Doodle Labs, a developer of wireless soluitions for Industrial IoT applications has introduced a family of 4.9 GHz Wireless Broadband Interface Cards that allow System Integrators to rapidly develop wireless routers that provide integrated, wireless WAN or LAN capabilities in the licensed 4.9 GHz band. These routers can provide public safety, homeland security, and transportation organizations with a mobile networking platform that extends the edge of the IP network out to mobile workforce in vehicles, trains, or airplanes. The wireless routers create a network in motion, enabling multiple devices in and around a vehicle to be connected to the main network as the vehicle roams between wireless WAN networks. This solution fully supports standards-based Mesh and Mobile IP applications for seamless roaming across different types of wireless networks and technologies.
Designed in the compact miniPCI-Express form factor, the 4.9 GHz Broadband transceivers provide licensed, secure and fast communication. The 4.9 GHz transceivers are long range, up to 29 dBm RF power, FCC Part 90, IEEE 802.11y and 802.11n compliant radio Subsystems. They are developed specifically for applications needing very high throughput over long range in the rugged/outdoor environments.
4.9 GHz Public Safety Band
The FCC in the United States has allocated 50 MHz of licensed bandwidth in the 4.9 GHz frequency band for wireless broadband access for the public safety agencies to support mobile and fixed services. This licensed band enables the public safety organizations to create highly secure wireless IP networks between a remote workforce and headquarters. Improving communication through Broadband/IP applications empowers the remote workforce with information and tools that traditionally were accessible only from within the boundaries of an office building. Non-traditional public safety entities, such as utilities and commercial entities, and the Federal Government may enter into sharing arrangements with eligible traditional public safety entities to use the 4.9 GHz band in support of their missions regarding homeland security and protection of life and property. Many other countries (e.g. Japan and Australia) also have reserved this band for the exclusive use by the Public Safety Agencies.
Target Applications:
The 4.9 GHz band supports a wide variety of wireless broadband applications. The following types of uses have primary status:
- Wireless LANs for incident scene management (ad hoc mobile networks)
- Mesh networks
- Back-hauling for Wi-Fi hotspots
- Voice over IP (VoIP)
- Temporary fixed communications
- Permanent fixed point-to-point/multipoint links that deliver broadband service
- Permanent fixed point-to-point video surveillance
- Permanent fixed point-to-point/multipoint backhaul of broadband traffic originating from 700 MHz public safety broadband networks
The 4.9 GHz MIMO transceivers are available now.
