H OW TO W R I TE BUSI NESS EM AI LS

BY

FAHIM AZIZ UMRANI

Many of us find it difficult to write emails because we often have to use English which is not our first

language. We specially feel embarrassment when we have to maintain a business communication via emails

e.g., while applying for jobs, requesting information for higher studies etc, the lack of appropriate English

language skills comes in our way. The purpose of this communication is to help those who are not very good

with English language.

I must inform you that to write good emails does not necessarily demand you to be Shakespeare or a

expert of English language. With very little effort and basic skills of English language you can write very desc

emails. For that you just have to keep following Dos and Donts in your mind.

1 . Keep your sentences short.

2 . Always read your email before sending.

3. Do not forget to write appropriate Subject.

4 . Never use all Capital letters, it is considered rude.

5 . Dont forget to use words like "Thank you" and "Please".

For your convenience I am giving you some sample Emails which you can easily reuse according to your nee

Sample 1: Email for Job/ Internship Application.

Hello Mr/Ms. NAME OF PERSON TO BE ADDRESSED, (If you dont know who to address you can just u

plain Hello)

I would like to apply for the post of TITLE OF POST. Please find attached my CV/Resume. Hope to he

soon from you.

Regards,

YOUR NAME

AND CONTACT DETAILS

Sample 2: Email for requesting information for higher Studies.

Hello Mr/Ms. XYZ,

I am interested to apply for Masters/PhD program in your university/College. I

would appreciate if you can help me with the application process. If possible kindly sendthe prospectus and application forms at following address:

WRITE YOUR ADDRESS.

Thanking in anticipation.

Regards,

YOUR NAME

AND CONTACT DETAILS

Sample 3: Email for help in Final year P roject/Mini project.

Hello,

I am final year (or Second year) student of WRITE YOUR DEPARTMENT NAME and

interested to do a project on XYZ (If you are open minded than dont mention any specif

area). Please suggest me guide me with any project proposal.

Thanking in anticipation.

Just keep these sample email in your access and you can reuse them accordin

your needs. Meanwhile continue your efforts to improve your oral and written

guage skills.

If on the other hand when you are writing an email to personal friends or may

sometime to teachers and you have to explain certain thing in your email in d

than dont let your weak English language skills stop you. Tawhan sindhi men

email likhi sagho tha ya agar aap chahen to urdu ya koyee aur zubaan use ke

saktay hen. However, it is not advisable for Business emails.

What is WiMAX?

WiMAX (Worldwide Interoperability for Microwave access) is a standards-basedwireless technology that provides high-throughput broadband connections ovelong distances. WiMAX can be used for a number of applications, including "lasmile" broadband connections, hotspot, cellular backhauls and high-speed enteprise connectivity for businesses.

How does WiMAX differ from Wi-Fi?

WiMAX provides metropolitan area network (MAN) connectivity at speeds of up75 Mb/sec. WiMAX systems can be used to transmit signal for as far as 30 milewhereas Wi-Fi is primarily suited for coverage over small areas. A single basestation can service around a thousand users effectively covering a whole camp

or a small town. Analysts say that Wi-Fi was designed primarily keeping localarea networks in mind, whereas WiMax has been designed for metropolitan arnetworks. As WiMax can support data ranges across miles, it is well suited for country such as India where telecom infrastructure is poor and last mile accesexpensive. This ability enables the ISP players offer broadband access directly homes without worrying about the problems of installing the last mile throughoptic fiber or cables. WiMax is also a big boon for telecom companies as itenables these companies to serve customers in rural areas without spendingbillions used for installing expensive infrastructure for minimal returns.

Expectations

It has the potential to enable millions to access the Internet wirelessly, cheapland easily. The WiMax wireless coverage is measured in square kilometers(miles) while that of WiFi is measured in square meters (yards). A WiMax basestation would beam high-speed Internet connections to homes and businessesa radius of up to 50 km (31 miles); these base stations will eventually cover anentire metropolitan area, making that area into a WMAN and allowing true wireless mobility within it, as opposed to hot-spot hopping required by WiFi. A furtbenefit of the WiMAX standard is that it relies mainly on 2 to 11 GHz bands, asopposed to the overcrowded 2.4 GHz band used by WiFi. The specifications ofWiMAX avoided many of the mistakes that were present into the WiFi standardallowing longer reach, no reliance on line of sight (referred to as Non Line OfSight, or NLOS), greater bandwidth, and better encryption. The 50 km radiusshould be taken with a grain of salt, it would most probably be only applied to true line of sight point to point connection under ideal atmospheric circum-

stances.

