`
`INSTALLATION OF WIRELESS LOCAL AREA
`NETWORK DEVICE INTO A LAPTOP COMPUTER
`
`FIELD AND BACKGROUND OF THE
`INVENTION
`
`[0001] The present invention relates to a Wireless local
`area network device and, in particular, it concerns installa
`tion of a Wireless local area netWork device into a laptop
`computer.
`[0002] By Way of introduction, Wireless local area net
`Work (WLAN) devices enable laptop computers to establish
`a local area netWork and to communicate Wirelessly With
`other computers via the WLAN devices. Each WLAN
`device has an antenna Which is preferably installed in the
`display cover of the laptop computer so that When the
`display cover is open, the WLAN antenna is unobstructed,
`thereby enabling larger Wireless coverage.
`
`[0003] Of rnost relevance to the present invention is a
`prior art system whereby the WLAN device, Without the
`antennas, is installed on the laptop motherboard and the
`antennas are installed in the display cover. RF cables are
`routed betWeen the WLAN device on the motherboard and
`antennas in the display cover. A shortcoming of the afore
`mentioned system is due to the high relative cost of RF
`cable. A further shortcoming of the aforementioned system
`is that there is a signal loss in the RF cable of several dB’s.
`
`[0004] Also of relevance to the present invention is a prior
`art system whereby the complete WLAN device, including
`antennas, is installed in the display cover. A USB interface
`is used to interconnect betWeen the processor on the moth
`erboard and the WLAN in the display cover. Routing of the
`USB interface cable betWeen the motherboard and the
`display cover is simple and inexpensive. HoWever, this
`implementation causes unnecessary power consumption, as
`the USB host rnust periodically poll all USB devices,
`although there may be no data to be received from that
`device as only a USB host can initiate data transfer.
`
`[0005] There is therefore a need for an inexpensive, easy
`and energy ef?cient system to install a WLAN device
`antenna in a display cover of a laptop computer.

`
`DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`
`[0028] The present invention is a system and method for
`providing a link betWeen a processor and a Wireless com
`munication device in a laptop computer. The principles and
`operation of a link betWeen a processor and a Wireless
`communication device in a laptop computer according to the
`present invention may be better understood With reference to
`the draWings and the accompanying description.
`
`[0029] Reference is noW made to FIG. 1, Which is a
`schematic vieW of a portable computer system 8 having an
`Ethernet link 10( betWeen a processor 22 and a Wireless
`communication device 14 that is constructed and operable in
`accordance With a preferred embodiment of the invention.
`Computer system 8 is typically a laptop computer having a
`loWer housing 16, a display cover 18 and a hinge arrange
`ment 20, hinge arrangement 20 being con?gured to
`mechanically connect loWer housing 16 and display cover
`18. Computer system 8 includes processor 22 Which is
`disposed on a motherboard 12 Within loWer housing 16.
`Processor 22 includes the central processing unit and sup
`porting core logic chips of computer system 8. Wireless
`communication device 14 is disposed Within display cover
`18. Wireless communication device 14 is typically a WLAN
`device. Wireless communication device 14 has one or more
`
`antennas 26. Ethernet link 10 is con?gured so as to at least
`partially de?ne a communication link betWeen processor 22
`and Wireless communication device 14. Therefore, opera
`tionally connecting processor 22 and Wireless communica
`tion device 14 via Ethernet link 10 enables computer system
`8 to communicate With one or more remote devices via
`Wireless communication device 14. Part of Ethernet link 10
`is disposed Within loWer housing 16 and part of Ethernet link
`10 is disposed Within display cover 18. Ethernet link 10
`includes an Ethernet cable 36 Which eXtends from loWer
`housing 16 to display cover 18. Additionally, other Ethernet
`devices are needed to form Ethernet link 10. It Will be
`apparent to those ordinarily skilled in the art that Ethernet
`link 10 can be formed using a variety of Ethernet compo
`nents and devices.
