I know this is a common question but I am wondering how to increase range on my Lora 'LoStik' device. https://www.crowdsupply.com/ronoth/lostik
I am trying to send data from one LoStik to another. Both are plugged into Raspberry Pis. Data packets are small, maybe a string of 50 or 60 characters.
The data sheet claims around 15 km, but I can barely manage 2 km. I have read up on spreading factor and have increased both Spreading factor and the Tx power to the maximum.
I am beginning to think I will need to use a different type of antenna to achieve maximum distance. Is this correct? What type of antenna should I use?
Aside from that, what else can be done to increase Lora Range? I am using two LoStiks to communicate with each other to simulate (on a small scale) the deployment of cheap Lora hardware. Should I be focusing on different hardware? Is it more efficient to setup a LoraWan gateway than having a bunch of LoStik end nodes talk with one another?
I haven't even begun to consider security issues....
Thank you for the help!!
