基于Da1458 Da14580定制板3 Smart Bond design

hi Dialog

We have designed a custom board with DA14580 ( 3v coin cell battery )based on Da14583 IOT design , everything is similar lyk antenna design (IFA antenna) , but IOT Board gives range around 10 meter , But our custom board gives hardly 6 meter range only , why ??

If i use range extender how much range i can achieve ??

Thank you

Hi prasanth,

Hi prasanth,

The range of an antenna depends on many factors, matching, type of the antenna, pcb layout etc, also the IoT design uses a ceramic antenna and not a IFA antenna (we used the IFA antenna symbol in order to emulate an antenna in the schematic, but a ceramic antenna is used, as the application note UM-B-064 documents). Regarding how long you can go with the range extender, with the current perfomed tests we could achieve communication up to 400 meters.

Thanks MT_dialog

Hi prasanth,

Hi prasanth,

I can arrange in sending you one if you are interested in the reference design, you can also find the details of the module in the corresponding application note UM-B-045 User Manual Range Extender version 2.

Thanks MT_dialog
