IEEE 802.15.4 HRP UWB
|
High pulse repetition frequency ultra-wideband (HPR UWB) is one of the physical layers defined for low data rate personal area network (LR-WPAN) communications in the IEEE 802.15.4 standard.
According to the FiRa Consortium:
"In challenging environments, such as parking structures, hospitals, airports and high density venues, ultra-wideband (UWB) technology outperforms other technologies in terms of accuracy, power consumption, robustness in wireless connectivity, and security, by a wide margin.
"UWB securely determines the relative position of peer devices with a very high degree of accuracy and can operate with line of sight at up to 200 meters. In contrast to narrow band wireless technologies, the use of wide bandwidth means UWB provides very stable connectivity, with little to no interference and offers highly precise positioning, even in congested multi-path signal environments.
"By calculating precise location, fine ranging based on UWB is a more secure approach to closing and opening locks, whether those locks are installed on a car door, a warehouse entryway, a conference room, or your front door."

PAVE PAWS
|
According to the U.S. Space Force:
"PAVE Phased Array Warning System (PAWS) Radars are maintained by the U.S. Space Force. These radars are capable of detecting Submarine Launched Ballistic Missile (SLBM) attacks and conducting general space surveillance and satellite tracking. PAVE is a military program identification code.
"The PAVE PAWS are ground based phased array radars located on the west and east coasts of the U.S.
"Missile warning and attack characterization data is sent to the U.S. Missile Warning and Space Control Centers, the U.S. National Military Command Center and U.S. Strategic Command. Satellite tracking data is sent to the Combined Space Operations Center (CSpOC) for processing."
PAVE PAWS is a high-power phased array radar operated by the U.S. military to detect intercontinental ballistic missiles. There are presently (2024) three operating PAVE PAWS sites at Clear, AK, Cape Cod, MA, and Beale AFB, CA. The PAVE PAWS radar is also known by its government designator, AN/FPS-115.
According to the spec sheet at the fas.org Web site, PAVE PAWS has a peak/average transmit power of 582/146 kW, antenna gain of 38 dBi, and an operational range of 3,000 nm (about 5500 km).
PAVE PAWS radars are also capable of detecting echoes off of Earth-orbiting space debris.
