wft-e5 in a remote area

[eduardo_barrento]

<p>I have a (maybe silly) question: If I use a WFT-E5 in a remote area, without internet acess, can I use the EOS Utility on my computer to trigger the 7D?</p>

<p>Yes, you can set up an Ad-Hoc network between your laptop and WFT, <a href="http://cpn.canon-europe.com/content/education/technical/wifi_options.do">this article</a> might help.</p>

<p>Thnk you Scott And what about the range? How distante could be the laptop and the camera/WFT-E5?</p>

<p>Depends on your laptop and what is between you and the camera, but absent other wireless traffic, you should easily get 100M... and probably much more. </p>

<p>My experience with laptop generated ad-hoc is closer to 50ft, but I have not used the 7D and WFT specifically, also the WFT does not use 802.11n, it only uses the slower a/b/g protocols. File transfer is not fast, don't expect it to keep up with a 7D and RAW files at any range.</p>

<p>The really nice thing is you can get live view so you get a remote view through the camera.</p>

<p>Very different distances :) 50ft is only 15 meters... The think for me is only to use the eos utility to fire the camera. Transfer files is not priority. Thank you both.</p>

<p>I should clarify... 100M is my best guess based on <strong>my laptop</strong> for merely <strong>triggering the camera </strong>given that you have a <strong>reasonable line of sight </strong>between your laptop and the WFT<strong>.</strong> If you need liveview or to transfer files (or cannot establish line of sight) Scott's experience is more relevant as your bit rate is going to drop tremendously as a function of distance. </p>

<p>Of course, this all depends on your laptop (not all wireless is created equal), the amount of local RF traffic in your band, the line of sight between you and the file transmitter, and general atmospheric conditions. This is something you decidedly want to test before going into the field. If you find you aren't getting the range you need, there are dozens of different solutions you can try ranging from a battery powered router to a Wifi repeater, to an external antenna for you laptop. <strong> Again, this is something you should definitely test before going out as your performance will vary quite a bit depending on your equipment and conditions.</strong></p>

<p>Just as an example of how finicky wireless can be, I recently set up a new wireless router for a friend. Exact same router that I have... and for me, I can get good signal sitting in my car two streets over. For him, we couldn't get a reliable signal through three walls (and about 15M) in his garage. Of course, we got great signal strength from a couple of older 802.11g routers from several blocks away so go figure. Wifi is a curious beast that will always surprise you.</p>

<p>If all you want to do is remote-trigger your camera, you could also use a Yongnuo radio trigger, which will trigger either a flash or a shutter, depending on how you use it.</p>

[craig_meddaugh]

<p>Yes, that is a lot easier than going through adhoc Wifi nonsense. </p>

<p>thank you for all the answers. I did a test at home with the wtf-e5 in ad-hoc mode and it works fine. Now I pretend to test it on the field, but now the weather is to bad. As soon as I do that, I will tell... :)</p>
