2.3 Fixed Wireless Flashcards
What is the main characteristic of a fixed wireless network?
It provides wireless internet access to stationary locations rather than mobile users.
What type of antennas does 802.11 fixed wireless (Wi-Fi) use for point-to-point connections?
Directional antennas.
What frequency bands does 802.11 fixed wireless (Wi-Fi) operate in?
Unlicensed 2.4 GHz and 5 GHz bands.
What are fixed cellular networks used for?
Providing stationary broadband internet access using larger antennas for higher speeds.
What is an advantage of 5G fixed wireless over traditional broadband?
It offers high-speed internet without requiring wired infrastructure.
What is the primary limitation of microwave links?
They require a clear line-of-sight (LOS) to function properly.
What is the maximum range of microwave links?
Up to 40 miles.
What are the two types of satellite internet connections?
Low Earth Orbit (LEO) and Geosynchronous Orbit (GEO).
What is a major advantage of LEO satellites over GEO satellites?
Lower latency due to their closer proximity to Earth.
What is the main drawback of satellite internet connections?
High latency, especially with GEO satellites.
Why does fixed wireless cellular require FCC regulation?
It operates on licensed frequencies that require government approval.
What are the differences between licensed and unlicensed spectrum?
Licensed spectrum requires FCC approval (cellular, microwave, satellite), while unlicensed spectrum (Wi-Fi) is open for public use.
What is the primary advantage of microwave over Wi-Fi for fixed wireless connections?
Microwave provides longer range and higher reliability.
What are some examples of fixed wireless broadband technologies?
Wi-Fi (802.11), Fixed Cellular (4G/5G), Microwave, and Satellite.
What type of wireless technology is used for short-range building-to-building links?
802.11 Wi-Fi with directional antennas.