WiMAX Technical Information

The IEEE 802.16 Air Interface Standard is truly a state-of-the-art specificationfor fixed broadband wireless access systems employing a point-to-multipoint(PMP) architecture. The initial version was developed with the goal of meetingthe requirements of a vast array of deployment scenarios for BWA systems op-erating between 10 and 66 GHz. As a result, only a subset of the functionalitys needed for typical deployments directed at specific markets. A revision to thebase IEEE 802.16 standard targeting sub 11 GHz has already been completedby July 2004. This revision includes the amendments from Task Group C, TaskGroup A and Task Group D.

The IEEE process stops short of providing conformance standards and testspecifications. In order to ensure interoperability between vendors equipment,the WiMAX technical working groups has completed the work for 10 to 66 GHzand has started working for the sub 11 GHz part of the standard. The workinggroups develop a set of system profiles, Protocol Implementation ConformanceStatement Performa, Test Suite Structure & Test Purposes and Abstract TestSuite specifications for 10 to 66 GHz and sub 11 GHz, all according to the ISO/IEC 9464 series (equivalent to ITU-T x.290 series) of conformance testing stan-dards.

WiMAX Working:

A WiMAX system consists of two parts:

A WiMAX tower, similar in concept to a cell

-phone tower - A single WiMAX tower can pro-vide coverage to a very large area -- as large as3,000 square miles (~8,000 square km).

A WiMAX receiver - The receiver and an-

tenna could be a small box or PCMCIA card,or they could be built into a laptop the wayWiFi access is today.

A WiMAX tower station can connect directly to the Internet using a high-bandwidth, wired connection (for example, a T3 line). It can also connect toanother WiMAX tower using a line-of-sight microwave link. This connection to a

second tower (often referred to as a backhaul), along with the ability of asingle tower to cover up to 3,000 square miles, is what that allows WiMAX toprovide coverage to remote rural areas.

WiMAX actually can provide two forms of wireless service:

There is the non-line-of-sight , WiFi sort of service, where a small antenna on your computer con-

nects to the tower. In this mode, WiMAX uses a lower frequency range -- 2 GHz to 11 GHz (similarto WiFi). Lower-wavelength transmissions are not as easily disrupted by physical obstructions -- theyare better able to diffract, or bend, around obstacles.

There is line-of-sight service, where a fixed dish antenna points straight at the WiMAX tower from

a rooftop or pole. The line-of-sight connection is stronger and more stable, so it's able to send a lot ofdata with fewer errors. Line-of-sight transmissions use higher frequencies, with ranges reaching apossible 66 GHz. At higher frequencies, there is less interference and more bandwidth.

WiMax In PAKISTAN:

Pakistans telecommunication industry - mobile communication in particular - has made impressivestrides in the last few years after deregulation. However broadband growth in the country has beenvery disappointing - there are less than 100,000 broadband users in Pakistan. The open competitionobserved in mobile industry has not been replicated to broadband. Reasons include high prices, controof PTCL over bandwidth resources, policy issues, lack of infrastructure and legal disputes.

With base stations transmitting signals and some equipment at customer location, it promises fastbandwidth for both fixed locations and mobile users. In this backdrop, Pakistan made headlines in2006 when Wateen announced plans to work with Motorola to rollout Mobile WiMAX, the largestnetwork of its kind in the world.

Is WiMAX (Worldw ide Interoperability for Microwave Access) the right technology for develop-

ing countries? In other words,will this new technology deliverthe promise of broadband ataffordable prices?

In Pakistan, the major initiatives include:(1) Wateen - which is using WiMAX solution from Motorola and its cable/fiber network to offer tri-ple play of phone, TV and broadband. Trials have been extended for over a year. Most aggressive tomarket their bundled solutions, they have started advertising without providing pricing and availabilityinformation.

(2) Mobilink - has formed a new entity called Link Dot Net (LDN) to focus on broadband market.WiMAX infrastructure was piloted by Mobilink in 3 cities and a recently issued RFP has generated 7proposals to cover 5 major metros, including in-building coverage for high value business areas. Ma-laysias Dancom, which conducted early trials ofWiMAX in Karachi, was acquired by MobilinksLDN in 2007. Mobilink also bought DV Com and its licenses.(3) Burraq Telecom - which was acquired by ACT consortium which includes Qatar Telecom andClearw ire Corporation, an American operator providing WiMAX services in 10 countries, also plansto offer WiMAX.

The pricing have not been announced by these companies yet. Business users in Pakistan desperatelyneed reliable broadband and are the desired customers because of their high affordability levels. Con-sumer market is different as demand varies by demographics low price is the dominating success fac-tor.

Energy per bit (Eb) is defined as the ratio of signal powerto bit-rate,

Eb = Ps / B [joules / bit],

where Ps is in [watts = joules / sec] and B is in [bits / sec].

