An Epic Journey

Just one more day of school. Wishing myself good luck, I begin my journey. My school, Don Bosco School Liluah, is situated in Liluah, which is a five kilometres’ journey from Howrah Railway Station. Howrah is located in West Bengal of India.

Crossing the stretch of no man’s land, from Howrah to Liluah, is not merely a journey; it’s more of an adventure sport. And, travelling in an auto rickshaw augments the adventure. I belong to those fortunate fools to avail this ‘devil’s own’ mode of transport to reach my school, twice every day, five days a week. It is an epic journey every day.

Looking Down At Myself

This was written years ago, on my eighteenth birthday. (I intended to respect myself and not make any modification to the original script.)


When I look up at the sky, I see not any stars;
Nor do I see any planet, moon, cloud, neither any comet.

What I see are faces.

Faces, looking down at me, speaking to me and calling me…
Every face forms a star; and every star — a face.

Weird faces!
Some laugh, some cry, some mock
And the rest haunt.
Some of the faces are known when some of them are strangers
I know those strangers. Don’t I?

Life Again

Today I woke up
And things happened!

Soon, I’ll go to sleep, dream
And try to ammend.

Tomorrow I’ll again awake
And more things will happen.

Again I’ll go back to sleep and dream.
So, what does one recommend?

The demise of FDMA cellular transceiving technology

As of today (September 9, 2002) there are three main cellular technologies: Older analog FDMA (Frequency Division Multiple Access), modern GSM TDMA (Time Division Multiple Access) and Newer CDMA (Code Division Multiple Access.) People mostly know of the latter two and the first one is almost wiped off from the history of Cellular Network technology.

I am not going too deep into the technical aspect of all the networks and am just giving an outline of FDMA.

Analog transmission is considered an “older” cellular phone technology. Back in the early 198o’s, it was the first network technology to be deployed successfully. FDMA is used exclusively for analog cellular systems, even though in theory FDMA can also be used with digital networks.
Essentially, FDMA splits the allocated spectrum into many ‘channels,’ each of approx 30 kHz bandwidth. During a data transfer, in form of audio or video, an FDMA networks allocates the entire channel to the phone and the data is modulated into this channel’s frequency band and sent over airwaves. At the receiver’s end, the information is recovered using a simple band-pass filter. The phone then uses common control-channel function to acquire channels during Handoffs1.
