802.11ax Powerful Performance

1.The 5GHz band of 802.11ax is 1.37 times faster than 802.11ac.
2.The 2.4GHz band of 802.11ax is 1.91 times faster than 802.11n.
3. In DBDC (dual-band, dual-concurrent) mode, 802.11ax with both 5GHz+2.4GHz is 1.52 times faster than the combination of 5GHz 802.11ac + 2.4GHz 802.11n. 

OFDMA

 
OFDMA is applied in Wi-Fi 6 (IEEE 802.11ax). It is a user access technology that allows spectrum to be simultaneously allocated to multiple users or devices, enabling the transmission of multiple data streams on the same frequency band, thereby enhancing network efficiency. 

  It can also be adjusted according to demand or priority, achieving more flexible network resource management. By dividing the spectrum into small subcarriers, OFDMA can also reduce interference between adjacent users, making the signal more reliable and stable. This is one of the latest key technologies in Wi-Fi 6.

 

Downlink & Uplink MU-MIMO

  In 802.11ac, basic Downlink MU-MIMO was introduced, allowing wireless access points (such as routers) to simultaneously transmit data to multiple client devices.

  However, in Wi-Fi 6, MU-MIMO technology has been further developed to communicate simultaneously with multiple devices in both the Downlink and Uplink directions.

  This means that whether sending data from the access point to devices or from devices to the access point, multiple device data streams can be processed simultaneously.

  This enables faster and more reliable wireless connections, while also improving network throughput and efficiency.

BSS Coloring

  BSS Coloring is a feature introduced in the 802.11ax Wi-Fi standard, which helps reduce interference from neighboring Access Points (APs) and improves coexistence between multiple APs.

  The basic idea behind BSS Coloring is that each BSS or AP is assigned a unique color, which is added to the preamble of each transmitted data packet. When a client device receives a packet, it can check the color of the received preamble and use this information to differentiate signals from different APs.

  BSS Coloring helps prevent unnecessary retransmissions and conflicts caused by neighboring networks, thereby improving overall network efficiency and potentially extending the available range of IoT devices.

802.11r Fast Roaming Technology
 

•IEEE 802.11r (Fast Basic Service Set Transition) is a wireless network standard aimed at achieving fast roaming without the need for complete re-authentication.
•Fast Roaming: 802.11r allows mobile devices to transition faster from one access point (AP) to another AP without the need for complete re-authentication and connection processes.
•Seamless Switching: By reducing the need for re-authentication, 802.11r achieves a seamless roaming experience. Users can naturally switch to access points with stronger signals or better quality while moving, without the need to manually reconnect to the network or input credentials again.
•Pre-authentication: Before actual movement occurs, mobile devices can pre-authenticate to potential target APs, enabling quick switching to the AP when needed, further reducing connection interruption time during the switching process.

Frequently Asked Questions (FAQ)

What is the WR322GR-WLAN6-LTE-3D used for?

The WR322GR-WLAN6-LTE-3D is an industrial rugged router combining Dual SIM Dual Active LTE with Wi-Fi 6 (IEEE 802.11ax) for mission-critical connectivity in ITS, railway trackside monitoring, smart city infrastructure, industrial automation, and SCADA networks. It provides secure serial data bridging, cloud IoT integration, and VPN communication for industrial IoT deployments.

What wireless standards does the WR322GR-WLAN6-LTE-3D support?

The router supports IEEE 802.11ax (Wi-Fi 6) with full backward compatibility for 802.11ac/n/g/b/a. It operates on Dual Band Dual Concurrent (DBDC) 2.4 GHz and 5 GHz frequencies simultaneously, delivering up to 1,774 Mbps combined PHY rate (1,200 Mbps on 5 GHz + 574 Mbps on 2.4 GHz). LTE Cat.4 connectivity provides up to 150 Mbps downlink and 50 Mbps uplink with 2×2 MIMO.

Does the WR322GR-WLAN6-LTE-3D support Dual SIM failover?

