Dear Dr. Gentul,

I am pleased to present the final proposal, “Wireless Technology at NJIT” on future
directions for wireless technology at NJIT. This proposal has recommendations for the
wireless network connection problem.

I hope that my recommendations will be helpful as you consider the priorities for the
wireless technology investments. I look forward to discussing this report with you, and
with the members of your department.

Sincerely,

Executive Summary
This proposal was commissioned to examine why the quality of wireless network
connection at NJIT has declined over time and to recommend ways to increase the quality
of wireless network connections.

This research draws attention to the issue about the wireless network connections, and
how much inconvenience they cause for the students and the faculty. Nowadays seven
out of ten students have laptops so they can work at their own convenience. Often time
students lose connection while working on their class projects; this forces them to move
to the crowded computer labs to use the desktop computers. NJIT is a technical college
and not to have a dependent network connection contradicts the title of the institution.

There are various recommendations for this problem, such as
    Buying more wireless routers.
    Buying a repeater for the whole campus.
    Buying antennas for the existing routers on the campus.

                     Wireless Technology Solution at NJIT.

Introduction

Today the Internet is becoming a really important part of human life, where it is really

hard to function without it. The Internet can be accessed through multiple means and it

was made more flexible after implementing wireless technology. The wireless technology

has been implemented in many sectors but the institutions that have gained the most

advantage are colleges and universities. The main reason for adopting the wireless

technology in colleges was not only to increase the flexibility of the Internet usage among

students but also to help students by showing them an easy way to stay connected.

Complaint

NJIT wireless technology has made a great deal of improvement in the network

connection and coverage area for the past few years. It has not only made me a steady

supporter of the wireless network, but also has increased my consistency of staying

connected during the day. However, the implemented wireless technology at NJIT is not

one of the best technologies one would expect from a technical college. After some

research, I found that 7 out 10 students at NJIT think the wireless connection is not of as

high quality as the technical college should have. The continuous interruption of the

network signal and the deficiency of network coverage in some NJIT campus buildings

have forced me to move my attention from wireless to LAN oriented computers. This

problem has created some difficulty of losing network while working in a group to

accomplish class projects. The network interruption problem can be illustrated in

Figure 1.

                      Regular Interruption of Wireless Connection


Solutions

There are several solutions to this problem, such as buying new routers and putting them

in each building of NJIT or adding more wireless repeaters. However, the best solution

would be adding more antennas to each existing router to boost the wireless signal on

every corner of NJIT campus.

Details of the Solution and Advantages

Implementing wireless technology but not integrating them with enough antennas located

at different locations might not lead to getting a strong signal in all parts of the NJIT

campus. The main cause for weak network signals at some NJIT campus buildings is



                                              2
because most of the routers are placed at only one or two locations. This placement

doesn’t provide enough range for the buildings that are located farther away. Hence, the

addition of more antennas for the existing routers for each building will help increase

both speed and network signal for that building and area around that building. Adding

more wireless antennas will improve the wireless signal that is coming from the existing

router. This will not only eradicate the problem of regular network interruptions that

occur for the user during the Internet exploration but also will allow steady thoughts in

the user’s mind of not losing the work. Having a stable wireless connection, which can be

done by adding more antennas will establish positive thinking in the user’s mind. This

way there would be no technological failure of connection but if there is in any antennas,

there are enough antennas that will hold the signal from the router. Furthermore, users,

which mainly include students, will show more interest towards wireless technology

since they will be connected all the time.


Cost Analysis
Improving the wireless connection problem at NJIT could be done by adding more

wireless routers, antennas for each router, or wireless repeaters.


     The cost of buying brand new routers and installing them in several buildings will

     range from $60 to $142 per router. The router that costs $80 is a high quality router

     that covers about 500,000 sq. ft. If we choose to buy the $80 routers (Netgear

     WPN824 RangeMax Wireless Router) for the fifteen buildings at NJIT, the total

     cost would be $1200. The installation cost for routers would be around $150 per




                                              3
     hour. So, the final cost for the wireless routers including installation would be

     $1200 plus the $150 charge per hour.


      The repeater is designed as a bridge to boost the signal for increased distance and

     to operate as a transmission point to relay signals around line of sight barriers. The

     cost of repeaters that range up to 40 miles is from $70 to $400 each. The

     StarTech.com HDMI Extender/Repeater is about $130, and covers about 39ft. The

     installation cost would be $150 per hour. Buying a repeater would be the least

     adequate solution because it is used for network coverage for outdoor purposes.


     The cost to implement new antennas for each router will range from $4 to $300 per

     unit depending on the router that is used by NJIT. There are different types of

     antennas available on the market such as omni, parabolic, dish, yagi, patch, or

     sector. Omnidirectional antennas give the best signal coverage among all these.

     Purchasing five of these (Antenna Factory 15dBi omnidirectional antennas) for $95

     each would total $475, with installation costing $150 per hour.


Conclusion
From the above research I would suggest that the best solution for NJIT’s wireless

network connection problem would be to implement the antennas for the existing routers

in different buildings. Not only is it more cost effective and easy to maintain, but it also

gives more coverage for the campus. The buying new wireless router solution is too

expensive for the college; additionally, the maintenance cost would be higher because the

chances of the routers having technical problems are greater than the chances of problem

with the antennas. Another solution would be to buy a couple of repeaters, but that will


                                              4
not work because repeaters are intended for outdoor instead of indoor usage. So, to

implement that solution would be redundant. Installing more antennas will give the

students better network area coverage and also give them the space and satisfaction of

working in a quiet environment other than the computer lab. Another advantage of

adopting this new system would be that the cost of buying new desktops will decrease

because more students will start using their laptops instead of the desktops in the

computer lab. The students that don’t have laptops will be able to use the desktops

without having to search for a vacant desktop. Increasing the coverage area and

improving the network of Wireless technology will benefit NJIT in the long term.
