If there is a powered light poll nearby it might still be a site you could consider for your AP. You’ve said that ownership would sometimes be an issue but they would give a high vantage point that could be beneficial to the bridge link but would also serve a wider area. I would also be concerned with the damage of the PV panels. You’ve probably also thought of it but the likelihood of someone climbing onto the roof of the bus stop (for a selfie, because; selfies, or whatever) and damaging the panels at some point is almost inevitable. That’s before you consider tree limbs falling, crews working in the area without regard, etc.. My concern would be that it would put too much hardware in reach of too many people.
I think there’s certainly cases for it and you might be on to one of them. I know we will all be interested to know how it turns out. -Paul Reimer From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of James Helzerman Sent: Tuesday, July 25, 2017 8:01 PM To: [email protected] Subject: Re: [WIRELESS-LAN] Solar Power AP Setup Thanks. Most of our bus stops dont have power or lighting. The light is provided by nearby street lights that don't have constant power. Some are owned by the university others are owned by the city. I have been looking into the terrawave solution and have a call in with their solar person and electrical engineer to go over the requirements and if it will work for us.

If so, have you considered using it as the power source? Even if you don’t own then, renting power from this is probably less money than the solar install and the long-term maint. For solar, my guess is you want solar charging with a battery to supply the WAP. Ventev (terra-wave) makes a POE+ system for WAPs but they are $3800 a pop.

For this proof of concept 2.4Ghz is good for users but I would be looking to us 5GHz for both in the future with a Cisco AP that do FRA. -Jimmy On Tue, Jul 25, 2017 at 3:58 PM, Paul Reimer <[email protected]<mailto:[email protected]>> wrote: We aren’t running anything on solar. I have a question though. What’s your backhaul? Are you thinking of bridging to the bus stops? -Paul From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]<mailto:[email protected]>] On Behalf Of James Helzerman Sent: Tuesday, July 25, 2017 3:33 PM To: [email protected]<mailto:[email protected]> Subject: [WIRELESS-LAN] Solar Power AP Setup Has anyone used or currently have any access points powered by solar panels? I am looking at doing a few proof of concepts at some bus stops to try and provide connectivity for those waiting for the bus. I am interested with the following particular questions but please add any comments or suggestions you may have. Questions: What make/model solar system do you have? What APs and antennas are you using? What are the power ratings of the solar system (12v, 48v, 120v, wattage, etc.)? How does the AP connect to the power such as a power injector running 120v, direct connect via DC, DC-to-DC converter, etc? What is your targeted uptime? Ie how long should the battery last in the event of bad weather. Any other comments or stories to share would be most helpful.
