Big Changes Coming to Ubiquiti Certification Classes

In this video, I will be discussing some exciting updates for our Ubiquiti certification classes, specifically for the UEWA and the UNS. We are transitioning to a new approach where we will provide each student with a dream machine instead of relying on software installations on their computers. I will explain the benefits of this new paradigm and cover various routing, switching, and application capabilities introduced in the UNIFI line. Additionally, we will explore UNIFI Protect, camera systems, door access, UNIFI Talk, and UNIFI Connect. Lastly, I will introduce the new Wi-Fi MAN tool and request that you bring your own device to class.

An interesting update on the percentage of users in the three different spectrums

When 802.11ac was introduced in 2013, some Wi-Fi engineers predicted that the Wi-Fi industry would quickly move away from 2.4GHz and start using the 5GHz spectrum, and, although there has been a steady transition, 2.4GHz still holds a rather large portion of the pie.

Remember, there are only three 20MHz non-overlapping channels in 2.4; channels 1,6 and 11, while 5GHz has 25 channels to choose from.

6GHz offers even more channels to choose from, but the FCC only allowed for it’s use in 2020. It looks like the early adopters have jumped in, but what will happen to the 35% of users still using 2.4?  It seems like we will be supporting it for a long time to come.

Ubiquiti’s New WIFI 6 ONU

Ubiquiti’s New WIFI 6 ONU

 

 Ubiquiti is expanding its WIFI 6 technology and now is including its ONU devices. The UF-WIFI6 is the latest generation ONU for the GPON UFiber Family and is only compatible with Ubiquiti’s UFiber OLTs.

It includes a USB-C power adapter, but it can also be powered by Passive 24V PoE (injector not included) for ease of installation at any part of the building or house.

This device offers decent WI-Fi Coverage, mainly in 5GHz due to its 3dBi antenna gain.

Webinar: What’s New with UniFi APs, and How Do I Choose?

The “What’s New with UniFi APs, and How Do I Choose?” webinar was hosted by DoubleRadius on Nov. 30th, 2022. The presentation was made by wifi-U as special guest. A review of security gateways, controllers, and switches is followed by an AP comparison including AC Wave 1 & 2, ceiling mount, in-wall, mesh, HD & XG models. WiFI-6 802.11ax is covered towards the end, and the primary improvement of OFDMA.

Broadband Training at Microseismic

Recently I got a chance to teach the Ubiquiti Broadband Wireless course to a group of engineers down in Houston, Texas. MicroSeismic deploys a type of underground radio probe that helps oil companies find oil deposits fractures. Their technology relies on very low frequency radio waves that penetrate the earth’s core for many miles.

They use the Ubiquiti Airmax AP’s to create a large grid that connects multiple probes and allows them to manage all the devices throughout a deployment area.

The probes go down approx. 200’ in the ground and then have a control box that can connect into a switch that the Airmax AP is also connected to.

We spent two days reviewing the AirMax AC devices and the M series AirMax APs. The company uses both, as sometimes they need to use 2.4GHz devices in their large territory deployments. We went through how to do Point to Point and Point to Multipoint connections with both technologies and worked on how to have the clearest signals on long distance connections.

For Microseismic, the data they are transferring isn’t very intensive, so we talked about the advantages of smaller channels and how they are less prone to interference. We had a great time testing all their different equipment and making it work. The guys were real easy to work with and I felt like we accomplished a lot, and I had a great time learning about their underground wireless technology!
