The mobile browser usually connects via the cellular network, or increasingly via Wireless LAN, using standard HTTP over TCP/IP and displays web pages written in HTML.WML and HDML are stripped-down formats suitable for transmission across limited bandwidth, and wireless data connection called WAP.The first mobile browser for a PDA was PocketWeb[1][2] for the Apple Newton created at TecO in 1994, followed by the first commercial product NetHopper released in August 1996.[4][5] A British company, STNC Ltd., developed a mobile browser (HitchHiker) in 1997 that was intended to present the entire device UI.HitchHiker is believed to be the first mobile browser with a unified rendering model, handling HTML and WAP along with ECMAScript, WMLScript, POP3 and IMAP mail in a single client.ProxiWeb[9] was a proxy-based Web browsing solution, developed by Ian Goldberg and others[10] at the University of California, Berkeley and later acquired by PumaTech.Distinct from a mobile browser is a web-based emulator, which uses a "Virtual Handset" to display WAP pages on a computer screen, implemented either in Java or as an HTML transcoder.
