我们扩展的无线网络的传输容量的概念，广播的情况下，因此定义的广播传输容量的无线网络的广播节点的空间密度，广播节点的邻居的平均数量，和信息速率的产品，同时考虑系统内干扰和系统间干扰从多个共存的异构无线网络。在期望信号和干扰信号的一般衰落条件下，得到了广播传输容量的上界的封闭形式，并以近似封闭形式给出了精确结果。
We extend the concept of transmission capacity of a wireless network to the broadcast scenario, and consequently define the broadcast transmission capacity of a wireless network as the product of the spatial density of broadcasting nodes, the average number of neighbors of a broadcasting node, and the information rate, considering both intra-system interference and inter-system interference from multiple coexisting heterogeneous wireless networks. Under general fading of desired signal and interfering signals, upper bound on the broadcast transmission capacity is obtained in closed-form, and the exact result is expressed in nearly closed-form.
