I agree. It costs $100 for each smartphone people have yet they want to download 50-600gb for $30.

[WISPA] Possible interference with Alvarion 2.4 / 5.8 GHz
Hi, I have 2.4 GHz and 5.8 GHz AP´s in a tower where a company is planning to install above our antennas a channel 24 LPTV antenna receiving on 647 MHZ (channel 43) and transmitting on 533 MHz (channel 24). My question is if the harmonics could cause any interference to us or could be an issue? These are the specifications we received from the company: The transmit power will be 580 watts on TV channel 24 which is 530-536 MHzThe transmitter is heavily filtered with a stringent mask to eliminate out of band energy. http://louise.hallikainen.org/FCC/FccRules/2010/74/794/If there are any problems it's likely due to front end overload of your equipment. That can be easily resolved with the addition of filters between your antenna(s) and receiver(s).If your 2.4 GHz equipment suffers any interference I'd propose an L-com BPF2400A: http://www.l-com.com/item.aspx?id=22046If your 5.8 GHz equipment is bothered the BPF5800A should eliminate any issues: http://www.l-com.com/item.aspx?id=22184Any comment will be welcome.

Re: [WISPA] Possible interference with Alvarion 2.4 / 5.8 GHz
The first thing I'd clarify is who has interference protection priority, in their colocation agreement? You or them? This will define who has to assume the burden of cost or unconvenience to resolve and prevent interference. Are your AP Antennas integrated or embedded? If embedded, the other party does not under stand the FCC certified system rules, that prevent you from inserting filters, which you couldn't do either without changing your APs to ext models. I would argue that front in overload is a likely possibilty. I'd argue that you should push to have the other parties new equipment to be installed at a location a safe distance vertically away from your antennas, to prevent the overload, and to pre-calculate what that safe distance needs to be. (also de-sensitization could occur) Or, if this is going to be a trial and error thing, that its made clear the proceedure and timeline for resolution (which should be immediate) if interference is heard. I'd suggest being available on day going live, so you can have them shut down, if link quality get hurt for your customers. If you already have ext model ap in the air, it may be easier to just buy and install the filters as a precaution, if the insertion loss is acceptable to incur.

Re: [WISPA] Possible interference with Alvarion 2.4 / 5.8 GHz
They are pretty far out of band for the two bands you mentioned. I would bet that no interference will be noticed. They would have to have some pretty bad radios to get you with harmonics on the RF side. You may experience some Ethernet issues depending on separation and your shielding, but I would also bet it would be a non issue. FM transmitters near 100MHz are like a bullet to the head for Ethernet.

[WISPA] Any Mikrotik experts hanging out tonight?
Hi, Any MT gurus hanging out tonight. We have a powerouter 732 that we upgraded from v3.22 to 4.17 tonight. When we upgraded it complained about a new license and we did the automatic upgrade and it rebooted just fine. The problem is that I cannot reach it now via the public ip addresses. Was working great before the upgrade. I can access it just fine over the two routed internal interfaces but not the masq interfaces. We have three different sources of bandwidth on 3 of the ethernet interfaces and two of the ethernet interfaces have our rfc1918 addresses with clients on them. There are masq statements for each of the 3 bandwidth interfaces for 192.168.0.0/16 to only go out that particular interface. We then use policy routing to send the traffic out the different interfaces. It was working fine until the upgrade. Now torch shows that there is no traffic going over the interfaces. If you go to the nat statements and look at the masq statements, the counters are increasing like they are being hit but the traffic is not leaving the interface. Any idea what may be happening or more importantly what information is needed to properly get this working again and fixed? Worked very well before and to my eyes, everything looks good.
