5G与6G的异同

5G和6G是蜂窝网络技术的不同发展阶段，它们在速度、频谱使用、应用场景、延迟和安全性等方面存在一些明显的异同。

异同点：

频谱使用：5G网络使用的频段相对较低，主要在24 GHz至66 GHz的低频段、中频段或高频段毫米波中运行。而6G网络将使用更高的频段，在30 GHz至3000 GHz的毫米波至辐射范围内运行，这将提供更大的带宽容量和更广的覆盖范围[2]。

速度：5G网络相较于4G LTE有了显著的速度提升，提供高达每秒10吉比特的理论速度，比4G LTE-Advanced的300Mbps理论最大速度快30多倍。而6G网络预计将提供比5G快100倍的理论最大速度，达到每秒206.25吉比特[2]。

应用场景：5G网络主要支持智能手机、电脑、电视以及智能穿戴、家居等设备的联网。而6G网络将实现万物皆可互联的目标，将应用于智能家居、自主交通系统、医疗保健等创新用例，为自动化为重点的智能社会提供前所未有的速度和低延迟[2]。

延迟：5G和6G网络都比4G LTE具有更低的延迟，但6G网络利用更高频段的无线频谱，可以实现更短的响应时间，从而允许设备之间更快的传输时间[2]。

安全性：5G和6G网络都带来了安全威胁，但6G网络可能带来更大的风险。由于6G网络具有更大的攻击面和更复杂的范围，可能引入新的安全漏洞，因此必须采取措施加强其安全协议，并确保与网络技术的最新发展保持同步[2]。
