The wireless data modem is then used to communicate with external data servers.

Description:
TECHNICAL FIELD 
       [0001]    The invention generally relates to communication systems and more particularly to mobile data access. 
       BACKGROUND ART 
       [0002]    Various individuals have provided means to enhance radio system and more specifically first responder safety and efficiency. The industry is moving to combine the advantages of 3G and LTE technologies into a new generation of communication device. 
       SUMMARY OF INVENTION 
     Technical Problem 
       [0003]    Radio system users require the ability to transmit and receive data in addition to voice. Whether the data is location, sensor readings, images, or documents. The investment in radios systems has already been made; with this invention the investment in existing radio systems is protected as any radio system is upgradeable. 
       Solution to Problem 
       [0004]    Operationally it is impractical to use a separate land mobile radio and the data side of a smart phone simultaneously without a device that provides adequate volume for the smart phone and ergonomics to utilize both simultaneously with adequate control so that no audio is lost from either source. By combining the audio source and destination from a radio system via the speaker microphone, the radio audio can be effectively treated as data. That data can be stored, sent to and received from servers over the cellular broadband network and can be combined with data sent to and received from servers. 
       Advantageous Effects of Invention 
       [0005]    Most public safety agencies can effectively jump a generation in radio technology by acquiring new speaker microphones for their existing radios.

     DESCRIPTION OF EMBODIMENTS 
       [0008]    The present invention  104  can be provided with varying cables to connect to the different models of radio. It does not depend on the radio being a portable radio  103  as shown in the drawings but will work just as well with in-vehicle mobile radios. The device may also be deployed as a wireless device where in the radio is connected via Bluetooth  210 . 
         [0009]    This device addresses the identified problems by providing wireless broadband access, integrated into the first responder&#39;s radio system. By placing the broadband modem and processor in the speaker/microphone it has access to the radio audio and thus can be seamlessly integrated into virtually any radio system. The wireless broadband  102  will support access to various data servers  106 : a VOIP server that can provide alternate (additional) access to audio, a data server that can record sensor readings coming from the responder or even from his environment (automobile, fire temp, gas or radiation sensors), and provide data to/from the existing police, fire, or medical data systems . The device will support voice commands in addition to control buttons and will include text to voice from received data (auto license plate check; responding with Owner name and address). The device contains an encryption chip to allow the users to choose to utilize encrypted data between the device and the servers. 
         [0010]    With the device a responder can talk to his team members over the radio while monitoring command over the VOIP broadband connection. Conversely a Fire Sector Lead can establish a full duplex (hands free) connection over broadband  104 / 101  to his team while communicating with Fire Command on his radio  103 . 
         [0011]    Because the device has a personal network (pnet)  211 ; sensors attached to the SWAT or Fire team members, can communicate to the device for re-transmitting the vital statistics: body temperature, pulse, heart (EKG), and air remaining in tank, to command throughout an operation. 
         [0012]    Integration of the wireless broadband device into the radio system supplements the coverage area of a public safety radio system  100  with the coverage area of the 3G/4G  101  provider. When both the radio and the VOIP connections are carrying the same audio the user can pick whichever audio has the best quality. 
         [0013]    As indicated above the device allows the user to access multiple audio paths simultaneously over a single device. The user can select audio source(s) and destination(s). Input audio can be from a broad band VOIP source or the LMR. Audio Output can be directed to either device or both as long as they are not on the same radio frequency. 
         [0014]    When the user is monitoring multiple talk paths it is inevitable that audio collisions will occur. All received audio is stored on a micro flash  213  and the user is notified that audio is waiting via a light on the display  209 . Upon demand a user can replay received audio. 
         [0015]    The device provides optional on demand hands free full duplex audio capability for emergency situations. Depressing the emergency button  205  puts the user into a hands free mode in which all voice audio is transmitted as data to an audio server. This allows support/backup personnel to monitor the situation while communicating with each other on an alternate talk path (the radio). 
         [0016]    The device provides the ability to track location. The device periodically communicates the GPS coordinates to a data server. Location reporting can be initiated by Voice command or by a remote command sent via the data server. 
         [0017]    The device optionally links (via usb  214 , blue tooth  211 , or WiFi  212 ) to smart phones, tablets, notebooks, laptops, . . .  105  in order to provide data for remote device installed applications or for direct display: html from the processor. 
         [0018]    The device optionally utilizes available wireless network  212  connectivity to increase throughput and minimize connection cost. 
         [0019]    The device optionally provides broadband access to WiFi  212  enabled devices. 
         [0020]    The device improves interoperability: responders are now sharing a common frequency (the 3G/4G providers radio frequency) regardless of the frequency utilized by the LMR. All responders with a turtle can be connected to the talk path appropriate to the responder&#39;s assignment. As a highway patrolman travels the highway his device can access the contact information for the local sheriff and/or local municipal police so that upon demand: “Command: Contact Local Police” the system can connect the patrolman to the VOIP device for the local police department dispatch. 
         [0021]    The device improves response management of an incident by providing multiple talk paths regardless of the number of licensed frequencies held by the responding agencies and responsible jurisdictions. 
         [0022]    The device enables the responder in the field to select the audio to monitor as well as the talk path to use. 
         [0023]    The device enables hands free full duplex audio between (Fire or SWAT) team members while providing Fire/Police Command access over the LMR. 
         [0024]    Thus the device effectively extends the life of existing radio systems by allowing any radio system to jump directly to LTE without significant investment. 
         [0025]    A responder using the embedded camera can photograph a scene, evidence, or even record video to be transmitted to command. 
       INDUSTRIAL APPLICABILITY 
       [0026]    Utility companies pass maintenance documents via the broadband interface to the field personnel on demand based on the problem identied once the personnel is on site. These documents can be converted text to speach or transmitted for display to a tablet or pc. 
         [0027]    Medical personnel can pass patient monitor readings and injury images to trauma personnel while enroute to the trauma center. 
         [0028]    Law enforcement can retrieve wants and warrents, drivers license, auto license, and other information even when they are away from the MDT in their vehicle. 
         [0029]    Fire personnel can attach sensors that are monitored by command to insure the safety of personnel. The procedures for hazardous material identification can be accessed and followed interactivily.
