22 October 2013, Shenzhen, China – ZTE Corporation (“ZTE”) (H share stock code: 0763.HK / A share stock code: 000063.SZ), a publicly-listed global provider of telecommunications equipment, network solutions and mobile devices, has launched a VDSL VoIP gateway, the ZXHN H368A, which supports the latest 802.11ac Wi-Fi standard. With its concurrent support for the 2.4GHz (gigahertz) and 5GHz bands, the product enables wireless home networks to deliver bandwidth-hungry high-definition video services at Gbps (gigabits per second) speeds.

The growth of services such as IPTV (internet protocol television) and OTT (over the top) video and the proliferation of mobile devices, including smartphones and tablets, has led users to demand increasingly higher bandwidth for in-home wireless networks. 2.4GHz Wi-Fi is restricted by limited spectrum resources and interference signals; so is not suitable for carrying high-definition video services which require high bandwidth and a stable connection. By contrast, the 5GHz band has approximately seven times the spectrum resources of the 2.4GHz frequency, which results in increased bandwidth and reduced interference. The latest 802.11ac standard for 5Ghz Wi-Fi released by the IEEE (the Institute of Electrical and Electronic Engineers) allows for the transmission of multiple video channels.

The ZXHN H368A supports dual-band concurrent Wi-Fi, with total rates at the physical layer reaching 1.6Gbps, thanks to its ability to operate on both the 2.4GHz and 5GHz bands. In the 5GHz band, the gateway supports 802.11ac MIMO3x3, delivering speeds of up to 1.3Gbps at the physical layer and enabling operators to provide video services such as IPTV. In the 2.4GHz band, the product supports 802.11n MIMO2x2, with its physical-layer rate of 300Mbps (megabits per seconds) allowing user terminals to access the internet. In the absence of a dual-band user terminal, the 2.4GHz band affords better compatibility with devices not supporting the 5Ghz band.

The VDSL2/GE dual-uplink technology allows the ZXHN H368A to be deployed in VDSL and FTTx scenarios, while VDSL2 bonding lets it provide higher access speeds. The gateway also supports G.Vector and can work with a DSLAM to cancel crosstalk, enabling it to reach the speed limit of VDSL2 technology. In the downlink, the product features four GE LAN ports in addition to dual-band concurrent Wi-Fi capability.

To date, ZTE’s broadband CPE devices have been deployed in more than 80 countries and regions, with shipments to major European operators growing more than 100 per cent year-on-year. This includes large deployments in China, France, Germany, the Netherlands and Spain.
