ERGO R291b — 4G LTE Wi-Fi Router with 4000 mAh Battery, LTE Cat.7, 2×SMA, WAN/LAN

• 4G LTE Cat.7 with Carrier Aggregation support
• Dual-band Wi-Fi AC1200 on 2.4 and 5 GHz
• 2×SMA for an external LTE MIMO antenna
• 1× WAN/LAN + 3× LAN for backup internet and wired devices
• 4000 mAh battery for автономous operation
• Up to 32 connected users

ERGO R291b supports 4G LTE Cat.7 with speeds of up to 300 Mbps download and up to 100 Mbps upload. The router also supports Carrier Aggregation (CA), which means frequency aggregation.

Real-world speed depends not only on the router itself, but also on signal quality, base station load, available frequency bands in your location, whether the operator supports aggregation, and proper router placement.

One of the key advantages of this model is the presence of two SMA connectors for connecting external LTE antennas in MIMO 2×2 configuration.

This is especially useful if:

• the 4G signal indoors is weak
• walls are thick or the roof is metal
• the house is located outside the city
• you want to improve signal stability

The router does not amplify the signal by itself, but it allows you to build a much more effective solution with a properly selected external antenna.

ERGO R291b works in two Wi-Fi bands:

• 2.4 GHz — better range and better wall penetration
• 5 GHz — higher speed and less interference

The router also has 1× WAN/LAN and 3× LAN, so you can connect a PC, TV, set-top box, NVR, cash register, or other equipment by cable.

This is exactly what makes the model more practical than most simple mobile hotspot routers.

The built-in 4000 mAh battery allows the router to work without external power for up to 10 hours. This is important if you need internet during power outages or in places where stable power is not available.

Actual battery life depends on signal quality, traffic load, number of connected devices, and the active Wi-Fi band.
