4 WiFi Protocols Questions and Answers:

1 :: What does ultra wideband (UWB) mean?

Ultra Wideband or UWB is a technique based on transmitting
very-short-duration pulses, often of duration of only
nanoseconds or less, whereby the occupied bandwidth goes to
very large values. This allows it to deliver data rates in
excess of 100 Mbit/s, while using a small amount of power

Applications

Build a home theater environment without cables

Share live multimedia content between televisions

Instantaneously transfer the images from a digital camera
to another product

2 :: How is UWB different from Bluetooth, FireWire and Wi-Fi?

Difference between uwb & bluetooth?
Ultra-wide band wireless radios send short signal pulses
over a broad spectrum. For example, a UWB signal centered
at 5 GHz typically extends acrosws 4 GHz and 6 GHz. The
wide signal allows UWB to commonly support high wireless
data rates of 480 Mbps up to 1.6 Gbps at distances up to a
few meters. At longer distances, UWB data rates drop
considerably.
Bluetooth:/
One way to share wireless high-definition video across a
home network is via UWB connections. As an alternative to
Wi-Fi, UWB's higher bandwidth links can better handle large
volumes of content. Several industry standards for wireless
video streaming compete with UWB including Wireless HD
(WiHD) and Wireless High Definition Interface (WHDI).

Because its radios require low power to operate, UWB
technology can work well in Bluetooth devices. While
Bluetooth 1.0 and 2.0 did not utilize UWB, newer high-speed
versions of Bluetooth may.

The limited range of UWB signals preclude it being used for
direct connections to Internet hotspots. However, some
industry efforts have existed to enable cell phones with
UWB for peer-to-peer applications.

3 :: How to configure Wi-Fi connection and what is wifi protocols?

basically there are many standards of wi-fi in the industry
but some popular of them are 802.11a, 802.11b and 802.11g/n
with the support of these wi-fi protocols we can
cummunicate/interact among the devices at the speed of 5Ghz
to 2.4 Ghz dual band cummunication.

if our wi-fi nic card so firstly we have to install their
drivers and after installation if we have wi-fi access
point then we can see the signal strength in the right
corner below just open that and find the access point to
connect,if A/P is configured with the security,type the key
to connect
