Case Studies-1 

A case Studies on Implementing the Wireless Access Points in CUTM Paralakhemundi Campus

CUTM (Centurion University of Technology and Management) Pralakehemundi, Odisha is spread over 120 acres on the foothills of the Eastern ghats in a serene environment lies the main campus of Centurion University.  It is the only technological University in South Odisha having School of Engineering and Technology (SoET), School of Fisheries, M.S Swaminathan School Of Agriculture, School Of Agriculture & Bio-Engineering, School of Management (SoM) , School Of Vocational Education and Training, School Of Applied Sciences. All schools having their infrastructural facilities like CRC-1, CRC-2, Central Library, Girls hostel, Boys hostel Activity Centre, Auditorium, Operator Rooms, staff quarters Gym, Canteens,  etc.  are connected with LAN connectivity. Now University is going to upgrade the existing infrastructure of internet facilities with wireless access points to the whole campus . Prepare

  1. a sketch of a wireless LAN structure implementing different access points.
  2. list access points and its mode of access.
  3.  the steps for installing the access points.
