Using frequency hopping and sweep modes, Zinn's method is primarily applied in low data rate wireless applications such as utility metering, machine and equipment monitoring and metering, and remote control. In 2006 Zinn received U.S. patent 6,996,399 for his "Wireless device and method using frequency hopping and sweep modes."
Wireless standard IEEE 802.11 uses either FHSS or DSSS in its radio interface. Techniques known since the 1940s and used in military communication systems since the 1950s "spread" a radio signal over a wide frequency range several magnitudes higher than minimum requirement.
LE-ACL employs a spread spectrum scheme known as adaptive frequency hopping. At the start of each connection event, frequency hopping occurs, with one of the 37 general purpose Bluetooth LE radio channels being selected from the set of available channels using a channel selection algorithm. Each device in the connection will then switch to the ...
Time Slotted Channel Hopping or Time Synchronized Channel Hopping (TSCH) is a channel access method for shared-medium networks. TSCH is used by Low-Power devices to communicate using a wireless link. It is designed for low-power and lossy networks (LLNs) and aims at providing a reliable Media access control layer.
Weightless-W uses time-division duplex operation with frequency hopping and variable spreading factors to increase range and accommodate low-power devices in frequency bands, or channels, within the terrestrial television broadcast band. Channels used by a nearby television transmitter are identified and left unaffected, while channels not ...

Chirp spread spectrum was originally designed to compete with ultra-wideband for precision ranging and low-rate wireless networks in the 2.45 GHz band. However, since the release of IEEE 802.15.4a (also known as IEEE 802.15.4a-2007), it is no longer actively being considered by the IEEE for standardization in the area of precision ranging.
American wireless carrier Nextel Communications field tested wireless broadband network technologies including Flash-OFDM in 2005. [53] Sprint purchased the carrier in 2006 and decided to deploy the mobile version of WiMAX, which is based on Scalable Orthogonal Frequency-Division Multiple Access (SOFDMA) technology. [54]
