| Comments on WaveIP?
Other than the cost(!)...are there any issues with the WaveIP gear?
I am most interested in the 900 gear, but any information will be appreciated.
I am going to see a deployed system next week, and thought that I would give the forum an opportunity to speak up.
I will post the results of my discussion with the WISP here.

I met these guys 3 or 4 years ago at a show down here. They seem to be very enthusiastic about the business and building gear. The claims of the gear is very impressive. I would like to hear what you find. I thought for sure someone here had tried their gear out. |

I've heard that this gear can't handle interference very well at all. I helped a guy out a year ago that had it and he ended up replacing it with Airspan 900MHz which didn't have any problems with whatever interference his area had. Airspan at 900 is pretty nice if you can afford it and don't need more that 3Mb of throughput. |

Their equipment is based on 802.11b even for the 900mhz band so it probably takes a good portion of the spectrum which would be why a slower solution would work (uses less spectrum or is FHSS) |

| Not personal experience, just thoughts here:
If their technology works as advertised, they will become the front-runner in carrier grade equipment for wireless. Their specs make Canopy look like Wi-Fi.
To respond to jarosoup, what interference are we talking about? Self-interference, or just a busy spectrum? There is a huge difference there, the first being that you can engineer around a busy spectrum. Their synchro should minimize self-interference, if not, then uh oh for them.
To respond to cmaenginsb, I dont think its possible for 900MHz equipment to be based on 802.11b. Different standard, com layer protocol, and mac layer protocol. The carrier standard is the same (DSSS) but you can use DSSS to transmit/receive any RF signal. It does appear to take a huge chunk of spectrum in order to get 8MBps.
I do not own their equipment quite yet. I am going to be very interested to see how this turns out. My small 120 subscriber WISP recently recieved a lot of attention in town which is attracting mucho-moolah offers for expansion, and WaveIP is currently at the top of my list. I am not an expert on 900MHz equipment ... yet  Correct my mistakes if any.
Also, check for Gator17 or something or other. I think he just deployed WaveIP.
I look forward to hearing your report from a first hand view of their stuff.

Just because no one is talking about them...doesnt mean its a bad sign...several LARGE companies are using WaveIP and has been very successful for them. We just junked our Alvarion 900 for the Wave IP 900 and so far we love the features and reliability.
Dont knock it until you try it. |

I switched because the CPEs are a little cheaper, they also have indoor CPEs (which works better then I thought they would) and the outdoor CPEs include the PoE, something I had to either make or buy for my Alvarion units. The QoS is also very nice, the network management, while programmed in Java, runs a little slow, but it works very nicely. I also wasn't getting the bandwidth I would like to have out of the Alvarion 900.
Which of course...from what I hear the new WaveRider gear and firmware took a few pages from WaveIP's book and has very similar features. |

If you want to know....call Curt Gordy from mwinfra.com he installs it everyday.
He will not just try to sell you stuff that he doesnt have a clue about like sales reps at Tessco and other places. He knows what he is doing when it comes to WaveIP. |

jkmonroe, I suggest you visit their site and look at the radio specs. They all use an 802.11b PHY. The PHY defines things like modulation which effect the channel size. Had they incorporated a different PHY with more efficient modulation (like Aperto for example who uses 16QAM) They would have been able to get the same amount or more throughput for 6Mhz of channel width. The reason for using an 802.11b PHY was that it simplifies their R&D and reduces the cost of the product which explains why it's so inexpensive compared to it's features.
Many manufacturers do this, building a base radio that runs on an intermediate frequency and then either stepping or or down to the final frequency. This allows you to offer products in multiple bands but get the most out of economies of scale.
What WaveIP is doing is exactly the idea that Charles Wu was talking about, take a standard PHY, tweak and modify the MAC etc for your needs and put out a much better product than what can be done with that standard. However since you are using parts of a standard you don't have as much R&D time and maybe even are able to use EOS for getting compents as well.
As to 802.11b not working at 900Mhz, while it isn't a part of the standard, I can go out today and buy an downvertor that lets me take an 802.11b radio and run it in that band. Most of the technologies are frequency independant, until you have a band with special requirements (like the 5.4 band)
While I like WaveIP and certainly appreciate the bang for the buck when compared to other gear like it, it isn't state of the art when it comes to PHY which in conjunction with the marketing hype of 802.16a is why they are making an OFDM based replacement. |

I also talked with Ran, one of the sales engineers in Israel. He was walking around the streets of Tel Aviv while we were talking. He referred me to Curt, for a more stable phone connection.
Curt was the one who provided the contact here in Oregon so that I could visit a deployed system. My understanding is that there is a Government deployed system there in support of the chemical weapons burners that was recently built. It will be interesting to hear about that, too.

