Telecom New Zealand has introduced carrier aggregation (CA) technology on six of its 4G mobile sites in Auckland, in association with technology partner Huawei. Telecom expects to have CA-capable devices commercially available on its network by the end of 2014, or early next year; the CA technology utilises a 20MHz block in the 1800MHz band and 20MHz in the 2600MHz band. Chief operating officer David Havercroft commented: ‘Carrier aggregation on our network allows for theoretical peak speeds of 300Mbps, and our testing has seen speeds on live sites of up to 260Mbps download. This is roughly double the theoretical peak speeds on our existing 4G network, and more than seven times the theoretical peaks available on 3G’.
Telecom launched its 4G Long Term Evolution (LTE) network in November 2013 in Auckland, Wellington and Christchurch. The telco recently announced that it intends to extend its 4G capability to a number of other New Zealand towns over the next few months, including Dunedin, Rotorua, Blenheim and Nelson.
