Alternative to Ethernet: What Is Nessum, the Next-Generation IP Communication Technology That Utilizes Existing Wiring?
The IP Network Revolution—and a Commonly Overlooked Alternative
In the fields of multi-unit residential intercom systems, building automation, etc., the shift toward IP-based solutions is accelerating. Devices such as video intercoms, HVAC systems, and sensors are increasingly being connected via IP networks, enabling remote maintenance, cloud integration, and dramatically enhancing system convenience, security, and scalability.
As this transformation expands, engineers and decision-makers often turn first to well-known technologies: Ethernet or 10BASE-T1L (Single Pair Ethernet) for wired connections, and Wi-Fi for wireless. These are familiar choices—but they come with challenges. Wired solutions require new cabling, and wireless signals cannot be reached in certain environments.
That’s why it’s time to pay attention to a promising alternative: Nessum, a next-generation communication technology that deserves serious consideration.
The Realistic Hurdles of Ethernet Deployment
According to a survey by HMS Networks, 71% of newly connected nodes in industrial networks use Ethernet (compared to 22% for fieldbus and 7% for wireless). Ethernet is dominant, and its widespread adoption means a rich ecosystem of corresponding devices. However, when it comes to retrofitting existing buildings and multi-unit residences—many of which still use legacy, non-IP communication networks—Ethernet presents several challenges:
- High costs associated with new cabling work
- Securing skilled labor for installation
- Impact on residents in multi-unit residences and businesses/employees using office spaces
To overcome these obstacles, what’s needed is a cost-effective solution that enables network deployment without rewiring—one that minimizes construction time and expense.
What Is Nessum? A Next-Gen IP Communication Technology That Utilizes Existing Wiring
Nessum is a next-generation communication technology designed to build long-range, wide-area IP networks using existing wiring infrastructure. Whether it’s twisted pair cables, coaxial cables, or power lines, Nessum can upgrade virtually any type of cable into a communication medium—without being limited by cable type or topology. This topology-free approach enables cost-effective network deployment, even in complex environments. With built-in Layer 2 switching capabilities, Nessum integrates seamlessly with IP networks.
It supports transmission speeds ranging from several Mbps to tens of Mbps over distances of several kilometers. Each Master device can connect up to 1,024 nodes, and its multi-hop technology enables the building of large-scale networks. Robust noise resistance and flexible bandwidth configuration further ensure reliable and resilient communication.

Example: Building an IP Network Using Nessum
When building an IP network using existing two-wire cables and Nessum technology, there are two main approaches:
- Embed the Nessum device into your product
- Connecting the Nessum adapter to your existing product with Ethernet Interface
In this article, we explore examples using a multi-unit residential intercom system—an area where demand for IP-based solutions is rapidly growing.
In the case of embedding the Nessum device into the intercom unit, rewiring is not necessary. Installation is straightforward: replace existing analog communication units with Nessum-compatible ones.
Alternatively, if you already have Ethernet-based products, you can connect them via a Nessum-to-Ethernet adapter. This method allows you to utilize the existing wiring infrastructure while deploying Ethernet-based products. However, keep in mind that you’ll need to consider space for the adapter and ensure a power supply.
Case Study: Building a Network Cost-Effectively Using Existing Wiring
One of the key advantages of Nessum is to utilize existing wiring infrastructure, which can significantly reduce both the time and cost required for building a network. Here's an example:
In a student dormitory in Japan, Nessum was used to establish an internet environment. Initially, the plan was to build the network using Ethernet. However, by upgrading the existing power lines into communication lines with Nessum technology, the project achieved a 60% reduction in cost and an 85% decrease in construction time.

Why Nessum Still Matters—Even If You Already Use Ethernet
If you're already developing or selling Ethernet-based products, Nessum isn't necessarily a competing technology—it can be a complementary one. As we've discussed, Nessum excels in scenarios where existing buildings or multi-unit residences need to upgrade from analog to IP-based communication networks.
A hybrid strategy can be especially effective: use Ethernet where new wiring is feasible, and deploy Nessum where maintaining existing infrastructure is essential. This approach not only expands your market reach but also enables you to offer IP solutions in environments that were previously considered unsuitable.
Nessum—A Compelling Alternative to Ethernet
Nessum is a next-generation IP communication technology that enables flexible and cost-effective network deployment by utilizing existing wiring infrastructure. Even in environments where new cabling is difficult or impractical, Nessum makes IP network construction possible without rewiring.
By complementing Ethernet or 10BASE-T1L according to the installation environment, Nessum becomes a powerful option for expanding the reach of your products and services. Whether you're upgrading legacy systems or entering new markets, Nessum offers a practical solution to meet the growing demand for IP-based connectivity.
As the need for IP migration continues to rise, we encourage you to explore how Nessum can enhance your network strategy.
