QUESTION 18 Radio frequency (RF) signals travel from a transmitter to a receiver. The transmitter can contact the receiver at anytime, as long as both devices are (choose two) Tuned to the same frequency (or channel) Adjusted to the same speed Use the same modulation Use the same data. Both devices are on QUESTION 19 Which wireless networks connection modes used to connect clients to the network using an AP Tethering mode Distributed mode Ad-hoc mode OOOO Infrastructure mode
Protection System
A system that protects electrical systems from faults by isolating the problematic part from the remainder of the system, preventing power from being cut from healthy elements, improving system dependability and efficiency is the protection system. Protection devices are the equipment that are utilized to implement the protection system.
Predictive Maintenance System
Predictive maintenance technologies are designed to assist in determining the state of in-service equipment so that maintenance can be scheduled. Predictive maintenance is the application of information; proactive maintenance approaches examine the condition of equipment and anticipate when it should maintain. The purpose of predictive maintenance is to forecast when equipment will fail (depending on a variety of parameters), then prevent the failure through routine and corrective maintenance.Condition monitoring is the continual monitoring of machines during process conditions to maintain optimal machine use, which is necessary for predictive maintenance. There are three types of condition monitoring: online, periodic, and remote. Finally, remote condition monitoring allows the equipment observed from a small place and data supplied for analysis.
Preventive Maintenance System
To maintain the equipment and materials on a regular basis in order to maintain those running conditions and reduce unnecessary shutdowns due to unexpected equipment failure is called Preventive Maintenance (PM).
Please, I need the final solution as soon as possible, I do not need any explanation or explanation
SOLUTION
QUESTION-18
ANSWER
Tuned to the same frequency(channel)
Both devices are on
EXPLANATION
Transmitter and receiver must be tuned to the same frequency if both tuned to different frequency then they can't able to communicate with each other because at this situation both will receive different signal.
