How to create a viewshed in Cambium Linkplanner 5.3.0

Viewsheds are a feature present in the Online Map (using V5.3.0 or later), which indicate all the locations in the area surrounding a chosen place that are considered to be Line-of-Sight for a given tower height and subscriber height.

Cambium 450 16.1 release notes

System release 16.1 adds support for:

• Proportional Scheduler
This release introduces proportional scheduler that allocates resources to SMs proportional to their plan, even when traffic is congested
• Auto Contention Slots
This release introduces Auto Contention Slots that eliminates the need to configure optimal number of contention slots. When this feature is enabled, AP dynamically adjusts the number of contention slots resulting in improved uplink performance. • Error Vector Magnitude (EVM) Measurements
• EVM based Link Quality Indicator (LQI)
• Last Known Primary AP
• Follow Me
• 802.1x Proxy
• Layer 3 PVID Mapping
• Custom DHCP Option 82
• 802.1p VLAN0

 

LibreNMS and Cambium Networks

What Can Libre do for the Cambium operator?

Number of registered SMs. This AP has 7

 

Interface traffic

Number of GPS Satellites tracked

Modulation

Libre can be setup for thresholds.  Any of the above graphs can be set up to alert based upon a threshold.  You could setup an alert that says if SMs on an AP drop by 10% kick out an alert.  This could alert you to possible frequency issues.   You could set a threshold for if traffic reaches a certain level.

Cambium ePMP 3000 features

An older post but still relative. Figured I would re-post this.

Cambium and CTIconnecxt put on a webinar about ePMP 3000 today.  This should be available online at one point.  Look for it in the Cambium forums.

Some notes I took
-ePMP 3000 offers Simultaneous MIMO downlink transmission
-You will be able to use the beamsteering antenna with the 3000.  Cambium is working on the software to make this work.
-3000 has a dedicated receiver chip.  This allows you to run the spectrum analyzer in realtime. Also has “edetect on steroids” which shows more information than the current edetect.
-Sector is a 4X4 90 degree sector with beamforming. Achieves and extra 3db in the downlink.

Beamforming vs Beamsteering
Beamsteering is for dealing with interference.
Beamforming is for downlink gain.

-Cambium mentioned the concept of Azimuth Delta.  This is groups of SMs in terms of how the AP talks to groups.  The gave an example on a google earth plot.  In a nutshell, when you have gain in one direction it takes advantage of the null in different directions. More to this, but that is for another post.

-“Sounding” -Sends a special packet and gets feedback from the subscriber. Determines how the phase shift works and other things.

-Elevated clients beta is coming to make the elevated clients work with the 3000.

I hope distributors work out a smaller cold shrink for the sma connectors on the ePMP Ap radios.  Weatherproofing these properly will be an issue due to the close proximity of the connectors.  I have not seen the connectors on a sector to see how those will be.  This is where folks could take a page from the coldshring that comes with the Baicells gear or the cables with the integrated boot some distributors sell.

 

Cambium announces CBRS SAS service for PMP 450

From their release

Cambium Networks is pleased to announce the commencement of the CBRS SAS Services, providing service in in the CBRS (Citizens Band Radio Service) spectrum (3.55 to 3.7 GHz). Support is offered on the PMP 450 series platforms utilizing the cnMaestro management system. 

There are several SAS System Administrators that are in operation today. Cambium Networks will work with three of them; Federated Wireless, Google and CommScope*. The operator will select one at the time of sign up via cnMaestro. The pricing to use these SAS Services is the same regardless of the provider.  Pricing will be $3 per Subscriber Module per month. (There is no charge for the Access Point).
