In this paper, the downlink throughput capacity of hybrid wireless networks is mainly studied. Multiple-input multiple-output (MIMO) technology is assumed to be equipped on the base station and nodes to improve communication performance and increase the whole network throughput. A wireless network is also set up, with a wired network of base stations to support the remote communication of wireless nodes. In order to overcome the inter-cell interference, the frequency reuse technology is adopted. Under the favorable propagation condition, MIMO significantly mitigates the effect of fading between the node antenna and the base station antenna. We first analyze the downlink outage throughput capacity in slow fading scenarios and get the close-form outage capacity. Then, we analyze the ergodic throughput capacity over fast fading channel and get the ergodic capacity in both low SNR and high SNR scenarios. Finally, the availability of MIMO technology is proved by computer simulation.
