It's transported with wireless protocols (802.11 standards) through the air on different frequencies. Most common frequency used for wireless data is 2.4 GHz. Many newer wireless technologies are moving to different frequencies due to congestion on 2.4
The common wireless frequency is 2.4 Ghz. Some wireless networks may use the 5 Ghz frequency range.
a wireless most often as it was easier.
Whether a wireless computer keyboard uses microwave frequencies for communication with the computer depends on the technology used by the keyboard, and on the definition of microwave frequencies. Wikipedia defines microwave frequencies to be in the 1...30GHz range. Many wireless keyboards operate in the 2.4GHz band, which would make them microwave transmitters (and receivers). Other keyboards use different frequencies, below 1GHz. Those would not be microwave devices, according to this definition. The 802.15.4 standard, for example, lists a 868.0-868.6MHz band (Europe), 902..928MHz (US) and the 2.4GHz (2400...2483.5 MHz) band (worldwide, but subject to regional restrictions).

Most baby monitors won't interfere with wireless internet as they use different frequncies. Monitors usually cause more problems for cordless phones. But Summer makes a great video mointor that does not interfere with wireless internet connections at all. It uses three different selectable frequencies so the best one can be used that works the best in your location.
When frequencies have been used for one purpose, perhaps for decades, it is often difficult to reallocate these frequencies for a different use. The need for reallocation - often known as re-farming - can arise in several ways.
One frequency that is not commonly used for wireless communications is the extremely low frequency (ELF) range, typically below 3 Hz. This range is unsuitable for conventional wireless communication due to its long wavelength, which requires impractically large antennas and is primarily used for specialized applications like submarine communication. In contrast, frequencies in the megahertz (MHz) and gigahertz (GHz) ranges are widely used for various wireless communication technologies.
Frequencies above the human hearing range are called ultrasonic frequencies. These frequencies typically range from 20 kHz to several gigahertz and are often used in various applications such as ultrasonic cleaning and medical imaging.
Frequencies around 2.4 GHz and 5 GHz are commonly used for Wi-Fi, Bluetooth, and other wireless communication technologies in English-speaking countries. AM and FM radio frequencies are also widely available for listening to English language broadcasts.
It means that the wireless network adapter supports both 802.11b (2.4GHz) and 802.11a (5GHz) frequencies. 802.11b was the first mainstream wireless networking solution. 802.11a was mostly used in corporate environments where throughput was more important than range.