Yes. The router is equipped with dual Nano SIM slots and supports Dual SIM Dual Active (DSDA) operation, enabling simultaneous use of two SIM cards with zero-interruption carrier switching. LTE-to-Ethernet WAN redundancy and LTE-to-WLAN auto-offload further ensure uninterrupted connectivity even when one link fails.

What is the difference between Dual SIM failover and Dual SIM Dual Active?

Dual SIM failover switches to a backup SIM only when the primary connection fails. Dual SIM Dual Active (DSDA) allows two SIM cards to operate simultaneously on two active cellular connections, providing higher network resilience and non-stop carrier switching with no gap in connectivity for mission-critical industrial applications.

What VPN and security features are supported?

The router supports IPSec (AES-256), OpenVPN (server/client, multipoint VPN), L2TP with PPP/PAP/CHAP, and GRE tunnel for encrypted remote connectivity. A stateful inspection firewall provides inbound/outbound traffic control with IP/Port filtering and MAC ACL. Additional security layers include IEEE 802.1X/RADIUS authentication, TACACS+ multi-user management, HTTPS/SSH secure login, and TLS 1.2.

What serial communication interfaces does the WR322GR-WLAN6-LTE-3D provide?

The device includes two RS232/422/485 DB9 serial ports supporting full RS232, RS422, and RS485 functions. Serial data can be tunneled over LTE, Wi-Fi, or Ethernet using TCP Server, TCP Client, or UDP modes. Modbus RTU protocol is supported natively, enabling seamless integration with industrial field devices and PLCs.

Does the WR322GR-WLAN6-LTE-3D support cloud and IoT platform integration?

Yes. The router includes built-in agents for Amazon AWS and Microsoft Azure, enabling direct connection to public cloud IoT services. MQTTS and CoAP protocol support provides flexible messaging for private and public cloud environments. The embedded RESTful API allows integration with third-party IoT platforms and custom management systems.

Can the WR322GR-WLAN6-LTE-3D be managed remotely?

Yes. The WR322GR-WLAN6-LTE-3D supports over-the-air remote management via WoMaster ThingsMaster OTA. Administrators can perform group-based firmware upgrades, configuration reloads, and device reboots remotely from any location using mobile or fixed networks. ThingsMaster OTA also provides a real-time map displaying device status, LTE signal strength, and GPS location, and can be deployed on private servers or QNAP NAS.

What routing protocols and WAN redundancy options are supported?

The router supports dynamic routing via RIPv2, OSPFv2, and VRRPv2 for high-availability network deployments. Static unicast routing is also available. WAN redundancy options include cellular-to-Ethernet WAN failover, dual SIM backup switching, and LTE-to-WLAN auto-offload. RSTP provides additional loop protection in Ethernet network segments.

What GPS and GNSS capabilities does the router support?

On models equipped with GPS, the WR322GR-WLAN6-LTE-3D supports GPS, GLONASS, BeiDou, and Galileo satellite systems. Cold start acquisition takes approximately 18 seconds, with hot start under 2 seconds. Positioning accuracy is under 1.5 meters. Location data can be displayed on Google Maps or Baidu Maps via the ThingsMaster OTA platform for real-time asset tracking.

Is the WR322GR-WLAN6-LTE-3D suitable for harsh industrial environments?

Yes. The WR322GR-WLAN6-LTE-3D is rated for operation from -40°C to 70°C, making it suitable for harsh outdoor and industrial environments. It holds CE Marking and complies with EN50121-4 for railway trackside EMC, IEC61000-6-2 (heavy industrial immunity), and IEC61000-6-4 (heavy industrial emissions), qualifying it for railway, ITS, oil and gas, and outdoor smart city deployments.

What power input and mounting options are available?

The WR322GR-WLAN6-LTE-3D accepts a wide-range DC power input of 9–48 VDC (nominal 24 VDC) via a 6-pin removable terminal block connector, which also provides a 2-pin dry relay output (1A/24VDC) for alarm signaling. The unit ships with a DIN rail clip for standard DIN rail mounting. A USB port supports field-based configuration and firmware updates without network connectivity.