`
`[0030] The system of the present invention has the advan
`tage of Wireless communication device 14 and antennas 26
`being disposed in display cover 18, so that When the display
`cover 18 is open, antennas 26 are unobstructed, thereby
`enabling larger Wireless coverage. Additionally, the inter
`connection betWeen processor 22 and Wireless communica
`tion device 14 is via Ethernet link 10. Using the mature and
`proven Ethernet technology to interconnect betWeen proces
`sor 22 and Wireless communication device 14 Which is
`disposed in display cover 18, results in a simple, inexpensive
`and high performing overall implementation. Moreover, all
`advanced laptop computers, currently under design or pro
`duction, include built-in support for both Wired (such as
`IEEE 802.3 Ethernet) and Wireless (such as IEEE 802.11 a
`or b or g) connection to a local area netWork
`Wired
`(standard) Ethernet interface 30 is generally connected to a
`Wired LAN port 32 having an R145 socket for connection to
`a Wired LAN. The Wireless LAN connection is typically
`provided via all interface (not shoWn) to a Wireless com
`munication device, such as a WLAN device. The laptops are
`generally con?gured so that either Wired (standard) Ethernet
`interface 30 or the Wireless interface is active at a certain
`time. Therefore, the Ethernet link 10 of the present invention
`can be con?gured to include at least part of eXisting Wired
`(standard) Ethernet interface 30, Which is located on moth
`erboard 12. Ethernet link 10 also includes a sWitching
`system 34 Which routes data from processor 22 either to
`Wired LAN port 32 When Wired LAN port 32 is active, or to
`Wireless communication device 14 When Wired LAN port 32
`is inactive. Alternate embodiments of sWitching system 34
`are described beloW With reference to FIGS. 2 to 5. Addi
`tionally, Ethernet link 10 and/or processor 22 is con?gured
`to actuate a poWer save mode of Wireless communication
`device 14 When Wired LAN port 32 is active. This aspect of
`the invention is described in more detail With reference to
`FIGS. 2 to 5.
`
`[0031] Using Ethernet link 10 betWeen processor 22 and
`Wireless communication device 14 has the folloWing advan
`tages:
`a loW number of interconnecting Wires, typically 2
`analogue pairs; (ii) the length of Ethernet cable 36 does not
`distort or attenuate the signal, as compared With an RF cable
`connection; (iii) Ethernet is a Well knoWn, commonly used
`and loW cost technology and (iv) Wireless communication
`device 14 is maintained in a poWer save mode When Wired
`LAN port 32 is active.
`
`[0032] Reference is noW made to FIG. 2, Which is a
`schematic vieW of an Ethernet link 38 betWeen a processor

`
`Ethernet PHY chip 44 that is constructed and operable in
`accordance With a ?rst alternate embodiment of the inven
`tion. Ethernet link 38 de?nes a communication link betWeen
`processor 48 Which is installed on a motherboard 40 and
`Wireless communication device 42. Wireless communica
`tion device 42 is typically a WLAN device. Ethernet link 38
`includes tWo analogue pairs 54, dual Ethernet PHY chip 44
`and an Ethernet PHY chip 56. Dual Ethernet PHY chip 44
`is disposed on motherboard 40. Dual Ethernet PHY chip 44
`is operationally connected to processor 48 via tWo MII
`connections 64. Analogue pairs 54 connect Port2 of dual
`Ethernet PHY chip 44 to Ethernet PHY chip 56. Ethernet
`PHY chip 56 is operationally connected to Wireless com
`munication device 42 via an MII connection 58. A Wired
`Ethernet port 46 is operationally connected to Port1 of dual
`Ethernet PHY chip 44 using tWo analogue pairs 60. Dual
`Ethernet PHY chip 44 supports the connection betWeen
`processor 48 and Wired Ethernet port 46 as Well as the
`connection betWeen processor 48 and Wireless communica
`tion device 42. An eXample of a suitable dual Ethernet PHY
`chip 44 is LXT973, Which is commercially available for
`Intel Corporation of 2200 Mission College Blvd., Santa
`Clara, Calif. 95052, USA. It Will be appreciated by those
`skilled in the art that dual Ethernet PHY chip 44 may be
`replaced by tWo suitable single PHY chips. Either Wired
`Ethernet port 46 or Wireless communication device 42 is
`operational at one time under the control of processor 48
`through a MDIO interface 52 of dual Ethernet PHY chip 44.
