UWB - Getting DEEPER

---

Ultra Wide Band wireless radios send short signal pulses over a broad spectrum. This means the data is transmitted over a number of frequency channels at once, anything over 500 MHz.

For example, a UWB signal centered at 5 GHz typically extends across 4 GHz and 6 GHz. Although most of the existing UWB devices limited to 6.8 Mbps data rates, the wide signal allows UWB to commonly support high wireless data rates of 480 Mbps up to 1.6 Gbps, at distances up to a few meters. At longer distances, UWB data rates drop considerably.

When compared to the spread spectrum, ultraband's broad spectrum use means that it doesn't interfere with other transmissions in the same frequency band, like narrowband and carrier wave transmissions.

• FCC limits ensure that UWB emission levels are exceedingly small – At or below spurious emission limits for all radios – At or below unintentional emitter limits – Lowest limits ever applied by FCC to any system.

• Part 15 limits equate to –41.25 dBm/MHz – For comparison, PSD limits for 2.4 GHz ISM and 5 GHz UNII bands are 40+ dB higher per MHz • Total emissions over several gigahertz of bandwidth are a small fraction of a milliwatt.

UWB devices can reach range of 100 m - 120 m in ideal scenarios of Line Of Site. Practical indoor solutions usually recommend range of 20 m (and maximum of 30 m) between the sensors (Anchors). The tracked object (Tag) should be within the perimeter of polygon that consist of minimum of 3 Anchors. To achieve better accuracy configuration of 4 Anchors is recommended.
