Mashup using Wiana and Google Map API's

A mashup is electronic content from more than one source via a public interface or API, Web feeds (e.g. RSS or Atom) and JavaScript, that when combined in an innovative way and presented with active user participation and interaction creates a new website, view or service. The greater availability of simple and lightweight APIs have made these web applications relatively easy to design. They require minimal technical knowledge are sometimes created by innovators, combining available public data in new and creative ways.

The term almost certainly derives from its similar use in pop music where Disk Jockeys (DJs) would, edit using electronic equipment take the vocal track from one song and combine it with the instrumental track of another song resulting in an entirely new composition.

Mashups, though they have been around since the first API was released, have begun to garner more media attention since the beginning of 2006 due to many web companies beginning to fully embrace technologies that enable many people (and more specifically web developers) to easily interface with the primary company’s intellectual property. A good example of this would be Google creating the Google Maps API and letting anyone utilize their Google Maps software and databases so that individuals can develop many new and creative uses for the mapping software.
Using Locustworld’s WIANA.org and Google Maps I have been able to illustrate wireless Mesh nodes. Unfortunately as I change out the nodes the maps do not automatically update the position. One need to provide the Latitude and Longitudinal coordinates in Wiana. Once this is done the illustration of position are automatically updated. Moskaluk wireless mesh nodes (MeshAP).

Check this out

When I first started to experiment with Mesh hardware I had great support from David Peterson. In the early days I could email Dave and he always came up with a solution for me. So I always look up to his group. Back when it was known as Ultramesh I even help Dave with his website. Well David move to Defacto Wireless and now I see that he is the CTO of Airmatrix. Wow Dave you sure move up from selling me Prism based wireless cards. And no he didn't sell me the ones that I currently having problems with ( I was very cheap in those days and bought them off ebay.) My wife corrected me I am still very cheap. I saw a new website call Airmatrix and noticed that he had a link to my blog. Wow AirMatrix said something good about me. I thrilled. Good luck in your new adventure Dave!

Showing the wear and tear

It seems like in last 3 weeks I have change 4 different MeshAP. They all had the same symptons:

Radio Card was hearing a lot of noise
Radio Card power was weak
Software did not have the ability to mesh

It seems that the radio cards that I used 3 years ago were low power Netgear type PCI cards. I configure them in Wiana to be either auto power or I increased the power to 200 mW. It didn't mater if I ran the cards overpower or in normal the cards are starting to fail. And it is really funny that they are all failing with in weeks of each other. Is it to do with the their environment? I don't have enough data or expertise to determine why these radio cards would start to fail.

If the radio cards are failing then I would have to add a maintenance program that would go and visit each MeshAP once every 30 months to replace the radio card. I am now wondering the commercial units. Do they have the same problem?

Old Units still has life

Well after looking at all my 2003 made units I amazed that old discard PC are still running today! The radio cards are starting to fail and as soon as I replace the radio with new units I can see that most of my problems were in the weak transmission of the radio cards. What I am really amazed that the old Compaq computer have been running 3 years now in the outdoor temperature under extreme heat and cold conditions. If they are running they should have no problems. I did however had some problems with container or units that were totally exposed to the elements. But to some up old PC are still working. Replacing radio card for a new version does not seem to be a problem!
