Re: [WISPA] SOLVED - Signal Strengths
We've actually seen quite a bit of multipath this year. Probably 3 or 4 sites had to have the antennas moved. Several others aren't working as well as they used to, but we've got no where to move the antennas to. It's a hard problem to diagnose. We had one customer that's been with us for a couple of years now. He always had somewhat slow, but usable, speeds. Finally things really got bad. I noticed his signal levels was WAY below what it should have been. Ahh, I've seen the Tranzeo cpq radios go deaf before so I put in a new radio. It was better but not right. Hmm. I then unmounted the radio and tried moving it around a bit. (He shoots over the road and under some BIG high voltage lines.) We ended up moving his antenna down 2 or 3 feet and over by about 6'. His signal levels went WAY up and his speeds more than doubled. The best part of all? He's not called me since that day! In the real world we can't always avoid multipath. We can only minimize it. When things just don't seem right on a link, it's one of the things I check for. Oh yeah, out here, in the rolling hills it hits us worse in the spring. Somewhat in the fall, but mostly in the spring. I *think* it's got to do with how the weeds etc. deflect the signals. Either that or just the water levels in our normally bone dry dirt.

Re: [WISPA] Interesting BGP Redundancy Opton for FREE
Butch, You completely missed my point, ot the background to the thread.. Of course you can build a tunnel of just about any MTU size on your network. The issue at hand is what max MTU size OTHER upstream ISPs allow on their network. Scott was talkng about doing a tunnel accross an end user Comcast circuit. With the open Internet, the two end point end users don't really have control of what ISPs in between gets traversed from End Point A to B. The ISPs in the middle could chance at any time. This is not a new problem For example A number of years back Universities built a private experimental transport network to support high MTU above 9600, so that their GB and 10GB networks could pass full capacity. As you know, max transfer rate is directly proportional to latency times packet size. Most common ISPs only passed 1500MTU, therefore the Universities had to make their own net. This has been a challenge for years for even passing VLAN tags or MPLS data, where layer2 fiber carriers would only pass a 1512 packet. When you are the end user, the answer is to shrink your MTU, so after the tunnel overhead it fits into the ISP's max 1512 MTU. But when one is an tranport ISP that transports many customer's data, it is not appropriate for the ISP to shrink his MTU below 1500, as all the other end users would not know that the MTU was shrunk, and would not have their routers set to a smaller MTU to fit. Sure you can allow fragmentation, and TCP will automatically split the packets to fit, but it has been common ISP management practice to disallow fragmentation for various reasons that I don't want to get into in this thread. And yes, there is MTU autolearning, but again, not supported by everyone or all protocols. So sure, the ISP can make a tunnel setting a lower MTU, so after tunel overhead, it will fit in the uipstream's 1512 MTU. But then full size packets (because packets comming from end user customers will be 1512 size) inside the tunnel will get fragmented to fit into the tunnel. For long haul backhauls, there can be side effects of just simply allowing fragmentation on the routers without any further consideration. Again, we have a good solution for this... It is called CIPE. Its a tunneling protocol that splits the packets appropriately for optimal efficiency. I understand how CIPE works because it is what we use. I can't say I understand the methods that Mikrotik may use. So, what I asked is how Mikrotik can deal with that problem, because Mikrotik does not support CIPE.

Re: [WISPA] Interesting BGP Redundancy Opton for FREE
Hello again... I didn't specify comcast but in the context of our discussion it doesn't matter much :) Tom... Lets just do a test from your network to mine. A learning experience if nothing else - can't go wrong there. I've never heard of CIPE but I assure you that MT has no problem whatsoever passing traffic from anyone over a tunnel between us, I think you are hung up on something that is a non-issue and what Butch mentioned was not about over one's own network - he understood that it was from some end user provider to another with multiple possible ISPs in the middle... its a mute point who's in the middle really with whats being proposed and how it works. I have a router ready to go, you? Latency between us is good, less than 30ms. I 60MB on any given day/time still available not doing anything, usually a little more.

[WISPA] Wifi on AM Radio Tower?
Hello There, I am a volunteer IT guy spending some time in Honduras. I sent the list an email awhile ago for some knowledgeable guys in the WISPA space and I was impressed with some of your members' willingness to help. Im sending you guys a message so i have some feedback. We are here in Juticalpa, Olancho, Honduras. We have a tower that we are housing some multi point equipment on. A low grade omni, with no back haul where other sites use to get connectivity as our Demarc for internet doesnt have LOS to all of our sites. Our sites are schools, 3 of them: Special needs, Elementary, High School. The current problem is the network is slow end to end (from Site - multipoint - demarc(internet) we have 800kbps, and 300ms) over 2.8kilometers. We are putting a plan together to build a backhaul (new radios) and possibly better antenna coverage if it is possible 1) Our multipoint site has two towers available, we are using one of them. 2) The second tower has an AM Radio attached to it. 3) The AM Radio is broadcasting on 650Khz @ 1KW of power on the 100meter tower 4) We have a smaller tower (20Meters) with some 200mW 2.4Ghz Wifi Radio 5) This WIFI radio is acting as a bridge to other sites we cant get LOS. The idea. 1) Rebuild the multi point with a 2.4Ghz back haul PTP, and a new Omni directional radio @ 300mW 2) Move the setup into the 100Meter tower on the same tower with the AM transmitter for better LOS coverage. The expectation of a problem: Will that work? Are we crazy to put a 2.4Ghz antenna @ 300mW on the same tower as an AM Transmitter on 650Khz @ 1KW. I am honestly expecting RF overload on some of the radios to cause problems. If thats not the case, then we could use the higher tower to serve an area better. We are not running a WISP here, mainly providing data connectivity between schools.

