Let's Talk SNR

The Signal-to-Noise Ratio (SNR) is one of the most significant factors that control the speed and stability of your link.

Signal: In nearly all cases - there is nothing you can do to boost the signal as it will be set to the maximum legal limit anyway. Your hands are tied here.

Noise: This is any sort of radio noise - including neaby WiFi (maybe your own!) - that interferes with your signal. This you CAN do something about - and it is simple.

For example, keeping the signal level unchanged but reducing the noise level by just 3 dB can result in a speed improvement of a massive 50% on Ubiquiti airMAX products.

So how do you reduce Noise?

Simple ... add a Shield Kit from RF Armor. These are metal shields made of marine -grade aluminium (no rust) that are made to fit almost all Ubiquiti outdoor products.


This picture shows a  Ubiquiti NanoBridge with an RF Armor shield kit.

It takes about 60 seconds to attach, with just a phillip's head screwdriver.

So what do RF Armor customers say?

It's really amazing how much these help reduce the noise. To boot I believe the shield helped save one of our radios from a direct lightening strike on one of our towers. Every other radio died, but the nanobridge is still trucking along.

All my Problems are gone after installing this sector kit. Very good product. My client is happy.

We installed RF Armor shielding kits on 7 ubnt sectors ontop of a 90' silo. We were having problems due to some of the APs being in close proximity of each other. After installing Chris's shielding kits our performance was significantly increased! We are in deploying another POP on a Silo soon and will be ordering shielding kits again! Thanks Chris for your excellent design!

I have been a WISP since 2007 and in the last year have implemented the use of RF Armor Shielding at all of my relay and tower sites. I have found that the use of their product has allowed me to make 40% more use out of the license free spectrum by reducing outside noise and interference from other sites. In addition to providing more efficient spectrum use, I have also noticed higher and more stable over the air data throughput.
I have found the design and engineering to be of the highest quality and the ease of application well thought out.
If you are considering the use of the RF Armor products the only thing I can tell you is that we should have all done it long ago and having a site without it is a mistake.

Having to connect two residences approximate 3/5 of a mile (1 km) from each other through minimal bushes/trees, I found that a 5.8 GHz link using a Nanostation M5 on one end and a Nanobridge M5 on the other actually linked up, but didn't have the best signal strength. I've browsed the forums for a while and always saw the RF Armor product, but didn't attempt to try it until now. I purchased one kit for the Nanobridge end, and the results were hard to believe at first. I'm and believer and have just ordered 5 more kits. Amazing product.

We don't deploy a Ubiquiti sector without a RF Armor shield kit.

UniFi VoIP Phones - in Stock now

UVP Ubiquiti is now shipping the UniFi-VoIP Phone (UVP).

We have tested these with our favourite SIP VoIP provider and they work great. You do NOT need to connect them to a Ubiquiti SIP PABX - they are industry standard so work with any SIP provider.


But what makes these phones stand out from the crowd is one very simple thing - Android.


You can customise your deskphone with apps from the Google Play Store. I just love mine for that reason.

If you are already an Android user, then you will understand that simply by logging into your Google account (once only), your Ubiquiti VoIP phone now has ...

  • syncronised with all other Android phones/tablets you have on the same account.
  • all your contacts. This is a huge feature as it has all the phone numbers and email addresses.
  • all your Google Calendar events/appointments, so it beeps for your appointments.
  • access to your Gdrive (free cloud storage).
  • Google News.
  • and so many features in the Google eco-system.


  • The UVP-PRO (with WiFi, Bluetooth, and camera). Arriving soon.
  • The UVP-Exec (like UVP-PRO but with bigger 7" screen).
  • A soft-PBX. Ubiquiti will be releasing free VoIP PABX software very soon. Free meaning: "Free" and "no licensing costs". So you can have your own PABX in each office branch - with free calls between them, and cheap in/out calls to the PSTN (Public switched telephone network) via a SIP provider (there are many in Australia).

What to test the quality?

Online Training


UniFi Training1

UniFi Training2

In a world's first, Online training (developed in Australia) is now available for the Ubiquiti products shown.

You benefit  in a number of ways:

  • Cheaper - than attending a formal 2-day course in a classroom environment.
  • Faster - no need to wait until the next classroom course is scheduled nearby.
  • More convenient - the self-paced courses can be scheduled around other demanding work.
  • More practical - the Ubiquiti classroom courses are great for students needing to delve deep into theory such as Radio Waves, Antenna design, TDMA protocols, Link-Budgets, UniFi-WiFi site surveys, etc. But in many cases, students just want to know how to setup some very common scenarios. These Installer courses are targeted with less theory and more practice.

The way each course works is ... each student:

  • signs up and receives by email a set of detailed course notes. These can be kept as a reference document for use later on-the-job.
  • is allocated real test hardware for 7 days. This is hardware the student gets to configure (over the Internet).
  • passes an online quiz for each module. When all module quizes have been passed, the student gets emailed a Certifcate of Completion.

Classroom Training

airMAX and UniFi

We have both airMAX (airOS), and UniFi training courses available. The courses are each 2-days, and are booked separately. But in most cases, we will schedule them back-to-back so students can attend both in a 4-day stretch.

Upcoming scheduled courses:






Perth 2015 Mar 24-25

 Talked the boss into updating our APs to UniFi from Cisco

When we added on to the building again, I had the option of buying another Cisco AP for $350 (maxing out our controller), or selling the Cisco stuff, and buying all new Ubiquiti gear....
