our data would be safe. The other disadvantage is that it has limited range. The variation in frequency causes variation in the range to which the device supporting this modern network technology can be used.
Wi-Max stands for ‘Worldwide Interoperability for Microwave Access’. Wi-Max allows portable internet access and point to point accesses also. Speeds up to 75 Mb/s can be obtained using this type of modern network technology without the help of wires. There are two types of Wi-Max, one is the ‘fixed Wi-Max’ and the other is the ‘mobile Wi-Max’. As the name suggests a fixed Wi-Max does not support mobility. The applications of this technology are that they can be used to connect Wi-Fi hotspots, can provide alternatives to DSL access, used in portable connectivity and also in telecommunication industries. An interesting fact that is being considered these days is that Wi-Max can take the place of technologies such as CDMA and GSM. The standard that Wi-Max follows is IEEE 802.16 unlike IEEE 802.11 followed by Wi-Fi (fake watches

Usually people confuse between Wi-Fi and Wi-Max as both of these are wireless technologies and begin with the same letters. However, these two technologies have different applications. Wi-Fi uses unlicensed spectrum while a Wi-Max service makes use of licensed spectrum to establish point to point connections. The Quality of service that is used by both these technologies is completely different too. The quality of service used by Wi-Fi is similar to the one used in Ethernet whereas the one used in the case of Wi-Max is a connection between the user device and something called a ‘base station’. The spectral efficiency of a Wi-Max connection is pretty high. This has been achieved by combining smart antennas with SOFDMA (fake breitling). The only limitation is that the speed achieved by using a Wi-Max connection decreases with distance, i.e. both the quantities are inversely dependent on each other.
