Ultra Wideband: Factors to Consider Before You Get Started
The new series of technology is becoming more and more prominent in our society. The introduction of Ultra Wideband (UWB) has revolutionized the way we do things. This technology is used in different types of applications, and can be utilized in a variety of conditions such as strong magnetic fields, high-speed environment, or in harsh conditions.
In the short term, while standards for UWB operation continue to evolve, we will see devices that comply with various aspects of these standards — operating at different power levels and using different transmission modes. It is useful to understand some of the issues raised by UWB operation in order to avoid problems when deploying systems containing UWB devices.
If you are looking to incorporate UWB into your business, here are some factors to consider before embarking on this journey.
Factor #1: UWB Data Transmission Is Highly Susceptible to Interference
UWB works by sending a large number of evenly-spaced pulses over very short time periods. This high density of pulses enables the UWB device to carry more information per unit time than traditional wireless technologies. It also means that in each pulse, there are many opportunities for outside interference sources to jump into the communications channel and corrupt the signal. And since conventional digital receivers can not tolerate any missing or altered bits, it follows that these kinds of random (and generally small) errors can be quite disruptive to UWB systems.
Factor #2: Power Levels Will Affect How Much Interference You See
Based on some studies that have been done with early implementations of UWB across a variety of frequency bands, the amount of interference that UWB can cause to traditional wireless technologies is quite significant — roughly 20 times greater than traditional digital technology when transmitting at equal power levels. Because of this, it is important that UWB devices are operated at the lowest possible power level in order to minimize interference and maximize overall system performance.
Factor #3: Bandwidth Is Another Key Issue To Consider
Interference from UWB comes in the form of energy across a broad portion of the frequency spectrum, and can therefore be difficult to filter out. Since there are frequencies present that are traditionally unused in most commercial wireless devices, this means that an effective tool for mitigating interference is a band pass filter. Some early implementations of UWB have used digital signal processing (DSP) techniques on analog signals at various points in their communication infrastructure as well. In addition to using DSP, some data rates allow signaling with multiple channels in parallel, which helps mitigate the impact of interference further by eliminating any one channel’s contribution when only one or two channels are affected. At least for these bands, a fairly good level of interference rejection can be achieved with dual channel systems (and possibly triple channel in the future) — but at a cost of roughly twice as much digital hardware.