I have WaveIP 900 although I have been slow on my deployment not because of the gear but because of me not getting answers I needed from my dsl provider. So far the gear seems very simple. The NMS system is pretty straight forward. I have spoke to several WISP that have deployed it and they all told me that I should not have any problems with 2 to 2 1/2 indoor installs. One wisp had it on a 60 ft tower and was getting 1 1/2 mile indoor installs. Another had pretty good results as well and was also selling VOIP and has not had any troubles. Of course the distances are kind of a loaded answer because of terrain and other items. The cost are a little higher but the features are nice as stated in previous post. The radios are small approx 7x5x2 that is both the indoor and outdoor making them not such an eyesore. I am putting my antenna up on the wawter tower on Tuesday and will have more details on the gear a couple days after. One thing they do have is Curt Gordy, not just another sales guy, he is with you through the deployment, this means alot to me being a new startup WISP. on occasion I have spoken to him at 1:00 am |

A little of topic but.... That is what sells a product. Service. I know some people have a hard time getting ahold of Tony at Demarc Tech (thats who I use), but I don't. I usually get him on the phone at 8-11pm. I'll tell you one thing, I won't buy anything else from Ascendance. I called and was asking about the antenna alignment tool. I wanted to know if higher or lower numbers are better. He said higher was better and the scale was 0-100. I said "It's at 157 right now". Then he said, It must be 200 them. My point is, good tech support is the best. Even if I have to try for a day or two to get someone "good" on the phone, it's better than calling and getting the first idiot who answers, who gives out false information. |

gator, your feed back is much appreciated. Please give us an update after the setup. I have a Island with a bunch of camps on them and If I can get what they claim then the numbers would work out fine. |

"Which of course...from what I hear the new WaveRider gear and firmware took a few pages from WaveIP's book and has very similar features."
I have used Waverider gear for close to 3 years...but I'm not sure what you're referring to about Waverider's new gear or firmware being like WaveIP's?? Could you elaborate please.
Waverider gear is not changing its PHY layer or MAC layer in any way that approximates WaveIP's implementation--or I'm completely out of touch...in which case, feel free to correct me. Yes they now have a POE outdoor model and have plans to increase throughput to 6 or 8Mbps later this year--but that will involve a hardware upgrade...not just a software/firmware tweak.
Having installed 900MHz for a long time now it should be noted that what my backyard looks like and what your backyard looks like are two completely different scenarios. NLOS is SOOOOO SOOOOO SO dependent on each individual installation. What produces an excellent clean signal quality at one house, might be completely unusable only 200 yards away at the neighbor's. My point being--I have NLOS installs at 4 miles with indoor antennas. And I have installs at 2000 feet that require a 10dBi external yagi. Just want to caution anyone reading about 1.5 or 2 mile NLOS claims...it all depends.
My real question is about the WaveIP gear. And specifically, is there anything about their product (other than the basic laws of propagation at 900MHz) that improve on Waverider's ability to slice through trees and clutter? I will hopefully be speaking with Curt Gordy tomorrow to learn some more. My guess is that the sacrifices (subjective opinion) made to leverage 802.11b PHY technology...will reduce WaveIP product's ability to perform in truly challenging NLOS conditions. I'd love to be surprised though. |

In regards to it being based on the 802.11b I took a look at there site and it said this
"Next generation 802.16a Mac layer
GigAccessTM 900 delivers the highest throughput (8Mbps ethernet usable throughput) by implementing the IEEE new 802.16a MAC layer, which was designed specifically for a Point-to-Multipoint wireless systems.
The 802.16a MAC layer has a sophisticated and very efficient resources management mechanism that can handle dozens of subscribers without wasting precious RF resources for polling or subscriber's questioning.
Using a more efficient MAC GigAccessTM 900 delivers more bandwidth to more customers over the same spectrum and infrastructure which means more revenue for the same total cost of ownership.
Triple layer applications like high quality streaming video combined with VoIP and data connections are now available.
"
Anyone have some real pricing on these things? they look interesting.
