     BRIEF DESCRIPTION OF THE DRAWINGS  
     [0019]FIG. 1 illustrates a block diagram of a wireless control system in accordance with a first embodiment of the present invention.  
     [0020]FIG. 2 shows a block diagram of a wireless control system in accordance with a second embodiment of the present invention. 
    
    
     DETAILED DESCRIPTION OF THE INVENTION  
     [0021] With reference to FIG. 1, there is shown a main circuit board/2-way paging device  1 , which is operably connected to a 2-way paging antenna  2 .  
     [0022] Similarly, a satellite modem/satellite communications circuit board  3  is operably connected to a satellite antenna  4 .  
     [0023] There is also provided a global positioning chip set  5 , which is operably connected to a global positioning antenna  6 .  
     [0024] The system also includes a voltage regulation circuit board  7 , which is operably connected to the main circuit board/2-way paging device  1 .  
     [0025] The system also includes a microprocessor board/carrier roam control  8 , which is operably connected to the main circuit board/2-way paging device  1 .  
     [0026] With reference to FIG. 2, there is shown a motherboard  10  including a dataport  11 . Preferably, but not necessarily, the motherboard  10  may comprise a Motorola Creatalink 2XT.  
     [0027] The dataport  11  is connected to a network roam module  12  CDMA, TDMA, GSM, Reflex, satellite, analog, which in turn is operably connected to a plurality of chipsets, such as CDMA  13 , TDMA  14 , GSM  15 , and Analog Cellular  16 .  
     [0028] CDMA (Code Division Multiple Access) is a “spread spectrum” technology, which means that it spreads the information contained in a particular signal of interest over a much greater bandwidth than the original signal. When implemented in a cellular telephone system, CDMA technology offers numerous benefits to the cellular operators and their subscribers. Such benefits include: capacity increases of 8 to 10 times that of an AMPS analog system; improved call quality with better and more consistent sound as compared to an AMPS system; simplified system planning through the use of the same frequency in every sector of every cell; enhanced privacy; improved coverage characteristics, allowing for the possibility of fewer cell sites; increased talk time for portables; and bandwidth on demand.  
     [0029] TDMA (Time Division Multiple Access) is digital transmission technology which allows a number of users to access a single radio-frequency (RF) channel without interference by allocating unique time slots to each user within each channel. The TDMA digital transmission scheme multiplexes three signals over a single channel. The current RDMA standard for cellular divides a single channel into six time slots, with each channel using two slots, providing a 3 to 1 gain in capacity over advanced mobile-phone service (AMPS). Each caller is assigned a specific time slot for transmission.  
     [0030] The wireless industry began to explore converting the existing analog network to digital as a means of improving capacity back in the late 1980&#39;s. In 1989, the Cellular Telecommunications Industry Association (CTIA) chose TDMA over Motorola&#39;s frequency division multiple access (FDMA) (today known as narrowband analog mobile-phone service, NAMPS) narrowband standard as the technology of choice for existing 800 MHz cellular markets and for emerging 1.9 GHz markets. With the growing technology competition applied by Qualcomm in favor of code division multiple access (CDMA) and the realities of the European global system for mobile communications (GSM) standard, the CTIA decided to let carriers make their own technologies selection.  
     [0031] The two major (competing) systems that split the RF are TMDA and CDMA. CDMA is a spread-spectrum technology which allows multiple frequencies to be used simultaneously. CDMA codes every digital pack it sends with a unique key. A CDMA receiver responds only to that key, and can pick out and demodulate the associated signal.  
     [0032] Because of its adoption by the European standard GSM, the Japanese Digital Cellular (JDC), and the North American Digital Cellular (NADC), TDMA and its variants are currently the technology of choice throughout the world. However, over the last few years, a debate has convulsed the wireless community over the respective merits of TDMA and CDMA.  
     [0033] The TDMA system is designed for use in a range of environments and situations, from hand portable use in a downtown office to a mobile user traveling at high speed on the freeway.  
     [0034] Referring again to FIG. 2, it is shown that the dataport  11  of the motherboard  10  is operably connected to a satellite modem  17 , which in turn is operably connected to a satellite antenna  18 . The dataport  11  of the motherboard  10  is also operably connected to network antennas  19 .  
     [0035] The motherboard  10  is also operably connected to a 12-channel upgradable GPS chipset  20 , which in turn is operably connected to a GPS antenna  21 .  
     [0036] The motherboard  10  is also operably connected to an OBD-II/databus communicator module  22 .  
     [0037] On-board diagnostic systems are in most cars and light trucks on the road today. During the 1970&#39;s and the early 1980&#39;s, manufacturers started using electronic means to control engine functions and diagnose engine problems. This was primarily to meet EPA emissions standards. Through the years, on-board diagnostic systems have become more sophisticated. OBD-II. a new standard introduced in the mid 1990&#39;s, provides almost complete engine control and also monitors parts of the chassis, body and accessory devices, as well as the diagnostic control network of the vehicle.  
     [0038] The motherboard  10  is operably connected to an external voltage regulation circuit variable  23  and an external flash memory and microprocessor  24 .  
     [0039] The present invention provides a wireless device and a wireless control system which allows communication, commands, and readings to be sent via telephone, Internet, e-mail, and any text-compatible device or network. The device is capable of sending, receiving and transferring data via a wireless satellite and paging network.  
     [0040] The device can activate circuits via wireless command, and send data upon request showing the status of a pre-programmed device. The device acts as a gateway between the wireless networks and the circuit is programmed to command, read or communicate with.  
     [0041] The device is capable of sending data in any format. The device is able to be pre-programmed to activate circuitry, global positioning coordinates, take specific readings, and which can be programmed and configured. The device can use “over the air” programming to allow configuration of a device utilizing the wireless network to transfer programming data. The device uses existing wireless service providers to access the network.  
