What is the alternative for ADSL broadband?
What is Wireless Broadband ?
Wireless broadband is a general term used for the technology that is able to gain access to the INTERNET wirelessly, and at high bandwidth speeds.
What is the technology behind wireless broadband services?
Wireless broadband is available on virtually any digital device, so long as it has the proper connectivity hardware. Such hardware can easily be attached to most PDAs and laptop computers.

For now we have 3 options.(In some country ,it might be more.)

1.3G

2.Wi-Fi

3.Wimax

What is 3G?

The term 3G refers to the third generation of mobile phone standards as set by the International Telecommunications Union (ITU). 3G technologies allow mobile operators to offer more options to their users, such options include mobile broadband.As a technology, 3G facilitates devices such as mobile phones and mobile dongles to deliver broadband speed internet.

Most new top of the range mobile phones are 3G enabled, making it easy to check emails and browse the web on the go.These technologies enable mobile broadband users to access of up to 7.2Mb speed downloads and uploads with speeds of up to 1.7Mb via a mobile dongle, USB modem or data card which they plug into the USB port of their laptop or PC.

What is Wi_Fi?

One of the most popular and well known wireless technology standards is Wi-Fi (Wireless Fidelity), which allows users to access the internet over a wireless Local Area Network. The speed and range of Wi-Fi, however, is severely limited. There is another wireless connectivity standard, called Wimax , which is considerably more advanced..


What is WiMAX?
WiMAX is a protocol by which signals are sent to wireless broadband users. A WiMAX base station can theoretically beam a signal as far as 50km (31 miles), meaning that a single station could potentially cover an entire city (unlike Wi-Fi, which is only available in "hotspots").The cons for WiMAX is the base stations are very expensive to build, and arent cost effective in less densely populated areas. Because of this limitation, WiMAX technology is not yet available in most non-urban regions.

The Further of Wireless Broadband technology.
Even though WiMAX has been a major technological achievement, wireless broadband certainly doesn't stop there. There are a number of other cutting edge wireless protocols currently in development. The most notable of these is a new protocol called xMax, which is similar to WiMAX, but a lot more efficient. It can cover a broader range at a lower cost, by piggybacking on radio frequencies.

Although xMax is not yet available to the public, it will most likely be launched within the next couple of years.3G is one of the most popular options now.With a laptop with built-in 3G broadband you get the best of both worlds. Whether you're in the back of a cab or waiting at the airport, a pre-installed 3G broadband gives you fast, secure access.







P/s:Local surfer,If you live in Klang Valley and you are not satisfied with Streamyx ADSL broadband service because they just didn't provided affection service to user ,you can go P1 w1max Wireless or the latest YES 4G mobile broadband
