PART A
Introduction
The main purpose of this paper is to design and implement a wireless LAN which
would be including the wireless security solution along with intrusion detection and
prevention. The design would be consisting a wireless LAN security solution plan where the
user need to authenticate themselves with the organizations Active Directory Domain and
alsong with this the staffs of the organization would be provided with an managed device of
the organization whereas the students would also be encouraged to bring their own electronic
devices. The students would be allowed with a facility of getting connected to the wireless
LAN. The management of the organization would also allow the guest users to get connected
to the network whenever they visit the organization for attending meetings however for the
accessing the network they need not to have an active account Directory account of the
organization.
Topology and deployment Model
A hierarchical design model is used for the development of the wireless network and
the network is divided into core, distribution and access layer. The hierarchical design model
allows each of the layer in the network to perform specific function and simplifies the design.
It can also be used for scaling the network and increasing the consistency of the network. The
management of the hierarchical design model is simple and the faults in the network can
easily isolated and the resiliency can be improved.
The only disadvantage of this model is that the flexibility of the design is poor and if
there is a need for expansion of the network many of the network device needs to be
reconfigured.

RF Plan and Site Survey
This is considered to be one of the most important component for the deployment of
wireless LAN. This real time wireless RF plan would be associated with showing the overall
coverage throughout the campus by making use of the heat map. Along with this a RF plan
tool is also to be used before the deployment of the wireless network takes place so as to map
out the locations which are optimal for the access points that are based upon various factors.
Two major things are to be considered while making the plan. The first and the foremost
component is the obtaining of the proper floor plan of the entire campus. This floor plan
would be a CAD architecture or a JPEG file. In case if it is seen that the map or the plan is
not prepared for the purpose of scaling the RF signatures then it would not be correctly
represented and this would be responsible for incorrect representation along with which the
distance between the devices would also be not represented accurately. All this would be
responsible for miscalculation of the distances between the access point and the devices
which would be initially leading to inaccuracies. Another important component of making a
proper RF plan is the dimensions. it is essential to have the area of the campus which includes
the dimensions, length and width. After considering the dimension the plan is made. The
number of floor along with the distance between the floors is to be determined along with the
number of users and number of users per access point. Some other things that have been
considered includes the following:

 Radio type(s)
 Overlap Factor
 The Desired data rates for the access points
 Desired monitoring rates for AMs
 Areas of your building(s) where it is necessary to have coverage
 Areas of your building(s) where there is no need of deploying an Access point or
cannot be deployed
 Areas of your building(s) where there is a need of deploying 802.1x Hotspot (Zone)
 Any area where you want to deploy a fixed AP.
Procurement of Equipment
With the evaluation of the wireless network technology there has been a proliferation
in the offerings made by the manufacturer in terms of the equipment’s as well the tools
related to management. Besides this it is also very important to understand the fact that
different vendors are associated with providing different type of solutions which are having
differences with respect to their technical points. Along with this it is also essential to
consider the architecture provided by the vendor along with considering the hardware,
software and the management tools and how this components meet the requirements and
budget of the organization so it is recommended that the offerings from multiple vendors is to
be sought and combined with the quotations made by the various wireless system integrators.
All this are to be sought so as to provide the results which are the best in accordance to the
needs of the organization.
