What is the maximum range for 60 GHz system communication?
Telecommunications. In the United States, the band 36.0–40.0 GHz is used for licensed high-speed microwave data links, and the 60 GHz band can be used for unlicensed short range (1.7 km) data links with data throughputs up to 2.5 Gbit/s.
What is the range of 60 GHz WIFI?
60GHz Wireless: The IEEE 802.11ay standard 802.11ay is a type of WLAN in the IEEE 802.11 set of WLANs. It will have a frequency of 60 GHz, a transmission rate of up to 40 Gbps and an extended transmission distance of 300–500 meters.
What does 60 GHz do to oxygen?
At 60 GHz, the oxygen molecule becomes highly absorbent of electromagnetic energy, which weakens the 60 GHz signals over distance, keeping them from overshooting their intended target.
What is 60 GHz used for?
Point-to-point wireless systems operating at 60 GHz have been used for many years by the intelligence community for high security communications and by the military for satellite-to- satellite communications.
Does 60 gigahertz absorb oxygen?
At the millimeter wave frequency of 60GHz, the absorption is very high, with 98 percent of the transmitted energy absorbed by atmospheric oxygen. While oxygen absorption at 60GHz severely limits range, it also eliminates interference between same frequency terminals.
Is 60 GHz license free?
Unlike the lightly licensed 70/80 GHz E-Band, the 60 GHz band is unlicensed, and therefore, is accessible to a wider range of providers.” Further, the 60 GHz band has chipsets and technology currently available on the commercial market.
What is the main drawback of using the 60 GHz frequency for wifi?
There are some major disadvantages to the 60GHz band. Probably the most important aspect of the 60GHz band for low-power wireless communications is the path loss. Path loss will be discussed in more depth below, but it suffices to say that an omnidirectional antenna at 60GHz suffers from severe path loss.
Can 60GHz absorb oxygen?
Why is the 60 GHz band not good for long range communications?
At 60 GHz, Oxygen molecules in the atmosphere interact with the RF signals to cause significant attenuation. Due to this attenuation the 60 GHz band is not a good frequency to use for long-range radar or communication applications. At 60 GHz O2 can cause an attenuation of up to 10 dB/km.
Do you need a license for 60 GHz?
The 60 GHz band is an excellent choice for high-speed Internet, data, and voice communications offering many key benefits and advantages: Unlicensed operation – no need to spend significant time and money to obtain a license from FCC or other regional regulator (note: not in all countries)
Is 60 gigahertz harmful to humans?
In addition to the very low power levels discussed above, 60 GHz systems do not penetrate the human body. As a result, exposure to 60 GHz is very similar to the exposure to sunlight ” but at 1/10,000 of the energy. Lower-frequency emissions penetrate and may even pass completely through the human body.
What are the advantages and disadvantages of 60 GHz band?
Benefits or advantages of 60GHz frequency ➨Millimeter wave band allows use of higher EIRP (Effective Isotropic Radiated Power), which is about +40 dBm in USA and CANADA. ➨As it uses low power for transmission there is less likelihood of any interference. Hence it increases frequency reuse density.
