Year 2007.
What is with it now?

There are only TerraNet test networks in operation today. There is at least one commercial implementation planned during 2008, and we will publish more information here on TNMC at a later date.

There are no productified handsets available ‘on the shelf’ or in production at this time. The technology itself is developed, demonstrated in a laboratory environment and in test networks, and is already included in implementation projects that are scheduled for completion in 2008.

Congestion, or traffic overload, can happen in any mobile phone network where the use of the network is excessive, or where the network is not scaled to fit the amount of users. There is of course a limitation as regards the data flow in each TerraNet handset. The TerraNet technology strives to distribute the traffic over the full network to minimizing the risk of congestion, by e.g. using TerraNet HelperNodes to offload the handsets’ load of forwarding.

Mobile phone manufacturer Ericsson had invested around £3m in TerraNet around 2007.
