Band Uses (9.5 - 9.9 GHz)

TerraSAR-X

TerraSAR-X is an X-band German Synthetic Aperture Radar (SAR) satellite that can provide imaging resolution down to 1 m at any time of the day or night and regardless of weather. The satellite was launched on June 15, 2007, and became fully operational on January 7, 2008. TerrSAR-X is in a 514 km altitude nearly-polar orbit (97.44 deg inclination circular orbit).

The peak radiated power of the SAR emissions is 2260 W, linearly polarized. The pulse repetition rate is 2.2 - 6.5 kHz. The repeat time to appear at the same point on Earth is 11 days, but including beam coverage, the signal can be seen as frequently as every 2.5 days at a given spot on Earth.

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."

Possible extension of EESS (active) allocation (WRC-15 Agenda Item 1.12)

ITU World Radiocommunication Conference 2015 Agenda Item 1.12:

"To consider an extension of the current worldwide allocation to the Earth exploration-satellite service (active) in the frequency band 9300-9900 MHz by up to 600 MHz within the frequency bands 8700-9300 and/or 9900-10500 MHz, in accordance with Resolution 651 (WRC-12)"
