`
`BACKGROUND OF THE INVENTION
`
`Abbreviations
`
`Cellular Telephone as CT. Mobile Device as MD. Non
`Wireless Device as NWD. Internet Protocolas IP. The typical
`cellular telephone/mobile device (CT/MD) today has a single
`25
`antenna, which is directly connected to a single receiver.
`While spread spectrum techniques often used in the CT/MD
`use a broadband of frequencies, at any specific point in time,
`only a single frequency connected to one receiver is used.
`While spread spectrum techniques greatly increase the reli
`ability and stability of the transmission, signal “fade' and
`communication disconnects are often encountered. Some
`communications systems may rely on two separate systems;
`one at a high frequency and preferably using spread spectrum
`transmissions for clarity and reliability, and another provid
`ing a different set of frequencies, such as lower frequencies.
`The secondary system is used when signal fade is a problem
`in the main system. These are two separate, complementary
`systems, each devoted to Solving a separate, distinguishable
`problem.

`
`It is an object of the present invention to provide wireless
`enhancements to IP based cellular telephones/mobile wire
`less devices (CT/MD). The same enhancements are applied to
`IP based and locally based network switch boxes.
`The typical CT/MD has one transmitter and one receiver
`(TVR), with one antenna. An unfulfilled need exists for mul
`tiple T/R in a CT/MD, providing enhanced capabilities, and
`the multiple T/R capabilities will often be best met with
`multiple antennas. The present invention is possible due to
`advances in the art which allow the necessary components to
`be integrated, with the size shrunk to achieve the package,
`performance, and cost desired. The multiple T/R capability
`allows the single CT/MD to perform tasks in different envi
`ronments—each TVR being specifically designed or config
`ured for that specific purpose.
`Other objects, features and advantages of the present
`invention will become apparent from the following detailed
`description when taken in conjunction with the accompany
`ing drawings.
`
`BRIEF DESCRIPTION OF THE SEVERAL
`VIEWS OF THE DRAWING
`
`The accompanying drawings, being incorporated in and
`forming a part of this specification, illustrate embodiments of
`
`DETAILED DESCRIPTION OF THE INVENTION
`
`Reference will now be made in detail to preferred embodi
`ments of the invention, with examples illustrated in the
`accompanying drawings. The invention is described in con
`junction with the preferred embodiments, however, it will be
`understood that the preferred embodiments are not intended
`to limit the invention. The invention is intended to cover
`alternatives, modifications and equivalents included, now or
`later, within the spirit and scope of the present invention as
`defined by the appended claims.
`In the present invention, one or more antennas and TVR
`units in a CT/MD will provide better tuning and greater
`bandwidth for a given frequency/application. For example,
`consider an embodiment of a cellphone, CB radio, and wire
`less phone, all in a single CT/MD for improving the data rates
`of a wireless device/network:
`It is seen that the data rate of the CTMD is increased.
`Currently the CT/MD data rates are very low and pose a
`severe limitation for high speed wireless data networking.
`14.4 KBPS (kilobits per second) is probably the best reliable
`speed for a wireless network that is commercially available.
`The speed at which RF waves are transmitted from point A to
`point B is a physical property based on the frequency of

`transmission and reception in a given medium Such as air. The
`signal speed is determined by the frequency and the signal
`strength is determined by the power, line of sight, interfer
`ence, etc. In a given assigned frequency band, the data speed
`is fixed but the power may be varied. The rate at which data
`may be transmitted over a wireless network is also deter
`mined by the ability to encode and decode the signal at the
`T/Rends using the electronics and computing power resident
`at each end.
`Data transferred to a CT/MD over a wireless network
`comes in encoded form and must be decoded at the CT/MD
`after the data is received, such as by a receiver. The ability to
`encode and decode the data is a function of the number of
`encoders/decoders available and assigned to the task at the
`CT/MD or at a network switchbox. It will be appreciated that
`while a CT/MD and a network switchbox are very similar in
`many ways, they are completely different functional units,
`with the CT/MD providing personal services and the network
`switchbox providing system services. The ability to encode
`and decode the data is also a function of the speed at which the
`encoder/decoder electronics operate at the T/R ends. Of
`course, each encoder/decoder must be associated with appro
`priate electronics to effect this task when more than one
`encoder/decoder is used.
`FIG. 1A illustrates characteristics of a cellular telephone/
`mobile device (CT/MD) 100 of the prior art as opposed to a
`desired CT/MD of the present invention having multiple
`transmit/receive (T/R) units and multiple antennas. In FIG.
`1A, Cellphone 102, CB Radio 104, and Wireless 106 of the
`prior art all have a single transmit frequency and a single
`receive 15 frequency. In contrast, the CT/MD 108 of FIG. 1B
`of this embodiment of the present invention has three transmit
`frequencies and three receive frequencies.
