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.
