AX3000 Indoor vs AX1800 Outdoor Specs
Speed Rating
Product A carries an AX3000 speed rating, delivering up to 2402 Mbps on the 5 GHz band and 574 Mbps on the 2.4 GHz band. This higher aggregate throughput supports faster data rates for bandwidth-heavy tasks. Product B holds an AX1800 rating, providing 1200 Mbps on the 5 GHz band and 574 Mbps on the 2.4 GHz band. While both use Wi-Fi 6, Product A offers significantly more raw bandwidth capacity. If your priority is maximum theoretical speed for multiple high-demand devices, Product A has the clear advantage in this category.
Coverage Area
Product A is a 3-pack system designed to cover up to 6500 square feet of indoor space. It eliminates dead zones across larger homes by using multiple nodes working together. Product B is a single outdoor extender that adds up to 2200 square feet of coverage. It is intended to extend an existing indoor mesh network rather than serve as a standalone whole-home solution. For total home coverage, Product A provides a much larger footprint. If you need to cover a large house, Product A is the superior choice.
Pack Size
Product A comes as a 3-pack, giving you three units to place throughout your home for seamless mesh networking. This configuration ensures strong signals in every room without requiring additional purchases for basic coverage. Product B is sold as a single 1-pack unit. It is an add-on extender that requires an existing indoor mesh system to function. You cannot build a complete network with Product B alone. For buyers starting from scratch, Product A offers a complete solution. Product B is only suitable if you already own a compatible indoor mesh base.
Build and Placement
Product B features an IP65 weather-resistant design, allowing it to withstand rain, dust, and moisture. It supports pole, wall, or tabletop mounting and can be powered via PoEplus, making it ideal for outdoor patios or yards. Product A is an indoor unit with no weather resistance rating. It lacks outdoor mounting options and PoE support. If you need Wi-Fi outside, Product B is the only viable option. For indoor living spaces, Product A is designed for standard home environments.
Ethernet Ports
Product A includes three Gigabit Ethernet ports on each unit, totaling nine ports across the 3-pack. This allows you to connect wired devices like smart TVs or consoles to any node. It also supports wired Ethernet backhaul for better stability between nodes. Product B does not list specific Ethernet port counts in its key specifications. While it may have ports, the data does not confirm their presence or speed. Product A offers verified wired connectivity options. If you rely on wired connections for low latency, Product A provides clear advantages.

Frequently asked questions
Can I mix AX3000 and AX1800 mesh nodes together?
You can mix nodes from the same ecosystem. TP-Link Deco units support mixed setups. However, the entire network will operate at the speed of the slowest node. An AX1800 extender will limit the overall throughput. Stick to matching speed ratings for optimal performance.
Is AX3000 faster than AX1800 for gaming?
AX3000 offers higher aggregate throughput. It delivers up to 2402 Mbps on the 5 GHz band. This supports faster data rates for bandwidth-heavy tasks. AX1800 provides lower speeds suitable for standard browsing. Gamers benefit from the higher capacity of AX3000 systems.
Do I need an AX3000 system for a small apartment?
AX3000 systems like the Deco X55 cover up to 6,500 square feet. This is often more than a small apartment requires. AX1800 options may suffice for smaller spaces. Choose based on your actual square footage and device count rather than just the speed rating.
Can I use an AX1800 extender with an AX3000 base?
Yes, you can extend an indoor mesh network outdoors. The Deco X20 Outdoor is an AX1800 extender. It adds weather-resistant coverage to your existing network. It does not replace the main indoor system. The network will function, but the outdoor node runs at lower speeds.
What is the main difference between AX3000 and AX1800?
The difference lies in design and coverage capacity. AX3000 provides higher aggregate throughput for large households. AX1800 offers lower speeds but can be specialized for outdoor use. Both use Wi-Fi 6 and support up to 150 devices. Choose AX3000 for wide area indoor coverage.
Does the Deco X55 support wired connections?
The Deco X55 3-Pack includes wired connectivity options. It fits buyers who prioritize wired connections over compact form factors. This allows you to connect devices like smart TVs or consoles directly. Ensure you have Ethernet ports available for these wired backhaul connections.
