2. IEEE Work Plan
Generated a response to ECC WG SE24 on use of 5 GHz onboard aircraft
Heard an update on EN changes for v1.8.1
Final review of inputs to IMT-Advanced (editorial changes only)
Re-edited the input to M.1450; updates for new amendments caused document formatting errors
Reviewed “ITU Mark” proposal
Start looking at a response to the TVWS R&O

3. Weather Radars and 5 GHz RLANs
EUMETNET is claiming (erroneously) that DFS does not work, and that 5 GHz RLANs must be banned from aircraft (and possibly all mobile platforms)
Claim that mobile platforms cannot meet new CAC requirements
Mobile radars are protected by In Service Monitoring; CAC not relevant
Want to block 5600 – 5650 MHz band; could be extended to full 5250 – 5350 and 5470 – 5725 MHz bands
Issues seen appear to have been with non-compliant, high-power APs
Boeing has performed field test; data show no impact on weather radar operation
Letter asks SE24 to consider test data, and that RLAN community be involved in any future decisions on this matter
