The Whys and Wherefores of Wi-Fi
Not long ago, Wi-Fi technology was only available at certain businesses and in a few homes. But now it is virtually everywhere – in airports, hotels, bars, restaurants, many residential communities and even government institutions. Such rapid advancement indicates that Wi-Fi will soon become commonplace in most populated areas across the country, making it a subject of interest to many homeowners.
what exactly is wi-fi?
Wi-Fi means “wireless-fidelity” and is a term registered by a non-profit group known as Wi-Fi Alliance. The organization promotes international standards for wireless technology and certifies products that comply with those standards. Wi-Fi technology allows a portable computer that is being used in multiple locations to access remote information without having to be continually unplugged and plugged in again at the next location. To accomplish this, the computer requires a rechargeable battery to maintain power, and a built-in Wi-Fi signal receiver, commonly known as a “wireless card”, to access the internet.
Wi-Fi became very useful for office workers who needed to retrieve company files while attending frequent meetings in different parts of a building. Quickly, the desire for email and internet connectivity from various locations developed. Now almost all new laptops are Wi-Fi enabled. Even those previously unfamiliar with wireless computing could see the convenience of internet availability on any computer, anywhere in the house.
does wi-fi offer affordable value?
Many municipalities across North America are setting up Wi-Fi networks to transmit internet signals, or “hot spots”, from streetlight poles. Establishing a Wi-Fi infrastructure will allow interconnectivity with taxpayers and provides and opportunity for many cost advantages. For example, household utility usage could be determined without sending employees out to read meters. Some communities are actually offering wireless connectivity at no charge, at least until maintenance costs can be determined. So, depending on where you live, Wi-Fi could mean drastically reduced fees for broadband internet service, and much greater convenience.
what are the benefits of wi-fi?
Clearly, non-business use of computers is increasing, as more and more people use the internet to stay in touch with one another – making plans, engaging in conversation and sharing photographs on-line. As computers become even more mobile, making he more internet accessible will become a priority. As a result, it will be easier to find a recipe, or check out a movie time from anywhere… as your computer and internet access could always be with you. The more accessible Wi-Fi becomes, the more likely people will be to bring laptops with them during extended personal time – even on vacation. Although some people will be taking work home, or even away on weekend, at least the Wi-Fi technology will let them be with their families rather than in their offices.
will wi-fi change the way we live?
As computers and hand-held devices get smaller, we will have instant access to a phone book, dictionary, encyclopedia, map, newspaper, radio, TV, interactive game device, CD and DVD wherever we go! Already, cell phones are equipped with Wi-Fi accessibility because it is cheaper to download data-rich visuals via Wi-Fi technology than to use cellular transmission. Inexpensive (or free) voice transmission will surely become one of Wi-Fi’s most popular benefits – something obvious to those who use the latest personal digital assistants (PDAs), which combine the portability of a cell phone with the information and entertainment value of an online computer. Surveys indicate that the majority of current Wi-Fi users believe they are now more productive at work, in school, at home and during travel. It has even been suggested that relationships can improve because Wi-Fi frees up more time to spend with family and friends, and offers expanded opportunities to stay in touch.
how will wi-fi be used in the future?
Imagine downloading your text and phone messages, getting an audio version of your favorite daily journal report, and booking a maintenance appointment with your auto dealer all while standing in line at the grocery store. Wi-Fi technology is quickly getting there , and it’s becoming faster, cheaper and smaller. So it’s no stretch to imagine new appliances, tools and toys with the capacity to exchange data online from anywhere. You’ll be able to take photographs or video images, then instantly email them without processing or downloading. Or you might get an instant discount from your favorite retailer, just because you’re driving nearby!
preparing for wi-fi today
If you get a Wi-Fi enabled laptop, you’ll need to confirm the source of y9our Wi-Fi signal. At home, your internet service provider (ISP) will likely suggest you purchase or rent a wireless modem. You may want to shop around before choosing. When mobile, Wi-Fi signals can be more suspect, unless you are in a hot spot provided by a reputable chain store, hotel or airport authority. So it’s wise to learn from the outset how to verify your signal reception. Also, remember to keep your passwords secure. Meanwhile, the Wi-Fi industry is already preparing the next generation to include WMMa (wireless multi-media) and something called Wi-MAX – ready or not, here it comes!
