Introduction of Wireless Networking Technologies

The very first step in the deployment of WLAN is to make sure the required operation initializes with the site survey of the network for the assessment of the behavior of radio frequency within the particular environment. In the wireless network, several issues can arise because of the poor coverage as well as poor planning for this purpose. One thing is discovered that several site surveys are not executed accurately, or the site survey is lost completely. The main purpose of this assignment is to provide the brief information as well as the guidelines for proper planning, preparation, as well as the identification of the access points as well as the roaming spots of the BCU network within one particular building and the specific floor. In the report, a brief survey is conducted as well as the sketch floor map of the selected site to survey. In the site map, the roaming spots are also located. Furthermore, the installation of the new wireless network, the process of planning and designing is described by the wireless site surveys. The roaming capability, rates of data, the service quality as well as the coverage of wireless network should be looked at them and to identify the challenges earlier finding the best ever solution. The report is also telling about the categories of site surveys. There are three main categories that are discussed which are mentioned here for the convenience. The passive site survey, active site survey as well as the predictive site survey. The wireless site survey has several best approaches including equipment, assessment, access points, testing as well as the analysis. These approaches are explained in the report in further sections. The planning for a wireless site survey is also discussed in the report.

II.  Site Survey Planning of Wireless Networking Technologies

To gain the very best results, it deserves if the business of the user is going to use the wireless site survey. The preparation is a vital component that will enable the user to make it happen. The organization must have to schedule the survey at a time because of the crucial element where the minimal disruption will be caused by the operation of the business. The picking a week or the day could be involved where the business is expected for becoming slower a little bit because of the seasonal trends or the training of the staff. On the other side, it can also give the meaning of conducting the site survey for the completion of the hours of the business. Furthermore, the professional network engineer who has the ability to give the reliable as well as fast service which is vital for having the wireless network survey. The user is allowed by the field engineer for finding the easy way for this. In the last, it is also required for making sure that the premises of the business of the organization are safe and secure for the engineer [1].

III Approaches of Wireless Site Survey of Wireless Networking Technologies

To perform a site survey for wireless LAN separately from the hiring of the right engineer at the right time, there are many different types of challenges as well as issues for the consideration of how to conduct a survey for the wireless network. As the owner or administrator of the information technology of the website, it is commanding that the user understands them. The mentioned approaches are used for the site survey of the current area network [2].

A.   Equipment of Wireless Networking Technologies

With a simple wireless internet adapter, the active, as well as passive surveys, may be completed but the predictive surveys need particular equipment. The size of the building will influence the actual specification of the concluding item and the intended use. Furthermore, on the facilities of the hardware, it will require the software to run the number of tests for it. The running of any kind of the operating system such as Windows, IOS, Android, or other operating system’s applications may relate to such kind of software, which depends upon the needs of the business [3].

B.    Assessment of Wireless Networking Technologies

The assessment of the current network infrastructure is the key to whether the organization currently fully boasts the facilities of the wireless network in specific regions. The visual inspections of the regions, as well as the networking devices and the networking facilities which are being used, should be completed by the engineers. The identification of any current features, as well as the determination of the capacity or the capability, can be adapted as well as utilized to implement the network wirelessly may also assist in the designing of the network as well as the installation processes. The user has to make sure that it may also minimize the actual costs on the network through the reduction of the requirements of the equipment [4].

C.    Access Points of Wireless Networking Technologies

The huge emphasis on the concept of the access points should be placed by the wireless site survey, which is necessarily the gateways that are used for the connection of wireless devices with the existing network. Furthermore, it is also making a connection with the internal network for the outdoor digital world. The close attention should be paid by the network engineers for plans of the floor as well as tried for identification of the highest point to place the access points. Moreover, the threat of obstructions will be reduced to signals as well as satellites by it. To airwave pollution of the traffic as well as the factor in the outside obstructions, it is very significant for the engineers of the network.

D.   Testing of Wireless Networking Technologies

The testing phase is the very significant part of any kind of implementation as well as an installation because it is the only process which is capable for finding the problems in the system as well as it can also remove all kind of ambiguities from the system which is implemented. During the phase of planning of the implementation of the wireless LAN as well as the phase of the installation of the network, the network engineers require for testing the coverage of the wireless network throughout all of the areas of the building of the network where the wireless network facilities are required potentially.  The best ever way for doing this is through going or walking across along with the computing devices that will measure the network situation on the current or targeted area.

