[WISPA] Lightning Protection
Spring arrived in Kansas City and so did the thunder storms. I took a lightning stike on my tower and lost both APs, the POEs, two switches and a Mikrotik router. The Antennas survived but it looks like I lost a little gain. My question is how do I protect against this happening again? Are lightning rods effective? Any thoughts will be appreciated. I don't want to have to replace everything again.

Re: [WISPA] Network Monitoring and Graphing
I run PRTG Traffic Grapher from Paessler (www.paessler.com) and Servers Alive (www.woodstone.nu/salive/) for notification. They both do notification but I started with Servers Alive because it's freeware and it works.

[WISPA] Spring has sprung!
..and the leaves have started to absorb my 2.4 GHz signal! Good morning everyone! With the sap rising in the trees, I've started losing a lot of signal with some of my customers on the other side of the tree line. I thought this might happen but was hopeful it wouldn't. Wi this said, I am committed to adding 900 MHz gear to my portfolio,. but have some questions for the group. I'll be using the same tower for both 2.4 GHz and 900 MHz. I'm assuming antennae separation is important but how much and should they be spaced vertically or is horizontal spacing OK? I'm planning to use an RB112 with an SR9 for the NLOS clients and adding a second RB112 with an Xtreme Range 2 for my 2.4 customers. I would like to run these in bridge mode instead of having them do any routing. Any thoughts or gotchas here? I'm assuming that my EIRP for both implementations is 36 dbw. Is this the case? I'm running my 2.4 gear in HPOL but am considering running the 900 gear in VPOL. Any thoughts here? And lastly, I have read that a cavity filter is strongly recommended for the 900 MHz gear. Any thoughts and/or suggestions here. As always, thanks in advance for the help.

[WISPA] Mixing 2.4GHz and 900MHz Gear
Folks, I am getting interest from potential-customers that do not have direct LOS to my antennae.

Re: [WISPA] Wireless Backhaul - Where Do I Begin?
Thanks to all who replied to my initial question. It might help to understand what I'm doing now and want to do in the future. My wife and I live in rural Cass County Missouri. We're too far out for Cable or DSL and Satellite is out of the question due to the havoc that huge amounts of latency wreaks upon VPN clients So in order to get a high-speed connection out in the country, we dragged a T1 line to the house, stood up a 30' tower and began selling bandwidth to our neighbors. I learned all I know about this stuff at last Fall's ISPCON in Santa Clara so I'm feeling a little bit wind-burned right now. This is also where I met John Scrivner who convinced me that joining WISPA was a great way to gain access to this community and continue to have the support group that I need. Well, a few months have flown by and once word leaks out that there is an affordable high-speed Internet connection available, they truly beat down your door wanting to know when they can be installed. I'm having a great time, enjoy the people and am considering making this more than just a Hobby WISP. We are about 30 or so miles from downtown Kansas City as the radio waves fly, and are relatively high up. I spoke to my provider (ATT) about additional bandwidth and out here they can continue to bring me T1 lines across copper, but I have to believe there's a more cost-effective solution available. This is why I posed the original question. I feel that I could serve about 500 clients in this rural area and would like the option of scaling up to 45Mbps to support them. Obviously bandwidth distrubution comes into play along with detailed planning and design, but at this point, I'm just looking for ideas to help me formulate my plans. As always, thanks to all who have responded and continue to assist met!

We look at three primary things when addressing backhaul needs... They are in order: 1. Path Analysis and Distance, Without LOS between the two desired sites usually you can kiss the link goodbye. If there is LOS then how far we are shooting helps determine antenna sizes. 2. Frequency Usage on site - Again helps determine the radio type. 3. Capacity - Helps determine radio type. So. Figure out where you are shooting from and to. If that is OK then find out what frequencies are in use at those sites. Then know how much Bandwidth you will need or want. To address your specific questions. I would check with your current provider and ask them upgrade questions. They may be able to provide you with a fractional DS3 at really attractive rates. If they can't provide that then ask them if they recommend a carrier in your area. I would then need to look further at your network to determine best backhaul to the different legs of the network. Transport of choose is 5.8Ghz radios and then probably licensed. Distances are form 0-40+ miles. The farther you shoot the better the planning and budgeting needs to be. Typical links seem to be between 5-20 miles... Bandwidth - Licensed can be out of this world fast but you are probably looking at unlicensed, 18-54Mbs over the air which translates to about 10-35 actual throughputs max. We would base that need on planned growth over a one to two year period. Cost = Cheap - very expensive. All based on need. How much do you want to spend???
