Abstract

A system is provided that can introduce data redundancy into wireless communications, and in particular ultra-wideband (UWB) wireless communications to increase the communication range when transmitting data that has low transmission rates. Multipath degradation, introduced by the extended communications range, can be mitigated by frequency hopping between the orthogonal frequency-division multiplexed symbols of the ultra-wideband waveform. Frequency hopping can place adjacent symbols in different frequency channels for filtering. Data redundancy can be expanded in the time domain and/or the frequency domain, resulting in extended range.

First claim

What is claimed is:

1. A data system comprising:
at least one processor;
a memory storing machine-readable instructions which, when executed by the at least one processor, cause the at least one processor to perform one or more operations, the one or more operations comprising:
selecting a first burst rate for a channel of a wireless network, the channel of the wireless network having a maximum burst rate higher than the first burst rate, the channel configured to at least facilitate communication between a first device and a second device;
determining, at the first device and the second device, a performance information associated with the channel, the performance information including a failure rate of data transmitted between the first device and the second device on the channel;
determining, based on the performance information, whether the channel permits a second burst rate higher than the first burst rate;
selecting, in response to the failure rate being below a threshold value the second burst rate for the channel; and
selecting, in response to the failure rate being above the threshold value, a third burst rate for the channel, the third burst rate being lower than the first burst rate.

2. The system of claim 1 , wherein the first device is a patient care device.

3. The system of claim 2 , wherein the second device is a user device or another patient care device.

4. A method comprising:
selecting a first burst rate for a channel of a wireless network, the channel of the wireless network having a maximum burst rate higher than the first burst rate, the channel configured to at least facilitate communication between a first device and a second device;
determining, at the first device and the second device, a performance information associated with the channel, the performance information including a failure rate of data transmitted between the first device and the second device on the channel;
determining, based on the performance information, whether the channel permits a second burst rate higher than the first burst rate;
selecting, in response to the failure rate being below a threshold value, the second burst rate for the channel; and
selecting, in response to the failure rate being above the threshold value, a third burst rate for the channel, the third burst rate being lower than the first burst rate.

5. The method of claim 4 , wherein the first device is a patient care device.

6. The method of claim 5 , wherein the second device is a user device or another patient care device.
