Answer:
Z-Wave
Explanation:
1. Wi-fi because it is always encrypted. This is good because Bandwidth is high—up to 2 MHz, however it only works if the signal is strong and device is close to the access point. Its average range is between 30 to 100 meters. This drawback only makes this technology not a good option.
2. ZigBee because it is always encrypted, ZigBee has lot of edge like largest number of device to connect 6500 theoretically, low power usage, faster and others compared to other which would have made it a better option to recommend to my company but it has interoperability issues
3. Z-Wave because it is the fastest wireless standard apart from this Z-wave has better interoperability, reliability, low frequent which does not interfere with Wi-Fi network, maintain backwards compatibility across all versions which is good for maintenance, Z Wave network to have greater ranges and ability to “bend” around obstacles.
4. Bluetooth because it is easiest to configure Low Energy (LE) is better at conserving power, it has a much longer range compared to others —up to 300 feet, under ideal circumstances—its low transmission rate will keep it from being used for data-heavy applications such as video.
In view of security and distance and compared with other IoT protocol i would recommended Z-Wave
The examination phase
Further Explanation:
Hardware troubleshooting in computers requires a systematic and logical approach. Taking a logical approach helps you identify the root cause much easily. Ask yourself those questions first before getting to the bottom of anything. You will find it helpful to reproduce the problem and develop a hypothesis of the problem if you ask yourself those 20 questions.
Next comes the examination phase. Having gathered everything, I will now attempt a fix based on what I think I found. In my case, I suspect that there a component in my computer that is fried. A few ways to tell if my motherboard or components attached to the motherboard are fried is to remove the side panel first and examine the circuitry before removing any unnecessary hardware devices. Obvious sings will be smell of smoke. Examine the capacitors as well. Burnt capacitors have rounded tops. This is a clear indication that they are blown.
I will now remove every single component one by one from the motherboard and test my hardware on a low-level.
