The housing also includes a bottom housing member connected to the top housing member at a second end of the vertical wall. The bottom housing member has a bottom exterior surface and an opposing interior surface, wherein the bottom exterior surface defines a plane that is substantially perpendicular to the longitudinal axis of the cylinder. The bottom housing member includes a curved edge between the bottom exterior surface and the vertical wall of the top housing member. The antenna carrier supports multiple antennas operable to transmit and receive communication signals. In aspects, the antenna carrier has a substantially disk-shaped body and a plurality of flanges, with one of the plurality of flanges connected to one of the multiple antennas. The antenna carrier is positioned within the housing such that the multiple antennas are positioned proximate to the inner surface of the vertical wall. The circuit board assembly is positioned within the housing and is operable to provide a gateway to a wireless network. The heat sink is positioned between the antenna carrier and the circuit board assembly within the housing. The heat shield is proximate to the circuit board assembly to shield the circuit board assembly from electromagnetic interference. The circuit board assembly is positioned between the heat shield and the heat sink.
In aspects, a system is disclosed. The system includes a housing having first and second housing members sharing a common central axis and connected to each other. At least one of the first or second housing members includes side walls having a zero-draft inner surface and a partially-curved outer surface. The housing also includes rounded edges. Also, the system includes a plurality of dual-band antennas positioned within the housing proximate to the zero-draft inner surface of the side walls. Also, the system includes a circuit board assembly communicatively connected to the plurality of dual-band antennas to provide a gateway to a wireless network and a node to a wireless mesh network. Additionally, the system includes a heat sink positioned between the circuit board assembly and the plurality of antennas.
These are but a few examples of how the described techniques and devices may be used to enable an access point device. Other examples and implementations are described throughout this document. The document now turns to an example device, after which example systems are described.
Example Device
FIG. 1 illustrates a top front perspective view 100 of an example implementation of an access point device 102. The access point device 102 includes a housing 104 that has a substantially cylindrical shape with rounded edges. The housing 104 includes a central axis 106 (e.g., longitudinal axis). The housing 104 is simple, such that the housing 104 has a smooth exterior surface with few visible features. In aspects, the housing 104 includes a top housing member 108 and a bottom housing member 110.
As is further described below, the housing includes a seam 112 on an outer surface of the housing 104. The seam 112 is aligned with a location at which the top housing member 108 attaches to the bottom housing member 110. The top housing member 108 may be connected (e.g., threaded, snapped, fastened, pressed, glued, ultrasonic welded, etc.) to the bottom housing member 110.
The access point device is configured to provide access to a wireless network. In some aspects, the access point device can also serve as a node to a wireless mesh network. For example, the access point device can interface with a modem at a user's home to act as a wireless router for a local wireless network for the user.
FIGS. 2A to 2D illustrate various elevational views of the access point device 102. FIG. 2A illustrates a front elevational view 200 of the access point device 102 with the central axis 106 displayed vertically. The top housing member 108 includes a substantially vertical wall 202 that is generally cylindrical about the central axis 106 (e.g., the vertical wall has an x-axis radius substantially equal to a y-axis radius such that the x-axis radius is within an approximately ten millimeter tolerance of the y-axis). Also, the top housing member 108 includes a top-end portion 204 that is concave down in the front elevational view 200 such that the top-end portion 204 curves toward the vertical wall 202. The top-end portion 204 is connected to a first end (e.g., top end) of the vertical wall 202 via rounded edges 206.
The bottom housing member 110 shares the central axis 106 with the top housing member 108 and is connected to the top housing member 108 at a second end (e.g., bottom end) of the vertical wall 202, which is opposite the first end. The bottom housing member 110 includes rounded edges 208 that may have a similar radius to the rounded edges 206 of the top housing member 108. In the illustrated example 200, the bottom housing member 110 is substantially shorter in the direction of the central axis 106 than the top housing member 108, such that the seam 112 is located on the lower half of the housing 104. However, the bottom housing member 110 and the top housing member 108 can be any suitable height such that the seam 112 can be located at any location on the housing where the top housing member 108 is connected to the bottom housing member 110. A radius of the vertical wall 202 about the central axis 106 can be any suitable radius, such as a radius within a range of approximately 38 mm to approximately 65 mm.
