[0006] Wireless gigabit alliance (WiGig) or institute of electronic and electrical engineers (IEEE) 802.1 1 ad are wireless communication standards associated with using a wireless wave band of 60 gigahertz. WiGig communication may rely on a WiGig component such as a WiGig antenna and/or a WiGig chip to facilitate aspects of the WiGig communication. For instance, a WiGig chip can be a 60 gigahertz

complementary metal-oxide semiconductor (CMOS) WiGig chip, among other suitable WiGig chips. A WiGig antenna refers to antennas and antenna arrays that can transmit and/or receive information operating in the 60 GHz frequency spectrum (i.e., DBand) as defined by the WiGig specification. The WiGig antennas and WiGig antenna arrays may be beam steerable or directed beam antennas or antenna arrays, among other possibilities.

[0007] Some example approaches to providing a WiGig component to a communication apparatus (e.g., a laptop) may rely a WiGig component being non- removably coupled (e.g., soldered) to a platform such as a printed circuit board (PCB) of a communication apparatus. Non-removably coupling the WiGig component to the platform can add to a base cost of the communication apparatus, increase difficulty to manufacture the communication apparatus, and/or reduce an amount of available area in which other components (e.g., a wireless local area network (WLAN) and/or a wireless wide area network (WWAN) antennas) can be coupled to the platform.

Further, not all end users of the communication apparatus may desire to utilize such WiGig components and/or WiGig communication.

[0008] Examples of the disclosure are directed to WiGig accessories, WiGig enabled computing systems including WiGig accessories, and methods of forming the WiGig enabled computing systems including WiGig accessories. WiGig accessories refer to devices including a WiGig component that can form a WiGig enabled

communication system having a wireless peripheral component interconnect express (PCIe) communication capability when coupled to a computing device. For example, a WiGig accessory can include a connector to couple the WiGig accessory to a universal serial bus (USB) port of a computing device that is separate and distinct from the WiGig accessory and a WiGig component to form a WiGig enabled communication system having a wireless PCIe communication capability when coupled to the computing device.

[0009] A WiGig enabled communication system refer a system having at least a PCIe communication capability (e.g., a PCIe communication capability and a

DisplayPort communication capability) when coupled to a WiGig accessory. That is, a WiGig component is located in a WiGig accessory that is separate and distinct from a platform of the computing device. Locating the WiGig component off the platform of the computing device provides a comparatively greater amount of physical space on the platform of the computing device for other components such as antennas to be installed and provides for comparatively reduced costs associated with manufacture of the computing device. That is, a WiGig component (e.g., the WiGig antenna and/or a WiGig chip) are physically removed from a platform (e.g., a PCB) of the computing device and are instead capable of being removably coupled to the computing device to form a WiGig enabled communication system.

[0010] Figure 1 illustrates a schematic view of an example of a WiGig enabled computing system 100 including a WiGig accessory according to the disclosure. The Wigig enabled computing system 100 includes a computing device 1 10, a WiGig accessory 130 including a WiGig component 133, and an electronic device 150. The computing device 1 10 is analogous to computing device 210 referenced by Figure 2 and the WiGig accessory 130 is analogous to WiGig accessory 330 referenced by Figure 3.

[0011] The computing device 1 10 refers to an electronic device suitable to process information and perform WiGig communication when coupled to a WiGig accessory, as described herein. The computing device 1 10 may not include a WiGig antenna and/or may not include a WiGig chip in an effort to ease manufacture of the computing device 100, provide additional physical real estate on the computing device 1 10 for other components, and/or to comparatively reduce a cost associated with manufacture of the computing device 1 10 as compared to other computing devices that may include a WiGig antenna and/or a WiGig chip. That is, the computing device 1 10 may not be capable of performing WiGig communication when decoupled from a WiGig accessory due at least in part to the computing device including various components other than a WiGig antenna and/or a WiGig chip. Examples of computing devices can include mobile devices, payment instruments, tablets, desktop computers, and/or laptop computers, among other types of computing devices that can form a WiGig enabled communication system having a wireless PCIe communication capability when coupled to a WiGig accessory.

