Father of Wi-Fi | Vic Hayes

Victor "Vic" Hayes (born July 31, 1941 Surabaya, Dutch East Indies) is a former Senior Research Fellow at the Delft University of Technology. His role in establishing and chairing the IEEE 802.11 Standards Working Group for Wireless Local Area Networks has led to him being referred to by some as the "Father of Wi-Fi". Hayes is a graduate of the Hogeschool van Amsterdam, where he studied electrical engineering.(4)

Father of Wi-Fi


IEEE 802.11

IEEE 802.11 is part of the IEEE 802 set of local area network (LAN) technical standards, and specifies the set of media access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) computer communication. The standard and amendments provide the basis for wireless network products using the Wi-Fi brand and are the world's most widely used wireless computer networking standards. (3)


Wi-Fi (Wireless Fidelty

Wi-Fi is a family of wireless network protocols, based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves.

MF293N - Wi-Fi Alliance

Wi‑Fi is a trademark of the non-profit Wi-Fi Alliance, which restricts the use of the term Wi-Fi Certified to products that successfully complete interoperability certification testing. As of 2017, the Wi-Fi Alliance consisted of more than 800 companies from around the world. As of 2019, over 3.05 billion Wi-Fi enabled devices are shipped globally each year. (2)


Wi-Fi Generations

Historically, the equipment has simply listed the versions of Wi-Fi using the name of the IEEE standard that it supports. In 2018, the Wi-Fi Alliance introduced simplified Wi-Fi generational numbering to indicate equipment that supports Wi-Fi 4 (802.11n), Wi-Fi 5 (802.11ac) and Wi-Fi 6 (802.11ax). These generations have a high degree of backward compatibility with previous versions. The alliance has stated that the generational level 4, 5, or 6 can be indicated in the user interface when connected, along with the signal strength. (2)

ZTE MF293N supports Wi-Fi b/g/n i.e. Generation 1/3/4.


VoLTE - Voice over Long-Term Evolution

ZTE MF293N supports VoLTE. You can connect a normal telephone for landline into RJ11 port. Insert the SIM into ZTE MF293N and turn on the device. Now you can dial the SIM card number and the connected phone will ring.

VoLTE is an LTE high-speed wireless communication standard for mobile phones and data terminals, including Internet of things (IoT) devices and wearables. VoLTE has up to three times more voice and data capacity than older 3G UMTS and up to six times more than 2G GSM. It uses less bandwidth because VoLTE's packet headers are smaller than those of unoptimized VoIP/LTE. VoLTE calls are usually charged at the same rate as other calls. To be able to make a VoLTE call, the device, its firmware, and the mobile telephone provider must all support the service in the area, and be able to work together. VoLTE has been marketed as HD Voice by some carriers, but this is not the same as the VoLTE standard. (5)
