Mr. Mai Quoc Khanh, lecturer of Military Technical Academy, does not have the habit of Wi-fi cafe surfing. His office has wi-fi Internet and home also "wireless". In the home there is a laptop, two desktop computers, an O2, an iPaq and all become "synchronized" in the wifi space that he wants to create.

Nguyen Viet Ha, Deputy Director of a trading and service company, revealed on Handheldvn.com forum: " I have a special interest in the wireless network and therefore have brought wi-fi home from 2 years ago ".

According to Mr. Khanh, Mr. Ha, there is no big difference in investment costs for home Wi-Fi compared to normal ADSL installation. So why not reduce the mess in the house by making anywhere in the house accessible to the Internet by connecting wi-fi?

Mobile elements, want to move in the house, can network when sitting anywhere is a common reason for Mr. Ha, Mr. Khanh "links" wi-fi. Currently, when there is no wimax, wi-fi is the best choice to help create this convenience.

Wi-fi ( Wireless Fidelity ) is generally understood to be a form of wireless Internet connection. With the wifi application, we can connect to the Internet wherever you are at home, at the company, at Internet cafes, in hotels, airports . if there is an 'access point' (hotspot).

Wireless technology was born in June 2003, and is widely deployed in underdeveloped and developing countries, especially in African countries. Advantages: Low-cost terminal, high efficiency. Disadvantages: if out of the 'coverage area' (about 100m) of the hotspot, the communication will be broken immediately.

Many experts believe that Worldwide Interoperability for Microwave Access, which is being deployed in the world today with wider coverage, will overcome this disadvantage of wifi.

Home Wi-Fi users also have to invest in only a few devices that are becoming more and more familiar. It is a wi-fi network card (if the computer is not already integrated) and an ADSL modem that supports the wireless function as an Access Point (costing about US $ 100-150) to connect to the ADSL line of the Internet service provider.

" Another reason is that I love technology, teaching telecommunications networks and network security, so I want to take advantage of the wireless network, take home wi-fi, and use it while I study. Imagine, I can move anywhere in my house with a laptop that can work in an online environment, so convenient, so many of my students also use this form . ", Mr. Khanh shared .

Mr. Ha said the bad thing about using wi-fi is that it is less secure than the network in the usual way because it is very likely to be hacked during the connection process, "however," convenience is still more overwhelming. "

Mr. Khanh does not worry about security factors because the current wireless network devices have certain security features, can install themselves. Mr. Khanh said " if your neighbors use their" temple, it will not cost much and you do not always turn on the wi-fi connection at home ".

Mr. Khanh uses a family package with unlimited usage. The dissatisfaction, if any, at home wi-fi with Mr. Khanh is "getting better or worse than using conventional ADSL". However, wi-fi is still the best solution for him to transfer files, install from desktops to laptops, PDAs with computers . in a convenient, synchronous way.

Mobile or will it be replaced?

Using wi-fi at home is an inevitable trend and when asked, many laptop users expressed this need. This is the synchronization when the number of laptops is increasing and the technology also lifts from dial - up to high - speed Internet (ADSL) and wireless wi - fi.

Laptops, personal digital assistants are getting more and more popular, and the trend of getting access to wireless Internet is increasingly common.

Rising home hotspots have added "wireless realms" that have sprung up like mushrooms in office buildings and especially luxurious cafes. The race to open wifi cafe and be described as a place for young people "stylish" will no longer be "fashionable" anymore. Obviously, when accessing the wireless Internet at home, it will be more convenient and less expensive than the inn with the additional "extra" fee.

But whether home Wi-Fi and Wi-Fi are at risk of wimax (not too long will be available in Vietnam) to "nock out"? Mr. Ha said that "wi-fi will not" retire young "when wimax is available." "Wixax cannot replace wi-fi" is Mr. Khanh's judgment. Because " In environments such as work or home, the network connection via wireless LAN is still more effective. Using the indoor computer, the distance of wi-fi coverage is 100 meters still guaranteed ".

Thus, the continuous development of technology has helped erase the separation, contributing to the trend of pursuing "digital life". Some people say that when they attach themselves to technology, such as cell phones, networked computers, we seem to be more mobile, more free but actually are bound. Connecting with those things means that we are always under the control of others. There are times when sometimes we have to turn off the modem, get off the Internet to "escape", look for fewer minutes of freedom, so as not to be noticed by others (?!).

However, those who use wi-fi Internet, which is online often that we have met, consider it a way to "not be more entangled, more autonomous". So high technology adds or restricts human freedom ?!

It seems that the story of wi-fi returns to having technology as one thing, how we exploit and use it most effectively is another matter. Running and updating new technology will not make sense if it is just to make and show off.
