TP-Link Deco P7: Cheap And Powerful Powerline Wi-Fi 5

The TP-Link Deco P7 is a unique addition to TP-Link’s Deco lineup, offering a hybrid solution that combines mesh Wi-Fi with powerline networking. The P7 is designed for homes where Wi-Fi coverage may struggle due to thick walls, multiple floors, or long distances. With this device, TP Link addresses one of the key issues in mesh networks — weak signals between nodes — by adding powerline communication as a backhaul option to ensure stable and reliable connectivity.

In this article, we’ll explain mesh Wi-Fi, how the Deco P7’s powerline backhaul makes it stand out, and cover everything from the unit’s specifications to its ideal use cases and considerations for buyers.

Understanding Mesh Wi-Fi

Mesh Wi-Fi is designed to eliminate dead spots and provide consistent internet coverage throughout your home. Unlike traditional routers, which send signals from a single point, mesh systems use multiple units (or nodes) placed around your home. Each node communicates with the others, creating a seamless network. As you move through your house, your device connects to the node with the strongest signal, without any noticeable drop in speed or coverage.

In simple terms, imagine Wi-Fi like a lighthouse sending signals. A traditional router is just one lighthouse, meaning its light may dim the farther you go. Mesh Wi-Fi adds more lighthouses (nodes) so that the light (Wi-Fi signal) is evenly distributed throughout your home, ensuring all corners are covered.

What Sets the TP Link Deco P7 Apart?

What makes the TP Link Deco P7 stand out from other Deco units is its powerline backhaul feature. While most mesh systems rely solely on wireless communication between nodes, the Deco P7 uses your home’s electrical wiring to create a wired connection between the units. This feature is known as powerline networking.

What is Powerline Networking?

Powerline networking allows devices to communicate with each other through your home’s existing electrical wiring, acting as a substitute for running Ethernet cables. This means that even if one of your mesh units is placed far away from the others, the signal can still be strong and reliable, as it’s transmitted through the electrical wiring rather than over the air.

Here’s how it works:

1. Each Deco P7 unit plugs into a standard electrical socket.
2. The units use your home’s power circuit to send data between nodes.
3. This means that instead of relying solely on Wi-Fi for the connection between nodes, the Deco P7 can send data over your electrical wiring, creating a stable and fast backhaul link.

Does Powerline Networking Affect Speed or Latency?

Powerline networking, in general, offers reliable speeds, but they can be affected by the quality of your home’s electrical wiring and any interference from other devices plugged into the same circuit. The Deco P7’s powerline technology supports speeds of up to 600 Mbps, which is more than adequate for most tasks like streaming, browsing, and online gaming.

In some cases, powerline networking may introduce slightly higher latency compared to wired Ethernet connections, but the difference is often negligible for everyday use. In contrast, the powerline feature greatly enhances stability in homes where wireless signals between nodes might be weak due to thick walls or long distances.

Use Cases for the TP Link Deco P7

The TP Link Deco P7 is a versatile solution, but it truly shines in the following situations:

1. Homes with Thick Walls: If your home has thick concrete or brick walls that hinder Wi-Fi signals, the P7’s powerline feature can help ensure a strong connection between units.
2. Multi-Floor Homes: In multi-story houses, where placing Wi-Fi nodes on different floors might result in poor signal strength, the powerline backhaul ensures that the nodes remain connected through your electrical wiring.
3. Large Homes: The P7 can cover homes of up to 6,000 sq. ft. with three units, making it ideal for large spaces.
4. Homes with Interference Issues: If your home has lots of wireless interference (from other devices or neighboring Wi-Fi networks), the P7’s powerline backhaul will help maintain a strong connection between nodes.

Considerations for Buyers

While the TP Link Deco P7 offers many advantages, there are some things to keep in mind if you’re considering purchasing this unit:

• Wi-Fi 5 Technology: The Deco P7 supports Wi-Fi 5 (802.11ac), which is an older standard compared to Wi-Fi 6. Wi-Fi 6 offers better performance, especially in crowded environments with lots of devices. If you have many modern devices that support Wi-Fi 6, you may want to consider opting for a newer unit.
• Powerline Limitations: Powerline performance can be impacted by the quality of your home’s electrical wiring. In newer homes with good wiring, the system will perform well, but older homes with outdated wiring may not see as much benefit from the powerline backhaul.
• Speeds for Modern Devices: While the Deco P7 offers up to 867 Mbps on the 5GHz band, newer Wi-Fi 6 units offer much faster speeds, with improved efficiency for multiple devices. If speed is a top priority, a Wi-Fi 6 option may be more appealing.

Pros of Choosing a Wi-Fi 6 Option

Probably the only noticeable downside of this unit is the fact that it is still on Wi-Fi 5 technology. It might be more beneficial to rather look for a Wi-Fi 6 or later model if you are buying this unit new now. If you’re considering a Wi-Fi 6 unit instead of the Deco P7, here are a few benefits:

• Faster Speeds: Wi-Fi 6 provides significantly higher speeds than Wi-Fi 5, particularly in busy environments.
• Better Device Handling: Wi-Fi 6 is designed to handle more devices simultaneously, making it ideal for smart homes with many connected gadgets.
• Improved Range and Efficiency: With technologies like OFDMA and MU-MIMO, Wi-Fi 6 networks are more efficient, reducing congestion and improving range.
• Future-Proofing: Choosing a Wi-Fi 6 unit ensures you’re investing in the latest technology, which will be relevant for a longer time compared to a Wi-Fi 5 system.

Conclusion

The TP Link Deco P7 offers a unique blend of mesh Wi-Fi and powerline networking, making it ideal for homes with thick walls or large spaces. Its powerline backhaul ensures reliable communication between units, even in challenging environments. However, as a Wi-Fi 5 system, it may not be the best choice for those looking for the latest speeds and efficiency of Wi-Fi 6. For users prioritizing strong coverage in complex home layouts, the Deco P7 remains a solid and affordable option, though those looking for more speed and future-proofing should consider Wi-Fi 6 alternatives.
