Wi-Fi Alliance® advocates for unlicensed spectrum, and for ensuring that the benefits Wi-Fi delivers can be maintained.
What are the unlicensed frequency bands?
The US Federal Communications Commission (FCC) has three primary frequency bands designated for unlicensed operation. Unlicensed means the operator of the radios does not need to file directly with the FCC to use the radio. The three frequency bands used for this in the U.S. are the 900 MHz, 2.4 GHz and 5.8 GHz.
Is Wi-Fi unlicensed spectrum?
Answer: Wi-Fi is a particular service that uses unlicensed spectrum, but there are others as well. As the FCC puts it: … Wi-Fi uses unlicensed spectrum, open to use by any device that has been certified by the FCC as conforming to its Part 15 rules on transmitted electromagnetic energy.
What is the unlicensed spectrum typically used for?
Unlicensed spectrum was first established by the FCC in 1985, and allows the public to freely use services without a license, such as Wi-Fi networks, baby monitors, and cordless telephones.
What are the unlicensed bands allowed by the FCC?
Unlicensed wireless microphone use is permitted on the 902-928 MHz band, the 1920-1930 MHz, and on portions of the 2.4 GHz and 5 GHz bands under specified power levels and rules for operation for each of those bands.
What are the different types of frequency bands?
Frequency Bands and Applications
|Frequency Band Name||Acronym||Frequency Range|
|Medium Frequency||MF||300 to 3000 kHz|
|High Frequency||HF||3 to 30 MHz|
|Very High Frequency||VHF||30 to 300 MHz|
|Ultra High Frequency||UHF||300 to 3000 MHz|
Is 900 MHz unlicensed?
For wide-area communications, the primary unlicensed bands used are 900 MHz (868 in Europe, 915 in the US) and 2.4 GHz. These unlicensed bands are free to use, but are subject to regulations and the potential interference of competing wireless signals.
Is unlicensed spectrum free?
Users are not dependent on any operator to use an unlicensed spectrum. It is free for all. What is the disadvantage of an unlicensed spectrum? Managing interference between adjacent users is more difficult in unlicensed than licensed spectrum.
What is the difference between licensed and unlicensed bands?
“Regulations exist around these bands, so using unlicensed radio bands is not a free-for-all. The big difference between licensed and unlicensed bands is that the licensed bands are allowed to be used only by the company that licensed them, whereas the unlicensed bands are used by anyone who wants to use them.”
What is the difference between licensed and unlicensed spectrum?
Using a licensed spectrum has two significant benefits: greater reliability and better performance. … Unlicensed spectrum users are competing with other users for priority. And as an unlicensed user, you have no protection from interference on the part of other parties.
What is meant by unlicensed spectrum?
For example, when the FCC auctioned parts of the 700mhz frequency block in 2008, Verizon and AT&T spent over $16 billion in acquiring these licenses. Unlicensed Spectrum is actually very similar. Unlicensed Spectrum is a designation of frequencies that do not have exclusive access.
What is unlicensed radio spectrum?
Broadly speaking, radio spectrum is divided into two types: licensed and unlicensed. … These are the ones licensed by the government to cellular companies, as one example. Unlicensed spectrum, also called license-free spectrum, is publicly owned, and people do not have to apply and pay for a license to use them.
Who uses 700 MHz band?
The 700 MHz frequency band consists of radio spectrum in the range 694-790 MHz. It is part of the wider ultra-high frequency (UHF) band, currently used throughout Europe for terrestrial broadcasting.
Is 6GHz unlicensed?
The Federal Communications Commission voted today to open up a plot of spectrum in the 6GHz band for unlicensed use — the same regulatory go-ahead that lets your router broadcast over the 2.4GHz and 5GHz bands. … This is the biggest spectrum addition since the FCC cleared the way for Wi-Fi in 1989, so it’s a huge deal.
