`ABSTRACT
`(57)
`A method and apparatus in which multiple Internet Protocol
`(IP) based wireless data transmissions are simultaneously
`provided between a wireless device and a server, including
`providing multiple antennas, multiple T/R units, multiple
`processors and multiple I/O ports on the wireless device.
`The method includes receiving multiple IP data packets on
`the I/O ports at substantially the same time, and sending
`multiple data packets from the wireless device to the server,
`whereby the transmission rate between the wireless device
`and the server is increased.

`applications and patents.
`
`BACKGROUND OF THE INVENTION
`
`ABBREVIATIONS: Cellular Telephone as CT. Mobile
`Device as MD. Non-Wireless Device as NWD. Internet
`Protocol as IP. The typical cellular telephone/mobile device
`(CT/MD) today has a single antenna, which is directly
`connected to a single receiver. While spread spectrum tech-
`niques often used in the CT/MD use a broad band 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 reliability and
`stability of the transmission, signal “fade” and communica-
`tion disconnects are often encountered. Some communica-
`tions systems may rely on two separate systems; one at a
`high frequency and preferably using spread spectrum trans-
`missionsfor clarity and reliability, and another providing 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.
`
`SUMMARY OF THE INVENTION
`
`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
`(T/R), with one antenna. An unfulfilled need exists for
`multiple 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
`advancesin 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
`environments—each T/R being specifically designed or con-
`figured 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 accompa-
`nying drawings.

`now orlater, within the spirit and scope of the present
`invention as defined by the appended claims.
`In the present invention, one or more antennas and T/R
`units in a CT/MD will provide better tuning and greater
`bandwidth for a given frequency/application. For example,
`consider an embodiment of a cell phone, CB radio, and
`wireless phone, all ina single CT/MDfor improving the data
`rates of a wireless device/network:
`It is seen that the data rate of the CT/MDis 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.

`to point B is a physical property based on the frequency of
`transmission and reception in a given medium such asair.
`The signal speed is determined by the frequency and the
`signal strength is determined by the power, line of sight,
`interference, etc. In a given assigned frequency band, the
`data speed is fixed but the power may be varied. Therate at
`which data may be transmitted over a wireless network is
`also determined by the ability to encode and decode the
`signal at the T/R ends 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/MDorat a network switch box. It will be appreciated
`that while a CT/MD and a network switch box are very
`similar in many ways, they are completely different func-
`tional units, with the CT/MD providing personal services
`and the network switch box providing system services. The
`ability to encode and decodethe data is also a function ofthe
`speed at which the encoder/decoder electronics operate at
`the T/R ends. Of course, each encoder/decoder must be
`associated with appropriate electronics to effect this task
`when more than one encoder/decoderis used.
`FIG. 1Aillustrates characteristics of a cellular telephone/
`mobile device (CT/MD) 100 of the prior art as opposed to
`a desired CT/MD ofthe 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 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 embodimentof 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
`computer system 204 through T/R unit 208. T/R 208 may be
`located within computer system 204 orin 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
`invention. 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
`computer to computer data path with a single channel 300.
`In FIG. 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 forillustrative purposes only but
`is normally included within CT/MD 302. Module 308 con-
`tains RF/IF 304 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 switch box
`
`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
`
`4
`efficient, convenient interface. 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
`common to single antennas used for this purpose.
`Adding additional antennas gives the CT/MD (by exten-
`sion the sameis true for the network switch box) enhanced
`capabilities to differentiate between various signals or to
`combine multiple paths into a single communication chan-
`nel. As an example, the design considerations for receiving
`cellular 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 T/R unit in the
`CT/MDofthe 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
`independently 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 processors. Alternately, the single proces-
`sor may have multiple channels for parallel processing of
`each data stream to process accurately two distinct signals
`408 that were more optimally received by two dedicated
`antennas and two separate T/R units contained within the
`CT/MDto improve performance and quality of output. An
`example is a CT/MD 402 which is optimized for video and
`voice.
`
`Having more than one T/R 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 applica-
`tion. 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 T/R 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 T/R units 504
`the figure also shows multiple processors 506 in a process
`unit functional block in a CT/MD. The system may com-
`municate 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 network switch box 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 con-
`junction 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 multi-
`chip solutions. The processor contained within the CT/MD
`502 is further capable of delivering the required outputs to
`a numberofdifferent ports such as optical, USB, cable and
`others such as 1202 to 1210. The CT/MD502is also capable
`of taking different
`inputs, as well as wireless,
`for the

