5. 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:

Easily and quickly receive and transmit files within your local network — no problem
for big files.

Access your email and surf the web with the same speed as that connected with
network cables.

Synchronize data between devices.

Take advantage of wireless printing — send files directly from your laptop PC to a
wireless printer over Wi-Fi connection.
6. 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.
7. 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.
