Mobile Cellular Amplifiers. Mobile 3G/ 4G Routers & Antennas

NOTES:

> Need an amplifier that is capable of handling mobility (wireless data communications systems degraded by a phenomenon called Doppler frequency spread in a moving vehicle).
> Need an omnidirectional antenna since the direction of maximum received signal strength varies depending on where the vehicle
> Typically powered by a DC/DC converter from the car battery
> Wireless systems components should be capable of handling temperature gradients and vibration dynamics of a moving vehicle

Brief Description

 

Remote Mobile Communication Solution #3

A generic example of a communication trailer for example for a mobile office. Shown here with cellular to PSTN phone/ fax system (Fixed Wireless Terminal) and Cellular 3G/4G router. Uses 2 WAN's for data to provide seamless failover in the event that one data network fails. Also provides for a Cellular bi-directional amplifier to ensure maximum speed of cellular 3G data modem.

Remote Mobile Communication Solution #1

A generic example of a communication trailer for example for emergency management. Shown here with the option to extend wireless Internet coverage for 2 miles using a portable Point-to-Point Microwave data link. Contact us for the entire solution and for your custom design based on specific constraints and target specifications.

Remote Mobile Communication Solution #2

A generic example of a communication trailer for example for emergency management. Shown here with the aggregation of 5 cellular 3G and WiMax 4G data modems for increased performance and redundancy. Design includes:

  • [Page1] Isolation of 3G Cellular & 4G WiMax RF paths with cross-band coupler/ diplexer for independent boosting (and to prevent filtering out of higher frequency Wimax band by 3G cellular bi-directional amplifiers).
  • [Page2] Splitting 2.4GHz WiFi RF path into two channels one goes to outdoor MIMO antennas and other go-to indoor antennas.

Shown for vehicle use but easily adapted to the building, remote sites, etc. Contact us for the entire solution and for your custom design based on specific constraints and target specifications.