`Processor 48 is con?gured, typically by softWare running
`thereon, to sense When Wired Ethernet port 46 is active or
`inactive. When Wired Ethernet port 46 is active, processor 48
`actuates dual Ethernet PHY chip 44 to disconnect the
`communication link betWeen processor 48 and Wireless
`communication device 42 by disconnecting Port2 of dual
`Ethernet PHY chip 44. Ethernet PHY chip 56 of Ethernet
`link 38 is con?gured to sense the disconnection of Port2 of
`dual Ethernet PHY chip 44 and thereby force the remaining
`part of Wireless communication device 42 to enter a poWer
`save mode via a GPIO (general purpose in/out) interface 62
`of Wireless communication device 42.
`
`[0033] Reference is noW made to FIG. 3, Which is a
`schematic vieW of an Ethernet link 66 betWeen a processor
`74 and a Wireless communication device 70 using a sWitch
`arrangement, Ethernet sWitch 72, that is constructed and
`operable in accordance With a second alternate embodiment
`of the invention. Processor 74 is installed on a motherboard
`68. Ethernet link 66 includes Ethernet sWitch 72, an Ethernet
`PHY chip 76 and tWo analogue pairs 78. Ethernet sWitch 72
`is disposed on motherboard 68 and is operationally con
`nected to processor 74 via an MII connection 80. Analogue
`pairs 78 connect Port2 of Ethernet sWitch 72 to Ethernet
`PHY chip 76. Ethernet PHY chip 76 is connected to Wireless
`communication device 70 via an MII connection 82. A
`digital line 88 connects the LK1 port of Ethernet sWitch 72
`to the GPIO port of Wireless communication device 70. A
`Wired Ethernet port 84 having an RJ45 socket is connected
`to Port1 of Ethernet sWitch 72 via tWo analogue pairs 86.
`Ethernet sWitch 72 supports both the connection betWeen
`processor 74 and Wired Ethernet port 84 as Well as the
`connection betWeen processor 74 and Wireless communica
`tion device 70. Ethernet sWitch 72 Works in an unmanaged
`operation via strapping at system-reset time. When Port1 of
`Ethernet sWitch 72 senses that Wired Ethernet port 84 is
`active, Ethernet sWitch 72 is con?gured to disconnect the
`
`communication link betWeen processor 74 and Wireless
`communication device 70 by disconnecting Port2 of Ether
`net sWitch 72. Additionally, When Port1 of Ethernet sWitch
`72 senses that Wired Ethernet port 84 is active, Ethernet
`sWitch 72 deactivates Wireless communication device 70,
`actuating a poWer save mode of Wireless communication
`device 70, by sending a signal from the LK1 port of Ethernet
`sWitch 72 to the GPIO port of Wireless communication
`device 70. Wireless communication device 70 remains in
`poWer save mode until Port1 of Ethernet sWitch 72 no longer
`senses activity from Wired Ethernet port 84. Upon activation
`of Port2, a signal from the LK1 of Ethernet sWitch 72 is used
`to aWaken Wireless communication device 70. An eXample
`of a suitable Ethernet sWitch 72 is KS8993, Which is
`commercially available from Kendin Communications, Inc.
`of 486 Mercury Drive, Sunnyvale, Calif. 94086, USA.
