HSMM-MESH Valley Hub Sites Testing!

Email regarding HSMM-MESH from David Bauman, KF7MCF, sent on October 30, 2013


Two Sites in Test Mode!

SLCC (Salt Lake Community College Hub Site)


The above photos show the SLCC Valley Hub Site.  It is composed of a High Power 2.4 Ghz Ubiquiti Bullet attached to a 15 dbi Commercial Omni Antenna (spec sheets attached).  The funny looking thing I am pointing at is a plastic pop bottle that is temporarily protecting the POE unit from the elements.  (Grant has replaced that with a weather proof box.)

This site is on top of a four story building at the Salt Lake Community College Campus.  It is running as an access point with regular Wi-Fi on Channel One with over 20 watts ERP output. With a little luck, the right equipment (and clear Radio Line of Sight) you should see it within about 5 miles, and you may see it out as far as 10 miles with the right equipment, skills, and circumstances.



Below is a view shed or rough idea of where the signal will hit out to about 5 miles.  The bite out of the circle at the bottom is because of elevation difference - Might be a coverage area also with a good antenna and a good Ham.







Ensign Peak Hub Site Testing also!







It is composed of a Linksys WRT54 router running HSMM-MESH 4.3 into a Renasis 1 watt Bi-directional Amplifier, and then Into a 17 dbi gain 90 degree Sector antenna with a bit of a down tilt (about 4-5  degrees)  


Below is a plot showing the Possible coverage area out to 10 miles.  If you are about half that distance, you have a good chance of connecting, with The right hardware, Clear Radio Line of Sight, and a bit of skill.  Remember, the signal does not hit the ground for about The first mile because of the elevation of Ensign Peak, and the 7.5 degree vertical beam out of the antenna.  This HSMM-MESH site is on Ch 1.  Because of the different operating Modes, the two Hub sites will not connect at the present.   Later that Will be resolved.  The Ensign Peak and SLCC sites are about 10 miles apart.  Credit for this site goes Ed Sim (N7RTA) and some of the guys from L3 group.  Nicely done!




The view below shows the possible combined coverage of Ensign and the SLCC Valley Hub Sites.  The other possible Future Valley Hub Sites shown  with distance from The SLCC Valley Hub are:  Church Headquarters (7 miles), Welfare Square (6 miles), Magna Bishop’s Storehouse (7 miles), and The Sandy Bishop’s Storehouse (6 miles), New IHC Med Center 2 miles, Storehouse Distribution Center 7 miles.
(About 10 miles From the SLCC  Hub Site to Ensign Peak.)




The View Shed picture below shows Possible future valley coverage from all proposed Valley Hub Sites





We are making progress, it is slow, but someday…

Thanks for all your help!  Anyone that can help us get other proposed sites up, or that just want to participate, just let us know.  Meetings are held Saturdays at 9 AM at the Magna Utah Bishop’s Storehouse ERC Com Center on 2nd floor. You are welcome to come and join with us, and have a donut!
