[asterisk-biz] ITU - Amazing Finds

[Senad Jordanovic]

Hi Nick
 
We had a switch installation in Spain which used exclusively below solution.
Accordingly to the customer, UK guys came over, installed few base stations
(and I am talking the full works here including the towers on top
of the hills), collected thousands of euros and left.
 
Since then, the stability of the wireless network was, well to put it
mildly, not up to any acceptable commercial standard.
I have personally experienced: (lets get to tower, it needs rebooting) :)
and customers calling complaining about QoS (while barely able to hear them)
 
Customer also had since then deployed another wireless solution, and had not
a single issue. Works perfectly.
 
I am not trying to start flames here... just need facts.
Why would that be the case? Why would a mesh network not perform?
What factors does it get influenced by? Etc...
 
 
 
Regards,
 
 
Senad

If you want open source for mobile ad hoc networks (manets), you might try
looking at http://www.olsrd.org <http://www.olsrd.org/> 

 

I have been following them for a few years and the software is maturing
nicely.  Since source is available, you can cross compile and put it on a
WRT54G or other linux router with asterisk also installed on the router.  It
is based on the IEEE OLSR standard. One of the more popular installs is
http://freifunk.net/ from Germany.  

 

Also <a href="http://www.locustworld.com/">Locustworld</a> has a pretty good
product that is used commercially quite widely.

 

That being said, I still like the meshcom solution as it layers two fairly
stable technologies for what looks like a nice robust solution.

 

>From a business perspective, and that is what this list is about, getting
into mesh is another world from ip-telephony.  Mesh is probably as
complicated as sip and iax.  I find the concept of a manet running sip to be
quite exciting.  But there are still many technical issues that I have not
been able to resolve.

 

1.	How do you manage QOS on uncertain bandwidth? 

2.	How do you manage DIDs on temporary nodes? 

3.	How do you manage your sip.conf for extensions that may float in and
out?
