The wireless broadband revolution: How it revolutionized the way we surf the Internet?
Wireless broadband is a telecommunications technology that provides users with high-speed wireless Internet access and computer network access, whether in fixed or mobile scenarios. With the advancement of technology, the popularity of wireless broadband has greatly changed the way we access the Internet, providing convenience and opportunities for users around the world.
"Originally the word 'broadband' had a technical meaning, but over time it became a marketing term covering a variety of relatively high-speed computer network or Internet access technologies."

Broadband Evolution and Standards
The definition of "wideband" was set as early as the 802.16-2004 standard, indicating an instantaneous bandwidth exceeding 1 MHz and supporting a data rate of approximately 1.5 Mbit/s. Recently, the Federal Communications Commission (FCC) redefined "broadband" to require download speeds of at least 25 Mbit/s and upload speeds of at least 3 Mbit/s.
Technology and Speed
Wireless broadband networks primarily provide connections to multiple users and can achieve data transfer rates of more than 1 Gbit/s. Many fixed wireless networks are half-duplex (HDX), but some licensed systems are capable of simultaneous full-duplex (FDX) communications, greatly improving communication efficiency.
"Fixed wireless broadband services are becoming increasingly popular in many rural areas that lack cable or DSL service."
The development of the United States
The wireless broadband market has changed significantly in the United States since the launch of the licensing and registration process for the 3650-3700 MHz band in 2007 and the adoption of TV white space rules in 2010. The first wireless Internet service providers (WISPs) were concentrated in rural areas, which lacked Internet coverage.
Residential Wireless Internet
Traditional fixed wireless broadband service providers typically provide customers with equipment and install a small antenna or dish on the user's roof. This enables users within the service area to obtain a relatively stable Internet connection.
Business Wireless Internet
More and more businesses are looking for wireless alternatives, especially in areas where affordable Ethernet connectivity is difficult to obtain. These wireless solutions not only provide excellent services, but also meet the needs of enterprises for the continuous integration of multiple communication services.
The need for spectrum
As wireless broadband usage increases, demand for spectrum is also rising. This prompted studies to be launched since 2009, but despite the existence of unused spectrum, broadcasters were strongly opposed to giving up spectrum.
Mobile Wireless Broadband
In the United States, mobile wireless broadband technology continues to advance, with providers such as Verizon and AT&T providing convenient mobile network access. Consumers can connect to the Internet via PC cards, USB devices or mobile broadband modems and enjoy the convenience of mobility.
Authorized and Unauthorized Connections
Wireless connections can be divided into authorized and unauthorized. In the United States, licensed connections rely on private spectrum authorized by the FCC, while unlicensed connections typically use public spectrum, such as a combination of multiple frequency bands such as CBRS.
"Many wireless ISPs use unlicensed spectrum, which allows them to provide service in the public domain without having to pay high spectrum licensing fees."
The rapid development and widespread application of wireless broadband technology are changing our lifestyles and business models. Will it be able to maintain its position in the future and meet the growing bandwidth demands?