`

`appropriate processing to be done on these signals within the
`CT/MD 502 and outputting the desired signal on a desig-
`nated port or ports. Thus the CT/MD 502 has universal
`connectivity in addition to having a wide range of function-
`ality made possible through the features of multiple anten-
`nas, multiple T/R units 504 and processors 506 in this
`invention. These features mayalso exist in a network switch
`box, such as network switch box 552.
`FIG. 5B illustrates a wide band network switch box
`
`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 mul-
`tiplexed 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, USBetc.
`to fully interface with other types of devices and networks.
`The network 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 maybe usedin the
`wireless mode only in a wireless network or it may also be
`connected to one or more networks by wired and wireless
`meansto fully leverage 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
`leverage 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
`switch box 552 maybelimited by the wireless signal quality
`due to the need for compression. This is due to transmissions
`that are inherently impaired in air as opposedto fibre optic
`cable. A prior art network switch box while in the mobile
`mode may receive video of poorer quality. The network
`switch box 552, when at home orin 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 switch box 552 single
`unit to have universal applications since it can sequentially
`or simultaneously communicate optimally with other sys-
`tems and networksto deliver quality/performance and speed
`tailored for each application.
`The network switch box 552 as disclosed above executes
`
`substantially the same function as the CT/MD 502. How-
`ever, 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 net-
`
`works, while the CT/MD 502 performsat a personal level.
`FIG.6 is an embodimentof 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 CI/MD 612 with the ability to interface
`through a cradle adapter 604 having both wireless and wired
`connections 606 interfacing with multiple input/output (1/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 needsofthe
`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/MD602andthe 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 opposedto 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
`J/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-wireless device (NWD) unit 613 wireless enabled while
`being plugged into the cradle adapter 604, as shown for
`CT/MD612, to access a numberof wired, optical or wireless
`communication paths through the ports 608. The cradle
`adapter itself may have multiple antennas, multiple T/R
`units and multiple processors built-in to deliver full func-
`tionality. The cradle adapter 604 may also accommodate
`multiple wired or wireless devices to be plugged in at the
`same time. The cradle adapter may also contain powerports
`for the individual devices in addition to the I/O ports. The
`cradle adapter 604 maybe 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 orthe
`Internet can be the control vehicle.
`FIG.7 is an embodimentofthe present invention showing
`a CT/MD702 having multiple T/R units internally and with
`multiple antennas 710 in a communication system 700
`connecting 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/
`LANline, etc., through connection 708. The multiple T/R
`units and antennas 710 allow multiple simultaneous com-
`munication 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 illus-
`trating 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 elec-
`tronic interfaces, 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/LANorthe Internet.
`
`This avoids delay in processing the signal and improves
`quality/performance. Similar conversions can be done by the
`processor for other intput/output protocols or systems such
`as universal serial bus (USB) or Etherneteither 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 switch box 552.
`Some unique features of the present invention, which
`apply to either a CT/MD such as CT/MD 802orto a network
`switch box such as network switch box 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 pro-
`cessors 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 706.

`FIG. 9 is an embodimentof the present invention showing
`a multiple processing system 900. In FIG. 9, computer 902
`and computer 908 need to exchange data streamsat very fast
`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
`C 910 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
`transfers of the data. Having multiple channels 912 enhances
`the data transfer rate compared to a single channel or
`communication path. Server C 910 oversees the allocation
`of data to the different channels and keeps the process under
`control. In addition the multiple channels 912 help over-
`come 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 conver-
`sion rates and limitations in the other electronics compo-
`nents such as processor 810. Consequently having the data
`partitioned by the Server C 910 and assigned to multiple
`channels 912 enables parallel processing of the communi-
`cations, and having parallel processing of wireless data
`streams where the data streams coexist, as in the present
`invention, increases the data transfer rate.
`FIG. 10 is an embodimentof the present invention show-
`ing 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
`
`10
`
`15
`
`20
`
`25
`
`30
`
`may be interfaced separately with server C 1030 or com-
`bined into data stream 1028 and interfaced to Server C 1030.
`
`35
`
`The processor 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. Therate at
`which the data is acquired, processed and converted is
`dependent on the type of electronic components. Therefore,
`componentlimitations can be overcomein a straightforward
`and convenient way byparallel processing. In such cases,
`the processor speed is seldom a limitation, and conversion
`speed of RFto electrical and electrical to RF, becomes the
`primary bottleneck in data transfers for wireless systems. By
`providing, for example, a single chip, multichip, or hybrid
`converter for parallel conversions in accordance with the
`present invention under the supervision of the Server C 910,
`this bottleneck is avoided. Each channel may be sampled
`and clocked individually as necessary to optimally process
`each data stream and combine the individual data packets.
`FIG. 11 is an embodimentof the present invention show-
`ing 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