[0012] The computing device includes a first demultiplexor and a second demultiplexor, as described herein with greater detail at Figure 2. Notably, the second demultiplexor is coupled to a PCIe bus (not shown) of the computing device 1 10 to form a WiGig path extending from the PCIe bus through the second demultiplexor. That is, the presence of the second demultiplexor in the computing device 1 10 can permit formation of the WiGig enabled communication system 100. For example, the WiGig path can extend from the PCIe bus through the second demultiplexor to the WiGig component 133 (e.g., WiGig chip and/or a WiGig antenna) when the WiGig accessory 130 is coupled to the computing device 1 10 to form the WiGig enabled communication system 100 having a wireless PCIe communication capability. If the second

demultiplexor were not present in the computing device 1 10 the WiGig enabled communication system may not be formed. Formation of a WiGig path and/or non- removably coupling a WiGig accessory 130 to computing device 1 10 can comparatively increase an amount of available area in which other components can be coupled to a platform (e.g., a PCB) of the computing device 1 10. For instance, the computing device 1 10 can include WLAN and/or WWAN antennas coupled to a platform of the computing device 1 10.

[0013] The WiGig accessory 130 is a dongle or other device that can removably coupled (e.g., via a USB plug) to the computing device 1 10 (e.g., coupled to a USB port of the computing device) and form the WiGig enabled communication system 100 when removably coupled to the computing device 1 10. As mentioned, the WiGig accessory 130 includes a WiGig component 133. The WiGig component 133 can include a WiGig antenna that can communicate wireless PCIe information and/or can include a WiGig chip. The WiGig chip is compliant with the IEEE 802.1 1 ad standard and/or a Wireless gigabit alliance, among other possibilities. That is, the WiGig enabled communication system 100 can wirelessly transmit and/or receive PCIe communication to and/or from the electronic device 150. In some examples, the WiGig enabled communication system 100 can have both the wireless PCIe communication capability and a wireless DisplayPort (DP) communication capability when coupled to the computing device. For example, the WiGig communication system 100 can enable wireless docking of the computing device 1 10 when coupled to the WiGig accessory by pass through both wireless PCIe and wireless DP to the electronic device (e.g., a docking station and/or a monitor). However, the present disclosure is not so limited. Rather, WiGig

communication via the WiGig enabled communication system 100 can, in some examples, include utilization of a PCIe communication capability of the WiGig enabled communication system 100 and not employ a wireless DP capability.

[0014] The WiGig accessory 130 and the computing device 1 10 are separate and distinct. Being separate and distinct refers to being physically separate and having separate resources. That is, when coupled the WiGig accessory 130 and the computing device 1 10 can form the WiGig enabled communication system 100.

[0015] The electronic device 150 refers to displays (e.g., monitors, televisions, etc.) mobile devices, payment instruments, tablets, desktop computers, and/or laptop computers, among other types of electronic devices that can transmit and/or receive WiGig communications such as wireless PCIe and/or wireless DP communications. As illustrated in Figure 1 , the electronic device 150 includes WiGig antenna 152. The WiGig antenna 152 can be similar or analogous to a WiGig antenna included in the WiGig accessory 130. For instance, the WiGig antenna 152 can refer to antennas and antenna arrays that can transmit and/or receive information operating in the 60 GHz frequency spectrum as defined by the WiGig specification. The WiGig antennas and WiGig antenna arrays may be beam steerable, or directed beam antennas or antenna arrays, among other possibilities.

[0016] Figure 2 illustrates schematic view of an example of a portion of computing device 210 included in the WiGig enabled computing system of Figure 1 according to the disclosure. As illustrated in Figure 2, the computing 210 includes an outer housing 21 1 including a port 224 that is in communication with a controller 220 via a communication channel 222 and the port 224 is in communication with a first demultiplexor 212 and a second demultiplexor 214. The first demultiplexor 212 and the second demultiplexor 214 are demultiplexors (e.g., high-speed demultiplexors capable of operation at comparatively higher speeds than other demultiplexors which may not be suitable for WiGig communication) that are suitable to provide WiGig communication. As mentioned, the WiGig path can extend from a PCIe bus (not shown) through the second demultiplexor 214 to a WiGig component (e.g., WiGig chip and/or a WiGig antenna) included in a WiGig accessory when the WiGig accessory is coupled to the computing device 210 to form the WiGig enabled communication system having a wireless PCIe communication capability. The second demultiplexor can be in

communication with a DP channel (not shown) to pass through DP to the port 224. That is, the second demultiplexor can pass though DP (e.g., DPx2 or DPx4) and/or PCIe. For example, DPx4 can be passed through the second demultiplexor and the port 224 to (e.g., to and/or from) an electronic device when the WiGig enabled system, as described herein, is formed.