Re: [WISPA] Interesting BGP Redundancy Opton for FREE
Scott, Actually, I originally missed the part about mikrotik router. We don't use Mikrotik routers currently, as they can not accommodate us loading our custom management software code. But all our servers are Linux based, so can likely do anything that Mikrotik can, (with a little bit of effort). Butch was suggesting using PPTP. I need to double check that we have a PPTP package loaded on our routers, and if not, load one first. (I could always get a MT box to do the tunnel, and just allocate an Ethernet port on my Linux router to it, but I'd need to procure a MT unit first. ) I agree, at minimum, it would be a fun experiment,with no disadvantage. We have plenty of free bandwidth. We should probably take this offlist, at this point. We can always share the results with the list, after the fact.

I didn't specify comcast but in the context of our discussion it doesn't matter much :) Tom... Lets just do a test from your network to mine. A learning experience if nothing else - can't go wrong there. I've never heard of CIPE but I assure you that MT has no problem whatsoever passing traffic from anyone over a tunnel between us, I think you are hung up on something that is a non-issue and what Butch mentioned was not about over one's own network - he understood that it was from some end user provider to another with multiple possible ISPs in the middle... its a mute point who's in the middle really with whats being proposed and how it works. I have a router ready to go, you? Latency between us is good, less than 30ms. I 60MB on any given day/time still available not doing anything, usually a little more.

Of course you can build a tunnel of just about any MTU size on your network. The issue at hand is what max MTU size OTHER upstream ISPs allow on their network. Scott was talkng about doing a tunnel accross an end user Comcast circuit. With the open Internet, the two end point end users don't really have control of what ISPs in between gets traversed from End Point A to B. The ISPs in the middle could chance at any time. This is not a new problem For example A number of years back Universities built a private experimental transport network to support high MTU above 9600, so that their GB and 10GB networks could pass full capacity. As you know, max transfer rate is directly proportional to latency times packet size. Most common ISPs only passed 1500MTU, therefore the Universities had to make their own net. This has been a challenge for years for even passing VLAN tags or MPLS data, where layer2 fiber carriers would only pass a 1512 packet. When you are the end user, the answer is to shrink your MTU, so after the tunnel overhead it fits into the ISP's max 1512 MTU. But when one is an tranport ISP that transports many customer's data, it is not appropriate for the ISP to shrink his MTU below 1500, as all the other end users would not know that the MTU was shrunk, and would not have their routers set to a smaller MTU to fit. Sure you can allow fragmentation, and TCP will automatically split the packets to fit, but it has been common ISP management practice to disallow fragmentation for various reasons that I don't want to get into in this thread. And yes, there is MTU autolearning, but again, not supported by everyone or all protocols. So sure, the ISP can make a tunnel setting a lower MTU, so after tunel overhead, it will fit in the uipstream's 1512 MTU. But then full size packets (because packets comming from end user customers will be 1512 size) inside the tunnel will get fragmented to fit into the tunnel. For long haul backhauls, there can be side effects of just simply allowing fragmentation on the routers without any further consideration. Again, we have a good solution for this... It is called CIPE. Its a tunneling protocol that splits the packets appropriately for optimal efficiency. I understand how CIPE works because it is what we use. I can't say I understand the methods that Mikrotik may use. So, what I asked is how Mikrotik can deal with that problem, because Mikrotik does not support CIPE.

Re: [WISPA] Wifi on AM Radio Tower?
Most of the time, an AM tower is HOT. IE, the entire tower is the antenna. This presents all sorts of issues with coupling the equipment at the base of the tower, etc. Most people will not work with a hot tower.

Re: [WISPA] Wifi on AM Radio Tower?
Here's some ideas: 1. if your user base is on 2.4 ghz then use 5.8ghz for the backhaul, especially if you want to build your system with some room to grow in the future. Using the same band for your backhaul and for your user base severely limits your throughput and pretty much ensures you have no room to grow. There's a lot of cheap 5.8 ghz gear out there that works great for backhaul. 2. shielded Cat 5/6 cable anyplace you're using cat 5/6 cable between equipment that's in a high rf environment to eliminate or reduce interference 3. ferrite beads on the coax and power cables to reduce or eliminate interference. 4. eliminate cable and use rf where ever possible for long links. Using long runs of cat 5/6 cable will introduce points of entry for rf interference and also failure points for the inevitable nearby lightning strikes.