`[0034] Reference is noW made to FIG. 4, Which is a
`schematic vieW of an Ethernet, link 90 betWeen a processor
`91 and a Wireless communication device 94 having a sWitch
`arrangement, the sWitch arrangement including tWo ana
`logue sWitches 96, 98 and an energy detector 100 that is
`constructed and operable in accordance With a third alternate
`embodiment of the invention. Processor 91 is installed on a
`motherboard 92. Ethernet link 90 includes a standard single
`Ethernet PHY chip 102 Which is connected to processor 91.
`Ethernet link 90 also includes a standard Ethernet PHY chip
`104 Which is connected to Wireless communication device
`94. The TX port of Ethernet PHY chip 102 is connected to
`analogue sWitch 96 via an analogue pair 106. The RX port
`of Ethernet PHY chip 102 is connected to analogue sWitch
`98 via an analogue pair 108. The TX port of Ethernet PHY
`chip 104 is connected to analogue sWitch 98 via an analogue
`pair 110. The RX port of Ethernet PHY chip 104 is con
`nected to analogue sWitch 96 via an analogue pair 112. The
`TX connection of a Wired Ethernet port 114 is connected to
`analogue sWitch 96 via an analogue pair 116. The RX
`connection of Wired Ethernet port 114 is connected to
`analogue sWitch 98 via an analogue pair 118. Analogue
`sWitch 96 is either implemented as tWo sWitches or a single
`differential sWitch. Analogue sWitch 96 is con?gured to
`route the TX signal from Ethernet PHY chip 102 to either
`Ethernet PHY chip 104 or Wired Ethernet port 114. Simi
`larly, analogue sWitch 98 is con?gured to route the RX
`signal from Wired Ethernet port 114 to Ethernet PHY chip
`102 or the TX signal from Ethernet PHY chip 104 to
`Ethernet PHY chip 102. Analogue sWitch 96 and analogue
`sWitch 98 are controlled by energy detector 100, Which
`senses When Wired Ethernet port 114 is active. When energy
`detector 100 senses the existence of an active RX signal of
`Wired Ethernet port 114, energy detector 100 provides a
`control signal to analogue sWitch 96 and analogue sWitch 98
`via a control line 115 thereby connecting Ethernet PHY chip
`102 to Ethernet PHY chip 104. Typically, Ethernet PHY chip
`104 is con?gured to sense the disconnection of Ethernet
`PHY chip 104 from Ethernet PHY chip 102 and thereby
`force the Wireless communication device 94 to enter a poWer
`save mode via a GPIO interface of Wireless communication
`device 94. Alternatively, Wireless communication device 94
`is forced into a poWer save mode by energy detector 100
`sending a signal to a GPIO port of Wireless communication
`device 94 via one or tWo digital control lines 120.
`[0035] Reference is noW made to FIG. 5, Which is a
`schematic vieW of an Ethernet link 122 betWeen a processor
`125 and a Wireless communication device 126 using a

`switch arrangement, the switch arrangement including tWo
`analogue sWitches 128 and a mechanically actuated sWitch
`130 that is constructed and operable in accordance With a
`fourth alternate embodiment of the invention. The sWitch
`arrangement establishes either a connection betWeen pro
`cessor 125 and Wireless communication device 126 or a
`connection betWeen processor 125 and a Wired Ethernet port
`132 having an R145 socket. The embodiment described With
`reference to FIG. 5 is substantially the same as the embodi
`ment described With reference to FIG. 4 except that energy
`detector 100 of FIG. 4 is replaced by mechanically actuated
`sWitch 130. Mechanically actuated sWitch 130 is con?gured
`to detect When the R145 socket of Wired Ethernet port 132
`is connected to a Wired local area netWork via an R145 plug
`(not shoWn). When the R145 plug is inserted into the R145
`socket of Wired Ethernet port 132, the R145 plug actuates
`mechanically actuated sWitch 130. When the R145 plug is
`connected to Wired Ethernet port 132, a logic level “0” is
`held on a control line 136, such that, Wireless communica
