Open the CIPO recordAbstract From the Canadian patent
A system and method for frequency planning in a wireless communication network area using an impact matrix (50) which relates signal interference impacts between sectors (54, 58) in a network service area for co-channel and adjacent channel interference. The impact matrix (50) uses weighted propagation analysis (60) and empirical measurement data (62) to determine signal levels within each pixel of a network service area. The system merges the propagation analysis (60) and empirical measurement data (62) according to user assigned confidences.

Why it's free to use
- Filed August 9, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 9, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 9, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
