Data radios and clients
by Bryan Fields 26 May '16

I've been doing some work looking at the HamWAN standards <https://www.hamwan.org/t/Site+Bill+of+Materials> for access/client data radios. Basically this will setup us for a 2x2 MIMO AP and client capable of hitting 65Mbit/s over the air in a 10 MHz channel at 5.9 GHz. We can still use the older client radios with this which do not support MIMO, but at 37.5 Mbit/s over the air data rate. Here is a brief explanation of MCS index values. <http://www.digitalairwireless.com/wireless-blog/recent/demystifying-modulat…> Below is a list of the 3 AP's and antennas and 3 client radios. I've added in the WaveGuard shields which increase the performance of the sector antennas by shielding the back side radiation from them. The cable is already installed from the shelter to the top roof on the building, so installation and configuration of this should be a few hours worth of work. The cool thing here is the client setup is under $200 and about the same price as a entry level HT.

We'll blanket most of Tampa Bay with very usable -75dBm signal. Any ham needing a link will be able to get on here and light up their repeater/base site with an IP connection. -- Bryan Fields, W9CR Florida Simulcast Group, Inc.

Site Update
by Bryan Fields 15 May '16

15 May '16

I went over to the site today and made some progress on things. A Ex4200 24pt/8POE/2x10g layer 3 switch was installed and cabled up to the patch panel. A serial terminal server was installed. Flashing and roof patch was used to fill in the open hole above the non-functional AC unit. The inside of the shelter where the holes for the AC unit are have been closed up with insulation and HVAC caulk. The window AC unit we installed up there was attempted to be repaired, but the replacement control board did not work. This is a minor issue as the buttons on the control board that is there does not work, but we now have an IR remote and it works to control all functions. The 927.050 repeater was changed to be in "Hearclear" mode for analog access. This is basically companding with some IF processing. We're ready to get some data radios going and internet linking of the repeaters once the far end of the fiber comes up. I'm speaking at the TAPR forum at Dayton Friday, so I'll not be able to get this going next weekend, but I think it will be worth the wait. 73's -- Bryan Fields, W9CR Florida Simulcast Group, Inc.

Fiber is in.

Wanted to update the group, we have the fiber run from the roof to the 7th floor terminated now. Jerry, KD4YAL has a /23 allocated and LOA'd to us We need to get a router that supports fiber SFP's to light this up, and I've ordered some patch cables from the SC to LC interface on the SFP. I'm thinking of the following for a route/switch: Juniper EX3200 or 4200 with the SFP ports. These support PoE. Cisco 2851 with 24pt switch card. It's basically a switch with a router, and not as good as the juniper in terms of performance, but slightly cheaper on eBay. I have a 7210 SAS but it's not PoE and a bit slower for routing. Also, is there anyone who has the skills or interest in running the website? It's wordpress based now, but i don't think we're married to it. I doubt we'll be able to do anything this weekend, and then next is Dayton, so it may be a few weeks to get this all working. 73's -- Bryan Fields, W9CR Florida Simulcast Group, Inc.
