SD-WAN or internet access method

What is it?

How can it be used?

National Broadband Network (NBN)

The NBN is the first national wholesale-only network built in Australia available in both residential- and business-grade form. The NBN replaces Australia’s analogue phone lines, ADSL broadband and other data telecommunications technologies utilising copper wire access from the street. NBN is physically connected to a premise using a mix of fibre, copper wires and coaxial cable from the Foxtel & Optus networks. The NBN is used as an access method by Brennan IT for both SD-WAN, fully Private WAN, Business Internet connections and residential-grade connections to business locations like small retail stores. NBN Business is suitable for some locations and the maximum viable throughput Mbps varies depending on the access delivery type and specific location. Since PSTN phone lines are replaced by the NBN, businesses must move to a VoIP based fixed phone line or Hosted PBX phone system, which Brennan IT can assist you with.

Commercial Fibre Optic Ethernet

Reliable, scalable high-speed symmetric business grade fibre optic data network access to your SD-WAN or internet delivered over fibre optic cables. The fibre optic ethernet is physically provisioned by wholesale carriers like Telstra Wholesale, Optus Wholesale, AAPT/TPG, Vocus, Superloop, Spark New Zealand, and other global carriers. Fibre Optic Ethernet access technology should be the default and preferred primary choice for most business locations using SD-WAN, pure WAN and direct internet access. Speeds range from 1Mbps-10Gbps symmetric.

Fixed Wireless Ethernet

Fixed Wireless Ethernet is a data connection delivered by placing a small radio transmitter dish on the roof of your business premises. This transceiver connects directly to one of a network of base stations that then connect to a fibre optic backbone to deliver a high speed wireless connection. Like other access technology methods, it can be used for SD-WAN and Internet access. Fixed Wireless Ethernet can be used to establish high-speed, cost-effective data connections where fibre optic build is cost or time prohibitive. This data access method can also be used as an effective business continuity solution to automatically take over when a primary data connection suffers an outage. Fixed Wireless Ethernet is highly scalable, offering bandwidths from 1Mb/s all the way to 1000Mb/s. Coverage is available in Australian metropolitan areas and many regional centres, but is subject to feasibility.

Mobile Broadband 4G / 3G

The ability to connect to your SD-WAN or simply the internet wherever there is Telstra 4G mobile broadband network signal. We deliver this service via a managed router with integrated mobile broadband modem and SIM card inserted, not via a USB dongle. Typically used as an automated failover/backup SD-WAN or internet access method for business trading continuity. This method is also great to get a new site up and running quickly whilst fibre or NBN access is being built, before then switching it to be a failover.


ADSL is residential-grade, entry-level access alongside PSTN phone lines. The ADSL network is used today as an SD-WAN, pure private WAN or Internet access method, but is being quickly replaced by the NBN and is expected to be completely retired in Australia by 2022. ADSL would typically be used for home offices, or very small sites that have low requirements for download/upload speeds. Examples could be small retail stores or warehouses with just one computer. We only suggest ADSL access for organisations as a last resort.
