TVU Nano Router (5G) Model RD300 Setup and User Guide


Product overview

TVU Nano Router 5G is the new generation of nano router with three built-in 5G cellular modems and an internal battery in a 1U chassis. Its small size is perfect for field staff, broadcast trucks, and mobile receiver transmission solutions. In addition, the 5G router provides high-performance, highly reliable network aggregation transmission supported by cutting-edge aggregating technology.

The Nano router has a two Gbps-Ethernet interface, 1 USB interface, and a WiFi module. It can be connected to satellite, microwave, WiFi, and Ethernet, providing customers with a stable Internet access capability of up to 200 Mbps bandwidth.

The TVU 5G Nano Router adopts Inverse StatMux Plus (IS+) technology, which can realize reliable network transmission even in the most challenging transmission environment (such as fast-moving vehicles). As a result, when a single network connection is interrupted or bandwidth fluctuates, the overall
network bandwidth and quality will not be affected, and the video stream and various network applications running on the router will not be interrupted.


Features overview

The TVU Nano Router has a small, lightweight, and robust hardware design and functions to fit the needs of any live broadcaster. The built-in battery allows field staff to transport the router on location and is easily installed into a standard rack inside a vehicle or control room.

The TVU Nano Router supports simultaneous connections to multiple networks, including mobile cellular networks, satellite, microwave, WiFi, and Ethernet. The TVU Nano Router runs on the TVU platform and includes the following functions and features:

  • Simple Worry-Free Operation: TVU pioneered one-button operation in portable live video streaming transmitters, and TVU Nano Router carries that tradition. TVU Nano Router can be configured in the field and boots up in less than 35 seconds with a push of a button.
  • Small Form Factor, Big Features: TVU Nano Router’s industrial design and compact metal enclosure provides high reliability. Its ultra-portable weight and size make it the perfect device for on-the-go and anywhere live video broadcasts.
  • Inverse StatMux Plus: TVU Nano Router features proprietary video transmission technology called Inverse StatMux Plus (IS+). TVU’s patented algorithm allows for uninterrupted, reliable transmissions by aggregating multiple connection links, including cellular, WiFi, Ethernet, satellite, and microwave.
  • Power source: The TVU Nano Router has a single, rechargeable Li-ion internal battery and a 2A 12V DC power adapter. The internal battery run time supports 3.5 hours of working and 5.5 hours of standby power.
  • External Hotspot antennas: The TVU Nano Router can be configured using the TVU Router Hotspot antennas and the Web user interface. The TVU Router configuration interface can be accessed using a standard web browser.
  • LAN Support: Ethernet (RJ-45, 2 GbE connections) and WiFi Hotspot (WAP, 802.1 1b/g/n/ac, 2.4 GHz / 5 GHz.
  • Supported WAN connections: Simultaneously aggregates up to 6 data connections, including WiFi and Ethernet. System supports 3 micro sims (3ff) cellular 3G/4G/5G LTE modems, 2.4 GHz / 5 GHz WiFi, WiMax, Ethernet, Microwave and KaBand, KuBand, Mesh, and BGAN satellite connections.
  • High-speed Internet access: Multiple available links can be aggregated, including 3 built-in 4G/5G modules, 1 external 2.0 USB module, 1 network cable, and 1 WiFi.

Typical applications – P2P function management

This section describes how the P2P function configures interconnection between devices and routers using the same aggregation gateway.

The following shows two typical application scenario examples:
Scenario 1: P2P interconnection between the device connected to the Router and under the aggregation gateway server.

P2P scenario 1

Client A configures the Router:

  • 192.168.4.*/24 (keep consistent with advanced settings and LAN settings)
  • Open P2P (configure the IP Range parameters and restart the router process without restarting the entire machine)

Client B configures the aggregation gateway server:

  • 192.168.5.*/24
  • Open P2P (configure the IP Range parameters and restart the router process without restarting the entire machine)

Scenario 2: P2P interconnection between devices connected to 2 routers under the same aggregation gateway server.

P2P scenario 2

Client A configures the Router:

  • 192.168.4.*/24
  • Open P2P (configure IP range parameters and restart the router process without restarting the entire machine)

Client B configures the Router:

  • 192.168.5.*/24
  • Open P2P (configure IP range parameters and restart the router process without restarting the entire machine)

P2P Configuration interface

To enter the P2P configuration interface, complete the following steps:

  1. Click the Advanced Settings tab and select P2P Settings. The P2P Support window opens. The P2P function is closed by default.
P2P support window
  1. Enter an IP Range in the provided field. If you have set the IP Range before, open it again to verify the range and apply it by clicking Save.
  2. Otherwise, you can enter the IP network segment range where the connected device is located. It supports the two input methods of “IP/mask” and specific IP range as shown in the following figure. Add a “,” to separate the different IP ranges.
  3. To enable P2P, move the slider to the right until it turns blue. Then, click Save to save the settings.
P2P support window enabled

Note: The IPs of the devices at both ends cannot be exactly the same. Enabling/disabling/modifying P2P settings will interrupt the network for about 2 seconds.

NAT/No NAT server switching support

When the router server is installed, it is configured by the TVU support team.

Horizontal expansion and remote backup server support

When the Auto mode is selected on the aggregation gateway server setting page, the aggregation gateway that cooperates with the router will automatically and intelligently select and allocate the cloud scheduling service. At this time, the aggregation service can automatically support expansion and remote backup.

Router server - Auto mode

Smooth expansion

When the number of router users increases, the aggregation gateway deployed in the cloud can smoothly expand. Then, the newly opened aggregation router is automatically assigned to the newly opened aggregation gateway.

Remote backup

If the gateway device serving the router fails, it will automatically switch to other available aggregation gateways to ensure the uninterrupted operation of aggregation services.

Turning the Nano Off

After use, complete the following steps to turn the Nano Off:

  1. To turn the nano router off when the nano is running in normal mode, press and hold the power button for 5 seconds, then release the button. The device shuts down normally when the indicator light is no longer illuminated.
  2. The device may experience an unknown status when running, such as being unable to view the Web interface or the battery having too much capacity. If this occurs, press and hold the power button for 10 seconds to shut down the nano router immediately.
