I am deliberately starting this thread in General Talk rather that Technical Forum

we would do some service to our members who are not too familiar with waht is happening in this field

I am Pasting about Wi-Max and Wi Fi

Hope fully others will add to this thread say what is GSM and CDMA . BLS


Wi-max

WiMAX is a wireless digital communications system, also known as IEEE 802.16, that is intended for wireless "metropolitan area networks". WiMAX can provide broadband wireless access up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations.

Wi-Fi (wireless fidelity)

WiFi/802.11 wireless local area network standard is limited in most cases to 100 - 300 feet (30 - 100 metres). A user with a "Wi-Fi" product can use any brand of access point with any other brand of client hardware that is also Wi-Fi. Any Wi-Fi product using the same radio frequency (for example, 2.4GHz for 802.11b or 11g, 5GHz for 802.11a) will work with any other, even if not "Wi-Fi".

GSM

The Global System for Mobile Communications ( GSM ) is the most popular standard for mobile phones in the world. The GSM standard makes international roaming very common between mobile phone operators , enabling subscribers to use their phones in many parts of the world.
GSM was first introduced in 1991. As of the end of 1997, GSM service was available in more than 100 countries.
In GSM both signaling and speech channels are digital , GSM uses narrowband TDMA , which allows eight simultaneous calls on the same radio frequency. The key advantage of GSM systems has been higher digital voice quality and low cost to making calls such as text messaging.For More Information :

GSM Base Station​
CDMA

Code Division Multiple Access (CDMA) is a "spread spectrum" technology, allowing many users to occupy the same time and frequency allocations in a given band/space. As its name implies, CDMA (Code Division Multiple Access) assigns unique codes to each communication to differentiate it from others in the same spectrum. In a world of finite spectrum resources, CDMA enables many more people to share the airwaves at the same time than do alternative technologies. CDMA communication consists of a Radio Carrier Station (RCS) and a Subscriber Unit.For More Information :

Nanotechnology is the future...

Not sure if Im putting this in the appropriate forum but just felt like.

Nanotechnology:
---------------
Nanotechnology is the engineering of tiny machines — the projected ability to build things from the bottom up inside personal nanofactories (PNs), using techniques and tools being developed today to make complete, highly advanced products. Ultimately, nanotechnology will enable control of matter at the nanometer scale, using mechanochemistry. Shortly after this envisioned molecular machinery is created, it will result in a manufacturing revolution, probably causing severe disruption. It also has serious economic, social, environmental, and military implications.

Neno Tech. very good topic.But if i m not wrong nenotech is at its last stage in wireless designs. i have worked on 45nenometer for NOKIA N95 mobile.Not sure abt future of NenoTech in Wireless.But Semiconductor industry is looking for new techs.
 
Nanotechnology: We've just seen the tip of the iceberg.


I think even in wireless it is still evolving and there is just no saturation point for nanotechnology. I shall provide with some more stronger evidences to support my argument.
1) http://www.nsti.org/news/breaking.html?id=160 : It says $100 million committed capital. Such a huge investment on capital, I feel an economic boom in this technology has just been predicted here. It is dated Jan12, 2007.
2) http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?tp=&arnumber=4283917&isnumber=4283875
Talking about Wireless sensor and actor networks (WSANs). Wireless sensor and actor networks (WSANs) constitute a new pervasive technology and currently one of the most interesting fields of research. Dated: 15-20 July 2007
3) http://www.physorg.com/news114285609.html : Developing tiny wireless sensors. Dated: Nov14,2007
4)

The Nokia N95 is an all-in-one multimedia computer with functionalities that include integrated GPS functionality, 5 megapixel camera and support for high-speed mobile networks. Users can watch and record videos, take high-quality photos, browse the Internet and use the unique 2-way slide to listen to music. But then is that all? Technology is advancing every single day. N95, iPhones are not the end of mobile phones. I am sure much more is still to come. Nanotechnology is here to stay and will stay. Its implementation, in certain fields, obviously would be affected if we talk about morals and ethics.

Not just Information and Communication, the opportunities for nanotechnology are too many in other fields as well: Medicine, chemistry, Energy, Aerospace, Vehicle manufacturing, Consumer goods, etc etc.

I strongly believe that nanotechnology will be everything that we will do in future. You see, no one ever predicted 'internet' to be what it is today. But then, with time there is a change in the way we live.


Thanks,
Sumit
P.S.: Vivek bhai, I think you are very lucky to have worked on 45nanometer for N95 mobile. It is really one 'happening' stuff. :-)

TV SCREENS

Plasma
LCD
Organic LED (OLED)
Surface conduction electron emitter (SED)

Possibly good topics it will also help in deciding one way or other when going to upgrade the conventional CRT TV

Properties of a material changes at the nanoscale and for nanotechnology we do not need to have huge bulk of material!

Some of the other developing technolgies are Quantam Dots, drug delivery devices, man-made skin, nanobandages, nanomedicines, nanosatellites.

Nanotechnology begins with fundamentally with chemistry (how to develop a nanoparticle) and covers every science (depending upon the ultimate application).

