Data Communication1CSC00240 – Data Communications and NetworksSubmitted ByCourseProfessorDate
Data Communication2AbstractWireless local Area Network (WLAN) can be defined as the network that connects the various networking devices by using radio signals or wireless networking signals. This networking is considered as financial cost effective and is a perfect solution for remote access. Various methods can be considered for the implementation of WLAN as various products or vendors are available. The perfect solution of WLAN must include networking/ hardware devices like firewall, router, NIC, gateways and various software for the remote access, creating VPN. This combination helps to implement secure WLAN effectively. Implementing a secured wireless network is the main challenge for Biomedical Company. This report will focus on physical and logical designs with topology that can be implemented in Biomedical Company by keeping mainconsideration on security on the basis of organizational structure. (Ro, E., 2002).This framework gives adaptability of operation. Server will be configured with very good configuration as it can connect as well as maintain with the clients. All other systems except servers will be configured as clients. As installation of LAN is very expensive for two building, therefore configuring WLAN will be best solution. It will require very less maintenance and will be easy to remove any problem. (Iyer, A. & Badgujar, A., 2013).

The length of both buildings is about 50 meters whereas width is approximately 15 meters. The distance between both buildings is approximately 40 meters. Their main objective is to change the existing network into modified system for making it beneficial as the company grows in terms of number of employees. The existing network is old and that is required to

The 5 star organization wants to set virtual machines that needs to be operated online. The organization wants to implement WAN at the branch offices which are just recently opened. 100 systems will be set up in their branch offices that can be used for video conferencing with other offices. The new branch office is 200 km the head office. Hence, all the offices need to be on WLAN for the future communication.WLAN is similar to LAN. The only difference between them is the radio signals which are used as transport medium in spite of wires. The main purpose of WLAN it is connected with the mobility of the users by implementing it in simple way and easy configuration. The main challenge in implementing WLAN is its security that also includes its legacy as well as complexity in its implementation. The enhanced adaptability of Wireless LANs results in the profitable work groups, better contribution from staff and also satisfies the employees as implementing WLAN makes staff more flexible and it increases the mobility of staff. (Dr. Singh,G., 2012).Analysis of User RequirementsBusiness ObjectiveThe main objective of the organization is to make network better so that the branch offices can communicate with the head office of biomedical organization without any interruption. The organization wants to operate virtual machines online so that employees can have mobility to work from anywhere. The organization also wants to implement video conferencing so that
