Ultrawideband is a new technology in high speed wireless communication, but the band′s width will fall into the frequence range of GPS, cause interference to GPS signal.
超宽带是高速无线通信的新技术，然而其较大的带宽会落入GPS频带范围内，造成对GPS信号的干扰。
The band width of the radio-frequency signal for the spread spectrum communication can be spreaded to several times or even thousands of times the band width of the information signal.
扩频通信的射频信号频带宽度，可扩展到信息信号频带宽度的数倍乃至数千倍。
At present, using the second-generation or the second-generation half mobile communication network, the limited network band width becomes the bottleneck of guarantee quality of map service.
目前，使用的是二代或二代半移动通信网络，有限的网络带宽成为保证地图服务质量的瓶颈。
