Motorola AP-7161

With so many projects going there has not been much time to write about them and the interesting things being learned (as well as mistakes to avoid). Of course the one project that I have not had time to work on is how to clone myself so that I have more time for all these projects.
Currently helping develop a code plug to work on a Mototrbo ConnectPlus system without having a live system to test it on and then learning that the new Aeroflex 3920 Digital Test set cannot emulate a Mototrbo ConnectPlus system…but been told they (Aeroflex) has thought about it.
Trying to see if there is a clean way to have a Kantronics KPC-9612+ monitor the temperature of four outdoor cabinets so I know when a cabinet air conditioning unit has failed and if I can find a way to do this then I can have use of it as a high (900 ft) digi 🙂
Another project is sorting through over 100+ online manuals to piece together enough info to put together a simple OTAP (Over the air Programming) system as well as get a better overall understanding of Motorola Astro25 Conventional CORE. ( think I am going to need Lt Cmdr Data’s positronic brain for this one)
Learning and understanding inSSIDer & Channelyzer Wi-Fi tools to “wardrive” the terminals to map all the AP’s sharing the 2.4 GHz air space with MotoMESH and now have a better understanding of the channelization and how Channels 1, 6, and 9 are the only non-overlapping channels and that having an AP share the same channel is better than one on an adjacent channel.
Hopefully I can free up some TDM slots to expand more on these and other projects….but for tonight I am working on and learning these AP-7161 AP’s.


This is a PoE device and has 3 radios: 2.4, 5.8, and sensor radio for wifi monitoring. The three like antennas on top are the 2.4 GHz antennas. The three like antennas on the bottom are the 5.8 GHz antennas. And the one long antenna both on the top and bottom are dual band antennas for the sen


The LED’s indicate the status of the three radios, Ethernet port activity of the PoE and Ethernet ports and the health of the unit as its “adoption” status. What I have learned so far is that the controller for these units “adopt” the unit when it’s turned on, push its programming/provision the unit over the air. Also, the AP itself can be set up to be a virtual controller for up to 24 units. But for this particular application only one AP is being setup to test a couple of Motorola ET1 tablets with the customers apps.


Since the 2.4 band is already full we will be testing these tablets on the 5.8 GHz band. Since these are Enterprise devices we quickly learned their limitations as far being allowed to install the apps we wanted to use to monitor the connectivity and other performance tests. So going to have to get creative with the tools we wanted to use.

Well, there is still much more to learn about these devices and hopefully they can be used to replace all of the existing Solo and Duo AP’s but that is a ways off. Hope to try to be more active with updates on these and other new projects and maybe get some feedback or ideas or sources of good info. Well now to get to work….until next time….73s!

Digital Radio Protocols

I know it has been many clock cycles since I last made a post here but hoping to have more to post here during the next couple of months as I endeavor to get a better understanding of the different digital radio formats and protocols being used, especially the ones I am having to work with on a daily basis.
Here later with the influx of many projects at both my real job and part time job I am having to get an understanding, in addition to Astro 25 I now have to learn and understand Motorrbo. And since I have always had an interest in D-Star I figure I would include this also. I am also having to understand Digital Spread Spectrum now as we’ll, which should be interesting just from how Spread Spectrum propagates from the preliminary info I was given.
So this will be the first of what I hope will be an informative ride into digital radio and get a good and better understanding for myself as well. There are some things I am hoping and wanting to do and hoping as I gain a better understanding I can see if what am I am wanting to do is already inherent within the protocol. One I already know exists in both Astro25 and Mototrbo and interested in getting a better understanding is OTAP (Over the Air Programming) which would make updates less labor intensive once setup.
So, as I gather up the info there will be more posts here along with photos where possible. Until next time….73s!
