Mangalore University to launch WiFi enabled campus on March 28

Mangalore University is all set to make its campus fully WiFi enabled from March 28. At present, it is making available internet services through two independent Internet service providers - one is through National Knowledge Network (NKN) which is high speed connection of up to 1Gbps and other through 10Mbps leased line from BSNL. Entire campus is configured as a set of Virtual Local area networks (VLAN). 

The connectivity within department is extended through CAT5/CAT6 UTP cabling, while connectivity across building is established through OFC backbone. Core switch at the computer centre provides high speed switching required across campus network. Switch in the department/office/building is used to provide wired connectivity to class rooms/faculty rooms/labs, V R Nanjangud, director, Computer Centre, Mangalore University said. 

Currently, internet access is made available to all users only through wired Ethernet outlets. Hence even the laptops need to be connected to the outlet in order to access the internet services. Wired outlets, though very useful, are location dependent and involve connecting a patch chord between the device and outlet. There are many occasions which call for location independent internet access without the hassle of using the patch chord. 

This is all the more important as most of the students/research scholars/other stake holders have smart devices which can be used to share information on the move. Thus there is a need to provide Wi-Fi connectivity access across the campus to enhance the quality of academic and other interactions. The new WiFi system will enable university to provide any time any where access to Internet on the campus, Nanjangud said. 

It will also ensure adequate coverage so that the access is effective almost at all points in the space inside the building. ensure adequate throughput so that user go through satisfactory experience while using data, audio, video on the net; ensure adequate security - both for connectivity to Wi-Fi network and data transported over air using the Wi-Fi network. 

TO achieve this, university has set up a solution that consists of central controller and access points distributed across the campus. The access points confirm to the IEEE standard 802.11 ac, which ensures ideal data transfer speed of 1300Mbps. There are 190 indoor access points deployed to give coverage within the buildings on the campus and 10 outdoor access points to give coverage in open spaces outside the buildings, the director noted. 

All the access points are controlled by central WLAN controller. This controller controls major functions of access points such as authentication, encryption, quality of service etc. This also acts as management console to configure the access points by the administrator. "We have provided a redundant controller to ensure high availability, in the event of failure of main controller," Nanjangud said noting to the reliability of systems in place. 

Acknowledging the fact that security is the major concern in Wi-Fi usage, Nanjangud said, "We have ensured adequate security - both for connectivity to Wi-Fi network and to the data transferred over the air. The user is allowed to access only through the registered mobile device, where MAC id of the device shall be the identifying feature. Additionally user has to authenticate using the user name and password assigned to him/her."
