The problem you are seeing may be interference as you suspect. The spread spectrum modulation should help with interference rejection but range of useful operation can be reduced as the other wifi signals
A directional pattern is needed to DF (direction find) a received signal with just a single antenna. Sometimes the antenna is rotated mechanically or electrically to find the maximum signal level. For
Hello John There are a number of approaches to build your wireless sign controller application. One simple way is to get a pair of modules which link the RS232 via radio. You can search for "wireless
Yes, you can get a directional antenna that will improve your signal to that WiFi node. If your smartphone or laptop has a WiFi antenna connector you need only find the right cable or adapter to connect