The bottom housing member 110 includes a bottom exterior surface (not shown in FIGS. 2A to 2E) that defines a plane 210 that is substantially perpendicular to the central axis 106 (e.g., an angle between the plane 210 and the central axis 106 is within a five degree tolerance of a right angle). Connected to the bottom housing member 110 is a footpad 212 that provides friction. The bottom housing member 110 is positioned between the top housing member 108 and the footpad 212. The footpad 212 can be formed of any suitable material with a sufficiently high friction coefficient to reduce sliding between the housing 104 and a surface upon which the housing 104 is resting. The footpad 212 may be any suitable height, examples of which include a height within a range of approximately 0.5 millimeters to approximately 1.5 millimeters.
FIG. 2B illustrates a rear elevational view 220 of the access point device 102. As illustrated in the rear elevational view 220, the bottom housing member 110 includes an opening 222. The opening provides accessibility for cables (e.g., power cables, Ethernet cables, etc.) to connect to ports underneath the housing without causing the housing 104 to rest on the cables.
FIG. 2C illustrates a left elevational view 230 of the access point device 102. As illustrated, a profile of the opening 222 changes a curvature of the rounded edge 208 proximate to the opening 222 relative to the curvature of the rounded edge 208 at other portions. Similarly, FIG. 2D illustrates a right elevational view 240 of the access point device 102. Here, the opening 222 changes the curvature of the rounded edge 208. However, other edges, sides, and exterior surfaces of the housing 104 remain similar in each of the different elevational views 2A to 2D.
FIG. 3 illustrates a top plan view 300 of the access point device 102. Here, the access point device 102 is generally circular with no distinctive surface features. In the top plan view 300, the top-end portion 204 of the housing 104 is shown.
FIG. 4 illustrates a bottom plan view 400 of the access point device 102. The bottom housing member 110 includes an exterior cavity 402 formed by a portion of a bottom exterior surface, and the exterior cavity 402 is accessible via the opening 222. As is further described below, the cavity 402 includes openings 404 that align with various ports on a circuit board assembly positioned within the housing. Example ports include Ethernet ports and an electrical power connector. The openings 404 are located in a vertical wall of the cavity 402 that is substantially parallel to the central axis 106 of the housing 104 such that an angle between the central axis 106 and the vertical wall of the cavity 402 is less than approximately five degrees.
The footpad 212 is connected to the bottom exterior surface of the bottom housing member 110. The footpad 212 has a general C-shape such that the footpad 212 partially encircles the cavity 402 to opposing sides of the opening 222.
In addition, the bottom housing member 110 includes a cantilever member 406 formed within the bottom housing member 110 and connected to the bottom housing member 110 at a fulcrum. The cantilever member 406 is illustrated as dotted lines because in this bottom plan view 400, the cantilever member 406 is located behind the footpad 212. Accordingly, the cantilever member 406 may be hidden from view due to the positioning of the footpad 212. The cantilever member 406 is coplanar with the plane 210 defined by the bottom exterior surface of the bottom housing member 110. The cantilever member 406 is bendable, by a force applied to a free end of the cantilever member 406, to interface with a reset mechanism (described below in relation to FIG. 10D) on the circuit board assembly that is positioned within the housing 104. In aspects, the cantilever member 406 acts as a reset button that the user can press to reset the access point device 102. The footpad 212 includes a hole 408 aligned with the free end of the cantilever member 406. The hole 408 in the footpad 212 provides an indication to a user of a location of the reset button. The bottom plan view 400 includes a section line 5-5, which corresponds to the sectional view in FIG. 5, and a section line 6-6, which corresponds to a sectional view in FIG. 6.
FIG. 5 illustrates a sectional view 500 of the access point device 102 of FIG. 4 taken at the horizontal sectioning plane and in the direction indicated by section line 5-5. In this sectional view 500, the access point device 102 is upside down such that the top housing member 108 is shown in the lower region of the illustration and the bottom housing member 110 is shown in the upper region of the illustration. The access point device 102 includes various hardware components within the housing 104 in a compact assembly. For example, the access point device 102 includes an antenna carrier 502 supporting multiple antennas 504 attached thereto. The antenna carrier 502 is positioned within the housing 104 proximate (e.g., adjacent) to an inner surface of the top-end portion 204 of the top housing member 108. In addition, each of the antennas 504 is positioned proximate to an inner surface of the vertical wall 202, such that the antennas 504 are located within a tolerance distance of approximately two millimeters of the inner surface of the vertical wall 202.
