3 Minutes from April 29 2008 Conference Call
3.1 Agenda
· Attendance (Steve)
· Check to see if anyone is not familiar with the IEEE patent policy
· Presentation on Coexistence Issues for Passive Earth Sensing (Joel Johnson)
· Next Steps
· New business
3.2 Notes
· Joel Johnson presented document 802.19-00/13r0 on Coexistence Issues for Passive Earth Sensing
· SIR for passive earth sensing comes down to the spatial density of the 60 GHz wireless devices and the average EIRP of those devices pointing toward the satellite.
· We need to consider the actual bandwidth of the 802 wireless device versus the 100 MHz bandwidth that was used in the presentation
· Next Steps
- The 802 engineer can review the calculations in this presentation and see if they agree with the calculations
- Joel to check on the satellite antenna gain and report back to the group
· Has anyone made any test using an actual 60 GHz transmitter on the ground?
· There are two or three of these satellites in orbit that use this band
· There are a number of parameters that would need to be considered: gain in the direction of the satellite, the duty cycle of the wireless devices, actual bandwidth.
· Shu Kato will prepare a presentation for next week
· We will have another call on Tuesday May 6 at 8:30 PM EDT (5:30 PM PDT)
