Getting Started with STRIDE Wireless¶

This document focusses on creating and managing a Green-GO STRIDE wireless system using the Green-GO Control software.

Most of the things discussed in this document are also possible directly through the device's setup menu. Please check out the device's documentation for further information on how to setup your STRIDE system without software.

STRIDE vs WAA - What's' New?¶

Although the WAA and STRIDE antennas have much in common and use the same reliable DECT technology, some differences make the STRIDE antenna a much more versatile product. The main differences are:

True Seamless Roaming

There are no audible interruptions from one STRIDE antenna to another during the handover.

Unified Pairing Method

A STRIDE wireless system combines previous pairing methods (OTA, Software), making it much easier to administer and maintain your wireless system. In addition, the pairing process is now quicker and more intuitive.

More Clients per Antenna

When used with existing wireless belt packs, the Green-GO STRIDE antenna increases the possible simultaneous client connections from four to five.

DECT Monitoring

Each STRIDE antenna supports a monitoring mode, enabling the user to scan the DECT frequencies to better understand and analyze the utilization of the DECT spectrum.

User Interface

The user interface consists of a high-contrast E-Ink display and three buttons to allow for on-device configuration without requiring the Green-GO Control software. In addition, the E-Ink display indicates the last active configuration, even if the device is turned off.

IP53 Rating

The STRIDE antenna features an environment rating of IP53, allowing for better weather protection in outdoor installations.

Versatile Mounting

The STRIDE antenna offers a multitude of mounting options (⅜", M10, and VESA 100) to accommodate a wide variety of installations. Additionally, the metal back plate offers a fixation point for securing a secondary safety wire.

PTPv2 Based Synchronization

To better utilize the available spectrum and enable roaming, the Green-GO STRIDE antenna requires a PTPv2 network infrastructure.

Preparations¶

Before starting your STRIDE wireless experience, you should check and take care of a few things outlined in the following chapters.

Control Software¶

Configuring STRIDE antennas and pools with Green-GO Control requires at least version 5.1.0 or higher. You can find the currently used version of Green-GO Control in the bottom-right corner of the startup screen.

Alternatively, you can check the software version while using the application by locating and clicking the settings menu in the top-right corner and selecting the about option.

This will bring up a dialog box featuring the current software version:

Device Firmware¶

You must ensure that your STRIDE antennas and WBPX(SP) wireless belt packs are all running at least firmware version 5.1.0 or later.

Setup Menu
└──> Info
    ├──> ...
    ├──> Firmware: WBPX 5.0.7.9165
    └──> ...

Network Setup¶

Seamless roaming requires a very precise synchronization between all connected STRIDE antennas. Therefore, you need to ensure that all network switches connecting your STRIDE antennas are capable of and configured correctly for PTPv2 (IEEE 1588-2008).

While other Green-GO devices don't have any requirement for PTPv2, it is vital for optimal roaming performance to have continuous PTPv2 support for the network connection between all your STRIDE antennas.

With that said, Green-GO STRIDE antennas work with network switches capable of transparent- (TC) or boundary clock (BC), and there is no requirement for any external PTP master clock as each STRIDE antenna can serve that role.

List of supported (tested) PTPv2 network switches¶

The STRIDE wireless system delivers optimal performance when connected with network switches that provide full PTPv2 (IEEE 1588-2008) support.

Based on extensive testing, we've curated a selection of network switches that deliver good PTP performance and reliability.

With that said, the above list is by no means an exthaustive list of compatible switches but it will be extended as we sucessfully test and validate other candidates.

Device Preparations¶

Prepare a STRIDE antenna¶

There are a few simple steps to get your STRIDE antenna up and running:

Setup Menu
└──> Network
    └──> Dynamic: No # (1)!
        ├──> Address # (2)!
        ├──> Netmask # (3)!
        └──> Gateway # (4)!

Setup Menu
└──> Config
    └──> Join Configuration # (1)!
        └──> Configuration Name # (2)!