The access point device also includes a heat sink 506 and a circuit board assembly 508. The heat sink 506 is positioned within the housing 104 proximate (e.g., adjacent) to, and abuts, the antenna carrier 502 such that the heat sink 506 is between the antenna carrier 502 and the circuit board assembly 508. The heat sink 506 may be formed from any suitable heat-conducting material, including die-cast aluminum.
The circuit board assembly 508 may include any suitable circuit board with connected electronic components in any suitable arrangement. One example includes a printed circuit board assembly (PCBA). The circuit board assembly 508 is positioned between the heat sink 506 and a heat shield 510. The heat shield 510 blocks heat transfer between opposing sides of the heat shield 510, e.g., in the direction of the central axis 106. Accordingly, the heat shield 510 shields heat, generated by the circuit board assembly 508, from transferring to the bottom housing member 110 of the access point device 102. This reduces the risk of thermal damage to cables or wires (not shown) that are connected to the access point device 102. In addition, the heat shield 510 is adjacent to the circuit board assembly 508 to shield the circuit board assembly 508 from electromagnetic interference (EMI) from the external wires or cables connected to the access point device 102, such as a power cable connected to an electrical power connector 512 (e.g., barrel jack) or a cable connected to an Ethernet port 514 of the access point device 102. The Ethernet ports 514 and the electrical power connector 512 are accessible via the exterior cavity 402 of the bottom housing member 110. The heat shield 510 is positioned between the circuit board assembly 508 and the bottom housing member 110.
FIG. 6 illustrates a sectional view 600 of the access point device 102 of FIG. 4 taken at the vertical sectioning plane and in the direction indicated by section line 6-6. In this sectional view 600, the access point device 102 is illustrated with the central axis 106 being horizontal such that the top housing member 108 is shown on the right and the bottom housing member 110 is shown on the left. As shown in FIG. 6, the Ethernet ports 514 extend substantially perpendicularly from the circuit board assembly 508 in the direction of the central axis 106 and toward the bottom housing member 110. The circuit board assembly 508 is positioned substantially perpendicular to the central axis 106. The heat shield 510 is positioned between a portion of the circuit board assembly 508 and the bottom housing member, such that the heat shield 510 is positioned between the exterior cavity 402 of the bottom housing member 110 and the portion of the circuit board assembly 508. The heat shield 510 is not, however, positioned between the Ethernet ports 514 and the bottom housing member 110. The heat shield 510 is shaped as a partial disk (e.g., approximately 60% to approximately 75% of a circular disk) to enable the Ethernet ports 514 to be positioned adjacent to the bottom housing member 110.
The top housing member 108, at the top-end portion 204 and the rounded edges 206, has a substantially uniform thickness. For example, inner and outer surfaces of the rounded edges 206 and the top-end portion 204 follow a substantially same curve. The vertical walls 202 of the top housing member 108, however, may not include a uniform thickness. This is due to the outer surface of the vertical wall 202 having a curve while the inner surface of the vertical wall 202 has a substantially zero-draft surface (e.g., straight surface with approximately zero taper). In aspects, the zero-draft surface is substantially parallel to the central axis 106 such that an angle between the zero-draft surface and the central axis is less than approximately five degrees. This zero-draft inner surface of the vertical wall 202 enables the components within the housing to be slidably removable for easy disassembly and/or slidably insertable for easy assembly. A more detailed view of this aspect is shown in FIG. 7.
