[WISPA] Powering 12-volt CPE via battery for site surveys
What is the best way to power a 12-volt radio for 30 - 60 minutes before requiring a re-charge? (solution must be re-chargeable via auto adapter) We are wanting to use an actual CPE radio with a 19dBi panel antenna, connected to an iPAQ/Axim so we are needing a re-chargeable power source for the radio. BTW, we tried a 9-volt battery but it only kept the radio powered up for 5 - 10 minutes. Would something like http://tinyurl.com/vgm4n work? Shannon D. Denniston, Co-Founder KyWiFi, LLC - Mt.

RE: [WISPA] Powering 12-volt CPE via battery for site surveys
We use the 18V DeWalt Flashlights and take the head off. Put a Cat5 plug on it where the flashlight head was, and you can inject power into the devices. Be sure to use a volt meter because on the one I had, Red was negative, and Black was positive. If you make a Cisco Reverse PoE cable, you can power the Motorola gear too. We used the DeWalt gear because we use the drills, and they all take the same battery.

RE: [WISPA] Powering 12-volt CPE via battery for site surveys
1 hr??? We use them for a site-survey and are done... I know they last more than 20 minutes. Don't know what kind of devices you are using, but Tranzeos, CB3s, and Mikrotik (all what we use for clients) support 12-22VDC. Then the Motorola is supposed to be 24V, but 18V still powers it.

RE: [WISPA] Powering 12-volt CPE via battery for site surveys
We use 18volt Bosch batteries from our cordless drills to temporarily power cpe's for sight surveys. Not sure how long they would last under continuous use. We use them because they are part of our tool supply and are always charged.

[snip] You think his radio might be failing? I ahve no othe symptoms on channel 11 or 4 to any other clients (other than 11 is 3 db stronger to a couple of clients who are quite distant and I think are in a noisy area). And yes, this is ALL on 11b mode. It sounds to me as if this client was simply being forced to talk at the 1M rate, which brings down your entire cell because he's taking up so much channel bandwidth everytime he has to send. This is one of the major great failings of 802.11b/g/a/etc, that clients have this type of effect. Probbly, your single client here is able to 'hear' something that your ap doesn't, and that something is on 11 or at least within that span of frequencies. This is a game I espically hate - changing channels for the benefit of a single subscriber, to the potential detriment of others.

I only saw it for a brief instant though. This interference just does not last long enough to be caught. The high latency is caused by retransmits but I am sure outside interference is what is leading to the need for frames to be sent again. This effects all channels across the 2.4 GHz bands. We have seen the noise floor jump up higher than our radio power levels when this problem happens. What ever is causing this is running higher power than anything we have in the field. We will look at anything, though, to help troubleshoot and I appreciate your ideas. Scriv We've had this too and have never been able to narrow it down. Basiclly, certain areas and without warning or obvious cause, simply become dead for 2.4ghz in that there appears some very powerful inband interference that is not 802.11b/g and has no obvivious source we can find, but the area of effect is fairly localized (using affected customers to tirangulate). We also have a problem within our hometown of repeatedly experiencing burnt out 2.4ghz equipment. Never happens anywhere else in our county wide footprint, just our hometown and across a wide variety of equipment such as smartbridges, atheros, prism 2.5 cards, cb3's, cisco aironet, you name it. Been looking at this problem for years and simply don't understand it. We've had events like this occuring down one particular street for example and an accesspoint not too far away, all in the space of one evening. We've also had events like one subscriber per day (on 2.4ghz) winding up with burnt out prism card, requiring a truck roll and card replacement.

I use a 100 watt inverter that plugs right into the cigarette lighter power port. May not power the laptop (haven't tested) but the CPE will stay on for much longer for an hour.
