4.9 GHz Wireless Broadband Interface
Card
Public Safety Band Transceiver Family
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
Doodle Labs’ family of 4.9 GHz Wireless Broadband Interface Cards allow System
Integrators to rapidly develop the wireless routers that provide integrated, wireless WAN or
LAN capabilities in the licensed 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. 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.

FCC Radiation Exposure Statement
The modular can be installed or integrated in mobile or fix devices only. This modular cannot
be installed in any portable device, for example, USB dongle like transmitters is forbidden.
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This transmitter must not be collocated or operating in conjunction with any other
antenna or transmitter.
This modular must be installed and operated with a minimum distance of 20 cm between the
radiator and user body.
If the FCC identification number is not visible when the module is installed inside another
device, then the outside of the device into which the module is installed must also display a
label referring to the enclosed module.
This exterior label can use wording such as the following:
“Contains Transmitter Module FCC ID:2AG87NM-4965-1F Or Contains FCC ID:2AG87NM-4965-1F''
when the module is installed inside another device, the user manual of this device must
contain below warning statements;
1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions:
(1) This device may not cause harmful interference.
(2) This device must accept any interference received, including interference that may cause
undesired operation.
2. Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
The devices must be installed and used in strict accordance with the manufacturer's
instructions as described in the user documentation that comes with the product.