[0017] A PCIe communication can be communicated from the PCIe bus via the PCIe channel 216 to the first demultiplexor 212. Similarly, a USB communication (e.g., a USB 3.0 or other version of USB) can be communicated via a USB channel 218 to the first demultiplexor 212. As a result, the first demultiplexor can pass PCIe

communication and/or USB communication to the second demultiplexor 214. Notably, a PCIe communication can be communicated via a portion of the WiGig path 213-1 to the second demultiplexor 214. Such a communication can be communicated from the second demultiplexor 214 via a portion of the WiGig path 213-2 to the port 224. That is, a portion of the WiGig path is illustrated as 213-1 and 213-2 in Figure 2. The port 224 can operate based on instructions received from the controller 220, among other possibilities.

[0018] The controller 220 can include hardware components and/or computer- readable and executable instructions to form a WiGig path and/or to promote

communication of information via the WiGig path, among other possibilities. The instructions (e.g., software, firmware, programming, etc.) may be stored in a memory resource (e.g., computer-readable medium) or as a hard-wired program (e.g., logic). For example, the controller 220 can include a number of engines can include a combination of hardware and instructions to perform a number of functions described herein (e.g., form a WiGig enabled computing system having a WiGig path extending from the PCIe bus through the second demultiplexor to the WiGig component of the WiGig accessory and enable wireless PCIe communication between the WiGig enabled computing system and an electronic device, etc.). Each of the engines can include hardware or a combination of hardware and instructions. The controller 220 can be implemented on a computing device and/or a collection of computing devices, on a WiGig accessory and/or a collection of WiGig accessories, and/or on a combination of a computing device and a WiGig accessory.

[0019] The port 224 can be a type-C USB port. A type-C USB port can operate in a plurality of modes including a USB mode, a DP mode (e.g., with shared USB and DP), and notably, a WiGig mode. When in the WiGig mode, the type-C USB can facilitate WiGig communication. For instance, the type-C USB can enter a WiGig mode and/or form a WiGig path in response to receipt of a WiGig vender defined message (VDM) that puts the type-C USB port into the WiGig mode and/or cause formation (e.g., completion) of the WiGig path to occur.

[0020] Figure 3 illustrates schematic view of an example of a portion of a WiGig accessory 330 included in the WiGig enabled computing system of Figure 1 according to the disclosure. The WiGig accessory 330 is a dongle or other device that can removably couple to the computing device 1 10 and form the WiGig enabled

communication system 100 when removably coupled to the computing device 1 10.

[0021] As illustrated in Figure 3, the WiGig accessory 330 can include plug 332, WiGig chip 334, and WiGig antenna 336. In various examples, a WiGig component, as described herein, includes at least one of the WiGig chip 334 and/or the WiGig antenna 336. For instance, as illustrated in Figure 3, a WiGig component (not shown for ease of illustration) of the WiGig accessory 330 can include both the WiGig chip 334 and the WiGig antenna 336. However the present disclosure is not so limited. That is, the WiGig accessory 330 can include a WiGig antenna but not a WiGig chip or can include a WiGig chip but not a WiGig antenna. For example, when the WiGig accessory includes a WiGig chip but does not include a WiGig antenna a computing device and/or another WiGig accessory can include a WiGig antenna, among other possibilities to promote formation of a WiGig enabled communication system. Similarly, when the WiGig accessory 330 includes a WiGig antenna but does not include a WiGig chip the computing device and/or another WiGig accessory can include a WiGig chip, among other possibilities to promote formation of a WiGig enabled communication system.

[0022] As mentioned, the WiGig antenna 336 refers to WiGig antennas and WiGig antenna arrays may be beam steerable, or directed beam antennas or antenna arrays. Such WiGig antennas and WiGig antenna arrays may be planar, three dimensional, or other configurations, among other possibilities.