`FIG. 2 illustrates an embodiment of the present invention
`for a communication system 200 with data being transferred
`from computer 202 to computer 204. In FIG. 2, computer 202
`communicates through a system of T/R units 206, located
`within or in proximity to computer system 202, with com
`puter system 204 through T/R unit 208. T/R 208 may be
`40
`located within computer system 204 or in close proximity to
`computer system 204 to route the data to computer 204 or
`alternatively to a network server 204, as required. The rate at
`which data from system 202 to system 204 is transferred is
`gated by the speed of the transmit and receive units is
`improved by the parallel paths provided by the present inven
`tion. The signal is sampled and may be multiplexed at each
`end, at a rate that assures accuracy.
`FIG. 3 is an embodiment of the prior art showing a com
`puter to computer data path with a single channel300. In FIG.
`50
`3, using a single antenna and a single T/R unit the signal is
`processed through the internal electronics module 308 of the
`CT/MD 302, said module 308, which is shown separate from
`CT/MD 302 for illustrative purposes only but is normally
`included within CT/MD 302. Module 308 contains RF/IF304
`and A/D, D/A converter 306, as well as processor 310,
`memory 312, control electronics 314, and other electronics
`Such as display electronics 316 and special interface circuitry
`318, such as for driving the output 320. It should be clear that
`output 320 can also be an input/output for the CT/MD 302.
`This is also true for a network switch box such as network
`switch box 552 with the functionality of CT/MD 302. The
`module 308 and elements 310 through 318 are included
`within CT/MD 302 or network Switchbox 552. All of these
`components or systems are normally contained within
`CT/MD 302. Since there is only one path, however, it is clear
`that this system does not form an efficient, convenient inter
`
`30
`
`45
`
`55
`
`60
`
`65
`
`4
`face. The transmission data rate is limited by antenna 322 of
`CT/MD 302, which has only one antenna 322.
`The antenna 322 is capable of receiving only a limited
`frequency band due to its design limitations, which are com
`mon to single antennas used for this purpose.
`Adding additional antennas gives the CT/MD (by exten
`sion the same is true for the network switchbox) enhanced
`capabilities to differentiate between various signals or to
`combine multiple paths into a single communication channel.
`As an example, the design considerations for receiving cel
`lular telephone frequencies may be totally different from
`those for streaming video or data signals, and with the present
`invention both can be combined into the CT/MD.
`FIG. 4 illustrates a dual antenna, dual TVR unit in the
`CT/MD of the present invention in a dual band system 400. In
`FIG.4, this scheme with CT/MD 402 transmitting on the dual
`T/R unit 404 allows the internal processor 406 to indepen
`dently process the two incoming signal streams separately
`and optimally, causing the appropriate output to be delivered
`on the desired output port. In FIG. 4 the processor 406 is
`shown as a single processor, however, the processor 406 is not
`limited to only one processor and may contain multiple pro
`cessors. Alternately, the single processor may have multiple
`channels for parallel processing of each data stream to pro
`cess accurately two distinct signals 408 that were more opti
`mally received by two dedicated antennas and two separate
`T/R units contained within the CT/MD to improve perfor
`mance and quality of output. An example is a CT/MD 402
`which is optimized for video and voice.
`Having more than one TVR unit gives a performance edge
`as each signal can be better processed and tuned to the specific
`frequency band of the signal. Thus better quality of output can
`be achieved for each type of signal and application. As an
`example, by having each of the data streams sampled at
`differing clock frequencies the performance can be better
`optimized.
`FIG. 5A illustrates a dual antenna, dual TVR unit 504 in a
`CT/MD 502 interfacing with a dual processor 506 in the
`present invention in a dual band system 500. In FIG. 5A, in
`addition to multiple antennas 508 and multiple TVR units 504
`the figure also shows multiple processors 506 in a process unit
`functional block in a CT/MD. The system may communicate
`through an output or outputs 510. For example, these outputs
`may be fibre optic channel, ethernet, cable, telephone, or
`other. By extension the feature of multiple antennas, multiple
`T/R units and multiple processors is extendable to the net
`work switchbox or network switch boxes that form a local,
`wide area, Virtual private network or connect to the Internet.
`Server C controls the communication protocols in conjunc
`tion with the network switching box or other devices, such as
`CT/MD 502. The multiple processors 506 allow for parallel
`and custom processing of each signal or data stream to
`achieve higher speed and better quality of output. This can
`also be done with a single processor that has the parallelism
`and pipeline capability built in for handling one or more data
`streams simultaneously. Processor 506 is the complete elec
`tronics inclusive of DSP, CPU, memory controller, and other
`elements essential to process various types of signals. These
`can be defined as, for example, either single chip or multichip
`solutions. The processor contained within the CT/MD 502 is
`further capable of delivering the required outputs to a number
`of different ports such as optical, USB, cable and others such
`as 1202 to 1210. The CT/MD 502 is also capable of taking
`different inputs, as well as wireless, for the appropriate pro
`cessing to be done on these signals within the CT/MD502 and
`outputting the desired signal on a designated port or ports.
