Mathematical formulation
The model
The Lee Model is formally expressed as:
where
L = The median path loss. Unit: decibel dB
L0 = The reference path loss along 1 km. Unit: decibel dB
= The slope of the path loss curve. Unit: decibels per decade
d = The distance on which the path loss is to be calculated.
FA = Adjustment factor.
Calculation of reference path loss
The reference path loss is usually computed along a 1 km or 1 mile link. Any other suitable length of path can be chosen based on the applications.
where
GB = Base station antenna gain. Unit: decibel with respect to isotropic antenna dBi
? = Wavelength. Unit: meter m.
GM = Mobile station antenna gain. Unit: Decibel with respect to isotropic antenna dBi.
Calculation of adjustment factors
The adjustment factor is calculated as:
where

Online Recruitment Is Here To Stay

Gone are the days when people used to encircle job listings in newspapers and wait for interview calls. Finding a job in India has become so much easier after the web has entered the public domain says RK Sachdeva CEO Tecumseh India Pvt Ltd. He goes on to add that erecruitment has a major role to play in the hiring of a manpower of 2000 which is a part of the Indian branch of this multi national company.

The Wikipedia encyclopedia defines the ‘World Wide Web’ as a global readwrite information space. Indeed it is this space that has enabled us to connect and interact with people across the globe in a matter of a few minutes. Amongst the population of these webusers are a number of employees and employers.

In today’s world of liberalization and globalization the internet provides the workforce with a common platform to interact and communicate. Time plays a very crucial role in the progressive economy and erecruitment ensures that hiring is a convenient process.

TV18 took up a 50 stake in JobStreet.com India which is an online recruitment company. TimesJobs.com which is a part of India’s biggest media house The Times of India broke away from its tie up with Career Builder of the US and has emerged to be the second biggest online recruitment agency. Facts like these establish the point that the Indian workforce is utilizing the web to improve its career prospects.

Employer’s Advantage

Online recruitment is the only medium through which an employer can post a job listing in a few minutes. Responses received are rapid and detailed too. The benefits availed by the employers are various. Employers have the opportunity to provide all the qualifications and characteristics that are necessary for a job. This ensures that only those who are qualified and capable are called for an interview. Right from the initial stages both parties know and specify exactly what they are looking for. Hence the time spent on hiring is reduced by as much as 65. Also in critical situations companies can fulfill their manpower requirements through online recruitment portals.

Jobseeker’s Advantage

The jobseekers too can post their resumes on jobsites and receive quick responses to their job applications. You might be satisfied with your current work situation but you can constantly be a part of the job market and receive updates concerning better options and opportunities. One always has the option of going through the job listings in the mail inbox. The hassle of running around and waiting for interview calls is prevented. You could be sitting in New Delhi and searching for a job in Bangalore or Calcutta. Hence geographical barriers are broken.

Prevention of bias and inequality

After contact is established between an employee and an employer the internet ensures that there is quick exchange of information between them. All the candidates are treated equally and merit is the basis on which a person gets a job. Therefore the process is fair and employees are not victims of personal bias and preferences. Only quality candidates are interviewed through this method. Similarly since there is no regulation on which companies are allowed to post job listings big and small companies are alike and can search for qualified candidates through the same medium.

The preparation of resumes and the posting of jobs the interview calls and the salary negotiationsthe procedure involved in hiring remains the same. The internet just ensures that the process is more efficient and beneficial for both the employees and the employers.

Most importantly this entire process is for free. You do not need to pay any money to post resumes and be a part of the job market. It’s a financially beneficial practice for the employers too.

The Internet and Mobile Association of India conducted a survey on online recruitment and concluded that the number of Indians seeking jobs online is expected to cross 9.2 million in the year 20062007. This signifies that online recruitment is definitely here to stay!

Ten Preparations To Make Before Interviewing

1. First of all know who the company is and what they do. You’ll be asked “Have
you heard of us?” and it is better to be able to respond in the positive. You can
use the Internet to find out something about them. You look unprepared if you
haven’t even taken the time to look them up.

2. Make sure that you can remember what you did on your last few jobs. It doesn’t
look good if you are asked what the project was on a job you worked on recently and
you can’t even remember what the project did or the name of it been there.

3. Study up on the skills that you know that they are looking for. You may well be
questioned or even tested on those skills. Sometimes it’s difficult to remember much
about something you did two years ago but you’re going to have to. You’ll have to
brush up on it again if you hope to get the job.

4. Make sure that you are dressed well but not too flash. A suit is good but a
Rolex watch and big gold rings aren’t. It goes without saying that an opennecked
shirt with your chest hair hanging out will not look good. The same goes for women
with opennecked shirts except for the hair hanging out part.

5. Don’t set out for your interview in a Porsche or a sports car. If you have to
borrow a friend or spouse’s more sedate car. If you’re a contractor you may earn
more money than your prospective boss but don’t shove it in his face.

6. Don’t wait to leave home till five or ten minutes before you have to. You don’t
want to be late. The first rule of salesmen is to never be late. And you are selling
yourself your services and your capabilities. On the other side don’t show up too
early or you may appear too eager.

7. Find out from the agency that sends you if they have sent someone else there for
an interview and ask them to find out what the interview and the interviewers are
like. The agent will be willing to help you even if they have put someone else in.
They are also likely to have spoken to the interviewers and can give you an opinion
on them.

8. If you know someone at the company contact them to get the rundown on the
company and the people interviewing you. If you don’t know anyone you might put out
an email to your contacts to see if they know anyone inside the company.

9. Don’t go out drinking the night before or to a restaurant that has food that
might affect your presence. You’re likely to be nervous and might have had to rush
to get there on time. You never know what is seeping through your pores and into the
interviewer’s nostrils in the small enclosed room where you are being interviewed.
Some nonintrusive aftershave or perfume might be good.

10. Convince yourself that you are the best person for the job and that they will be
lucky to get you. Your confidence will come through. You will get this confidence
through thorough preparation for the interview. There’s nothing more irritating than
failing an interview by not being able to answer something that you should have
known especially if you have been out of work for a while.

Extra tip: Use the Internet to get as much background information as you can.
Remember IBM Sun Microsoft etc all have sites. Don’t do your Internet
investigation the night before the interview. You might find more information than
you can cope with or you may have an ISP problem and get nothing at all.
