In　this　paper,　we　study　some　transmission　capacity　theories　of　hierarchical　wireless　mobile　ad　hoc　networks　(H-MANET).　Firstly,　we　present　the　structural　protocol　model,　node＇s　mobility　tracking　model　of　H-MANET.　Secondly,　we　propose　and　prove　a　critical　inequality　of　transmission　capacity　of　H-MANET.　Lastly,　we　propose　and　prove　a　gradual　probabilistic　quality　and　the　specific　expression　of　expectant　availability　of　transmission　capacity　of　H-MANET.　The　results　enrich　the　theory　of　Kumar,　GP　(2000)　and　the　information　theory　of　wireless　networks　in　certain　degree.
