According to Netgear officials, this is the first time that cable internet customers have been offered the combination of a DOCSIS 3.0 modem with AC1900 WiFi.

AC1900 refers to the C6300BD's dual-band support for nominal speeds of 600Mbps at 2.4GHz (802.11n) and 1300 Mbps at 5GHz (802.11ac).

Like some other 802.11ac devices, the C6300BD supports beamforming. This technology takes advantage of MIMO (multiple input, multiple output) to transmit the radio signals in the direction of individual devices for improved throughput and range.

"With more customers relying on Wi-Fi to connect up portable devices like laptops, smartphones and tablets to the internet, Wi-Fi quality has never been so important," said Telstra director of connected home, Alan Crouch.

"The world's first Telstra Gateway Max puts our customers at the forefront of in-home Wi-Fi technology and gives improved broadband reach and quality throughout the home with the introduction of the latest ac Wi-Fi standard and ultra-fast 1900Mbps Wi-Fi speeds."

Real-life Wi-Fi speeds are normally significantly lower than the theoretical maximums.

Other features include DOCSIS 3.0 bonding, a four-port Gigabit Ethernet switch, a USB 2.0 port, and a Gigabit Ethernet WAN connectivity port for flexible WAN connectivity options (eg, in case you are in one of the lucky areas that have or will get the NBN FTTH service). Quality of Service support prioritises audio and video streaming and gaming traffic over less time-sensitive data.

"These gateways are the first in a range that will be compatible with the Telstra Wi-Fi Network," added Mr Crouch, referring to the carrier's plans to create one of the world's largest Wi-Fi networks largely by allowing its customers to share their fixed-line connections with others.

"If you have one of these new gateways you'll be able to update the software next year to join the Telstra Wi-Fi community," he said.
