Presence and IntComm WG

[Peter Day <>]

Here is an excerpt from notes I made during the conference regarding 
my experience of the FMM demo:

Tuesday: Took a while after starting PC, even from having it on and 
opening the top, for it to find the network and connect -- about 30 
secs -- in Ballroom 1. Then wireless connection came and went. At 
first it would say signal strength high, then say it is low. By the 
opening plenary the signal strength in ballroom 5&6 was excellent and 
the network was found immediately on login to the laptop. Then the 
signal strength was low. Speed dropped from 11 mbps to 2 then up to 6.

Signal strength in break room is excellent (Indiana Ballroom). Got an 
immediate connection. Tried to call HelpDesk. When click on name in 
the rich presence portal it is a link of the form sip:. 
If no sip client is open, it tries SIPC and gets errors. Was able to 
connect with helpdesk by initiating call directly from SIPC. I could 
hear the person at the desk, but she said she could hear only static 
and hung up. With session open, clicking on a sip link brought up 
Session call dialog with the address filled in. Attempt to connect 
got dialing message, but no answer. Found that I was connected with 
no signal. Then it said wireless connection unavailable.

Close top, open top, signal strength excellent. The help desk said 
every time I talk they get static and it sounds horrible. Reduced 
volume on microphone to 1/2. When tried to call a room I got "unh is 
unavailable, please leave a message and someone will return your call 
as soon as possible." Then call was terminated.

Helpdesk was using a real IP phone. She turned it on and I tried 
again while sitting next to helpdesk. This time I could not hear her 
on it, even though I was nearby. She said there were two WLANs 
deployed by the hotel, plus rogue access points set to 
infrastructure, plus saw WLAN from AT&T building. Then they decided 
the WLAN system they were using that sent out streams of signals 
instead of clouds was not working and went to classic one and it is 
not working so well either.

Tuesday evening after 9 pm had a better experience. The WLAN strength 
was very good and speed was 6 Mbps. DMM called me using SIPC, which 
he had succeeded in downloading. Both of us were using WLAN and we 
were in the same part of the hall on the second floor. I was using 
Session. His audio was clear, but he said mine was breaking up. I 
switched to SIPC. Then his audio sounded deeper and he could hear me 
OK. We succeeded in adding whiteboard to the session and shared 
browser. We used IM with no problem. Using shared desktop was tricky 
due to issue of SIPC requiring a password and getting some error 
messages on my end. I was using a later version of the SIPC client 
than he was. I experienced breakup of the voice when simultaneously 
using other media.

Wed the signal strength was good and did not drop. Tonight I talked 
with someone on the network team who said the device sending streams 
had been briefly taken out of service then put back again. Still used 
only one stream, but it is a powerful one.
