[WISPA] advice on Redback solutions?
For a campus wireless network (~30K people), I'm researching the possibly of creating a seamless roaming solution using using Redback to be the endpoint for approximately 500-1000 L2TP tunnels using BCP (bridge control protocol) encapsulation http://www.ietf.org/rfc/rfc2661.txt (L2TPv2, not L2TPv3) Cisco 7200s work, I'm told. And then I could bridge together some of the these aggregate points via MPLS so that all of this wireless traffic does not hairpin back to the datacenter and congest the line. But others have told me that the Redback solutions would be a much better solution if for networks with millions of subscribers. Does anyone have any advice on Redback here? Or does anyone have any other suggestions on solutions that would scale better? WISPA Wants You!

[WISPA] ptp400 5.8ghz bandwidth adjustment
I have a ptp400, that is a full link and am able to get 19.80mb/s each way. Is there a way to adjust throuput from the master to the slave, like there is in an ap/sm setup? My goal would be to get it 25-30 down to the slave and 15-10 from slave to master. Thanks for any help on this. Alan Long Aerowire, LLC 687 North Dean Rd.

Re: [WISPA] Mac Dearman OT
My Dr. says my problem is hereditary (Macs is not). He said that diet doesn't hurt as much as the genes mom passes on. If this is the problem, unless your diet is less than 10% fat (almost impossible unless you just eat grass) you will continue to make too much cholesterol. The only way to control it is the meds. I watch what I eat as much as possible and limit beef or pork to once/week and no 22oz steaks:-( If I thought I was going to live this long, I would have taken better care of myself ;-) Jim Jeff Broadwick wrote: Since I got mine under control, I've gone back to some of the stuff God made like butter and eggs.

No cheese, bacon, sausage, cookies, doughnuts, beef, butter. Look for healthy alternatives. Believe it or not, before long even the heart-healthy foods will taste good. Seafood, no-fat cheese, more salads and very lean ham or turkey are good. No beef. Just read the nutritional labels on anything you buy before it goes in your mouth. I don't eat anything with more than 2 grams of saturated fat per serving. Meds: The docs played with the meds for a while until we finally got the LDL down 70. I'm on 10 Mg Zetia, 80 Mg Pravastatin (generic equivalent for Pravachol), 10 Mg Lisinopril (blood drug) and a baby aspirin. The statin drugs are notorious for causing muscle pains, but I don't have any problem tolerating the Pravachol. Word of warning to all: If over 40 I suggest that you have a test done to determine if there is any plaque buildup in your arteries. Don't rely on a simple stress test in combination with an annual physical to determine if heart-healthy. I had a stress test in which nothing showed up, 6 months before the heart incident (80-90% blockage in main arteries). Since my experience, all of my friends over 40 have had a heart CT scan (or some equivalent) done. One of them owned his own telecom company, and after the test, went out and bought a $10 mil life policy because they found something.

While nothing is more reliable then a person actually being there, you could look at something IP related. I know there are thermometers used in NOCs to warn techs the temperature is too high, I would expect the opposite being pretty simple.

[WISPA] Ceragon, Dragonwave and whatelse?
Dear All, we are considering to move to licensed frequencies for back hauling and therefore some hints would be really appreciated. We are looking at 2 main manufacturers (Ceragon/Dragonwave) so the problem is which one fits better for our needs? Just to summarize: a) links are around 20-25 miles b) antennas: the smaller the better c) robustness is very important d) average life: 3 years From what I have read in the data sheets I have done the following considerations: 1) Dragonwave Horizon is nice but only if your site is well protected from sabotage and stealing. The all outdoor approach is nice but it has the drawback that if somebody takes the whole unit they will have a brand new unit working. With the IDU/ODU approach they will have only half of the banknote, so after the first or second time, they will not spend time having something useless. 2) Dragonwave Horizon can be a problem if you don't use fiber from the unit down to your switch. In few words, we have sites with huge amount or EM fields, so even using shielded cables (e.g. Belden 1300A) we get only few ethernet megabits. So we should use fiber to go up the tower, but maybe be IDU/ODU approach is more robust (comments welcome). 3) All outdoor means that when you have to re-use the devices somewhere else, you have to buy a whole new thing instead of just swapping the ODU. 4) In any case the (all outdoor or IDU/ODU) when the tower is frozen (and when I mean frozen I mean a whole block of ice) then it does not change much, you have to wait the better season to work on that. 5) Performances look more or less the same. 6) I don't know much about prices, I have looked on some website, I am still exploring this aspect 7) Is anybody using the software-switch capabilities on this devices or just using them as transparent bridges for your router/switch?

Re: [WISPA] Ceragon, DragonWave and whatelse?
DragonWave has their Horizon Duo, which is a split mount system. If you enable the second radio in the unit you take a pretty TX power hit though. No 6ghz radio though, which you will want at 20-25 miles. I had a ton of problems with my 2 Airpair 11Ghz links. Knock on wood, they have been running for about a year now though. Ceragon makes a very good radio, but lead times for 6 and 11ghz high power stink. I put an order in at the end of October and have really been hounding them. I should have the rest of my order next week. I bought 5 links, 4 11ghz and 1 6ghz, all high power. If you don't want/need high power it should be better. I bought IPMAX2 HP because I can move the RFU's indoors if I want and gain another 3db of TX power. I also would look at Nera. They have a radio that is pretty nice. No 256qam or hitless adaptive modulation yet, but price and delivery seem to be reasonable. Nera also seems to have the best system gain in the market, 102db. DragonWave will probably be cheapest, but they don't have a split mount 6ghz radio. No experience with Nera yet, but I plan to this year. I really think Ceragon has the complete package at this time, but getting equipment is like pulling teeth. My 2 cents anyway.

Re: [WISPA] Ceragon, Dragonwave and whatelse?
Take a look at the Trango GigaLink and APEX radios. They make both an IDU/ODU and just an ODU option. We just installed the APEX 18ghz systems. At one location we used the fiber option and it works great. You can contact them directly (www.trangobroadband.com) or contact Charles @ CTI. They are selling the 18ghz version with 2ft dishes for $9,995 right now (complete link).
