Frequently Asked Questions

What's the difference between HSDPA, HSUPA, WAP, GPRS and Wi-Fi?

HSDPA, which is short for High Speed Downlink Packet Access, is a third generation (3G) mobile technology that Telstra is using that carries high-speed data through the single national Telstra Next G™ Network.

HSUPA, which stands for High Speed Uplink Packet Access, is also a third generation (3G) mobile technology that delivers even faster uplink speeds through Telstra Next G™ Network.

WAP stands for Wireless Application Protocol. Internet pages, information services and games written using this protocol can be viewed on GSM or CDMA WAP compatible handsets.

GPRS is a data packet switching technology (the data is divided into small 'packets' to make more efficient use of the network) available within GSM coverage areas. Data transmission speeds are up to 40kbps**. Requires a GSM and GPRS compatible device.

Wi-Fi (Wireless LAN) uses the 802.11b/g wireless network standard to deliver internet and LAN services in distinct areas (Telstra Wireless Hotspots or your Home Wi-Fi range). Maximum data speeds of up to 11Mbps are possible, depending on coverage, location and capacity. Transmission speeds of 1Mbps are more typical. Requires a Wi-Fi enabled device.

NOTE: As with any radio system there are places inside the marked coverage areas where service may not work due to a variety of factors. For example, radio reception can be degraded or non-existent in certain places, particularly basements, lifts, underground car parks and large buildings. Reception can also be affected by mountains and tunnels.

** These are maximum achievable downstream data speeds. Upstream speeds over the applicable BigPond service will be lower than the downstream speeds. Actual user speeds, both upstream and downstream, will vary depending on user location, network capacity, mobile device used, transmission direction and external constraints (including, without limitation, the application in use).
