I am in agreement. Mesh is being abused by some people. Mesh is a
routing mechanism in the same way that RIP and OSPF are routing

RIP or OSPF to organize and automate your routing. That is all we are
doing with OLSR, just addin
It uses a 5.7-8 GHz radio for backhaul and 2.4 GHz for access.
Thats the first mistake of the gear. It should take advantage of 5.3Ghz and
5.4Ghz, for creating its backhauls. Using 5.8Ghz for short range backhauls,
just means that they plan to go head to head against Super Cell providers.

As I recall the 60 GHz band has the problem of major attenuation because the

What I might not have made clear in previous posts, MESH is to broad a term

Jack,
When a dropping the pigtail off the desk breaks the connection to the
N-Femail connector, that is just not acceptable.
SWR should be low if loss is low, but, I have a pigtail here that is

lower frequencies, that is a

So how much spectum is needed? 24ghz is fairly clean, 60 ~ 70 is very
clean. The problem is NOT the lack of spectrum. It
is the lack of gear for the spectrum that would do well for mesh. Low

The short range will help with self interferance
After discovering a >5db variance in the pigtails I have when tested at

I need mmcx to N-Female and u.fl to N-Female. 6-12 inch lengths will be

Any recommendations?

I agree with you that RF engineering and RF limitations are not being
fully
considered in most mesh deployments. Most mesh designs I have seen are

No im not falling for that trap. Your example used a 100% node to node
connection rate, that is not reasonable for wireless.
2 to 5 radios/node is. This reduces the network update messages. My idea
with a 3 radios is 1 BH AP, 1 BH CPE, 1 Client
