Fixed wireless network speeds exceeding 1 Gbit/s! How on earth is this possible?
Advances in fixed wireless network technology are rapidly changing the way we access the Internet. As demand increases, wireless broadband technology not only provides high-speed Internet access, but also maintains high-performance connections over wider areas. Today, the speed of fixed wireless networks has exceeded 1 Gbit/s. What technology is used to achieve this?
Wireless broadband is broadly defined as technology that provides high-speed wireless Internet access or computer network access. From a technical perspective, the concept of "broadband" initially refers to having real-time bandwidth higher than 1MHz and supporting high-speed data transmission. According to the redefinition of the Federal Communications Commission (FCC), the minimum download speed of broadband must reach 25 Mbit/s, and the upload speed must be at least 3 Mbit/s.
Wireless networks can achieve data transfer rates in excess of 1 Gbit/s.
The evolution of wireless technology
Wireless broadband networks mainly provide fixed and mobile wireless services. This type of network generally uses terrestrial wireless links, which can be point-to-point or point-to-multipoint, which greatly improves the access speed and stability of the Internet. The advancement of wireless access technology lies not only in fast data transmission, but also in its ability to maintain good performance in changing environments.
Advantages of half-duplex and full-duplex
In many fixed wireless networks, transmission mainly uses half-duplex (HDX) technology, although some licensed and unlicensed systems can implement full-duplex (FDX) mode simultaneously, enabling two-way communication. This technology enables the performance of fixed wireless networks without interference when transmitting data, greatly improving the reliability of the connection.
The key to signal transmission and reception
In outdoor fixed wireless broadband networks, priority TDMA (Time Division Multiple Access) protocols are often used, which requires communication scheduling to be divided into time segments to avoid common problems under the 802.11 Wi-Fi protocol. In this way, Wireless Internet Service Providers (WISPs) can provide connectivity at a range of up to 50 kilometers.
Many wireless Internet service providers offer download speeds in excess of 100 Mbit/s, demonstrating the potential of wireless technology.
Application of technology in the United States
In 2007, the US Federal Communications Commission announced the opening of the 3650 MHz frequency band to support terrestrial wireless broadband operations. With the introduction of the Television White Space Rules (TVWS) in 2010, certain frequencies that do not require line-of-sight have been further applied. These changes have promoted the popularity of wireless services, allowing more residents and business users to access reliable Internet.
Changes in Home and Business Networks
Many homes and businesses are beginning to use fixed wireless broadband services, especially in remote areas where traditional wired networks cannot reach them. Fixed wireless services typically involve providers providing the necessary equipment and placing small antennas or satellite dishes on rooftops to improve signal reception. Such service plans allow flexible use of sales methods and lower the threshold for users.
Market demand and future development
As demand surges, the demand for wireless spectrum is increasing. While some free spectrum is available for wireless broadband, reallocation of spectrum remains a challenge due to opposition from the broadcast community. In the United States, many mobile wireless broadband services rely on mobile communication towers to provide stable network connections, allowing consumers to connect to the Internet anytime and anywhere.
As technology evolves, users may be faced with more choices, allowing them to use wireless broadband services with greater convenience.
How these wireless technologies will further promote the wave of digitalization in the future and meet the growing needs will become the focus of the industry. So, in the future digital realm, will we be able to experience faster wireless Internet speeds and more stable connections?
