Wireless communication technology is one of the most accessed technology now and everywhere. The term wireless defines to communication or transmission of data without requiring cables, wires or any electrical conductors. The deep study of wireless communication was held to find ways to increase the speed of data transmission so less time to transmit data or avoid data loss. The loss in transmitted data usually occurs due to multi-path fading especially in an indoor environment. This research is carried out by conducting a measurement campaign at 2.4 GHz in an indoor environment at administration building hallway of Kolej GENIUS Insan to evaluate the path loss. 2.4GHz radio signal is used to evaluate the path loss. The signal is generated by the Wi-Fi router in Kolej GENIUS Insan. The Received Signal Strength (RSS) is measured, hence the loss or data delay in data transmitted is calculated and analysed. This study found that the element of building furniture and edge result to better signal reception.

Electricity can be generated from many ways such as from kinetic energy of flowing water. Energy also can be split into two categories such as renewable energy and non-renewable energy. Photosynthetic organism is the plant that can make own food by itself. Basically, the plant will absorb sunlight and convert it into food and also energy chemically. Thus, this research indicates that photosynthetic plants can produce electricity by itself. The aim of this research is to measure the portion of electricity that can be manufactured by photosynthetic algae plantation. First and foremost, the expected result of this research is the electricity that will be produced will be greater when it was measured at noon because there is ample source of light energy from sun for the plants to undergo photosynthesis. In addition, lower electricity will be recorded when it was measured at night because of the low rate of photosynthesis. From this project, we also can prove that the certain plant in this world can be used in electricity production. Furthermore, we want to develop the usage of photosynthesis of algae plantation in order to produce electrical energy in our country.
