Tips for Wi-Fi users
With a Wi-Fi connection, you can roam about 150 m around the access point (depends on different environment), so find a spot where you can work without any interruption. Then see how much
work you can do, such as:
z Easily and quickly receive and transmit files within your local network — no problem for big files.
z Access your email and surf the web with the same speed as that connected with network cables.
z Synchronize data between devices.
z Take advantage of wireless printing — send files directly from your laptop PC to a wireless printer over Wi-Fi connection.
Warning
Wi-Fi offers greater speed and range than Bluetooth, but it drains your portable device batteries a lot faster than Bluetooth does. In fact, if you use a Wi-Fi connection regularly on your laptop PC,
you'll undoubtedly notice that you need to recharge more often. If you need to conserve battery life — on a long trip for example — turn off your Wi-Fi connection when you don't actually need it.
Security
Because wireless networks rely on radio signals to transmit data, they are not as secure as wire network. Wireless networks are susceptible to viruses and breaches like eavesdropping and need to
be protected in order to be secure.
There are many security measures to safeguard wireless networks, protect the data, and keep unauthorized users out. Hotspots, on the other hand, are often free of standard security practices in
an effort to make it easy for anyone to connect. It may be found that some pay hotspots administered by service providers offer have some level of security, however, when using a hotspot, it’s
always a good idea to be proactive and to employ security measures of your own.
Key terms
Wi-Fi: Short for “wireless fidelity,” a generic label that refers to wireless networks or networking.
Hotspot: A specific geographic location in which an access point provides public wireless broadband network services to mobile visitors through a WLAN.
Throughput: The amount of data transmitted in a set amount of time.
Bandwidth: the amount of data that can be carried from one point to another in a given time period (usually a second).
Chipset: A group of microchips that execute various functions (like memory) to support the CPU.
