WIRELESS NETWORKING CONCEPTS2Answer to Question 1:Channel Reuse in WLANCCI stands for Co-Channel Interference which is defined as a method of crosstalk fromtwo or various kinds of radio transmitter by making use of same frequency (Bellalta, 2016).There may be various reason behind Co-Channel interference. In some of densely populated areait may be possible to have an idea regarding the AP with other AP making use of same kind ofchannel. This will ultimately result in creation of Co-Channel Interference and also reduces someof the over usage of a channel in a particular or given area. Channel reuse property enables or provides dynamic control over the receiver side that issensitivity to make an improvisation of spatial reuse in the channel. The feature of channel reuseis generally applied to non-DFS channel only. It is internally changed for various kinds of DFSchannel and it does not affect the detection of radar signature. Channel reuse feature can beeasily configured to make use of three proper modes namely static, dynamic and lastly disable. The static mode of operation is nothing but a coverage kind of operation which isgenerally based on Coverage Channel Assessment (CCA) methods (Bellalta et al., 2014). TheCCA is maintained as per the needs of configured properly as per the level of AP so that AP caneasily increase the transmit power with decrease in threshold of CCA. In the dynamic mode CCA stands for threshold which is generally based on various kindsof channel loads and it also take into account the location of various kinds of clients which aregenerally associated with it (Bou-Harb et al., 2013). When the option or feature of channel reuseis changed into dynamic kind of mode this kind of mode generally enables the wireless mediumto change into AP.

WIRELESS NETWORKING CONCEPTS3The disable mode does not give any time of support for proper tuning of CCAnotification or detection of various kinds of threshold.

It isgenerally maintained by various kinds of base station (Florwick et al., 2013). In various kinds ofmobile phone this kinds of cells are hexagonal in structure. In the case of radio broadcast somesimilar kind of structure must be developed which is generally based or dependent on variouskinds of rhombic kinds of cell. It mainly ensures or checks the mutual kind or type ofinterference in various kinds of users which mainly remain under the harmful level. Adjacentkind or type of cell generally makes use of different kinds or types of frequencies. In many casesit is noticed that a group or set of C different kind or type of frequency makes use of cluster over

WIRELESS NETWORKING CONCEPTS4the adjacent cells associated with it (Gamage et al., 2014). Various kinds of cluster patterns andcorresponding frequencies are re-used in various types of regular pattern which available inregular pattern over the service area. Cluster pattern and various kinds of frequencies aregenerally reused in various kinds of regular pattern which is fully used in various kinds ofservice based networks. The summation of bandwidth of the whole system is taken to C timesthe total value of bandwidth which is given by a single type of cell. Fig 2: Frequency Reuse (Source: Created by Author) Answer to question 2:WMAN on expanding stands for Wireless Metropolitan Network aims to give a place forimplementation of various kinds of services based on wireless LAN. In this type of placeconnection is generally established by making use of structure of building in a particular area orzone which is taken to have a connection. It generally consists of various types of building in azone or city which can easily make use of back up or fiber cabling. It mainly provides various

WIRELESS NETWORKING CONCEPTS5kinds of cabling which are based on based on single data of various kinds of data points (Ghoshet al., 2012). WiMAX stands for Worldwide Interoperability of Microwave access is a well-known type of Wireless Networking. It is a well-known type of broadband service which makesuse of high rate of connectivity over a large distance which is the main reason of popularityamong various kinds of internet providers or suppliers (Jamil, Cariou & Helard, 2014). There arelarge number of problems which are encountered in WiMAX technology like attack from DOS,man in the middle type of attack. In WiMAX technology there are mainly two type of problems are found or encounteredin the physical layer. Jamming mainly starts by implementing strong amount of noise so it canminimize the capacity of channel which is taken to be suspicious or dangerous innature or value which is taken to be dangerous. The jamming value can beimprovised by improving the bandwidth or amount of power which is provided toa signal. Scrambling is also a type or kind of jamming which is used for short value orvalue of time and it has some kinds of specification which are based on frame ofWiMAX. Scrambles can be easily used for reducing the bandwidth of variouskinds of victims which will improvise the processing of various kinds of datawhich mainly works by making use of some kind of methods of scrambling.Denial of Service (DOS): DOS attack can be considered to be a powerful type of attackwhich is based on various kinds of wireless networks. This can be only established by makinguse of two phased service models (Leith et al., 2012). In the beginning first it is admitted to havea service flow which has a service flow that it is activated or turned off only after a certain limit