FIG. 7 illustrates an enlarged view 700 of a portion of the rear sectional view 500 of FIG. 5, as indicated by a dashed circle in FIG. 5 and shows a connection point between top and bottom housing members of the housing. In the enlarged view 700, the top housing member 108 is connected to the bottom housing member 110. As described above, the vertical wall 202 of the top housing member 108 includes a varying (e.g., non-uniform) thickness based on a zero-draft inner surface 702 and a curved outer surface 704. The curved outer surface 704 provides a soft-looking surface for the exterior of the access point device 102 while the zero-draft inner surface 702 enables easy insertion or removal of internal components of the access point device 102. Also shown in the enlarged view 700 is a portion of the heat sink 506, which includes a protrusion 706 positioned within a recess 708 of the bottom housing member 110 for stability.
The housing 104 includes a vertical step member 710 that interfaces the bottom housing member 110 to the top housing member 108. As illustrated, the vertical step member 710 is inset toward the central axis of the housing 104 (horizontally offset from outer surfaces of the top and bottom housing members 108, 110) by a distance x 712 that is within a range of approximately 0.25 mm to approximately 1.0 mm. The vertical step member 710 has a height y 714 that is within a range of approximately 0.2 millimeters to approximately 2.0 millimeters. The vertical step member 710 creates a horizontal gap (e.g., the seam 112 from FIG. 1) between the top housing member 108 and the bottom housing member 110, with the gap including a height equal to the height y 714 of the vertical step member 710 and a depth equal to the distance x 712 that the vertical step member 710 is inset. The resulting gap has a height variance of less than 0.5 millimeters such that the gap is substantially uniform according to user perception. Without the vertical step member 710, the connection between the top housing member 108 and the bottom housing member 110 may create a seam that is more easily perceived by the human eye as being non-uniform in height. Accordingly, the gap created by the vertical step member 710 is less likely to be perceived, by the user, as not being uniform.
FIGS. 8A and 8B illustrate example exploded views 800 and 850, respectively, of the access point device. As generally shown in FIGS. 8A and 8B, the antenna carrier 502 is positioned between the top housing member 108 and a heat spreader 802. Fasteners 804 can be used to secure the antenna carrier 502 to the top housing member 108. Any suitable fastener may be used, such as screws, bolts, rivets, etc. The first heat spreader 802 is positioned between the antenna carrier 502 and the heat sink 506 to help spread heat across a surface of the heat sink 506. The heat sink 506 is positioned between the first heat spreader 802 and the circuit board assembly 508. Additional fasteners 806 can be used to secure the heat sink 506 to the antenna carrier 502. The first heat spreader 802 includes several holes through which protrusions on the heat sink 506 pass through to abut the antenna carrier 502. The additional fasteners 806 are positioned within holes in the protrusions and connect to the antenna carrier 502.
Thermal interface material 808 (e.g., thermal gel, thermal pads) are positioned between the heat sink 506 and the circuit board assembly 508. The circuit board assembly 508 is positioned between the heat sink 506 and a second heat spreader 810. The second heat spreader 810 abuts the heat shield 510 such that the second heat spreader 810 is positioned between the circuit board assembly 508 and the heat shield 510. The heat shield 510 abuts the bottom housing member 110. Fasteners 812 can be used to secure the circuit board assembly 508 to the heat sink 506. In addition, fasteners 814 can be used to secure the heat shield 510 to the circuit board assembly 508, or to secure the heat shield 510 to the heat sink 506 via holes in the circuit board assembly 508. Fastener 816 can be used to secure the bottom housing member 110 to the heat sink 506 via holes in the heat shield 510 and the circuit board assembly 508. The footpad 212 may be adhered to the bottom housing member 110 using any suitable adhesive. Also, a label 818 is adhered to the bottom of the bottom housing member 110, within the exterior cavity 402 shown in FIG. 4, to cover the fasteners 816 and the cantilever member 406.
