WiFi Bridge Comparison – Different Gateway Types

Overview

Simpled gateways enable remote control, monitoring, and management of smart locks through the TTLock app and cloud. While all gateways provide core remote features, they differ in connectivity, power supply, network stability, and smart home integration.

This article explains the differences to help customers and staff choose the correct gateway for each installation.

Gateway models explained

TG Gateway (G2) – Wi-Fi Gateway

The G2 is a wireless gateway designed for simple residential setups.

• Connects to the router via Wi-Fi (2.4 GHz)
• Powered by Type-C USB (DC 5V / 500mA) from a wall outlet
• Compact (approx. 70 × 70 × 26 mm, ABS material)
• Supports core TTLock features such as:
  • Remote unlocking
  • E-key sharing
  • Lock status monitoring
• Uses IEEE 802.11 b/g/n standards

Best for: Homes with stable Wi-Fi where flexible placement is needed.
Limitations: Performance depends on Wi-Fi stability and requires constant outlet power.

Wired Gateway (G3) – Ethernet Gateway

The G3 uses a wired Ethernet connection for improved reliability.

• Connects to the router via RJ45 Ethernet (10M, IEEE 802.3)
• Powered by Type-C USB (DC 5V / 500mA)
• Same size and material as G2 (70 × 70 × 26 mm, ABS)
• Provides the same TTLock app features as G2
• No Wi-Fi support

Best for: Locations with unreliable Wi-Fi or where stable connectivity is critical.

Matter Gateway (G6) – Smart Home Integration Gateway

The G6 adds Matter protocol support for advanced smart home environments.

• Wi-Fi connectivity: 4 GHz and 5 GHz
• Powered by Type-C USB (DC 5V / 500mA)
• Slightly larger housing (75 × 75 × 24 mm)
• Supports Matter, enabling integration with:
  • Apple HomeKit
  • Google Home
  • Amazon Alexa
  • Samsung SmartThings
• Enables advanced automation, multi-platform control, and time calibration

Best for: Mixed smart home ecosystems requiring cross-platform compatibility.
Key difference: Other gateways are limited to the TTLock ecosystem and basic voice assistant support.

PoE Gateway (G3P) – Power over Ethernet Gateway

The G3P is a professional-grade gateway using PoE for both power and data.

• Connects via RJ45 Ethernet (10/100M)
• Powered through PoE, eliminating the need for a wall outlet.
• Includes Type-C USB backup power (DC 5V / 500mA)
• Same size as G3 (70 × 70 × 26 mm, ABS)
• Ideal for structured cabling environments

Best for: Commercial or professional installations where centralized power and maximum stability are required.
Power flexibility: Can be powered by either PoE link or a standard USB power supply type C wire.

Shared features across all gateways

• AES 128-bit encryption for secure communication
• Indicator lights for status and connectivity
• Maximum operating distance of approximately 5 metres from the lock
• Cloud integration for:
  • Access records
  • Remote sharing
  • Lock management
• Cables and power adapters are not included

Why this matters

Choosing the correct gateway ensures reliable remote access, optimal performance, and compatibility with the customer’s network and smart home setup. Wireless gateways offer flexibility, wired and PoE gateways provide stability, and the Matter gateway enables full ecosystem integration.

Quick summary

• G2: Wi-Fi gateway for simple home use
• G3: Wired Ethernet gateway for stable connectivity
• G6: Matter-enabled gateway for multi-platform smart homes
• G3P: PoE gateway for professional and commercial installations

All gateways deliver the same core TTLock functionality—the right choice depends on network type, power availability, and smart home requirements.
