Improving Gateway Reception

If your machine is showing intermittent segments of lost data, your Gateway may have poor reception. This article will help you identify a Gateway with poor reception and the ways to resolve this issue.

Diagnosing Gateway LED's

Amper Gateways will have LED's on the front face that will indicate the device's current status. Examine the signal strength LED (top for Wi-Fi, bottom for Cellular) for the following colors:

  • Green - Good Signal Strength
  • Yellow - Moderate Signal Strength
  • Red - Poor Signal Strength

Red LED indicates you will need to adjust the position of the gateway in order to achieve better reception. Continue reading for the best practices to improve signal strength.

Adjusting Gateway Position

The simplest way to improve your gateway reception is to adjust the location of the device until the signal strength LED improves (Red → Yellow, or Yellow → Green).

  • Mount the Gateway as high as possible so that nearby machinery is less likely to break the line-of-site from the Gateway to the cell tower or Wi-Fi access point.
  • Move the Gateway to a different location around your machine (e.g. to the opposite side of the machine).
  • If there are other Gateways nearby with better signal strength, consider running the CAT5 cable over to that location.

Poor Cellular Reception

Some factories are located in an area that has generally poor cellular reception and measures beyond adjusting the Gateway's position will be necessary.

  • If the Gateways can connect in other parts of the building or immediately outside the building, run longer CAT5 cables to those locations. Cable runs up to approximately 100m are generally fine.
  • Install cell signal boosters onsite. The Gateways have the ability to use both T-Mobile and AT&T 3G cellular service. Installing a compatible cell signal booster may increase signal strength enough to work well.
  • Swap out Gateways for Wi-Fi Gateways. We're more than happy to do an exchange and replace your Cellular Gateways with Wi-Fi Gateways, at no cost to you. Review our article IT Configuration for Wi-Fi Gateways for more information on the requirements needed to connect Amper Gateways to your local network. To make this swap, please contact your Customer Success Manager for more information.

Issue Continues to Persist
