According to a story in the Herald today, Xnet will soon begin offering a wireless internet service using Kordia's Extend network which has been in operation since November 2003:

Telecom have largely controlled the services offered on this network until now, hence the VoIP capability of each subscriber's wireless transceiver has remained dormant, but that is all set to change from July once WxC start offering Xnet Xtend.

Finally, those two RJ-11 ports on the Airspan transceiver will serve some useful function, and access to the bandwidth reserved for them will be unlocked.

Hopefully the combined offering of a VoIP service together with Wireless Broadband will accelerate uptake as it will allow rural dwellers to ditch their Telecom line along with all the electric fence noises and poor quality which are frequently present.  2000 subscribers on a service which cost more than $25 million to roll out is not a great return on investment, and the high cost of the service is largely to blame.  A $99 entry level is not a great selling point, and this will need to be addressed if any significant increase in uptake is to be gained.
