    en.wikipedia.org/wiki/List_of_UWB_channels

    Within a single band group, the maximum number of non-overlapping channels is actually three. Any time two devices are transmitting at the same frequency and within radio range (<10m), regardless of their logical channel they will either look like noise to each other or must logically share the timeslots in the channel.

    Ultra-wideband (UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. The following is a list of devices that support the technology from various UWB silicon providers.

    The FiRa Consortium (FiRa – "fine ranging" [2]) is a non-profit organization that promotes the use of ultra-wideband technology for use cases such as access control, location-based services, and device-to-device services. [3] UWB offers fine ranging and secure capabilities and operates in the available 6–9 GHz spectrum. [4]

    en.wikipedia.org/wiki/Base_curve_radius

    Base curve radius (BCR) or simply base curve (BC) is the measure of an important parameter of a lens in optometry. On a spectacle lens , it is the flatter curvature of the front surface. On a contact lens it is the curvature of the back surface and is sometimes referred to as the back central optic radius ( BCOR ).

    AMR-WB is codified as G.722.2, an ITU-T standard speech codec, formally known as Wideband coding of speech at around 16 kbit/s using Adaptive Multi-Rate Wideband (AMR-WB). G.722.2 AMR-WB is the same codec as the 3GPP AMR-WB. The corresponding 3GPP specifications are TS 26.190 for the speech codec [3] and TS 26.194 for the Voice Activity ...
