ATOP SE5201B-M1 IoT gateway offers multi-mode connectivity, supporting the 3GPP Release 14 protocol standards (LTE Cat M1/LTE Cat NB2/EGPRS). In an LTE Cat M1 network, it can achieve a maximum uplink speed of 1119 kbps and a maximum downlink speed of 588 kbps. Featuring low standby power consumption, schedulable power management, high EMC protection, wide-temperature operation, dual SIM failover, and rugged metal housing, this gateway is ideal for IoT applications that demand environmental resilience, redundancy, and power efficiency. 
Low Standby Power Consumption The SE5201B-M1 is ideal for a wide range of low-throughput, ultra-low power consumption applications, including industrial sensors and smart metering, agriculture automation and more. These devices periodically wake up to transmit small amounts of data before returning to sleep mode. Designed with efficiency in mind, the SE5201B-M1 also helps you save on monthly ISP fee. 
Expandable SD Storage SE5201B-M1 reserves the flexibility to extend its storage capacity through a built- in SD slot, so you can store more data on the IoT gateway for work efficiency as well. 
Exceptional Security Integrating Firewall, Zone forwarding, and VPN functions, ATOP SE5201B-M1 allows you to connect your industrial network to the internet without fearing intrusions to your organization data. 
Endurance of Harsh Environments ATOP SE5201B-M1 is proven to run at its maximum loading in the harshest EMC and climate environments. APPLICATION CASE 
As a Low Power Consumption IoT Gateway SE5201B-M1 can act as a low power consumption gateway. Through its smart power management mechanism, the device switches to sleep mode or hibernation mode during non-service phases, and can be woken via scheduled management policies to serve functions when needed. It is especially suited where power supply is limiting, such as in systems powered by solar batteries. 
LTE-M 450MHz IoT Gateway for Suburban, Indoor, and Basement LTE Signal-Challenged IoT Applications Introducing our advanced SE5201B-M1 LTE-M 450MHz IoT Gateway, designed specifically to address LTE signal challenges in suburban, indoor, and basement environments. This powerful gateway ensures reliable connectivity for your IoT applications, even in areas where LTE signals are typically weak or unreliable.
