System Integration

System Integration Block Diagram.

As shown in the block diagram, the modular nature of the MIMO radio transceivers allow for accelerated development of the wireless modem. Any embedded Single Board Computer with standard miniPCI-Express interface is required. The Linux distribution OpenWRT has evolved over time and provides advanced features in a wireless router. It is a stable distribution and many OEMs are using OpenWRT as a starting point and customize further for their application. The distribution includes the ath10k driver to interface with the MIMO transceivers. Both OpenWRT and open source drivers (ath9k and ath10k) have extensive online documentation available. User group forums also provide responsive technical support.

FCC Regulatory Compliance:
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

•  this device may not cause harmful interference, and
•  this device must accept any interference received, including interference that may cause undesired operation.
  Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate
  radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
• However, there is no guarantee that interference will not occur in a particular installation.
• If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
• Warning: changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
• If power exceeds the limit and the distance(Over 20cm distance in actual use between the device and user) is compliance with the requirement

RF Exposure Compliance:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator and any part of your body.

Notice to OEM integrator

• If the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. The end product shall haves the words “Contains Transmitter Module FCC ID: 2AG87ACM-DB-3-R2”.
• The device must be professionally installed.
• The intended use is generally not for the general public. It is generally for industry/commercial use.
• The connector is within the transmitter enclosure and can only be accessed by disassembly of the transmitter that is not normally required. The user has no access to the connector.
• Installation must be controlled. Installation requires special training.
• Any company of the host device which installs this modular with unlimited modular approval should perform the test of radiated & conducted emission and spurious emission, etc. according to FCC part 15C: 15.247 and15.207, 15B Class B and Part 15 Subpart E Section 15.407 requirement, only if the tests result comply with FCC part 15C: 15.247 and15.207, 15B Class B and Part 15 Subpart E Section 15.407 requirement, then the host can be sole legally.
  When the module is installed inside another device, the user manual of the hose contain below
• This device may not cause harmful interference.
•  This device must accept any interference received, including interference that may cause undesired operation
