In accompanying drawing and description, identical reference represents those assemblies shared for different embodiments or configuration.

Describe in figure 3 according to the one or more embodiment of the present invention be suitable to phone wiring on operation based on wireless OFDM modem 30.OFDM modem 30 is based primarily upon the design as shown in WLAN unit 10 in Fig. 1 and assembly. Contrary with WLAN unit 10, RF signal is not couple to antenna 22, but connects up/down changer 31.Changer 31 is by ISM band Spendable frequency band in the phone wiring that baseband signal is displaced in indoor/office or any other building.Due to North America specifies, it is taken as that spendable frequency band extends to 30MHz about the FCC of radiated electromagnetic emission.So, for occupying The frequency spectrum distribution of 22MHz baseband signal can become chart as in Fig. 4 between 8MHz and 30MHz (center is around 19MHz) Shown in the curve 43 of 40 parts, the figure shows the example various power levels distribution along frequency axis 44.This distribution is considered Use ADSL the signal 42 and POTS signal curve 41 of 100KHz (or 25KHz) to 1.1MHz.ADSL is that asymmetrical digital is used The abbreviation of family line, it uses standard phone line to transmit high-speed data communication in upstream and downstream, uses telephone wire bandwidth It is not used in a part for voice, thus allows to carry out voice communications versus data communications simultaneously.

As a limiting examples, use mid frequency at the channel 10 of 2457MHz (such as Fig. 2 in WLAN unit 30 Shown in middle curve 25), need changer by frequency upper shift or to move down 2457-19=2438MHz, thus create shown in chart 40 Frequency distribution.

In order to avoid carrying out the interference to other signals (POTS41 and ADSL42) of upper transmission of the comfortable same phone, in conversion High pass filter (HPF) 32 is connected between device 31 and phone wiring connectors 36.In view of OFDM modem 30 to be coupled To phone pair, phone wiring connectors 36 is typically the telephonic standards RJ-11 plug used in North America.HPF32 can use reality The passive block of existing Butterworth filter scheme.In certain situations it is desirable to telephone unit shares identical phone wiring Adapter 35.In this case, low pass filter (LPF) 34 isolation POTS frequency band will be used, it is allowed to telephone set is via phone Socket (such as, RJ-11 socket) coupled to phone connector 35.Any filtering being commonly used in isolation POTS and ADSL signal Device (also known as micro-filter) can be used as LPF34, including discrete electric capacity and inductance.Connect via one group of LPF and HPF unit Modem and this configuration of phone are well known in the art and the most generally use in HomePNA environment.

Known OFDM and other spread spectrum modulation techniques are powerful, healthy and strong and high-performance.But, its implementation complexity and Relevant cost has used generation impact in a communications system for them.First the WLAN technology introduced uses single load Wave technology, such as uses the IEEE802.11b of CCK.Therefore, the OFDM modem 30 shown in Fig. 3 can serve as based on electricity The super replacement of prior art HomePNA of words line communication.Owing to using powerful OFDM technology, it is therefore desirable for modem Performance is beyond the HomePNA technology of single-carrier modulated (such as QAM) any available or that future usage is known in the art.And And, due to modem utilize existing need not customize towards wireless assembly such as wireless MAC 13b, baseband processor 18 With RF-IF changer 16, it is thus eliminated that exploitation dedicated modem required for effort.Further, for house, office The quick surge of the wlan solution of room, enterprise and commercial Application, it is desirable to trend be to continue to increase in future, this shows greatly The wlan component of amount creates simple availability, low price and assurable interoperability.

Known to the above-mentioned up/down changer 31 for frequency displacement is in the art.These changers are known as using and mix Frequency and filtering technique, and single or multiple level (superhet scheme) can be used and directly convert (DC) architecture.For Fig. 3 Shown in include that power converter cells 31, RF wave filter 21 and TX/RX switch the non-limit of the up/down inverter functionality square 37 of 19 functions Property example processed is shown as square 50 at Fig. 5.The frequency displacement of this square 50 coupled to the RF signal of port 51 to the low frequency in port 68 (IF) signal.The RF signal received in port 51 is by the descending letter of 58a based on frequency mixer 57a and band filter (BPF) Road exports to bottom offset and at port 68.Similarly, in port 68 receive IF signal by include frequency mixer 57a and The up channel of BPF58a is moved to RF frequency band, and exports at port 51 as RF signal.RF port 51 coupled to OFDM modulation HPF32 and the IF port 68 of demodulator 30 coupled to the RF-IF changer 16 of OFDM modem 30.

