2. CWPAN Plenary Meeting (Dec 14, 2007)
<month year>
doc.: IEEE <doc#>
Mar. 2008
CWPAN Plenary Meeting (Dec 14, 2007)
Review the Standard and R&D works (Low-Rate and High-Rate) on behalf of CWPAN working group in 2007
Discuss the issues on IEEE C Atlanta meeting.
Set up the working plans for 2008

3. Discuss the PHY solution of LR-CWPAN
Mar. 2008
Discuss the PHY solution of LR-CWPAN
On Dec 14, 2007, most of semiconductor companies in CWPAN discuss the PHY solution at 780MHz in LR-CWPAN std.
Important Suggestion are:
It is possible to adopt the MPSK and OQPSK as the co-alternative PHY solution at 780Mhz in LR-CWPAN std.
Working group should tell WPAN users and chip manufacture clearly. It is their responsibility to support the WPAN with MPSK or OQPSK adaptively

4. The Short Minutes of CWPAN working meeting on Jan 08

The Short Minutes of CWPAN working meeting on Jan 08
The main purpose of the meeting was to review the security tech proposal and comments about the present security algorithm and procedure in the Chinese LR-WPAN standard (draft).
The major solutions from these discussion are:
LR-WPAN Standard does not give any description about the security application on NWK. Any related (NWK) security proposals would be discussed on Wireless Sensor Networks Std task group.
AES algorithm is finally suggested as the commercial security algorithm. However, JiaTon company may suggest other algorithms: SHA256 and ECDH algorithm (recommend by National Security Key Management Bureau), for optional security algorithm, being used for the special applications.
JiaTon is in charge of discussing this optional algorithm with National Security Key Management Bureau. If getting their permission, Jiatao may give the further proposals to CWPAM conference.

5. CWPAN Plenary Meeting (March 08)
Make the conclusion for PHY solution of LR-WPAN std
Answer the questions for LR-CWPAN std (D1)
Discussion the tech proposals for HR-CWPAN std

6. Summary of PHY Solution of CWPAN on March 08 Meeting
The MPSK and OQPSK (modulation and coding) proposals  are adopted as the co-alternative PHY solution of “The PHY and MAC layer Specifications of  Low-Rate Wireless Personal Area  Networks” (Task No: T-469)  at Chinese 780Mhz operation frequency band (779 – 787 MHz). 
Here, the Co-Alternative Solution is defined as:
Or, the MPSK (modulation + Coding) tech proposal is adopted as the PHY solution of  (Chinese) LR-WPAN standard body individually;
Or, the OQPSK (modulation + Coding) tech proposal is adopted as the PHY solution of  (Chinese) LR-WPAN standard body individually;
Or, the MPSK and OQPSK (modulation + Coding) tech proposal are adopted as the PHY solution of (Chinese) LR-WPAN standard body together.

8. Schedule for LR-WPAN (PHY and MAC Spec) std
Mar. 2008
Schedule for LR-WPAN (PHY and MAC Spec) std
March 2008, D1 was reviewed and all of questions were answered from first letter ballet members
May 2008, D2 will be reviewed and all of questions are answered from second letter ballet among the CWPAN members
July 2008, draft of LR-WAPN is goring to be reviewed by expertise, and companies.
Sept 2008, draft of LR-WPAN makes the last modification.
Oct 2008, the draft of LR-WPAN is submitted to approval
Expect the LR-WPAN (PHY and MAC spec) std may be done around end of 2008.
