The invention discloses an ultra-short wave radio communication network system in high-speed data transmission. The system comprises M antennas, M ultra-short wave radios and M communication controllers, wherein the M antennas are in wireless communication connection, and M antennas are respectively and correspondingly connected with M ultra-short wave radios in a two-way communication way; the M ultra-short wave radios are respectively and correspondingly connected with M communication controllers in the two-way communication way; the M communication controllers are respectively used for acquiring voice and data, and respectively and correspondingly distributing media access control IP addresses for M ultra-short wave radios and performing the time-slot division, thereby respectively obtaining M IP addresses and Q time slots; the M IP addresses and M ultra-short wave radios are in one-to-one correspondence and different from each other; the Q time slots is the summation from the Q1 time slot to QM time slots, wherein the time slot number contained in the i-th ultra-short wave radio after the time slot division is denoted as Qi, the Qi is an integer greater than 0, i belongs to {1,2,...M}; the Q time slots respectively distribute different work channels for M ultra-short wave radios, wherein the work channel is a time channel for transmitting/receiving the voice and data.
