UWB Antennas

Ultra-wideband (UWB) is a short-range, high bandwidth wireless technology which enables applications that require high-speed data transfer or for precise location tracking application. UWB transmits and receives signals across an exceptionally broad frequency range. 

NanoUWB Antenna

The Nano UWB Series antenna is the first antenna which has been designed to operate with the Sera NX040 UWB module. Ultra-wideband (UWB) is a short-range, high bandwidth wireless technology which enables applications that require high-speed data transfer or for precise location tracking application. UWB transmits and receives signals across an exceptionally broad frequency range.

The Ezurio (formerly Laird Connectivity) NanoUWB antenna features a rigid printed circuit board (PCB) that supports UWB implementations. The adhesive backed antenna can be used in space sensitive applications with aesthetically pleasing integration and high durability.

FAQ

How does UWB work?

The functionality of a UWB transmitter revolves around emitting billions of pulses (formerly recognized as "pulse radio") across an expansive frequency spectrum. Subsequently, a corresponding receiver deciphers these pulses into usable data by identifying a recognizable pulse sequence transmitted by the emitter. These pulses are dispatched at a rate of approximately one every two nanoseconds, contributing to UWB's capacity for real-time precision.

UWB exhibits remarkable energy efficiency, while its substantial bandwidth of 500MHz renders it well-suited for transmitting substantial amounts of data from a central device to peripheral ones, covering distances of up to around 30 feet. Nevertheless, unlike Wi-Fi, UWB does not excel in propagating through obstacles such as walls.

What is the difference between UWB anchor and tag?

UWB Anchors have stationary, predetermined positions registered within the positioning system. They receive signals emitted by UWB Tags. Multiple UWB Anchors capture signals from a single UWB Tag. The system records the time it takes for the signal to travel from the Tag to the Anchor (referred to as Time-of-Flight).

What is the difference between GPS and UWB?

GPS functions as a satellite-oriented navigation system, enabling the determination of a lost item's location over extended distances. On the other hand, UWB, a more recent wireless communication technology, utilizes an expansive bandwidth to furnish precise location details for items that have been misplaced in close proximity.

How far can UWB transmit data?

UWB offers a data-transfer capability with an effective range of up to 25 meters, outperforming its competitor Bluetooth technology, which provides an effective range of only approximately 10 meters.

Can UWB go through walls?

The successful implementation of UWB radar technology hinges on how UWB signals propagate through walls. These signals experience not only attenuation but also distortion due to the dispersive characteristics of the walls when passing through them.

What are the downsides of UWB?

UWB's precision is restricted to short distances, imposing a limitation on its capacity to be applied across a wider range of scenarios.

Is UWB the same as WiFi?

UWB systems exhibit the capacity to monitor a greater quantity of tagged assets across extended distances with heightened precision in comparison to Wi-Fi-based systems. While a Wi-Fi-based Real-Time Location System (RTLS) might ascertain the presence of your assets within a designated room, UWB systems excel in providing precise location details within that room for each individual asset.

Is UWB same as Bluetooth?

Ultra-wideband, often referred to as UWB, ultrawide band, or ultraband, constitutes a short-range wireless communication protocol that harnesses radio waves to facilitate seamless device-to-device communication. While bearing a resemblance to Bluetooth, UWB surpasses it in terms of precision, dependability, and efficiency.

What is Fira and do I need to be a member to use UWB?

fira logo

fira is the industry consortium that defines the UWB ranging specification and  certifies products for the purposes of interoperability. The name stands for "fine ranging".
