Wireless　networks　today　can　be　divided　into　several　phases,　the　first　voice　communication　is　based,　that　is　1g,　the　second　phase,　where　we　are　in　stage-based　data　traffic.　In　the　third　phase,　will　be　mainly　dominated　by　video,　the　need　for　new　ways　to　optimize　the　network　in　order　to　prevent　saturation.　The　future　is　4G　era.　Now,　based　on　3G　mobile　communication　technology　has　been　successful　in　the　global　implementation　of　standardized　and　up.　4G　standards　battle　has　been　engaged　in　fierce.　For　now　it　seems　3G　technology　in　the　WiMAX　and　LTE　will　be　strong　competitors　in　the　future　4G　standards.　In　this　paper,　we　will　talk　about　the　4G　technology　standard,　WiMAX　and　LTE　the　basic　characteristics　of　the　key　aspects　of　technology　and　application　prospects　of　WiMAX　and　compare　LTE　and　the　development　of　future　wireless　networks.