Some more of interest BLS

3G (or 3-G ) is short for third-generation technology . It is used in the context of mobile phone standards. The services associated with 3G provide the ability to transfer simultaneously both voice data (a telephone call) and non-voice data (such as downloading information , exchanging email , and instant messaging ).
For more details : http://en.wikipedia.org/wiki/3G

4G (or 4-G ) is short for fourth-generation , the successor wireless access technology to 3G . It is not used consistently, but generally describes several different, but overlapping ideas.
4G technology stands to be the future standard of wireless devices. The Japanese company NTT DoCoMo and Samsung are testing 4G communication at 100 Mbit /s while moving, and 1 Gbit /s while stationary.

I have nothing against the more popular threads , they are equally important and of general interest. However, an awareness of science and technology, what is happening in various fields of interest possibly would help the community to not only benefit from the advances taking place but also would make us aware what is happening around the World.

Sir, can't help really. It all boils down to an individual's own interest. Maybe, they all know all.:)!! But then, I am always game for Science and Technology. Let only a few of us discuss. :) Not a problem. :)

Sir! Awareness comes through sharing! Indeed it is nobel task and let an individual decide if they want to get aware of whatz happening!

It is the lack of awareness that we people suffer for so many odd things!

Best regards!

Sir,

Jatland have a gud history of attention seekers and hence attention payer too. I am watching all this happening since last two years here ( since my membership). We can't help it as our so called NextGen just dwell upon these time pass threads as they can just post one liners there and feel happy instead of discussing something constructive and thoughtful.

I always tried to take part in discussion on every subject in the past .... but after some time almost every thread used to get deflected from the topic. This led to decrease the interests of people who wanted to discuss constructively. They either become silent members or just restricted themselves to limited sections only. Hence, i also restricted myself.

We used to discuss on almost everything.

See an example :

Bluetooth

Source: http://en.wikipedia.org/wiki/Bluetooth
  • Bluetooth provides a way to connect and exchange information between devices such as mobile phones, laptops, PCs, printers, digital cameras, and video game consoles over a secure, globally unlicensed short-range radio frequency.
  • Bluetooth is a standard and communications protocol primarily designed for low power consumption, with a short range (power-class-dependent: 1 meter, 10 meters, 100 meters)[1] based on low-cost transceiver microchips in each device.
  • Bluetooth enables these devices to communicate with each other when they are in range. The devices use a radio communications system, so they do not have to be in line of sight of each other, and can even be in other rooms, as long as the received transmission is powerful enough.

List of applications
More prevalent applications of Bluetooth include:
  • Wireless control of and communication between a mobile phone and a hands-free headset or car kit. This was one of the earliest applications to become popular.
  • Wireless networking between PCs in a confined space and where little bandwidth is required.
  • Wireless communications with PC input and output devices, the most common being the mouse, keyboard and printer.
  • Sending small advertisements from Bluetooth enabled advertising hoardings to other, discoverable, Bluetooth devices.
  • Seventh-generation game consoles—Nintendo Wii[3], Sony PlayStation 3—use Bluetooth for their respective wireless controllers.
  • Dial-up internet access on personal computer or PDA using a data-capable mobile phone as a modem.
  • Receiving commercial advertisements ("spam") via a kiosk, e.g. at a movie theatre or lobby

Bluetooth vs. Wi-Fi in networking
Bluetooth and Wi-Fi have slightly different applications in today's offices, homes, and on the move: setting up networks, printing, or transferring presentations and files from PDAs to computers. Both are versions of unlicensed spread spectrum technology.

Bluetooth differs from Wi-Fi in that the latter provides higher throughput and covers greater distances, but requires more expensive hardware and higher power consumption. They use the same frequency range, but employ different multiplexing schemes. While Bluetooth is a cable replacement for a variety of applications, Wi-Fi is a cable replacement only for local area network access. Bluetooth is often thought of as wireless USB, whereas Wi-Fi is wireless Ethernet, both operating at much lower bandwidth than the cable systems they are trying to replace. However, this analogy is not entirely accurate since any Bluetooth device can, in theory, host any other Bluetooth device—something that is not universal to USB devices, therefore it would resemble more a wireless FireWire.

really a good thred .....

i have an keen interest in all such technologies ....
specially the upcoming ones like ..... WiMax ... .which Brigadier sir mentioned

about nanotechnology in semiconductors ... i guess we are almost at the saturation level .... as we are approaching the wavelength of the electormagnetic waves ... and that is a constraint for signal transmission inside devices .... i guess Vivek can put some light on this ... as i just heard this thing from one of my teacher in college

Plasma TV is also an upcoming thing .... it is available in the market right now .... but its cost is too high for a common person ..... presently i am working on videocons plasma TV logic board .... and our main motive here is to develop a Plasma Display panel which has enhanced picture quality with low price.

i hope this thread goes on and on ....

probably we can discuss about some electronic gadgets as well along with the technology involved in them ..... like the hot mobile phone now a days iPhone ... not yet launched in india ... but it has several features which attracts attention .....

About Plasma TVs i would like to tell that the technology was developed far back in 60s but that requires a lot of data processing .... and at that time we were not having that power ful processors ..... to compute large data on small time .... because we have to meet the minimum frame speed required for the Video display .... that is about 30 frames per second

any one interested can visit the site http://www.howstuffworks.com/ for some details on Plasma ..... of course this site has a good amount of data on almost every technology.
