I bought into Vividwireless knowing that it was extremely likely that Optus would shut the WiMax service down. I was actually kind of hoping that they would shut it down and offer a similar data plan for the same price on their 4G network.
But really, the service I’ve had with Vivid is miles ahead of what I got on Telstra ADSL. WiMax had good speeds at quiet times, but the speed did drop a bit at peaks. Them when they migrated us over to LTE it was great. I was getting a solid 10Mbps for months until more people jumped on the network.
Now it looks like Optus is just going to grandfather the Vivid plans and offer new fixed wireless services on the 5G network starting early next year.
I always found it odd that Vivid kept their operations and systems mostly separate from Optus, including their website (which looks like it hasn’t been updated since 2012). They also have their own support forum staffed by two people (who provided very decent advice).
