[HamWAN PSDR] Haystack coming up as a 2nd gen site

[Dan Ransom, PE]

Bart,

I want to help tomorrow. I can arrive around 10:00 a.m.  (It's 2--2.5 hours from Port Orchard.)

>>> 
>>> 1) The sector modems are dual-channel (MIMO, RB911) instead of single-channel (SISO, Metal).  This, in theory, doubles speed while still using the same bandwidth.
>>> 2) The sector antennas are dual-polarity, and higher gain to (mostly) compensate for the power loss of going to the lower-powered MIMO modems
>>> 3) The sector antennas and dishes feature shielding materials to minimize interference between the radios
>>> 4) All the modems are in metal enclosures to prevent any stray radiation and interference

>>> This 2nd gen architecture is fully compatible with 1st and 2nd gen clients.  Going to a 2nd gen client may not actually be the speediest thing for you!  The 1st gen client setup (Metal 5SHPn + Poynting 30dBi grid) offers better gain + EIRP than a typical RB912 + 2ft dish 2nd gen client setup.  That added signal power may actually prove to achieve faster speeds than the added 2nd channel of dual-polarized MIMO signals when your signal levels are low.  If your signal levels to the site are high, then switching to a 2nd gen client should be beneficial.

>>> I have footed the $601 bill (shipping included) for the upgrade. I have also allocated one of my personal MIMO sector antennas (~$150 value) to the cause.  If someone feels like raising a vote to compensate me fully or partially, that'd be awesome.
>>> 
>>> The reason for the rapid action is I got word our site sponsor would like to deploy this weekend.  I'm not sure if the hardware will make it in time at this point, but at least I tried.  If it doesn't make it, we'll do a 2nd round of deployment later. There's plenty of work to be done at the site with installing the mounting points and solar power system.
>>> 
>>> BTW, if you'd like to volunteer your time and energy, the deployment is sometime this weekend.  The mountain is near Sultan, WA.  I don't know which day(s) we're going up.  Let me know if you'd like to help.
