Built-In 4G+ LTE Cat6 Modem
The main advantage of the Deco X50-4G is its integrated 4G+ modem. Instead of connecting a separate 4G USB modem to a conventional router, users can insert a compatible Nano-SIM directly into the Deco X50-4G.
The LTE Cat6 modem supports theoretical download speeds of up to 300Mbps. Actual mobile broadband performance depends on the SIM operator, signal strength, available spectrum, carrier aggregation, network congestion, service plan, cell-site conditions and other environmental factors. TP-Link specifically notes that actual 4G downlink speeds vary according to network and environmental conditions.
This makes Deco X50-4G suitable for locations where a traditional broadband connection may not be practical, including farms, holiday homes, temporary shops, warehouses, rural properties and other locations with suitable 4G coverage.
AX3000 Wi-Fi 6 Performance
Deco X50-4G uses dual-band Wi-Fi 6 technology with an AX3000 class wireless configuration:

TP-Link specifies that all three ports are WAN/LAN auto-sensing and that only one port can serve as a WAN port at a time.
External 4G Antenna Support
Deco X50-4G includes 2× external 4G antenna interfaces using SMB connectors. The package includes 2× SMB-to-SMA adapters, allowing compatible external LTE antennas to be connected when required.
This can be useful in locations where the router needs to be positioned indoors while an external cellular antenna is installed at a location with better LTE signal conditions. The exact antenna and installation should be selected according to the local cellular network and supported frequency bands.
Supported 4G and 3G Bands
The TP-Link India specification lists the following cellular bands for the current documented hardware:
| Technology |
Supported Bands |
| 4G FDD-LTE |
B1 / B3 / B5 / B7 / B8 / B20 / B28 |
| 4G TDD-LTE |
B38 / B40 / B41 |
| 3G |
DC-HSPA+ / HSPA / UMTS B1 / B5 / B8 |
The listed frequencies include 2100, 1800, 850, 2600, 900, 800 and 700MHz for the FDD bands, and 2600, 2300 and 2500MHz for the TDD bands.
Whole Home Deco Mesh
Deco X50-4G can work with compatible Deco units to create a larger Mesh network. The X50-4G gateway provides the cellular internet connection while additional Deco units can be deployed in other parts of the property.
TP-Link states that Deco X50-4G is compatible with other Deco models for forming a unified Mesh network. This makes it possible to expand coverage without replacing the main 4G gateway.
Seamless Roaming
Compatible Deco units use a unified Wi-Fi network name, allowing supported client devices to move between Deco nodes automatically. TP-Link identifies support for 802.11k/v/r roaming, although client-device compatibility and additional configuration may be required.
TP-Link describes the roaming transition as taking less than 0.3 seconds under its specified conditions. This should be treated as a manufacturer reference rather than a guaranteed roaming time for every client device or network environment.
Adaptive Path Selection and Self-Healing
Adaptive Path Selection allows TP-Link Mesh technology to select an appropriate route and wireless band for connections between compatible Deco units.
Self-Healing can reroute network traffic through available Deco units if a Deco node encounters an issue. These functions are intended to help maintain connectivity in multi-node Mesh deployments.
Up to 2,500ft² Coverage per Unit
TP-Link specifies up to 2,500ft² / 230m² coverage for a 1-pack under its stated conditions. Actual coverage depends on building construction, wall thickness, interference, device location, client capabilities and other environmental factors.
When additional compatible Deco units are added, the Mesh network can provide broader coverage across the property. TP-Link does not specify that the 2,500ft² figure should simply be multiplied by the number of Deco units, so actual multi-unit coverage should be considered deployment-dependent.
Support for 150+ Devices
TP-Link lists Deco X50-4G as supporting connections for over 150 devices under its stated conditions. This capacity makes it suitable for homes and small environments containing smartphones, laptops, smart TVs, IoT devices, cameras and other network clients.
The 150+ figure is a manufacturer reference and does not mean every connected device can simultaneously achieve maximum wireless throughput. Actual performance depends on traffic patterns, client hardware and network conditions.

HomeShield also provides parental-control and QoS functions. TP-Link notes that HomeShield includes a Free Basic Plan, while additional Pro Plan features may require a subscription.
Parental Controls
Deco X50-4G allows users to create profiles and apply internet-access controls to associated devices. Listed functions include age-based content filtering, bedtime schedules, time limits and time rewards.
These controls can be managed through the Deco App, making it possible to apply different internet-access policies to different family members and their connected devices.
QoS and Device Prioritization
Deco X50-4G supports QoS by device and HomeShield QoS functions. Users can prioritize selected devices when multiple clients are sharing the available 4G or wired internet bandwidth.
This can be useful for prioritizing work computers, video calls, streaming devices or other important clients during periods of heavy network activity.
Guest Wi-Fi
The router supports separate guest networks for both wireless bands:
- 1× 5GHz Guest Network
- 1× 2.4GHz Guest Network
This allows visitors to use the internet through a separate guest Wi-Fi configuration instead of the primary wireless network.
WPA3 Wi-Fi Security
Deco X50-4G supports WPA-Personal, WPA2-Personal and WPA3-Personal wireless encryption. WPA3 provides an updated security option for compatible wireless clients while maintaining compatibility with older supported security modes.
IPv4, IPv6, NAT and VLAN Features
