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. [1] [2]
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.

[11] [12] The brand name UMB (Ultra Mobile Broadband) was introduced in 2006 as a synonym for this standard. [13] UMB was intended to be a fourth-generation technology, which would make it compete with LTE and WiMAX. These technologies use a high bandwidth, low latency, underlying TCP/IP network with high level services such as voice built on ...
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]
Dual-ported video RAM (VRAM) is a dual-ported RAM variant of dynamic RAM (DRAM), which was once commonly used to store the Framebuffer in Graphics card, . Dual-ported RAM allows the CPU to read and write data to memory as if it were a conventional DRAM chip, while adding a second port that reads out data.
Many modern GPUs rely on VRAM. In contrast, a GPU that does not use VRAM, and relies instead on system RAM, is said to have a unified memory architecture, or shared graphics memory. System RAM and VRAM have been segregated due to the bandwidth requirements of GPUs, [2] [3] and to achieve lower latency, since VRAM is physically closer to the GPU ...
Enhanced Voice Services (EVS) is a superwideband speech audio coding standard that was developed for VoLTE and VoNR.It offers up to 20 kHz audio bandwidth and has high robustness to delay jitter and packet losses due to its channel aware coding [1] and improved packet loss concealment. [2]
