Hi all.
I am making a custom PCB with nRF51822 SoC. For my project I need to achieve long Proximity range around 350 Feet. Where my Board will communicate with iPhone.
I know to get max range good Antenna RF tuning is needed and in this Developer zone there are some more related discussion. I reviewed those.
I have some queries:
-
Is it really possible to get around 350 Feet range using nRF51822?
-
Which antenna type will be best choice? Chip Antenna or PCB trace? Though there are several types of PCB trace like Inverted-F-Type and some other.
-
In BT classic theory power Class (1,2 and 3) is an issue where I know Class 1 can give more than 100 meeter. So in BLE Class (1, 2 and 3) also involved? I can not use Class 1 and my Board need to be low power running from regular Cell Coin Battery.
I found some Module. Example RFduino. And its memento it can support few Hundred feet. But the Module uses Chip Antenna.
Please suggest me what is the way to get best range with minimum power consumption.
Thanks in advance.
Regards.