Along with the download as well as the upload speeds, the strength of the signals of collected data in the manner confirms that the plans of the network are working as wanted or want extra consideration by the further access point in the device for making the strong connection with the network.

E.    Analysis of Wireless Networking Technologies

The analysis is a very important part of any kind of survey and the testing of the system to make changes as well as making improvements into the system. It is a very significant phrase because every kind of ambiguities, issues, and problems, as well as the plus points, are also mentioned or listed. It is actually the comparison of the system as well as the comparison of the different techniques, areas, speeds as well as different kind of solutions which can be proposed for the current system. Furthermore, the network engineers are allowed by the analysis of the data which is collected from the testing by using the tool for the site survey of the wireless LAN to pinpoint any areas where the network is the filtering. More indication can be given by the filtering results through the assured access points. For the improvements, it will be led hopefully after running the second test, adjusting, or adding the new equipment or access points. It should be highlighted by the cross-comparison of the outcomes of the different types of tests, in which the adjustments have worked. In all of the locations or the areas, the objective is to reach total bars on the indicators of the connection of all networking devices. In the last, further tests on the network. Should be reserved as the changing of the requirements as well as the changing in the environment that can affect the overall workability of the network in the future.

IV.   Architecture of Wireless Networking Technologies

Two types of direct trust relations, as well as one, are indirect, are implemented by the federations such as eduroam. The relation of the trust of among the Idp as well as the end-user which is operated by the organization of the home of the user, as well as among a the Idp within eduroam, the operator of such network goes at the visited area or the floor. Furthermore, the trust relationship among IdP, as well as the user, is concluded by mutual authentication. Moreover, trust is also established by the SP as well as IdPs by using the radius hierarchy. The transitive relation of trust is provided by two forms of trust relationships into the turn, which develops the SP trust the user to use resources of its network.

How the Client Roam is triggered?

The client roam is triggered explained here that roaming automatically makes the connections to the access point with the device of the client with the strongest signal in the RF environment. The request of the client go the access point authenticator that the radius server save the data in database which send back to authenticator after processing. After authentication, client or guest can use the services of internet.

What happens to the students eduroam account when they leave the university?

The students in the university connected with the network of the university via their registered profiles. The area is assigned to the students who can use the services. When they leave the university, they cannot use the internet services outside the university boundary.

Describe the authentication and de-authentication process?

Eduroam is secure, world-wide roaming access service developed. Authentication concerns with the security of network in the university. The request is transferred to the authenticator who will sends the data to database for registration. Every data entry is also authenticated in this step. The radius server sends the data after saving in database to authenticator again where the student is successfully given permission to access the account. On the other side, the eduroam operator searches the disconnected accounts or users on this network and the memory will be cleared after filtering it. In de authentication, the attacker can attack on the network where the authenticator can block the data as well as suspicious IP address and remove from the network.

Describe any combination of IEEE 802.11 standards used to provision edurroam.

The combination of IEEE 802.11 standards used for the provision of eduroam is discussed such as the wireless LANs untethered network which mostly used on mobile and laptops. The standard of IEEE 802.11 is Mac protocol which is unlicensed frequency spectrum from 900Mhz to 2.4 Ghz.

Describe the various security protocols which make eduroam one of the most used wireless roaming solution in academia.

The various security protocols that can make eduroam most used wireless roaming solution in university. The Mac protocols of 802.11 can be used for this purport as well as it can make it better.

Evaluate the data rate before, during and after the roaming event? Include any data you have recorded while you undertake the work required in the first part of the task.

The data of the clients or the users in the university using the services of eduroam vary on the usage. The data before roaming was low but during the roaming and after the roaming, the data did increased

Provide suggestions on how eduroam would be improved in terms of security, QOS, roaming and coverage.

The wireless project drivers of eduroam system or the need of the computer for updating on the regular basis. The operating system as well as the protocols should also be updated after some times.

V. Recommendations of Wireless Networking Technologies

There are some issues with this system that need to be improved. It is recommended that the determination of the particular area or the floor which lies within the scope as well as out of the scope for conducting the survey to carry the wireless LAN survey of the site. Furthermore, they display the noise floor by considering the heat maps. Proper determination and evaluation of the key interfaces. The heat maps are intended to provide with the coverage by RF along with the consideration of the targets SNR legend and the SNR. Carry out the initial surveys more accurately and the validation for the final settings of RF. By taking into consideration, these recommendations the WLAN site survey can better be managed and the desired outcomes can be obtained as per the users [5].
