The dual core CPU with 1.6GHz + 256M flash enables the router to multi-task smoothly.

Optional TWCC** (Train Wireless Carriage Coupling) for auto coupling
IPWMR-3204DF supports series supports optional TWCC** (Train Wireless Carriage Coupling) that enables auto wireless coupling to reconnect APs.

Dual concurrent LTE design 4G/3G for load-balancing
With dual LTE module design (2L model), 4 SIM card slots, IPWMR-3204DF can allow auto-swap, failover & failback between multiple service providers for real non-stop connection. With concurrent LTE modules, it can also allocate bandwidth by Load Balancing** with 8 schemes between multiple WANs. With one mobile LTE module (1L model), 2 SIM card slots, IPWMR-3204DF provides redundant link between two service providers. Both GPS and Russian GLONASS systems are supported.

IEEE 802.11ac dual band radio up to 2.6Gbps bandwidth
With IEEE 802.11ac capability, IPWMR-3204DF can operate either 5GHz or 2.4GHz bands, offering the maximum speed of 2.6Gbps bandwidth (1.3Gbps per 1AC). It is also compatible with 802.11g/n that can work with 2.4GHz for longer range transmission. The WiFi 11ac supports AP/BRIDGE/AP Client modes can be diverse for most of wireless application. Working with load-balancing** “Priority” mode, the AP client can enable router to transmit on WiFi with first priority.

Air-teaming** for wireless high-sustainability and aggregated
The innovative Air-teaming** can combines multiple wireless links to achieve both high-sustainability and aggregated bandwidth. High sustainability can keep the network traffic alive even one link is down or severely interfered. Aggregated bandwidth can bind two link channels to provide the maximum throughput.

MIMO technology with 3T3R and SMA type connectors
Lantech IPWMR-3204DF series adapts MIMO technology with smart antenna transmission and reception for 3T3R. With six external detachable omni connectors and optional antennas, IPWMR-3204DF can have better Wi-Fi & LTE/GPS coverage.

802.11r fast roaming **
IPWMR-3204DF support fast roaming ** (optional) in coordination with Lantech Wireless Controller to allow encryption keys to be stored on all of the APs in a network. Client mode supports PMK** Caching and pre-authentication.

Wireless WMM QoS
IPWMR-3204DF supports 802.11e standard which defines a set of Quality of Service for wireless LAN applications as well as WMM (WIFI multimedia)

Advanced security & 16 SSIDs
The security support standards including 64/128bits WEP, WPA/WPA2 PSK (TKIP, AES), 802.1x ensures the best security and active defense against security treads. Lantech IPWMR-3204DF support up to 16 SSIDs, each SSID has its independent security and encryption.

Load Balancing** with 8 mechanisms for multi-WANs (premium license)
IPWMR-3204DF supports Load Balancing** for LTE/WAN connections. There are eight schemes for Load Balancing** function:

Pack Algorithm Description
Standard Fixed Manually route by traffic type through fixed WAN link.
Basic Package Failover Routes connections through preferred WAN link while others stand-by. Sequentially activate another link if preferred link fail occurs. Once failover will not failback until link loss.
Priority Routes connections through preferred WAN link as primary while others follow by. Ex. Wi-Fi  client>LTE>others
Weighted Round-Robin Evenly distribute the traffic over all working WAN links in circular order according to the specified weights.
Custom Route Routing through the selected WAN for each specific traffic, ex: TCP/UDP port number and IP address.
Full Package (incl. basic package) Sticky Session* Binding all connections in an application session to particular WAN link to ensure all connections in the session are routed to the same WAN link , that is suitable for security services like online payment etc.
Smallest Load* Routes connections through the WAN link with highest free bandwidth ratio.
The ratio = 1 – (traffic load / the capability of a WAN link).
The traffic load could be defined by downstream, upstream or total traffic
Fastest* Routes connections through the WAN link with lowest latency time.

2 port serial connection, Modbus gateway
It builds in 2 port serial connection for RS232, RS422, 485 in which RS422/485 has 2.5KV isolation protection. The built-in Modbus gateway can convert Modbus RTU/ASCII to Modbus TCP for device control.

VPN and firewall
Besides traditional VPN peer to peer tunneling, IPWMR-3204DF support latest Multi-Site VPN function that is an efficient way for mesh tunneling. The registration is under cloud service and encrypted by SSH makes the connection easy and safe. It supports Multi-Site VPN, OpenVPN, L2TP over IPsec, IPsec, PPTP**, L2 over GRE , IPGRE, and NAT for various VPN applications. The built-in Layer-4 firewall includes DDoS, IP address filter / Mac address filter / TCP/UDP port number.

DIDO for alarm & email notice; Event log; Remote Web/SMS** control
2 sets of DIDO function can support additional high/low physical contact for designate applications besides Port / Power events, for example, DIDO function can trigger alarm if the router was moved or stolen. In case of events, the IPWMR-3204DF will immediately send email and trap. When the router is at remote area with limited access, Web/SMS** control can help to get router status or remotely reboot by Web/SMS**.

Wide range input voltage from 9V-60VDC (24V model); Built-in 6 port PoE at/af switch with 80W budget
The IPWMR-3204DF is able to work from 9VDC to 60VDC (24V model) for PoE at/af with PoE budget 80W that is particular good for vehicle, rail train, depot etc. application.

Environmental monitoring for inside router info& alerting; Graphic WIFI & LTE signal strength
The built-in environmental monitoring can detect router ambient temperature, voltage, current where can send the syslog, email** and SMS** alert when abnormal.

Ignition Sensing
Ignition sense allows you to delay power off the router with a designated time delay.

Built-in Managed Switch Function
Managed switch function is built-in and provides various L2+ functions for network access deployment. It delivers port management, VLAN, QoS, multicast, redundant ring and security functions.
