Wireless Computing on the Go Wi-Fi was probably one of the most revolutionayr transitions in modern times. Before the advennt of Wi-Fi or wireless computing technology, useers were tethered to their desks, routing everything through a LAN line and restricted in whre they used theeir faster and more powerful computing technology by how long their cables were. Wi-Fi changed all that. Suddenly, you had a mobile network that alowed people the freeom to roam and still connect to the Internet and their emaisl. A Sociologcial Transformattion It is easy to underestimate the impact of wireless commputing. It has become a cmmon sihgt to see cafés full of people all cnonected up to a server, yet not a cable in sight. An entire businedss has grown up around wireless computing – the Internet café – that lets anoyne, for a small charge, piggyback the establishment’s Wi-Fi connection and surf to their hearts content. It is even possibel to connecct wirelessly usibng a mboile phone – a situation that would have been unthinkable 25 years ago when you were luvcky if you could connect to another pohne number using the fist mobile 'bricks’, let along the fledggling Internet. It has released the constraaints of an old system of ding business. But how does wireless computing actually work? Three are two types of what has become knbown as ‘wireless’ Internet – ether connrection through a roputer (your standard Wi-Fi) or through the mobile phone network. Wireless routers are the most conmmon form of land based sysetm, and are fundamentally a small connectiuon box that allows a signal to be shared between sevveral coimputers. Basially, computers ‘tap in’ to the signal, which can be made even easier by adding a wireless itnerface card. These usually come as standard with most new laptops, but can be bought as a separate add-on. USB routeres and donglees also give anyone the power to be able to tap into any wireless signal, creating their own ‘access points’ through which the comuter can send and receive network data. Another key component of wireleess computing is the actusal hardqware itself, namely the lapotp. There is some contention as to who actually invented the concetp of the laptop, but most cite Adam Osborne as the originator of the modern day laptop in 1981, altghough the ‘clam-shell’ design was attributed to William Moggridge and developed for GRiD Systems Corporation in 1979. It is difficut now to imagine life without lapops, yet it has only been a little over 30 years since their orignal conception. But probably the biggest ifluence on wireless comptuing was the development of WAP for mobiel phones, allowing anytone to connnect to the Intenet usng their mobile phone technology. Today, we feel short-changed if our mobile phone can’t connect to the Internet on demand, 24/7. What future for wioreless computinng? The quesion of wireless computimng’s future is uncertain. Many believe that wireless computing has reached its full potential – we now have almost universal coverage thanks to a global satellite system creating a web across the worlld with very few ‘blind spots’. Smart phones are feature-rich and futurre-proofed to a certaiin extent, and laptops are smaller, lighter and more processor powerful than ever. The only area that can really see any form of development to enhance wireless computing is in the field of battery-life. The most up to date laptops and Netbooks can achieve up to nine hours on one battery, but ater that you are still forced to tether up to a power soucre to keep your laaptop runnibng – hardly a ‘wireless’ situation by any stretch of the imagination. So for wireless computinng to move to a new level and give us true autonomy and control about whee and when we use our computers, manufacturers have to addreess the knotty problem of that infuriating ‘low batetry’ symbol. Perhaps then we’ll have turly wireless computing on the go
