Hi,
We have tested IoT Sensor board with andriod app. It works upto 5 meters range in line of sight.
我们正在设计定制与da14580董事会but we expect range upto 30 meters in line of sight. We planned to provide SMA type antenna connector on board.
So my question is what will be the range covered
1. if we do not connect RF cable to SMA connector and no external antenna i.e. only SMA connector will be assembled on board?
2. With RF cable connected to SMA and external antenna to it?
Device:
Hi,
I also tested IoT sensor board and it works upto 5 meters and our requirement is, to support at least 30 meter. which antenna circuit either PCB antenna or external Coaxial switch ( without connecting Ext antenna ) is better to increase the range upto 30 meter or Is there any design on RF side to increase the range upto 30 meters
Hi Karthikeyan S and prasanth.velliyangiri,
We are performing tests regarding the problem on the IoT kit and the range of the antenna, the hardware team is working on it and examines alternative solutions. I will let you know as soon as i ve got an answer from the experts. Also can you please try to replace the battery on the kits, we observed reduced range in some cases, and if the problem persists can you please give us the bd addresses and the RSSI indicated by the IoT application.
Thanks MT_dialog
Dear Sir,
We have Murata development board with Type ZY Daughter board. It is using DA14580 and this board supports up to 30 meters so what circuit we have to incorporate in our schematic to achieve the same. Kindly support in this issue.
Hi Karthikeyan S,
The Murata module is using a ceramic antenna in their module and i suppose that they have guidelines for the used antenna. Now in the AN-B-027 document in chapter 4 there are general guidelines in order to implement an antenna. According to our hardware team even a printed properly matched antenna has the capability of covering 30 meters range and an even longer range up to 60 meters.
Thanks MT_dialog
