Bandwidth limits on individual users in busy times

 That would appear to suggest that while the number of users on some cells peaked at 60, the distribution of users among active cells was not uniform. Now, NBN Co's spokesperson said, "with 342,000 customers on the fixed wireless network, there are now approximately 19,000 cells" - which gives an average of 18, or 19 with likely rounding errors. Recently-added cells have been targeted at areas and users that experience particularly slow uplink speeds.

Outside of increasing the number of cells, NBN Co is also deploying carrier aggregation “to improve load balancing across available spectrum and enhance single user data rates”, and exploring the use of newer antenna technology and high-capacity backhaul. It has also proposed the introduction of bandwidth limits on individual users in busy times, enforcing a fair use policy.

The updates on congestion activities came as NBN Co announced the results of tests of millimetre-wave 5G technology, which may be deployed in future upgrades of the fixed wireless network. NBN Co claimed to have “achieved a world record for long-range 5G transmission using mmWave”. In live testing at an what do computer engineers do proof of concept site near Mortlake, Victoria, NBN Co and its technology partners, Ericsson, Qualcomm Technologies and Casa Systems, achieved a stable 5G mmWave transmission of close to 1Gbps at a distance of 7.3km, double the distance recorded at the site just three months ago, and a new record globally,” it said.
