Open the CIPO recordAbstract From the Canadian patent
A mobile wireless terminal (MWT) includes multiple wireless modems. The multiple modems have their respective transmit outputs combined together to produce an aggregate transmit output. The multiple modems can concurrently transmit data in a reverse link direction and receive data in a forward link direction. The MWT is constrained to operate under an aggregate transmit power limit. Each of the multiple modems has an individual transmit limit related to the aggregate transmit power limit. An MWT controller adjusts the individual transmit power limits in the multiple modems based on an aggregate transmit power limit of the MWT and respective transmit power estimates from the modems, …

Why it's free to use
- Filed October 29, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 29, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 29, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