The bit-rate can be expressedin terms of the spectral efficiencyb [bits / sec / Hz] and bandwidth W [Hz] required for the signal as

B = b * W [bits / sec].

Therefore

Eb = Ps / (b * W) [joules / bit].

Now note that if the noise is flat with constant power spectraldensity No [watts / Hz = joules], then the noise power Pn inbandwidth W [Hz = 1 / sec] is

Pn = No * W [joules / sec = watts].

Thus the signal-to-noise ratio SNR is

SNR = Ps / Pn = Ps / (No *W),

and Eb / No is related to SNR as

Eb / No = Ps / (b * W * No) = SNR / b [1 / bit].

To state it more heuristically, Eb/No is a sort ofnormalized way to look at SNR in which the SNR is normalizedto the bit rate. For example, you wouldn't want to consider twosignals that have the same SNR to be equivalent (in terms ofenergy efficiency) if one was twice the bit rate of the other.

FIELD TRIPS...

A BETTER WAY TO ENHANCE

KNOWLEDGE

Apart from studies, field trips are one of the best activities for enhancing stu-dents practical approach. It not only increases ones practical knowledge but

also keeps us up to date with latest technologies in demand, improves our

communication skills and builds up confidence level as well, but the condition

is it should be arranged at places which are related to our respective fields

instead of any firm just to make it possible to hang out with fellows.

Students of 07 electronics (section II), arranged a trip to AREA CON-

TROL CENTRE of civil aviation authority, Karachi on 14th of February under

the supervision of our advisor MAM FARZANA RAUFABRO. We were di-

vided into two groups, each headed by their instructor who briefed us about

take off, landing and on way navigation of air planes through radar systems.We got to know about two way communication path (i-e from land to air and

from air to land) and their different frequencies under which pilot and con-

trolling officer communicate. Radar detects every move of planes and Posi-

tion of plane is monitored by officers on a machine called approach and pilot

is informed about every move and coming station in code wordings set by

them. This work is done manually as well so that no chance of mistake is

left. They have four head quarters in lukpass, Quetta, Rahim yar khan & Taf-

tan where radars are fixed.

Although the control system is obsolete and will be renewed very soon

with latest equipments available but the accuracy of controlling air traffic wasremarkable. The best thing I found was that whatever they spoke in control

room was being recorded and saved so in case of any mishap, responsible

should be punished without any queries or hearings. This makes their staff

work more efficiently and keenly.

After getting free from CAA we had lunch and also visited different amuse-

ment places to add fun in trip and have a nice time.

The IEEE (Institute of Electrical and Electronics engineers) is incorporated

in the State of New York, United States. It was formed in 1963 by the merger of

the Institute of Radio Engineers (IRE, founded 1912) and the American

Institute of Electrical Engineers (AIEE, founded 1884). On 1st January 1963,

The AIEE and the IRE merged to form the Institute of Electrical and Electronics

Engineers, or IEEE. It has more than 376,000 members in over 150 countries,

Over 80,000 student members. More than 300 student branch chapters. IEEE

MUET (Mehran University of Engineering & Technology) Student Chapter

started its operations in Jan 2009. Since then, within a period of 2 months or so

it has been actively involved in organizing Seminars and Workshops.

One Such activity was the arrangement of a Guest Lecture on Telecom as aCareer and Bits & bytes for making final year project/thesis, which was

held at the department of Telecommunication Engineering on 7thMarch, 2009.

The worthy guest lecturer was Engineer Sunny Kumar Gemnani, whos a

graduate from Telecommunication Engineering Department, MUET, Jamshoro &

is currently working in Telenor, Pakistan as RF Engineer.

The proceedings started off with the Chairman of Telecommunication

Engineering department, Dr Aftab Memon, welcoming the speaker. A certificate

of appreciation was also presented to the speaker by Dr Aftab for taking outsome of his precious time to deliver a lecture for the final year students of the

department. The certificates were also distributed among Mr. Noman Palijo,

Secretary General, IEEE, MUET Chapter & Mr. Aakash Makhijani, Member of

IEEE, MUET Chapter, for coordinating this guest lecture.

The first session of the lecture was dedicated to the talk on the Final year

thesis/project. The speaker began the talk by highlighting the importance of

thesis/project for an engineering student. Then, the speaker tried to let the

students know what should benefit them more; the thesis or the project? Otherimportant things related to the topic, such as: selection of the topic, role of the

supervisor, basic tools & components for simulations etc, were also discussed by

the speaker in a very effective manner. The session was interactive in the

manner that the speaker involved the students in the discussion & asked their

views & planning about the thesis/project.
