Wifi technology
WiFi Technology WiFi, stands for Wireless Fidelity and is a term for a high-speed wireless access technology. It is a method of connecting any WiFi equipped device (having built-in WiFi capability or a WiFi adapter card) by radio waves to each other, to a Local Area Network or to the Internet without wires. The only condition is that devices must be within the range of a WiFi signal. WiFi technology uses long range radio waves and the coverage range is sufficiently long.
What is a hot spot is a zone that is enabled with high-speed Wireless internet access HOT-SPOTS are generally available at convenient public locations such as airports, hotels or restaurants. Using either a laptop or a handheld PDA that is WiFi enabled, you can access the Internet ata very high speed. Fact File Bluetooth uses short-range radio frequencies to interconnect electronic devices such as mobile phones, digital cameras and PCs or is made for different applications. It is also slower and works within a short range. On the other hand, WiFi uses long range radio tapes and is seen as an alternative to a wired LAN. It has a wider range and the communication speed is much greater than that of Bluetooth
Wimax technology
Technology WIMAX is a technology standard for long-range wireless networking. WIMAX operates on the same general principles as WiFi-it sends data from one computer to another via radio signals. A computer (either a desktop or a laptop) equipped with WIMAX would receive data from the WIMAX transmitting station. WIMAX stands for World Wide Interoperability for Microwave Access.
The difference between wifi and wimax
The biggest difference between WiFi and Wimax is not speed, but distance. WiFi' s range is about 30 meters, WIMAX can cover an area within a radius of 50 km with wireless access. The increased range is due to the frequencies used and the power of the transmitter. Thus, WiMAX technology will be useful to cover a whole city for Internet access, and which is much more convenient than putting lots of WiFi Hot-Spots in the city
Connecting to the internet on mobile phone
Gone are the days when a mobile phone was used only for "talking anywhere".Now-a-days. more than talking, it is used for playing MP3 music, surfing the Net, sending/receiving e-mails, taking digital pictures, recording videos, mobile conferencing communicating with PCs, etc. Smartphones today have specifications like CPU, RAM, storage space, browsers, email clients. type of display, keyboard, digital camera and its zoom specifications, Infrared (IR), bluetooth and WiFi connectivity. They have almost become miniature versions of computers. You can connect to the Internet using mobile phone, with a GPRS (General Packet Radio Service) or WiFi connection
Using wifi to connect to the internet
A cellphone with a WiFi is capable of using the Net at a very high speed and thus enables you to download large files like big e-mail attachments, music files, etc Doing this over GPRS can be a time consuming process because of not so high a speed. Also you do not have to pay any GPRS charges while surfing the Net using WiFi access. You just need to be at a Hot-Spot to be within the range of WiFi signals
Mobile broadband Mobile broadband is a general term used to describe high speed internet access from mobile service providers (like Airtel, Vodaphone, Idea, etc) for portable devices like mobile phones and tablets. If you have a data plan to access internet from your mobile phone using your cellular provider's 3G or 4G network, that's mobile broadband.
3G/4G mobile braodhand technology
3G/4G Mobile Broadband Technology 3rd generation (3G) networks enable network operators to offer users a wide range of more advanced services like wide area wireless voice telephony, video calls and broadband wireless data, all in a mobile environment 3G is considered a high-speed or broadband mobile Internet access, and in future the 3G networks are expected to reach speeds of more than 2Mbps. 4GA Quiz If you have to try wires and access in a mobile environment dib ay will you prefer and why? Latest Trends The 4G network have very standards of speed (may be times faster then 3G) and connectivity to enhance uv communication and connection reliability.
Connecting your pc to 3G/4G Mobile broadband Mobile Broadband You can buy a 3G or 4G USB modem (dongle) which will fit in USb port of PC and for the decided data plan and service charges, you can co the Internet. Tata Photon, reliance, Airtel are some companies which provide
