Question 1

How Many Devices Can Wi-Fi Handle?

Accepted Answer

The total number of devices a WiFi network can handle will be defined by the subnet. The most common subnet used in homes is called a Class C (also known as /24) subnet, which gives you 254 unique IP addresses your devices can use.

Question 2

What Frequency Does Wi-Fi Operate On?

Accepted Answer

The wireless signals between our devices and the Wi-Fi router work on two frequencies, which are 2.4 GHz and 5 GHz. These then are divided into channels of different widths. Finding a channel that has little/no interference from other wireless networks in your neighbourhood can improve your connection and give a better throughput.

Question 3

What Is The Range Of Wifi?

Accepted Answer

The range of WiFi is a tricky question, as it will vary depending on many factors. The best answer would be that if you intend to get the most out of your Wifi, you should try to position your router in the centre of where you plan on using it. The typical range of 2.4 GHz wifi is about 30/35m. So location and placement are important to get the flexibility you want with your setup. The typical range of 5 GHz WiFi is about 10/15m, but this varies depending on a lot of factors like the closeness of walls, obstructions, and other electronic equipment.

Question 4

What Is The Topology Of A Wi-Fi Network?

Accepted Answer

The Star topology is the most common network topology for WiFi. However, Mesh networks are becoming more popular in households due to their easy setup and improved performance.

Question 5

What Is The Data Throughput On A Wi-Fi Network?

Accepted Answer

There are lots of variables to consider, and it's difficult to predict a "real world" figure. The "advertised maximum speed" for the 802.11ac/ax standards are as follows, but your real-world results will definitely vary.

WiFi 6 (802.11ac) - 9.6 Gbps
WiFi 5 (802.11ac) - 3.5 Gbps

It is important to note that factors such as your distance from the access point, interference from other networks and the number of clients on your network can impact performance.

Question 6

What Level Of Encryption Does Wifi Have?

Accepted Answer

WiFi encryption is the process of securing your WiFi network from outside intruders. It's an important step in making sure your personal data isn't compromised by hackers. There are three common types of encryption these days: WEP, WPA, WPA2 and the newer WPA3.

WEP & WPA are the older, less secure encryption methods. WPA2-PSK is considered the best type of internet security that is widely available at the time because it uses the strongest encryption currently available. WPA3 is the newest encryption method on the market with the strongest encryption available, but not many devices support it yet.

Question 7

How Many Devices Can Z-Wave Handle?

Accepted Answer

When it comes to the Z-Wave network, the total number of devices it can handle is 232.

Question 8

What Frequency Does Z-Wave Operate On?

Accepted Answer

In Europe and the United Kingdom, Z-Wave operates on the 868.42 MHz frequency. Within Canada and the United States of America Z-Wave operates on the 908.42 MHz frequency.

Question 9

What Is The Range Of Z-Wave?

Accepted Answer

In general, Z-Wave devices have a maximum range of 100 m when used unobstructed in an outdoor setting. When Z-Wave is used indoors the signal will be reduced to about 24m, this will vary with each installation. Through the use of special signal repeaters, Z-Wave can overcome obstacles while still keeping communication between devices.

Question 10

What Is The Topology Of A Z-Wave Network?

Accepted Answer

The Z-Wave protocol operates on a Mesh topology, so all devices can send data between them. A common misconception is that Z-Wave operates on a wireless radio wave, like Wi-Fi or Bluetooth. In reality, it’s a mesh network—a network of devices that work together to transmit information so one device can reach another device farther away from the original sender without using extra power and bandwidth.

Question 11

What Is The Data Throughput On A Wi-Fi Network?

Accepted Answer

A Z-Wave network can transmit data at three different speeds. Those speeds are 9.6 kbps, 40 kbps or 100 kbps.

Question 12

What Level Of Encryption Does Z-Wave Have?

Accepted Answer

The Z-Wave protocol can be encrypted with AES-128 encryption. This means that anyone who wants to communicate with a wireless Z-Wave product will have to know the encryption key in order to understand and decrypt the signal.

