WHAT IS GSM AND 3G TECHNOLOGY?

GSM means Global System for Mobile Communications

In 1982 1G First Generation was introduced where network signals were analogue and used Frequency Division Multiple Access (FDMA)

2G Second Generation was launched in 1992 in which signals and speech channels were digitally encrypted. 2G used Time Division Multiple Access(TDMA)

2.5G Deployed in 2003 which implemented High Speed Circuit Switched Domain(HSCSD) Data rate 236.8kbps to 384kbps by using Enhanced Data Rate for GSM Evolution(EDGE)

3G has very different functions like it allows simultaneous use of speech and data services at higher rates and better spectral efficiency.

3G Standard 

International Mobile Telecommunications IMT-2000 which is popularly known as 3G or 3rd Generation standard for mobile phones and telecommunications services to make 3G globally applicable.

3G UMTS  Universal Mobile Telecommunications System uses W-CDMA WideBand-Code Division Multiple Access as main interface. Also known with other names. In Japan called FOMA Freedom Of Mobile Multimedia Access. In China known as TD-SCDMA Time Division-Synchronous Code Division Multiple Access. Basically all these are variants which uses different radio interface.
W-CDMA networks can give speed upto 384kbps maximum.

3.5G HSUPA upgrades the uplink for higher data transfer speed and capacity of 1.4 ,1.9 ,5.8 Mbps. HSUPA name is given by Nokia and used in its phones only but 3GPP does not support this name.
HSDPA High-Speed Downlink Packet Access having faster speed from 1.8 ,3.6 ,7.2 to 14 Mbps.

3.75G HSPA High Speed Packet Access is a combination of HSUPA and HSDPA that improves the performance of W-CDMA and can attain speed 21Mbps to 28Mbps.

HSDPA High-Speed Downlink Packet Access having faster speed from 1.8 ,3.6 ,7.2 to 14 Mbps.

3.9G HSOPA Some networks dubbed it as 4G. This project is known as Long Term Evolution and uses OF-DMA Orthogonal Frequency-Division Multiplexing which will offer data rate at 170Mbps for up-link and 320Mbps for down-link.

4G Constitute of 4G has not been standardized yet.It is non-backward compatible with new higher frequencies bands. It is defined to be comprehensive and secure for the users. 4G will only be packet-based (all-IP) switched network. Facilities like IP-telephony (IP-based voice data), Ultra-broadband internet Access 1GBps (Gigabit speed) Support for IPV6 protocol, Gaming Services, High Definition HDTV, Streamed Multimedia and many more new services are added!!!

UMTS operates on frequencies of 850/900/1700/1900/2100 MHz. Most 3G phones support at least 2 frequencies. No 3G phone available which supports all 3G frequencies.
It depends on service provider what speed and frequency it adopts for its 3G network and what type of 3G compatible phone you have to fully exploit ,utilize and enjoy the services.

Use Facebook On mobile without Internet connection

Have you thought of using Facebook without Internet on mobile? It would be handy for Facebook users who don’t use Multimedia andGPRS/EDGE/3G enabled mobile phones. People want to use Facebook without data plan, in case if the they don’t have Internet access on mobile.

I remember that I have a good discussion with friends on how to use Facebook on mobile without internet? Now I have a better answer to this question – Yes, you can use Facebook without Internet on your phone. It’s all due to the Facebook India partnership with Fonetwish to bring Facebook on every mobile without any app or data plan usage.

Use Facebook without Data Plan on your Mobile

This new innovative service from Facebook and Fonetwish supports every phone no matter how much old it is. To use Facebook on your phone without Internet in India, just dial *325#(or *fbk#) from it. Dialing *325# on your phone will subscribe you to Fonetwish, which will enable you to access Facebook easily.

After dialing *325#, you’ll receive a display message (just like it appears when we check balance on mobile phones) containing a Welcome message from Facebook (#2).

- If you have registered your mobile number with Facebook, it will automatically show your Facebook Name (#3) followed by enter password message. Just reply or answer this by entering your password. In case you want to login using your email ID, reply with 2 (as shown in the screenshot) which will return a username prompt for you (#4). Reply with your username.

- Next appears the password prompt, reply with your Facebook password (#5).

- After the authentication, it will show up your Facebook Home (#6). You can see options like News Feed, Update Status, Post on Wall, Friend Request, Account Settings etc. preceded by certain numbers and symbols (like 1,2,3..*,#) to perform the particular action. You can see Logout and Notification settings in the Account Settings options by replying with *.

- I chose to update my status by replying with 2, and received “Whats on your mind?” message (#8), I’ve replied with the message I want to put in the status (#9).

With Fonetwish, updating your status is completely free, but using other features, such as posting on a wall, checking notifications, and adding friends is not free. But you can subscribe to it’s unlimited usage with all these features for just Rs. 1 / day. Fonetwish will automatically ask you for this subscription when you try to access the premium features like notifications, post on a wall etc. After subscribing to it’s unlimited usage, you will receive an SMS with the subscription details. You can unsubscribe to it anytime by dialing *322*22#

This service doesn’t have any additional roaming charges, it is available anywhere, anytime! However, you have a limit of 140 characters with this service.

But, this is of course a very handy way to quickly update your Facebook or say in touch with friends – without using Internet. Currently, this service is available for Airtel, Aircel, Idea and Tata Docomo users in India.
