摘要

多址的选择/设计需要考虑许多因素。TDMA和CDMA都能够支持分组业务，例如GSM和3G/UMTS。分组访问更关注访问速度(通道请求和通道分配);更高的层需要合作(即减少层数)，访问的可观开销是不可避免的。

Wireless access technologies - tutorial

Selection/design of multiple access needs to consider a number of factors. TDMA and CDMA are both capable of supporting packet services e.g. GSM and 3G/UMTS. Packet access puts more concern on the speed of access (channel request and channel allocation); higher layers need to cooperate (i.e. reduce the number of layers) and considerable overhead for access is inevitable.
