Will changes to cellular service disrupt your treatment operations?
What you need to know.
Verizon Wireless has announced their transition to 4G LTE technology for all IoT (internet of things) devices communicating on their wireless network. In a customer letter dated November 15, 2017 Verizon wrote:
"On December 31, 2019, Verizon plans to retire its CDMA network (1x/EVDO, 2G/3G), and we will stop activating new devices on CDMA after June 30, 2018."
Who is affected?
Any water/wastewater utility operators who rely upon monitoring and control of remote sites that do not use radio or landline communications will be impacted. After December 31, 2019, sites that utilize CDMA for communication will no longer function properly. The devices affected are typically data modems. A commonly used 3G modem is the Sierra Wireless LS300 like the one pictured below.
What needs to be done?
Verizon Wireless has provided a reasonable schedule for their transition and no immediate action is required. However, these older 3G devices will have to be replaced prior to the 2019 deadline. We recommend these two actions:
Check your remote sites for existing cellular modems. Record the make and model number and “google” it or call us to determine 4G LTE capability.
When existing CDMA devices need to be replaced or if new systems are to be brought on line, only 4G LTE capable devices should be purchased and installed.
How is Instrulogic responding?
We are already supplying only 4G LTE capable modems for all new installations and no longer supply devices that are not 4G LTE capable. We have experts available to help plan and implement your migration from CDMA devices to 4G LTE.
