Situation during COVID19 pandemic, requires all schools to conduct online learning. This condition is done to prevent the
spread of pandemic. The problem is that the infrastructure is not fully supported. Learning in marginal areas is still constrained
by the difficulty of the signal or internet connection. This research was conducted to obtain an infrastructure design that can
be used in areas with minimal internet connection, or even no internet network connection. Using R&D, the research begins
by designing a network device on the school side – Acces Point, also a tool to expand coverage - repeater. Furthermore, design
and testing of signal amplifier antennas that can be used on the client side is carried out. For the client side, several types of
amplifier antennas are made that can be used to receive Wifi frequencies. There are three types of antennas that are made and
tested, namely Yagi, Yagi Cross, and cantennas. Both are Unidirectional antenna. Connection quality is measured with a Wifi
analyzer device to determine network quality. As for mobile phones, it is measured using the Wifi Master Key. The result
obtained is a WELAN infrastructure design which is equipped with unidirectional antenna design with a total range of 8 Km.