Setup Menu
└──> DECT Pool
    └──> Clear # (1)!
        └──> No # (2)!
        └──> Yes # (3)!

Prepare a WBPX belt pack¶

It is always a good idea to reset the DECT module and clear your wireless belt pack pairing before connecting it to your STRIDE wireless system.

With a Green-GO WBPX or WBPXSP belt pack, there are two ways to do this:

Setup Menu
└──> DECT
    └──> Mode: <Pool Mode> # (1)!
        ├──> ...
        └──> Clear Pairing # (2)!

Setup a STRIDE Wireless System¶

A STRIDE wireless system can be created and reconfigured from Green-GO Control by switching to the wireless view. Here, you'll notice some changes right away.

Starting with Green-GO Control version 5.1.0, the wireless view features additional tools to monitor your wireless system and devices, such as the new Home tab above.

However, you will first need to set up your own wireless system or Green-GO Pool. So, head over to the Pools tab to get started.

Create a new STRIDE Pool¶

Edit a STRIDE Pool¶

The Green-GO Control software enables you to change a STRIDE pool at any time. However, you have to switch to the respective <Pool Name> tab to do this.

Clicking the edit button in the navigation bar will bring back the previous STRIDE pool wizard, enabling you to add and remove devices.

Editing a pool allows you to add or remove antennas to adjust its client capacity or coverage.

Additionally, in a second step, adding or removing wireless clients connected via USB is possible. Both actions are immediate and are done by clicking the or symbols in front of the device names.

Client Registrations (OTA)¶

While it is possible to add or remove clients from a STRIDE pool by editing the pool and connecting the client via USB, the new STRIDE over-the-air method is often much quicker. Combined with the new start-up method for WBPX(SP) belt packs, the unpaired client will display a pairing offer that the user can accept to pair and connect the client directly.

However, to do this, you must change your wireless system's Pool Mode in either the Home or the Pools tab.

The Home tab features a card for every wireless system, each providing an ellipsis menu that allows you to change the Pool Mode to Discoverable.

Alternatively, you can switch to the Pools tab and make a right-mouse click in the Mode column of your pool. This brings up a context menu featuring the same options.

After selecting one of the Discoverable options, all antennas in that pool will start broadcasting a discovery beacon for the chosen period of time, allowing unpaired Green-GO clients to connect automatically.

While the discovery is active, all antennas indicate this state by displaying the wireless system's Pool Identifier and a green blinking Green-GO logo.

During discovery, all currently unpaired wireless clients using at least firmware version 5.1.0 or higher will display a pairing offer showing the wireless system's Pool Identifier.

After verifying the Pool Identifier, you can proceed with the pairing by pressing the Button labeled YES. Once completed, the device will automatically try to connect to any antenna within reach, with at least one free slot for client connections.

You can disable the client registration for all antennas at any time by switching the Pool Mode to Closed or Open. Both options are fine; however, choosing Closed could lead to undesired connection issues, as each antenna now only allows known clients and any previously removed client will be rejected.

Monitor Your System¶

The Home Tab¶

The Home tab, located in the wireless view, is a convenient alternative to a dashboard providing a detailed overview of all your wireless systems.

Each card displays a detailed overview of the system and its devices. The top-right ellipsis menu on each card provides options for further control over client registration.

The layout for each card consists of a table that lists all clients along the x-axis, displaying statistics about the connection and access point used. The antennas are on the y-axis, indicating their respective client count, PTPv2 state, and the state of its synchronization.

PTPv2 Connection Status¶

Starting with version 5.1.0, Green-GO Control provides real-time monitoring of the PTPv2 timing synchronization between STRIDE antennas and the PTP master clock. This synchronization is crucial for seamless roaming functionality across multiple antennas.

To monitor the PTPv2 synchronization of your STRIDE antennas, open the Green-GO Control software, navigate to the connection view, and select the PTP tab.