`Thus the CT/MD 502 has universal connectivity in addition to

`having a wide range of functionality made possible through
`the features of multiple antennas, multiple T/R units 504 and
`processors 506 in this invention. These features may also
`exist in a network switchbox, such as network switchbox
`552.
`FIG. 5B illustrates a wide band network switchbox system
`550 that is capable of operating in a number of network
`environments sequentially or simultaneously. The network
`Switch box is configured with multiple processors, multiple
`antennas and multiple T/R units that can be multiplexed to
`process incoming and outgoing wireless signals. In addition
`to wireless signals there is a need to process other types of
`input/output signals such as optical, cable, USB etc. to fully
`interface with other types of devices and networks. The net
`work switch box is normally a fixed part of a network,
`whereas the CT/MD is portable. However, the network switch
`box may be portable and may be used in the wireless mode
`only in a wireless network or it may also be connected to one
`or more networks by wired and wireless means to fully lever
`age all the input/output ports.
`In FIG. 5B, network switch box 552 that is limited in
`quality because of the limitations of wireless may fully lever
`age the networks, including fibre optic networks, such as by
`multiple antennas 554 and multiple I/O ports 556. As an
`example, the ability to view streaming video on a network
`switchbox 552 may be limited by the wireless signal quality
`due to the need for compression. This is due to transmissions
`that are inherently impaired in air as opposed to fibre optic
`cable. A prior art network switch box while in the mobile
`mode may receive video of poorer quality. The network
`switchbox 552, when at home or in the office, could be easily
`connected to the optical network directly or through I/O ports
`556, such as by a cradle adapter. In this mode the best data,
`Video or audio quality can be received using the same unit.
`This provides the network switchbox. 552 single unit to have
`universal applications since it can sequentially or simulta
`neously communicate optimally with other systems and net
`works to deliver quality/performance and speed tailored for
`each application.
`The network switchbox. 552 as disclosed above executes
`substantially the same function as the CT/MD 502. However,
`the network switch box 552 operates at a network system
`level capable of coordinating the operations of a number of
`mobile and other devices in one or more networks, while the
`CT/MD 502 performs at a personal level.
`FIG. 6 is an embodiment of the present invention showing
`a wired interface system 600 for wireless or non-wireless
`devices. In FIG. 6, a wireless device, CT/MD 602 with I/O
`ports 610 and CT/MD 612 with the ability to interface
`through a cradle adapter 604 having both wireless and wired
`connections 606 interfacing with multiple input/output (I/O)
`ports 608 is shown. One, all, or some of the connections may
`be used simultaneously or sequentially for combining mul
`tiple data paths into a single path. Whether to combine all the
`paths into a single data channel or use separate data channels
`for simultaneous operations will be based on the needs of the
`application. Examples of inputs/outputs are, for example,
`standard telephone, coaxial cable, Ethernet, twisted pair,
`wireless, optical, and USB. In addition to the multiple I/O
`ports 610 shown on the CT/MD 602 and the ports 608 shown
`for connecting the CT/MD 612 to cradle adapter 604, the
`present invention anticipates a universal port and a universal
`connector. By having the signal path selection done by user
`defined menu driven software and multiplexing the signals
`onto a universal input/output port as opposed to the multiple
`ports 608, 610 or wired connections 606, the desired signals
`are delivered to the universal port.

`Note that the cradle adapter 604 connection also allows I/O
`contacts 608 between a non-wireless device (NWD) 613 and
`a wireless cradle adapter 604 or similar wireless enabling
`attachment. The enabling attachment can make any non-wire
`less device (NWD) unit 613 wireless enabled while being
`plugged into the cradle adapter 604, as shown for CT/MD
`612, to access a number of wired, optical or wireless commu
`nication paths through the ports 608. The cradle adapter itself
`may have multiple antennas, multiple TVR units and multiple
`processors built-in to deliver full functionality. The cradle
`adapter 604 may also accommodate multiple wired or wire
`less devices to be plugged in at the same time. The cradle
`adapter may also contain power ports for the individual
`devices in addition to the I/O ports. The cradle adapter 604
`may be a passive pass through connection enabling device or
`may have internal electronic Smarts to perform certain server
`functions to control data traffic. Alternately, a Server C
`located on a LAN, WAN or the Internet can be the control
`vehicle.
`FIG. 7 is an embodiment of the present invention showing
`a CT/MD 702 having multiple TVR units internally and with
`multiple antennas 710 in a communication system 700 con
`necting to a Server C 706 through a wireless connection 704.
