Synchronize data between devices.
Take advantage of wireless printing — send files directly
from your laptop PC to a wireless printer over Wi-Fi

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.