Although being sent to phone pair via adapter 36, but the RF received at port 51 (from RF-IF changer 16) believing Number first pass through BPF52 filtering and any undesired remain in RF channel band (such as, ISM RF channel band) outward to remove The signal in portion.Owing to changer 50 allows only to convert in a direction every time, or up or down, so using gang switch 56a and 56b, has the central rods being labeled as (1) and two mobile status being labeled as (2) and (3).When transforming to IF from RF Time, two switch 56a and 56b are in (2) state, so down channel is operable.This switch can be based on as above PIN diode about switch 19.RF signal from RF port 51 coupled to frequency mixer 57a via BPF52 and switch 56a. Frequency mixer 57a multiplexing is supplied to local oscillator 54 sine wave signal of its LO port via separator 55 and coupled to it The RF signal (use nonlinear characteristic) of RF port, produces the signal with two fundamental components, one-component at its IF port Frequency summation around and one-component around its difference on the frequency.Then by the summing signal of BPF58a frequency filtering, and Feed IF port 68 via switch 56b.Driver 59 can also be included to allow the load of correctly drive connection port 68. In a similar manner, when docking the time receiving from phone, from port 68 (in phone centering origin, and via adapter 36 and HPF32 Coupling) IF signal via switch 56b (being now arranged in state (3)) route and via the IF port of BPF58b to frequency mixer 57b. Signal is also fed to the LO part of frequency mixer 57b from local oscillator 54 via separator 55, and this frequency mixer is via switch 56a (being now arranged in state (3)) and BPF52 output RF signal is to port 51.Level detector (or comparator) 53 is used for monitoring reception The level of RF signal, and the most respectively via controlling channel 69b and 69a operation switch 56a and 56b.

Have been described with changer 50 and there is dedicated uplink and down channel.But, owing to the most only using a channel And two channels can not be used simultaneously, it is also possible to use individual channel (frequency mixer), single channel is applied suitable switching machine System.

Level detector 53 can be based on from National Semiconductors headquartered in Santa- Clara, CA U.S.A obtainable LM311 voltage comparator designs.Local oscillator 54 can based on quartz oscillator, Wherein using phaselocked loop (PLL) circuit to be multiplied by this frequency, this agitator can include that T83027PLL clock generator IC, this IC have Having the VCXO obtained from TLSI Incorporated ofHuntington, NY U.S.A, its tables of data comprises at this draws work and joins Examine.Frequency mixer 57 can design based on MAX9993 High Linear 1700MHz down conversion mixer, and this frequency mixer has from Maxim Integrated Products of Sunnyvale, CA U.S.A obtainable LO buffer/switch, its tables of data is wrapped at this Containing incorporated by reference.It should be noted that and realize the other technologies of changer square 50 function and method is well known in the art also And can use equally.Typically, changer square 50 can use line interface function such as to isolate, impedance matching, drive Move/receive and filter connection phone wiring, as following by the description for line interface 76 shown in Fig. 6.

OFDM modem 30 substantially applies bifrequency to convert: by changer 16 from IF to RF and by conversion Device 31 returns to low frequency.This redundancy can be eliminated without RF level, such as example in Fig. 6 by extracting directly baseband signal Shown in OFDM modem feature square frame Figure 60, wherein can be able to use in the one or more embodiments of the present invention It.

Being similar to modem 30, modem 60 is based on the WLAN unit 10 described in Fig. 1.But, at broadband The OFDM baseband signal not frequency displacement that reason device 18 produces is to RF, but directly processes in IF frequency spectrum.A non-limiting reality In example, baseband processor 18 provides orthogonal simulation i/q signal pair.In this case, divide carrying out frequency spectrum according to chart 40 In the example joined, use the line interface 76 of quadrature modulator/demodulator 191 shown in Fig. 6 a that signal is directly converted to center and exist Base-band analog signal (such as using 19MHz local oscillator) around 19MHz.In another example, by including base band The wlan component output center of processor 18 is in the analogue signal of another frequency components, and can use in this case Simple and single-frequency converts signal center to be positioned at around 19MHz.

The functional-block diagram of line interface 76 is shown in Fig. 6 a.Line interface 76 coupled to base band via port 192 I-Q manipulator 15 in processor 18.By quadrature modulator/demodulator 191, I-Q signal is transformed into center at 19MHz frequency Single real signal (from zero shift) around rate, this 191 can be based on from Maxim Integrated Products of The MaximMAX24503V of Sunnyvale, CA U.S.A, ultra low power quadrature modulator/demodulator realizes, and its tables of data is at this Comprise incorporated by reference.The output impedance of modulator/demodulator be resistance 190 (the need to) terminate 75 ohm, and via only It is fed to driver 186 by the BPF 188a of required frequency band (such as, the frequency band 43 in chart 40).Analog switch 183 via Isolated location 182 signal sent by port 181 route connect up (via port 36 and HPF32) to phone.Isolated location 182 typical cases are based on signal converter 193, and are used as to reduce common-mode noise to provide the signal of balance, and meet U.S. UL Safety needed for applying with Europe CE and ESD requirement.

