The line of sight (LOS) microwave communication system, especially those operating at frequencies above 10 GHz, is very susceptible to rain attenuation, particularly in tropical countries such as Indonesia. Therefore, it is essential to calculate rain attenuation estimation values as a basis for consideration in designing a line of sight microwave communication system to get stable communication. In this study, telemetering was designed to measure the rainfall intensity from a rain gauge device through a 433 MHz wireless transceiver. Measurement of rainfall intensity values via an Arduino-controlled rain gauge was transmitted directly to the monitoring room, which then processed to be displayed in graphical form in real time and can also be stored as data loggers. The rainfall telemetering device users can measure rainfall remotely and without having to wait for the rain like the rainfall manual measurement.

This thesis explores a technique for the fusion of streamed audio and video services for real-time applications. It discusses certain novel techniques used to overcome the problems with video and audio synchronization over the Internet of a tele-bot. We have developed a demonstration called the WAX, at the Network-Centric Applied Research Team (N-CART) laboratory located within the School of Computer Science at Ryerson University. WAX is equipped with an onboard camera and a microphone, as well as a 2.4 GHz wireless transceiver for transmitting video and audio feeds, and at the same time receiving commands from the WAX robot server. By launching a web browser and loading the Java client applets, a user can see as well as hear what is around WAX in near real-time, while being able to move the robot around its environment.

In nowadays we need to stay connected. In most of the college’s, announcements are seen under the major problem. A universal announcement by speakers is usually deployed in most of the institutes, but there are cases when the announcement must be for specific classroom or for a specific person. There in case, such a universal system won't be helpful. Talking of colleges, the scenario in the classroom currently involves communicating facilities. The communication is generally using a student address system accessible from the control room only. This system removes a delay in case of emergency or even when an urgent communication is to be made. The proposed system aims to connect the communication between HODS or an authorized person of the department to the students or workstation, thereby ensuring good communication. We can achieve this using NRF24L01 Antenna Wireless Transceiver, Arduino NANA, Sound detection sensor module and speakers.


While working to deliver an app that send commands to the vehicle, I noticed it will not function properly when the phone battery dies. I thought to have the other regular key as alternative solution but the customers did not like to carry the bulky keys. I did some research and came up with a credit card form factor with the same functionalities of a regular key. I added value of Bluetooth chip that connects to the app. I also realized some customers own multiple vehicles and I added a memory chip to save the key learning of up to four vehicles. From the app we can decide what the active profile is. A system includes a mobile device and a fob, each having a short-range wireless transceiver. The mobile device is programmed to transmit a message to the fob indicating a fob action using the mobile device transceiver. The fob is programmed to, using the fob transceiver, receive the message and transmit a second message to a vehicle requesting the vehicle to perform the fob action. In one or more illustrative examples, a system includes a mobile device and a fob, each having a short-range wireless transceiver. The mobile device is programmed to transmit a message to the fob indicating a fob action using the mobile device transceiver, and the fob is programmed to, using the fob transceiver, receive the message and transmit a second message to a vehicle requesting the vehicle to perform the fob action. In one or more illustrative examples, a method includes transitioning a fob into valet mode by sending a wireless short-range message to the fob responsive to receiving input to a mobile device to set the fob into valet mode; and transitioning the fob from valet mode into full access mode by sending a second wireless short-range message to the fob responsive to receiving second input to the mobile device to remove the fob from valet mode. In one or more illustrative examples, a system includes a mobile device and a fob, each having a short-range wireless transceiver. The mobile device is programmed to, responsive to user input, transmit a message using the mobile device transceiver to the fob to transition the fob from being configured to control a first vehicle profile to being configured to control a second vehicle profile, and the fob is programmed to, using the fob transceiver, receive the message and control the second vehicle.