`Server C 706 then communicates with a network such as the
`Internet or other path to data such as a local WAN/LAN line,
`etc., through connection 708. The multiple T/R units and
`antennas 710 allow multiple simultaneous communication
`paths over connection 704 between the CT/MD and the
`Server C Such that the communication rate is increased.
`FIG. 8 is an embodiment of the present invention illustrat
`ing the connection of multiple wireless signals to an optical
`network for connection to a wide area network (WAN) or
`local area network (LAN) or to the Internet. In FIG. 8, a
`CT/MD 802 communicates through internal electronic inter
`faces, such as an RF/IF module 804 and an AD/DA unit 806
`in a T/R block 808 with a processor 810. Processor 810 then
`provides an electrical signal generated by the T/R block 808
`and processed by processor 810 to an optical converter (OC)
`812. OC 812 then delivers the optical signal to fibre optic
`cable 814 for delivery to, for example, a network such as a
`WAN/LAN or the Internet.
`This avoids delay in processing the signal and improves
`quality/performance. Similar conversions can be done by the
`processor for other input/output protocols or systems such as
`universal serial bus (USB) or Ethernet either locally or in
`conjunction with a server such as Server C 706 to receive/
`deliver input output signals as needed. By extension, the same
`features are possible for the network switch box such as
`network Switchbox 552.
`Some unique features of the present invention, which apply
`to either a CT/MD Such as CT/MD 802 or to a network Switch
`box such as network switchbox. 552, are:
`Multiple antennas for greater signal range and bandwidth.
`Multiple T/R units so that paths or tasks can be paralleled.
`Multiple internal signal processors, or one or more proces
`sors that execute in parallel.
`Multiple built in input/outputs for universal connectivity to
`different network environments.
`Capability to interface wired and wireless devices through
`a cradle adapter to achieve universal connectivity.
`Parallel processing of signals and data streams at a system
`level using hardware and software on a server such as Server
`C 7O6.
`FIG. 9 is an embodiment of the present invention showing
`a multiple processing system 900. In FIG. 9, computer 902

`rates. Having a single channel for T/R with a single antenna or

`a single processor would cause a limitation in data transfer
`rates, so multiple channels 912 are provided. Server C910
`polls the tasks by communicating with computer 902 and
`computer 908, and through computer 902 and computer 908
`control the wireless units 904 and 906, such as CT/MDs or
`wireless boxes, by optimally allocating channels and trans
`fers of the data. Having multiple channels 912 enhances the
`data transfer rate compared to a single channel or communi
`cation path. Server C910 oversees the allocation of data to the
`different channels and keeps the process under control. In
`addition the multiple channels 912 help overcome the RF to
`digital electronic conversion rate problem. The rate at which
`the sampling and conversion takes place is a function of for
`example, the A/D and D/A 806 conversion rates and limita
`tions in the other electronics components such as processor
`810. Consequently having the data partitioned by the Server
`C910 and assigned to multiple channels 912 enables parallel
`processing of the communications, and having parallel pro
`cessing of wireless data streams where the data streams coex
`ist, as in the present invention, increases the data transferrate.
`FIG.10 is an embodiment of the present invention showing
`a data system 1000 with three data streams DS1 1002, DS2
`1004 and DS3 1006. In FIG. 10, three wireless T/R units
`1008, 1010, and 1012 are shown. The three data streams
`1002, 1004, and 1006 are processed by the three T/R units
`1008, 1010 and 1012, converted by converters 1014, 1016,
`and 1018, and presented to processors 1020, 1022, and 1024
`under the control of controller 1026. The data streams may be
`interfaced separately with server C 1030 or combined into
`data stream 1028 and interfaced to Server C 1030. The pro
`cessor or CPU speed is seldom a limiting factor, so the
`improvement in speed by providing multiple data paths is
`fully realized by the present invention. Each subtask being
`processed can be assigned to a separate channel. The rate at
`which the data is acquired, processed and converted is depen
`35
`dent on the type of electronic components. Therefore, com
`ponent limitations can be overcome in a straightforward and
`convenient way by parallel processing. In such cases, the
`processor speed is seldom a limitation, and conversion speed
`of RF to electrical and electrical to RF, becomes the primary
`bottleneck in data transfers for wireless systems. By provid
`ing, for example, a single chip, multichip, or hybrid converter
`for parallel conversions in accordance with the present inven
`tion under the supervision of the Server C910, this bottleneck
`is avoided. Each channel may be sampled and clocked indi
`vidually as necessary to optimally process each data stream
`and combine the individual data packets.
`FIG.11 is an embodiment of the present invention showing
`a data system 1100 with three data streams DS1 1102, DS2
`1104 and DS3 1106. In FIG. 11, three fibre optic channel units
`1108, 1110, and 1112 are shown. The three data streams
`1102, 1104, and 1106 are processed by the three fibre opt
