Bluetooth is a wireless networking protocol that operates on the 2.4GHz frequency. It is used to connect devices such as headphones, speakers, and other peripherals to a computer or mobile device. Bluetooth has a shorter range than other wireless networking protocols and is not typically used for connecting to a wireless network for internet access.
802.11 a - b - g - n - ac (WiFi 5) - ax (WiFi 6)
These are a series of protocols for wireless networking, with each protocol providing different speeds and frequency ranges. The most commonly used protocols are:
802.11a: Operates in the 5GHz frequency range and supports data transfer speeds of up to 54Mbps.
802.11b: Operates in the 2.4GHz frequency range and supports data transfer speeds of up to 11Mbps.
802.11g: Operates in the 2.4GHz frequency range and supports data transfer speeds of up to 54Mbps.
802.11n: Operates in both the 2.4GHz and 5GHz frequency ranges and supports data transfer speeds of up to 600Mbps.
802.11ac (WiFi 5): Operates in the 5GHz frequency range and supports data transfer speeds of up to 6.9Gbps.
802.11ax (WiFi 6): Operates in both the 2.4GHz and 5GHz frequency ranges and supports data transfer speeds of up to 9.6Gbps.
Long-range fixed wireless
This technology is used to provide internet access to remote areas, using either licensed or unlicensed frequencies. The range of long-range fixed wireless varies depending on factors such as power and regulatory requirements for wireless power.
Long-range fixed wireless refers to wireless networks that cover longer distances and are used for providing internet access in remote areas or for connecting distant buildings. Two types of long-range fixed wireless networks are licensed and unlicensed wireless networks.
Licensed wireless networks operate on specific frequency bands that are licensed by the government, and users must have a license to use them. These networks provide a high level of reliability, speed, and security, but they are also expensive and subject to strict regulatory requirements.
Unlicensed wireless networks, on the other hand, operate on frequency bands that are available for public use without the need for a license. These networks are cheaper to set up and operate, but they may suffer from interference and have lower reliability and security.
Power is an important consideration for long-range fixed wireless networks, as the amount of power required for transmitting data over long distances is higher than for shorter distances. High-power wireless systems require regulatory approval to ensure that they do not interfere with other licensed services operating on the same frequency band.
Regulatory requirements for wireless power include limits on the maximum amount of power that can be transmitted, as well as restrictions on the frequency bands that can be used for transmission. Regulatory bodies such as the Federal Communications Commission (FCC) in the United States set these requirements to ensure that wireless networks do not interfere with other wireless services and to protect public health and safety.
NFC: Stands for Near Field Communication, and is a short-range wireless communication protocol that allows devices to transfer data over a distance of a few centimeters.
RFID: Stands for Radio-Frequency Identification, and is a wireless communication protocol that uses electromagnetic fields to identify and track tags attached to objects. RFID can operate over short or long distances, depending on the frequency and power used.
