Today let's chat about these 4G industrial routers from yeaplink. Don't be fooled by their small size - these little guys pack a serious punch! Old Mao here has used plenty of industrial routers in his day, but these models really caught my eye. SR500: The Swiss Army Knife of Industrial Routers Let's start with the SR500. 128M of big memory and 16M flash, this baby runs smooth as silk. Dual network ports - one WAN and one LAN - give you network backup both ways. The most impressive thing is its ultra-wide operating temperature range. From -35°C to 75°C, this thing keeps on ticking even if you toss it in the freezer! I had a customer using it at a factory way out in the boonies. No more worrying about network outages - productivity shot through the roof! SR600: The Jack of All Trades The SR600 is even more of a beast. 5 ports to use however you want, flexible networking options galore. VPN protocols out the wazoo, remote monitoring is a breeze. One customer used it for remote monitoring and never had to send someone on-site again. Saved a ton on manpower and resources. SR700: The Speed Demon When it comes to speed, you've gotta talk about the SR700. Dual industrial-grade 4G modules, dual SIM dual standby, seamless network switching. Processor upgraded to 256MB - that speed is downright insane. It even supports WiFi 6 with theoretical speeds up to 9.6Gbps. That's enough speed to last you a lifetime! SR800: The 5G Powerhouse The SR800 takes things to a whole new level
