This downloadable coverage map contains a geographic model of Telstra 4G mobile broadband data speeds within the Torres Strait Council Region in Queensland. To ensure the highest level of accuracy the map includes all 36 Telstra 4G LTE transmitters from 19 towers within and immediately surrounding the region. Prior to digital delivery the model we be re-checked for network changes, ensuring the model has the latest publicly available data included.
Most of the region uses a single Band 28 700 MHz carrier to provide 4G services throughout the island communities up to a theoretical peak speed of 180 Mb/s, although most of the islands are linked to Thursday Island by 6 / 6.7 GHz microwave which imposes significant restrictions on backhaul capacity. The more easterly communities of Stephens, Darnley, and Maer Islands are linked by multiple microwave hops which further impacts capacity and reliability.
Connected to the mainland, Thursday Island has the region's fastest 4G network with B28 and B7 carriers, with performance comparable to that of Bamaga on the mainland.
The model is coloured in a traditional heat-map from blue to red, representing peak LTE downlink data rates from 0 to 600 Mb/s. Peak data rates represent the maximum achievable data rate at any given location.
The Torres Strait 4G mobile broadband map can be used to identify service availability, blackspots, estimate maximum data speeds, and predict LTE coverage out to sea. The model also shows Telstra coverage available from Papua New Guinea mainland. It covers the following major communities:
- Bamaga, Badu, Boigu, Coconut, Darnley (Erub), Daru, Dauan, Hammond, Horn (Ngurupai), Injinoo, Mabuiag, Maer, Moa, Prince of Wales (Muralug), Saibai, Stephens, Sue, Thursday (Waiben), Wednesday, Yam, Yorke (Masig)
This very large model has been generated to 4 metre grid accuracy for major islands and 30 metre grid accuracy for minor islands and PNG using a combination of LiDAR, SRTM and vegetation clutter datasets, and uses ITU standard propagation models that has been optimised for Australian terrain and vegetation characteristics.
The model uses the Cradlepoint IBR1700-1200 as its modelled UE (Cat-18, 5CCA, 4x4 MIMO).
