What do the bands mean? which is best?
Each band has its own different properties, let’s start with the lower bands and work our way up to higher ones.
700Mhz, Band 28
This has been widely touted as the "Water front" of all bands as it is the lowest band available to the mobile industry in Australia. This frequency was once use by Terrestrial TV services, but with the introduction of Digital TV which uses bandwidth much more efficiently due in part to digital compression, as a result this band was freed and released to the mobile industry. It has 1.2x the range of the previous best band which was 850Mhz, and has great building penetration. The downside to 700Mhz is there just isn’t enough of it, so although you will get great coverage in many more places don’t expect gigabit speeds on this band alone.
Allocation of this band has been setup to be nationwide, Telstra owns the most with a 2x20Mhz block and Optus owns 2x10Mhz. Both Telstra and Optus both have fairly wide coverage of this band, however Optus is much further along in their rollout as of the beginning of 2017 claiming 95% population coverage. Vodafone has purchased a 2x5mhz block of this band but has not yet rolled out any supporting towers, TPG purchased the remaining 2x10mhz blocks at quite a cost paying almost twice what Telstra and Optus originally for the same amount. Telstra was prevented from participating in the final auction round as it already purchased the maximum allowable amount.
lower band一般讲穿透/覆盖好 . 但是速率不会太高.
比较适合偏远地区.