Similarly, isolated the signal received from phone wiring by isolated location 182, and route via analog switch 183 To AGC187.100 ohmages 185 are used as termination, coupling phone Wiring features impedance to avoid reflection.Passing through BPF188b After filtering, modulate this signal by manipulator 191I-Q and coupled to baseband processor 18.

Radio port

Above-mentioned OFDM modem 30 and 60 provides the wiring of two cable ports, i.e. data unit port 33 and phone Port 36, its function is to convert signal between the ports.Adding radio port will make OFDM modem also be able to Network with data cell on non-wired medium.

Figure 10 illustrates this OFDM modem 100 and include the antenna 22 as radio port.Generally, it is possible to Think that this modem 100 is the WLAN unit 10 and OFDM modem 30 above with reference to described in Fig. 1 and 3 respectively Combination.Shown modem 100 includes whole WLAN unit 10 function, may also serve as WLAN unit 10.But, RF Signal is coupling between RF-IF changer 16 and TX/RX switch 19 by shared equipment 101.Therefore RF signal is also via up/down Changer 31 and HPF32 coupled to phone wiring connectors 36, is similar to the above description about OFDM modem 30.Class As, telephone set can couple via adapter 35 and LPF34.

Sharing equipment 101 is three port devices and for sharing three RF signals, therefore multiple by other two ports Make and be shared in any one port the RF signal received.One RF signal has with via the wireless radio communication of antenna 22 Closing, second signal transmits that signal is relevant and the 3rd RF signal and FPDP 33 phase with connecting up via the phone of adapter 36 Close.

In this configuration, OFDM modem 100 is via three port communications: via antenna 22 radio port, Cable data unit port via adapter 33 and telephone wiring connectors 36.From the data sheet connected via port 33 The packet (such as Ethernet packet) that unit receives will be converted into OFDM RF signal at RF-IF changer 16 port, then Warp after downconverted to baseband signal by up/down changer 31 and HPF32 (such as the above description to modem 30) Being fed to phone wiring by shared equipment 101, parallel (via shared equipment 101) is fed to antenna 22 aloft to send.Class As, the OFDM RF signal received in antenna 22 is fed to phone cloth line end via shared equipment 101 with ABB form Mouth 36 is also fed to data unit port 33 as digital packet.The baseband signal received via phone wiring port will be transformed Become RF and be then sent in the air at port 33 by antenna 22, wherein RF signal parallel underground frequency transformation and be encoded into number The packet of font formula.In some cases, (via port 36) can be connected up from antenna 22 and phone and receive RF signal.Due to nothing Wire system can process by aerial many through phenomenon, and the signal received via phone wire laying channel is construed as another bars Passage, is then processed by baseband processor 18.

Three shown port modems 100 share three RF signals by shared equipment 101.In the present invention one Or in more embodiment, base band (or IF) frequency spectrum performs sharing functionality.Figure 10 a shows this modem 105. It is similar to modem 100, supports three ports, two of which cable port and a radio port.But, with modulatedemodulate Adjust device 100 contrary, share equipment 106 and share three baseband signals: signal that antenna 22 couples via RF-IF changer 16, warp Phone pds signal by interface 76 and the data cell coherent signal via baseband processor 18.One advantage of this configuration It is to use two changers (16 and 31) used in single up/down changer 16 rather than modem 100 configuration.

Be similar to about OFDM modem 30 and 60 is described above, possesses the modem 100 of radio port Can be encapsulated in equally in telephone socket or snap-on module with 105.Figure 11 shows this snap-on mould being attached to telephone socket 91 Block 110.Module 110 is similar to the module 90 shown in Fig. 9, but except for the difference that uses screw 111a and 111b rather than pass through Snap-fit connection is attached to socket.It should be noted that and can similarly use other mechanical connecting devices.Shown in module 90 Cable port outside, further it is shown that be used as the antenna 22 of additional on-air radio port.

Figure 12 illustrates the network 120 using the radio port possessing OFDM modem 100.Can similarly answer With OFDM modem 105.Network 120 is based on the network 75 shown in Fig. 6 b, and wherein OFDM modem 100a replaces OFDM modulation /demodulation 30b, therefore introduces radio port 22a to network.Computer 66a and telephone power 65a is with the most front similar Mode connect OFDM modem 100a.Additional port 22a allows laptop computer 66c to be connected to include antenna 22b Wireless bridge 121a.Similarly, during wireless client function 121a can be built in computer 66c.According to standard The wireless link of IEEE802.11g is between bridge 121a and modem 100a, so that computer 66c can be with It is connected to other data cells networking of phone wiring 62 and computer 66a.

Although individual modem 100 or 105 is a part for network 120, it should be appreciated that can use multiple This modem, the zones of different in each covering house, so expanding the wireless coverage of reality.And, this A little networks 120 provide the user by wiring (by being connected to the FPDP of OFDM modem) or wirelessly (warp By radio port) add data cell motility.
