What Are Wireless
Adapters and How
Do They Work?
Wireless adapters are electronic devices
that allow computers to connect to the
Internet and to other computers without
using wires.
They work by sending data through radio
waves to routers which pass the data on to
broadband modems or internal networks.

What Types Of Adapters Are
There?
The most common type of adapter is the kind that is
already built into the device. However, a lot of older
computers and devices without a built-in wireless
adapter must rely on wireless cards in order to access
a wireless connection.
For a desktop computer, there are two types of
adapters; one that plugs into a PCI slot inside the
computer case and one that plugs into a USB port
from the outside.
For laptops without built-in wireless connectivity,
there are wireless adapting cards to fit into either the
PCMCIA slot or the PCI slot.
For tablets and notebooks, there are cards that can
be inserted into the memory card slot.

What Are Wireless
Standards?
Wireless standards are the standards which
determine the speed of data transfer at
which wireless adapters broadcast.
Radio waves used by wireless adapters
must satisfy one of the 802.11 broadcast
standards of the IEEE.

How Fast Are Wireless
Adapters?
With the oldest wireless standard, IEEE 802.11b,
broadcast speeds are specified to be up to 11 Mbps.
The later model wireless adapters, which broadcast at
IEEE 802.11g, can reach speeds that can reach up to
54 Mbps.
With the IEEE 802.11n standard, wireless adapters
can theoretically reach speeds of up to 300 Mbps,
however, since the radio frequencies are crowded and
there is interference, the adapters using this standard
are generally slower.
With the IEEE 802.11ac standard, wireless adapters
will be able to theoretically achieve speeds of up to 1
Gbps because this standard will be able to operate in
the 5GHz frequency band.

How Do Wireless
Adapters Keep Your
Information Secure?
Since wireless adapters broadcast signals
from devices with a range of around 200
feet, anyone with a wireless adapter could
potentially pick up one's signals and access
their files.
To prevent this, wireless adapters use
encryption protocols to keep their signals
secure. These protocols are WEP, WPA,
and WPA2 and they offer password-
protected and encrypted transmissions for
wireless networks.
