Open the CIPO recordAbstract From the Canadian patent
An end-to-end system for transmitting and receiving non-voice data such as for example, facsimile and voice data over a wireless link. The end-to-end system comprises a first station and a second station. The first station processes facsimile data and voice data for transmission over the wireless link. As the facsimile and data signals have different transmission rate and bandwidth requirements, the first station segments or splits facsimile data such that facsimile and voice data are properly multiplexed over the wireless link without distortion. The second station may adapt with the first station for receiving and transmitting facsimile and voice data via the wireless link.

Why it's free to use
- Filed July 26, 2000 and granted February 8, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 26, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 26, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