The top housing member 108 also includes a recess 820 in the inner surface of the vertical wall. The top housing member 108 is translucent between the recess 820 and the outer surface of the top housing member 108. The top housing member 108 is formed of a partially translucent material (e.g., polymer or thermoplastic) such that light can pass through the material if the thickness of the material is below a threshold value. For example, a light source (e.g., light-emitting diode (LED)) connected to the circuit board assembly 508 can radiate light onto the inner surface of the top housing member 108. Based on the thickness of the top housing member 108 being below the threshold value at a location aligned with the LED, such as between the recess 820 and the outer surface of the vertical wall 202, the light passes through the top housing member 108 at that location. The light can correspond to an operating status of the access point device 102. Any suitable location on the top housing member 108 may be used to provide a status light, including a location on the top-end portion 204 of the top housing member 108. A light blocker 822 is positioned around the recess 820 to prevent the light from leaking through the top housing member 108 at locations or regions other than the intended location (e.g., the recess 820). Any suitable material can be used as the light blocker 822. One example light blocker 822 includes graphite (e.g., graphite adhesive) adhered to the top housing member 108. Another example light blocker 822 may be polyethylene terephthalate (PET) adhered to the top housing member.
FIG. 9 illustrates a front perspective view 900 of an antenna carrier of the access point device. The antenna carrier 502 has a generally disk-shaped body 902 having flanges 904 connected to the antennas 504. The antenna carrier 502 may be formed of any suitable non-conductive material, such as a polymer or thermoplastic. In this implementation, the antenna carrier 502 includes four flanges 904, each carrying a dipole (e.g., antenna 504) that can be implemented as a dual-band antenna. The antenna carrier 502 also includes a plurality of protrusions 906 (e.g., vertical beams) that abut the inner surface of the top-end portion 204 of the top housing member 108. The protrusions 906 define a position of the antennas 504 relative to the top-end portion 204 of the top housing member 108. Each antenna 504 includes a wired connection to the circuit board assembly 508 (shown in FIGS. 5, 6, 8A, and 8B) via a respective wire 908.
FIGS. 10A to 10D illustrate various views of an example circuit board assembly. FIG. 10A illustrates a perspective view 1000 of the circuit board assembly 508 from FIGS. 5, 6, 8A, and 8B and is oriented based on an axis 1002. The axis 1002 is aligned with a plane defined by a PCB 1004 of the circuit board assembly 508. FIG. 10B illustrates a top plan view 1010 of the circuit board assembly 508 from FIG. 10A. The circuit board assembly 508 includes a system-on-chip (SoC) 1012, a memory device 1014, a thread control block 1016, a wireless network module 1018, and a light-emitting diode (LED) 1020. The memory device 1014 can include any suitable memory, such as a double data rate memory. The wireless network module 1018 can include any suitable wireless network module, such as a 2.4 GHz Wi-Fi module. The LED 1020 corresponds to an operating status of the access point device 102. In aspects, the LED 1020 is aligned with the recess 820 in the top housing member 108 to radiate light through a translucent portion of the top housing member 108 that is between the recess 820 and the outer surface of the top housing member 108.
FIG. 10C illustrates a right elevational view 1030 of the circuit board assembly 508 from FIG. 10A. Here, the Ethernet port 514 is shown as extending perpendicularly from a plane defined by the PCB 1004 of the circuit board assembly 508. FIG. 10D illustrates a bottom plan view 1040 of the circuit board assembly 508 from FIG. 10A. The circuit board assembly 508 includes an additional wireless network module 1042, such as a 5 GHz Wi-Fi module. Using the wireless network module 1018 and the additional wireless network module 1042, the circuit board assembly 508 can be implemented as a dual-band router. In addition, the circuit board assembly 508 includes a tactile switch 1044 that is usable to toggle power to the electrical power connector 512. The circuit board assembly also includes a power management integrated circuit (PMIC) 1046 to control various components of the circuit board assembly 508, as well as components of the access point device 102. The arrangement of components on the circuit board assembly 508 illustrated in FIGS. 10A to 10D are shown as an example only and are not to be construed as limiting. The components of the circuit board assembly 508 can be implemented in any suitable configuration on the PCB 1004 for implementing aspects of the access point device 102.
Example Computing System
FIG. 11 is a block diagram illustrating an example mesh network device 1100 that can be implemented as any mesh network device in a mesh network in accordance with one or more aspects of the access point device described herein. The device 1100 can be integrated with electronic circuitry, microprocessors, memory, input output (I/O) logic control, communication interfaces and components, as well as other hardware, firmware, and/or software to implement the device in a mesh network. Further, the mesh network device 1100 can be implemented with various components, such as with any number and combination of different components as further described with reference to the example device shown in FIG. 12.