     [0042] The wireless device and wireless control system in accordance with the present invention utilizes multiple networks to send and receive data. For example, the device can use the following network types based on availability in any given area: two-way paging; one-way paging; CDMA; GSM; TDMA; satellite, analog; etc.  
     [0043] The device looks for the best way to send data. If the device is out of range of the two-way paging network, but a one-way paging network is available, then the device will receive data through the one-way paging network, but will utilize either CDMA, TDMA, GSM, or analog network to send the data. If none of these networks are available, the satellite network will be used to send and receive data. All networks can support two-way data transfer assuming coverage is provided in that particular area.  
     [0044] One of the main points of using multiple networks is to lower the cost of data transfer, but the satellite network is a true global system. It will work anywhere in the world. There is no loss of coverage, even in the middle of the ocean.  
     [0045] The omnipresence of the satellite footprint and the speed of data transfer enables the provision of multi-media access via Internet connection (e-mail, movies, web access, etc., satellite telephone, and the ability to remotely guide vehicles along the roadway with the ability of redundant data transfer, GPS, and drive-by wire data bus configuration in the next generation of automotive vehicles.  
     [0046] The installation and operation of one particular embodiment of the invention is explained below.  
     [0047] The wireless control module may be easily installed using normal hand tools. The module is simply mounted and wired up. After powering the system up, the unit can then be configured using Over the Air programming, or by the use of a serial port (terminal program such as Hyperterminal or Procomm required). After the initial configuration, no changes are necessary.  
     [0048] Alternatively, the module can be shipped pre-configured if desired, so no configuration would be necessary at the site.  
     [0049] Messages can be sent when an exception (such as a transition from a good value to a bad one) occurs. The format of these messages are customizable, depending upon the type and requirements of the message that needs to be sent. When an exception occurs, messages can be sent to up to 3 locations or addresses (e-mail, fax, pager, host, monitoring station). These locations are fully customizable by the user. There are two types of messaging available with the wireless control module: Terse and Verbose. These types are explained in detail below.  
     [0050] Terse messaging can be used on any input (digital or analog) or output. Terse messaging may use the Aloha packet scheme that only sends 1 byte of information. This messaging scheme is designed to save costs. Terse messaging can be sent to email, pager, fax, monitoring software, or host. Typically, terse messaging would be sent to a host or monitoring station, where in can be deciphered into a meaningful message. The following is an example of a terse message when the Input number 2 changes from a Good state to a Bad state:  
     [0051] Example of terse message: 20.  
     [0052] The first digit in the message above corresponds to the Input Number (2 in this case). The second digit corresponds to a Bad State (0=Bad, 1=Good, 2-9 are customizable). Because a terse message is an Aloha style message, it will automatically be placed in a designated mailbox by the Network Operator.  
     [0053] Verbose messaging can be used to provide a more detailed explanation of what has occurred. Verbose messages are customizable by the user to the user&#39;s specific messaging requirements. Verbose messages may be up to 50 characters in length. Verbose messages can also be sent to up to 3 locations/addresses (pager, fax, email, host, monitoring station). A verbose message is especially useful if sent to a pager or email, because it contains descriptive information about the exception. Up to twenty verbose messages can be programmed into a wireless unit. The following verbose message can be sent when Input 3 changes from a Good state to a Bad state:  
     [0054] Example of a verbose message: Anytown Pump Station #243-Pump 1 Fail.  
     [0055] Each input can also be designated if additional information (such as a Date/Time stamp of occurrence or Current Value). For example, if a Time/Date stamp is utilized on the above verbose message, it would show as follows:  
     [0056] Example of a verbose message: Anytown Pump Station #243-Pump 1 Fail on 3/1/00 11:43 AM.  
     [0057] The above example would then provide the date and time stamp of the occurrence. If the current value was designated, it would show the value as well.  
     [0058] The following events can cause a message to be sent:  
     [0059] 1. Input Exceptions (Digital and Analog Inputs);  
     [0060] 2. Hardware Exceptions (Hard Reset, Power Loss, Power Restore, Watchdog);  
     [0061] 3. Periodic Status (if enabled);  
     [0062] 4) Polled (Query for status, parameters, etc.)  
     [0063] Hardware Exceptions will be generated and sent upon error, as well as logged. Messaging events (other than Hardware exceptions) will only be sent if configured to do so. Events can be logged only and polled at a later date, if desired.  
     [0064] The wireless unit may come with several options (referred to as modules) which provide specialized features not found in the base wireless unit. Specific functionality for individual applications can also be provided.  
     [0065] AT Emulation Module: An option of the wireless module is to provide Hayes AT command set emulations. This will allow the present invention to replace traditional Land Line Phone Modems and provide instant wireless connectivity. The present invention would provide plug and play replacement of existing modem, emulating Hayes handshaking and protocol methods.  
     [0066] Schedule Control Module: The Schedule Control option allows the scheduling of outputs based on a time schedule. This schedule can be done by seconds, minutes, hours, or exact time (i.e., 4:00 p.m. to 6:15 p.m.). Schedules can be a one-time, or repeating (i.e., every day).  
     [0067] Diurnal Schedule Control Module: Diurnal Schedule Control allows the scheduling of outputs based on Dusk and Dawn algorithms. This can be useful for turning on/off lighting, sprinkler systems, or any other device that relies on Dawn/Dusk algorithms.  
     [0068] Historical Monitoring Module: The Historical Monitoring module allows the monitoring of Inputs based on a time period (i.e., every minute, hour, day or other interval) and stores these values. These values can then be sent at a predetermined time, or polled from the unit.  
     [0069] GPS Module: The GPS module add-on provides GPS monitoring capability.
