**_ypinckovich: I am not much of a radio specialist but received a request from a client for some radio equipment which we are quoting with for connecting M340 plc with 2 satellite stations._**
**_We are quoting the JR900 series. If I am going to have HMIGTO and HMISTU units (6 of each) spread out over 3 locations (main building, 2 satellite panels 200 feet away), will the bandwidth be sufficient to not have much or any lag in information update?_**
**_The satellite panels will contain a couple distributed I/O with Ethernet capability and will connect to the TBURJR90000002EH0. We are choosing between TBUM297224 and TBUM297287 antennae (not sure how much power is required yet). Also, at each satellite and central panel, we will have 2 of each type of HMI panel._**
**_Thanks in advance for the help, Yarom_**
du5tin: From the brochure the JR series can have a maximum over the air bandwidth of 512kbps, with 256 kbps being the default. Your latency time will be dependent on a lot of other factors though. At 256 kbps the typical latency for a single packet is under 100ms.
