If your mobile phone is critical for work and you're having trouble with reception inside your office, this might be of interest.
Optus has announced that it had switched on its first 700MHz 4G services in the Darwin and Perth central business districts.
700MHz service was expected to start in January 2015, but the carriers have been given approval to start commercial trials ahead of the full launch.
Optus was first out of the blocks, but within hours Telstra revealed that its initial commercial trials would begin "in the coming weeks" in Perth, Fremantle, Esperance, Mildura, Mt Isa and Griffith.
Telstra went a step further by announcing that its trial will include 4G Advanced, which provides double the (already fast) speeds provided by existing 4G services, and as Mike Wright, Telstra Group Managing Director Networks, put it "his combination of two spectrum bands also doubles the 4G capacity of our network, which means it can support more customers, using more devices, doing more of the things they love at the same time."
The main benefit of 700MHz - which has become available to mobile carriers following the move from analogue to digital TV - is that it carries further, whether that's in open air (a stronger signal is available further from the base station) or indoors.
700MHz penetrates buildings better, so the signal is less likely to drop out when you're in a lift or a reinforced concrete car park, and if you currently need a repeater to get decent reception in your home or office it may become redundant once 700MHz reaches your area.
The downside is that very few phones currently on the Australian market support 700MHz operation. To the best of our knowledge, the only choices are the HTC One M8 and the Samsung Galaxy S5, and neither handle 4G Advanced operation.
That situation will change over the coming months as the carriers and handset vendors expand their ranges ahead of the national launch of 700MHz service slated for January 2015.
