The main task when designing an automated metering system is to choose the right communication equipment that will provide a stable communication channel and uninterrupted operation under any operating conditions. It is equally important that it is reliable, safe, mechanically protected and easily integrated with existing metering units.
At this stage, difficulties arise with the choice
The communication standard, according to which the modem operates as part of the ASKUE. What is the problem and how to solve it? The specialists of EMR LLC tell us.
Problem
Recently, we have noticed an increase in the number of saudi arabia phone number list requests to technical support with complaints about the availability of ASKUE equipment due to communication problems. The reason is the transfer of information from the end equipment via GPRS connection through 2G modems. We have studied the requests and found out that small problems with the quality of the Internet connection do occur from time to time.
The instability of the connection is due
The limited coverage of the 2G network and the low bandwidth of Internet traffic. The problem arises as a result of the modernization of cell towers, as how to automate or schedule whatsApp messages operators abandon the slow 2G connection and switch to newer technologies. Many cellular networks no longer have this standard, although there is still a 2G signal. In this regard, we can increasingly observe situations where the modem is online, but there is no information transfer.
The question arises: how to solve the problem of Internet connection in 2G networks?
So, we are faced with the issue of unstable connection singapore lead of 2G modems in the ASCUE. Using such equipment, it will not be possible to cope with the problem. 2G technology is outdated and will soon be replaced everywhere by more modern 4G and 5G standards. In addition, 2G modems transmit information over an open channel and expose the ASCUE infrastructure to serious danger.
The problem can be solved by using a specialized industrial LTE modem. An example of modern equipment in this category is LTE (4G) modems and Teltonika gateways . The devices operate via secure VPN channels and make interference in the AMR impossible. The speed of LTE modems reaches 10-150 Mbit/s, they have compact dimensions and low weight, a wide power supply range and low energy consumption.
By replacing outdated routers with modern external LTE modems
It is possible to eliminate problems with the availability of ASKUE equipment, ensure a high-quality and stable connection to the Internet, and avoid interruptions in data transmission.
It is equally important to touch upon the issue of the cost of new equipment. With the development of modern technologies, it was possible to reduce the cost of an industrial LTE modem chip and increase its availability to a wide range of consumers. The difference in the cost of a modern modem and an obsolete one does not exceed 30%. Considering how LTE modems work, this can be ignored, since the differences in price are compensated by their functionality.
