3G
There are several 3G networks operating in Australia. 3G frequencies are usually specified as UMTS/HSDPA or WCDMA codecs on the mobile phone specifications.
Australian 3G bands:
850MHz (B5) – Telstra, Vodafone
900MHz (B8) – Optus, Vodafone – available in most metro areas on Optus, with both Optus and Vodafone re-farming the 2G 900 spectrum in regional and rural areas
2100MHz (B1) – Telstra, Optus, Vodafone
4G
Australia is currently using these LTE bands (LTE bandmask in brackets):
2100MHz (B1) FDD (0000000000000001) – Telstra (a handful of sites), Optus (Darwin, Tasmania)
1800MHz (B3) FDD (0000000000000004) – Telstra, Optus, Vodafone
850MHz (B5) FDD (000000??????????) – Vodafone (refarming 5Mhz of this frequency to be 4G across all metro areas, claiming by end of 2014)
2600MHz (B7) FDD (0000000000000040) – Optus, Telstra. (TPG have a license but have not announced plans for it.)
900MHz (B8) FDD (0000000000000080) – Telstra (a handful of sites, utilises spectrum previously used by 2G)
700MHz (B28) FDD (0000000008000000) – Telstra, Optus (switched on early in a couple of cities, will be widespread in 2015)
2300MHz (B40) TDD (0000008000000000) – Optus (Vivid wireless spectrum), NBN
3500MHz (B42) TDD (????????????????) – Optus, NBN (trials at this stage)
对比坚果的参数
网络制式 支持频段
4G 联通 FDD-LTE B1 / B3 / B7
移动 TDD-LTE B38 / B39 / B40 / B41 ( 注:B41 仅支持中国频段 )
3G 联通 WCDMA B1 / B2 / B5 / B8
移动 TD-SCDMA B34 / B39
2G 移动/联通 GSM B2 / B3 / B5 / B8
结论:
3G没有问题。
4G因为支持FDD(B3),所以理论上几个大的公司也都能用。 |