The tab displays a real-time PTP timing offset graph that visualizes timing deviation measurements between the local clock of your STRIDE antennas and the system's PTP master clock over time.

The horizontal (x) axis shows the time progression over the last 60 seconds, while the vertical (y) axis displays the deviation between the clocks measured in microseconds (μs).

The visualization includes three colored zones (green, yellow/brown, and red) to indicate different quality thresholds of synchronization performance.

Interpreting the Results¶

The PTP timing offset graph displayed in the PTP tab uses three distinct zones to indicate synchronization quality:

• Green: Good sync (max. ±1 μs)
• Yellow: Critical sync (max. ±1-2 μs)
• Red: Unsync (max. >±2 μs)

A well-functioning system maintains a stable line within the green zone, indicating less than one microsecond of timing deviations. This level of synchronization ensures seamless roaming between antennas without audio interruptions.

Once the measurement line enters the yellow zone, the potential for problems with seamless roaming increases, mainly causing minor interruptions during handovers between antennas. Short spikes could occur with natural events, such as a switchover to a different PTP master clock.

However, if these excursions into the yellow zone persist over a more extended period or are constantly occurring, an investigation of your network infrastructure is recommended.

Poor synchronization manifests as an erratic pattern with frequent excursions into the red zones.

The example above shows large timing deviations well exceeding the recommended limit of ±2 μs, which will cause noticeable audio interruptions and increase the potential for client disconnects during handovers.

Such a state of PTP synchronization heavily impedes your system's roaming performance and is most likely the result of missing PTP switch compatibility or network misconfiguration.

Troubleshooting¶

My antennas don't get a good PTP synchonization¶

If you're experiencing unreliable PTP synchronization, you should start by verifying the following:

• All network switches between your STRIDE antennas fully support PTPv2 (IEEE 1588-2008).
• Your switches are correctly configured for either transparent- (TC) or boundary clock (BC) end to end (E2E) operation.
• Avoid mixing PTPv2 implementations from different vendors, doing so could lead to unexpected timing issues.
• Load the factory defaults for the PTP configuration of all your STRIDE antennas.

Additionally, consider the complexity of your network topology – fewer network hops between antennas generally result in better synchronization performance. High network loads or interference can also impact timing precision, so monitoring these factors may help identify the root cause of synchronization issues.

How to load PTP default configuration¶

To load PTP default configuration, you can either use the device's setup menu, or use Green-GO Control switching to the connection view where you can edit the device's PTPv2 configuration.

Setup Menu
└──> PTP
    └──> Load Defaults: No # (1)!
        ├──> No # (2)!
        └──> Load # (3)!

One of my STRIDE antennas uses an incorrect PTP master clock¶

If you experience a problems with PTP master clock negotiations, you may want to check and verify the following:

• All STRIDE antennas use the same PTP Domain in their PTP configuration.
• Your network infrastructure does not limit, slow down, or block any traffic between any of your STRIDE antennas.
• Load the factory defaults for the PTP configuration of all your STRIDE antennas.

I get a "hard" disconnect instead of roaming seamless¶

Such an issue should only arise if consistently bad PTP synchronization is present or an unexpected power loss occurs with a Green-GO STRIDE antenna actively serving clients.

Please verify the device's cable connection and the stability of the PoE supply to the device.

Why is the E-Ink display flickering?¶

The "flickering" is a side effect of the E-Ink technology used for the display. The "flickering" usually occurs after two major screen changes (e.g., entering and exiting the setup menu) and needs to occur to refresh the display's pixels and avoid any ghosting of previous display content shining through.

How can I change the PTP master clock device?¶

The election of the PTP master clock happens during boot time and is influenced by the device's MAC address and its PTP configuration. A re-election usually only occurs on network splits and/or a disconnect of the currently locked master clock.

To force a specific STRIDE antenna to act as PTP master clock, you can configure the PTP Priority 2 in the device's network settings. Afterward, a power-cycle of the current master clock ensures proper re-negotiation.
