The purpose of this paper is to evaluate WiFi (IEEE 802.11 b/g/n) performance of ESP32
modules in outdoor scenarios using an offthe-shelf access point (AP). This was done by …

The purpose of this paper is to evaluate WiFi performance of the ESP32 module in outdoor
scenarios. This was done by measuring the received signal strength indicator (RSSI) at …

A large amount of sensing data generated by multiple sensors is collected through the cloud
platform, while the amount of data over the network is increasing rapidly. IoT applications …

To assist soldiers in training agility and accuracy, a technology is needed for movement and
targets, many factors need to be considered, such as field conditions, target movement and …