[0023] The WiGig antenna 336 can be connected to separate transmit and receive chains, or a combined transmit and receive switch. The WiGig antenna arrays can include a number of elements, and antenna array elements may be arranged to form a one or two dimensional array. The WiGig antenna 336 can radiate or transmit radio waves perpendicular to array orientation (e.g., radiating in the z-axis to a Wigig antenna array arranged in the y-axis, or radiating in the z-axis to a planar antenna array arranged in the x-y plane). Such radiation may be referred to as broadside radiation. In certain implementations, a WiGig antenna 336 can radiate or transmit radio waves in the same directions as the array orientation (e.g., radiating in the y-axis to a WiGig antenna array arranged in the y-axis, or radiating on the x-y plane to planar antenna array arranged in the x-y plane). Such radiation may be referred to as end fire radiation. That is, the WiGig antennas and antenna arrays may provide for broadside and/or end fire radiation, among other possibilities. In any case, the WiGig antenna 336 is physically removed from a platform (e.g., a PCB) of a computing device (e.g., computing device 1 10 as illustrated in Figure 1 ) and is instead capable of being removably coupled to the computing device (e.g., to a port of the computing device).

[0024] As mentioned, the WiGig chip 334 can be a 60 gigahertz CMOS WiGig chip, among other suitable WiGig chips. The plug 336 can be a USB plug such a type- C USB plug suitable to removably couple with a type-C USB port included in a computing device, among other possibilities.

[0025] A portion of a WiGig path illustrated as 313-3 and 313-4 can be included in the WiGig accessory. For instance, when the WiGig accessory is removably coupled to a computing device (e.g., computing device 210 as illustrated in Figure 2), a WiGig enabled computing system can be formed using at least such a portion of a WiGig path. For example, a WiGig enabled computing system can have a WiGig path extending from a PCIe bus through a second demultiplexor to the WiGig component via the portion of the WiGig path included in the WiGig accessory to enable wireless PCIe communication between the WiGig enabled computing system and an electronic device (e.g., electronic device 150 as illustrated in Figure 1 ).

[0026] Figure 4 illustrates a flow diagram of an example of a method of forming a WiGig enabled computing system including a WiGig accessory according to the disclosure. As illustrated at 484, the method 480 can include providing a computing device including a PCIe bus, a type-C USB port, a first demultiplexor, and a second demultiplexor. Similarly, the method 480 can include providing a WiGig accessory including a WiGig component, as illustrated at 486. Providing can include manufacture of and/or otherwise procuring the computing device and the WiGig accessory.

[0027] As illustrated at 488, the method 480 can include coupling the WiGig accessory to the type-C USB port of the computing device to form a WiGig enabled computing system having a WiGig path extending from the PCIe bus through the second demultiplexor to the WiGig component of the WiGig accessory and enable wireless PCIe communication between the WiGig enabled computing system and another device. As mentioned, the WiGig path can enable WiGig communication with the electronic device.

[0028] In some examples, the method 480 can include including forming the WiGig path in response to receipt of a WiGig VDM that puts the type-C USB port into a WiGig mode and forms the WiGig path. The WiGig VDM refers to instructions that cause the type-C USB port to enter a WiGig mode (enabling WiGig communication via the type-C USB port). For example, receipt of such a WiGig VDM by the type-C USB port can occur in response (e.g., automatically without a user request) to coupling the WiGig accessory and/or place the type-C USB connecting in a WiGig mode

automatically.

[0029] It will be understood that when an element is referred to as being "on," "connected to", "coupled to", or "coupled with" another element, it can be directly on, connected, or coupled with the other element or intervening elements may be present. In contrast, when an object is "directly coupled to" or "directly coupled with" another element it is understood that are no intervening elements (adhesives, screws, other elements) etc.

These examples are described in sufficient detail to enable those of ordinary skill in the art to practice the examples of this disclosure, and it is to be understood that other examples (e.g., having different thickness) may be utilized and that process, electrical, and/or structural changes may be made without departing from the scope of the disclosure.

[0031] The figures herein follow a numbering convention in which the first digit corresponds to the drawing figure number and the remaining digits identify an element or component in the drawing. For example, reference numeral 105 may refer to element 1 10 in Figure 1 and an analogous element may be identified by reference numeral 210 in Figure 2.
