回复 小丸子walkstars 的帖子
谢谢丸子，另外您上面引用的网友的澳洲频段好像也有些错误。
1. 2G
Telstra, Optus 和vodafone 都用的900MHz和1800MHz (实际上都是Telstra的网络)
2. 3G 澳洲三大电信商用的都是WCDMA, 频段：
Telstra 850/2100
Optus 900/2100
Vodafone 850/900/2100 (900是并购的 3 mobile 的，以前澳洲运营商有4个)
3. 4G LTE 频段
Telstra 900/1800/2100
Optus 1800/2300
Vondafone 900/1800
Optus， vondafone 是商业网络，他们 的3G， 4G网络主要集中在城里，因为人口主要集中在城里，有人用才能挣钱。
Telstra 是国家网络，肩负建设 National broadband network （NBN）的任务,国家给补贴，挣不挣钱都得建。 Optus和vodafone租借 Telstra的某些地段的频率，比如 2G network是租给另两家都用的。Oputs 和vodafone 再不太偏僻的地方打电话基本没有太大问题，就是上网不怎么样，有些地方连不上3G
2G, other wise known as GSM, is standard on almost all phones (except CDMA phones in the USA). Most new phones come with quad band GSM support. A quad band GSM phone supports 850, 900, 1800, and 1900MHz.
2G is old technology and provides a fall back position when 3G coverage is unavailable.
Australian 2G bands:
•900Mhz (Telstra, Optus & Vodafone)
•1800Mhz (Telstra, Optus & Vodafone)
3G
There are several 3G networks operating in Australia. 3G frequencies are usually specified as UMTS/HSDPA or WCDMA frequencies on the mobile phone specifications.
Australian 3G bands:
•850MHz (Telstra, Vodafone) – Exclusive 3G band
•900MHz (Optus, Vodafone) – available in most metro areas
•2100MHz (Telstra, Optus, Vodafone) – Exclusive 3G band
4G
Australia is currently using these LTE bands (LTE bandmask in brackets):
•2100Mhz (B1) FDD (0000000000000001) – Telstra (3G spectrum)
•1800Mhz (B3) FDD (0000000000000004) – Telstra, Optus, Vodafone
•900Mhz (B8) FDD (0000000000000080) – Telstra, Vodafone, Optus (utilises spectrum previously used by 2G)
•2300Mhz (B40) TDD (0000008000000000) – Optus (Vivid wireless spectrum)
To follow late 2014:
•2600Mhz (B7) FDD (0000000000000040) – Telstra, Optus,
•700Mhz (B28) FDD (0000000008000000) – Telstra, Optus