Question 13

Which protocol is well known for its use in the home security and home automation industry, uses a mesh topology, makes devices act as repeaters, and has a low data transfer rate?

Accepted Answer

Z-Wave's low data transfer rate makes it useful both for home automation and for home security. The mesh topology of Z-wave allows other Z-wave devices to act as signal repeaters, making the network stronger.

Question 14

How Many Devices Can ZigBee Handle?

Accepted Answer

The ZigBee protocol, which is used for wireless communications among devices and wireless mesh networks, can be expanded to allow up to 65,000 devices per network. The ZigBee protocol and wireless mesh networks can be used to solve several challenges associated with the Internet of Things.

Question 15

What Frequency Does ZigBee Operate On?

Accepted Answer

ZigBee operates at the 2.4 GHz to 2.485 GHz frequency, and is a low-power, low-cost, wireless protocol that can be used for personal area networks and as a home automation protocol.

Question 16

What Is The Range Of ZigBee?

Accepted Answer

A typical ZigBee range is up to 100 meters (330 ft), which can be extended with mesh repeaters nodes. With a mesh network, the maximum range is theoretically unlimited, but in practice, it may be limited by physical obstructions or by insufficient signal strength.

Question 17

What Is The Topology Of A ZigBee Network?

Accepted Answer

A ZigBee network is a Mesh topology network made up of nodes or devices that have one or more radios. They use ZigBee as the communication protocol to talk with each other over meshed radio waves. The mesh network is achieved when all ZigBee radios are capable of being an 802.15.4 coordinator node, which means that any node can create another network or extend the existing one if they come across a link failure.

Question 18

What Is The Data Throughput On A ZigBee Network?

Accepted Answer

The data throughput of a ZigBee network is 20 kbps, 40 kbps, 100 kbps and 250 kbps.

Question 19

What Level Of Encryption Does ZigBee Have?

Accepted Answer

The ZigBee protocol can be encrypted with AES-128 encryption. Only those who have the encryption key will be able to read the data that is being sent to/from ZigBee devices.

Question 20

How Many Devices Can MQTT Handle?

Accepted Answer

The MQTT protocol will typically use the TCP/IP framework, so the device limit may be inherited from that. Tests have shown that the MQTT broker Mosquitto could support 60,000 publishers.

Question 21

What Frequency Does MQTT Operate On?

Accepted Answer

MQTT protocols are typically used for 2.4Ghz/5Ghz WiFi networks, however, as discussed above, they can be used with any network that supports bidirectional, lossless, orderly communications.

Question 22

How Many Devices Can Thread Handle?

Accepted Answer

The Thread protocol can handle up to 16,384 clients with 32 routers in the network. These characteristics make it set to become one of the most widely used protocols in home automation.

Question 23

What Frequency Does Thread Operate On?

Accepted Answer

The Thread protocol operates on the 2.4GHz frequency band.

Question 24

What Is The Range Of Thread?

Accepted Answer

Thread is a home automation protocol that uses low-power wireless mesh networking to provide reliable and secure communication. The range of the Thread devices will typically be determined by the number of Thread devices you have. As this is a mesh network, the more devices you have, the better the network gets. It’s like having multiple routers in different parts of your house that are all connected.

Question 25

What Is The Topology Of A Thread Network?

Accepted Answer

In the Thread protocol, there is a mesh topology, which ensures that messages can be relayed from other devices until they reach their intended targets if there is no direct link.

Question 26

What Is The Data Throughput On A Thread Network?

Accepted Answer

The data throughput on a network using the Thread protocol is 250 kbps.

Question 27

What Level Of Encryption Does Thread Have?

Accepted Answer

The Thread protocol includes security features like AES-128 encryption.

The Thread protocol is a new standard for low energy wireless mesh networks that provides two-way communication with no infrastructure to manage. The Thread protocol is designed to be an open, scalable, and secure mesh network platform for the Internet of Things (IoT).
