WAP is an international standard for applications that use wireless communication. Its most common application is to enable access to the Internet from a mobile phone or a PDA. WAP sites are websites written in or converted to WML (Wireless Markup Language) and accessed via the WAP browser WAP websites are now considered outdated as most modern phones have web browsers with HTML support.

Wi-Fi is a WLAN (Wireless Local Area Network) technology. It provides short-range wireless high-speed data connections between mobile data devices (such as laptops, PDAs or phones) and nearby Wi-Fi access points (special hardware connected to a wired network). The most common variant of Wi-Fi is 802.11g, which is capable of providing speeds of up to 54Mbps and is backwards compatible with 802.11b (providing up to 11Mbps). There is currently a new standard in the works called 802.11n (offering twice the speeds of 802.11b) and there are already retail networking devices that support its draft specifications. Currently, there are no mobile phones that support the draft 802.11n specifications. Wi-Fi is much faster than any data technologies operating through the cellular network like GPRS, EDGE and even UMTS and HSDPA. The range covered by a Wi-Fi access point is from 30 to 100 meters indoors while outdoors a single access point can cover about 650 meters.

WiMax is the trade name for a family of new technologies related to the IEEE 802.16 wireless standards. Has the potential for very long range (up to 30 miles) and high speeds. The first versions were based on 802.16a wireless technology and designed for fixed applications only. Newer versions designed around mobility could make this a potential competitor for some 3G or 4G technologies.
