Furthermore the number of channels envisioned in most wireless network schemes is still very small, and the range large (50-100 meters), so that the total number of mobile devices is severely limited.
此外，在大多数无线网络计划设想的管道数量仍然是非常小的，而范围大(50- 100平方米)，因此使得移动设备的总数量受到严格限制。
But even with this advantage, wireless devices offer a vast range of capabilities in terms of memory, processing power, battery life, display size, and network bandwidth.
但即使有这个优点，各种无线设备在内存、处理能力、电池寿命、显示屏大小和网络带宽等方面的能力差异还是相当大的。
Present technologies would require a mobile device to have three different network connections: tiny range wireless, long range wireless, and very high speed wired.
当前的技术需要移动设备有三个不同的网络连接：小范围的无线，远程无线和有线高速。
