Ultra-High-Performance G.hn Modules

For ultra-high-performance PLC applications, the G.hn power-line communication module MOD957 is recommended. The G.hn PLC module is fully ITU-T G.hn standards compliant, and support mesh topology with plug and play functions. The maximum PHY rate is 1Gbps, and the maximum throughput exceeds 700Mbps. Therefore this module can enable ultra-high-speed applications such as 4K video streaming, virtual reality, or home networking and WiFi coverage.

High-Performance PLC Modules

For high-performance Ethernet or IP over power-line applications, the PLC module MOD923 is recommended. This power-line communication module supports up to 200 Mbps PHY rate, and up to 100Mbps uni-directional throughput. MOD923 has been applied in lots of projects worldwide, proving its maturity and stability.

Mass Connectivity PLC Modules

For power-line communication module applications involving hundreds of nodes, MOD927 is recommended. This module has a maximum PHY rate of 20Mbps, and support aggregate data rate in the range of 10Mbps. It can be deployed for large scale IP-based mesh networks based only on existing wires including DC or AC power-line, serial cables, or twisted-pair/2-wire. Applications such as building automation networks, smart grid networks, distributed energy storage management network, or EV charging station networks, can all benefit from this module by reusing existing power-line or other cables.

Applications

Xingtera Power-Line Communication

There are many types of power-line communication technologies available over the past decades. However, most legacy technologies have their own disadvantages. There are generally 3 types of PLC technologies:

  • Narrow-Band PLC
  • High-Speed PLC
  • Ultra-High-Speed PLC

Narrow-Band PLC (NB-PLC) is widely used for smart grid applications including AMR and AMI. Although it supports the best coverage because of its higher and more concentrated Tx power, the main issue with NB-PLC is its very low data rate and its lack of IP support. Therefore NB-PLC isn’t compatible with most modern technologies based on Ethernet or IP network. For next-generation smart grid applications, distributed energy applications, or clean energy management, the overall management is always based on IP protocols, and usually, a cloud (public or private) is employed for easier monitoring. The legacy NB-PLC is therefore outdated and we believe it will transform gradually to IP-based high-speed PLC technologies.

High-Speed PLC is more popular these days. However, the definition of “high-speed” varies a lot among different power-line communication module or solution vendors. In Xingtera, we define “high-speed” as anywhere between 10Mbps to 100Mbps. A lot of legacy “high-speed” PLC modules or solutions support up to 1Mbps data rate. Although 1Mbps is probably enough for meter reading, it lacks the flexibility to deploy further applications. With users now very concerned about energy saving, utility companies are leaning towards providing more information, even real-time data to every end customer. Therefore the higher bandwidth of power-line communication solution is essential in ensuring the smooth experience of data gathering. Moreover, utility companies will be able to re-use the power grid for non-conventional network coverage such as smart city sensor networks, street lights or EV chargers management, and emergency announcement.

Another issue of legacy high-speed PLC technologies is the number of nodes support. With more and more devices and terminals now going IP, the ability to connect all such devices and keep them online is key for an efficient power-line communication network. Considering this unique requirement, Xingtera’s power-line communication modules can now support up to 1,000 nodes online at the same time. This greatly reduces the common limitation of PLC deployments and makes the installation of such networks very straightforward.

For ultra-high-speed power-line communication, it usually requires 500+Mbps throughput to enable many applications with extremely high bandwidth requirements, such as HD/4K/8K video streaming or XR (VR/AR). There are very few PLC technologies available to achieve this. G.hn is the only major PLC standard supporting up to 2Gbps PHY rate over 100MHz MIMO technology. By utilizing 2 power-line channels through live, neutral, and ground pins, G.hn provides astounding throughput and extra reliability. Xingtera offers G.hn power-line communication modules to meet applications where bandwidth is really important.

In sum, depending on the different requirements of each application, different types of power-line communication modules or solutions will be recommended. Xingtera offers a complete portfolio of PLC modules, as well as a dedicated engineering team to provide technical support and customization. Xingtera has shipped PLC chipsets, modules, and products to customers in all continents, and will become the best PLC technology partner to you.
