Operational Description

CCAR210R is the 802.11b/g/n MAC Wi-Fi and Bluetooth Low Energy BLE combo Module that acts as  a communication controller for users of a wireless device to connect to SMART DEVICE

Features

  • IEEE 802.11 b/g/n (2.4GHz, 1×1)
  •  20MHz/ 40MHz up to MCS7 supported
  •  Low power Tx/Rx for short range application supported
  •  Low power beacon listen mode
  •  Very low power suspends mode (DLPS)
  •  BLE
  •  High power mode (8dbm, share the same PA with Wi-Fi)
  •  Internal co-existence mechanism between Wi-Fi and BT to share the same antenna

Time base of the RF frequency
For IF and RF frequency, a crystal(40MHz) is a clock reference.

Synthesizer
Synthesizer inside Transceiver. Internal voltage controlled oscillator (VCO) provides the desired LO signal base on the phase-locked loop (PLL) with a relatively wide tuning range for this application. Internal fractional nPLL allows support for a wide range of reference clock frequencies

WIFI Transmission
Base-band data is modulated and upconverted to the 2.4GHz ISM band, respectively.
Base-band Processing (BBP) IC has DSSS (BPSK/QPSK/CCK) and OFDM
(BPSK/QPSK/16QAM/64QAM) modulation function, it provides transmission data rate are 1, 2, 5.5, 11Mbps on DSSS and 6, 12, 18, 24, 36, 48, 54 Mbps on OFDM. Digital data signal will be converted to analog (TX IQ) signals through DAC in BBP IC, TX IQ pass through to low pass filter. TX I/Q signal use direct conversion (zero-IF) architecture converter to generate carrier frequency signal. Transceiver IC and internal PA magnify output power.

WIFI Receiver
Reverse direction isolation of LNA inside Transceiver IC suppresses unwanted radiation. Then RF signal will be directly down to IF signal (RX IQ) and high frequency spurious emissions are suppressed by LPF. At last RX IQ signal will be demodulated digital data.

BLE
The RADIO contains a 2.4 GHz radio receiver and a 2.4 GHz radio transmitter that is compatible with 1M/2Mbps Bluetooth® low energy mode.

Notice FCC Statement

Approval Statement
CE Statement
Hereby, we declare that this device is in compliance with the essential requirements and other relevant provisions of directive 1999/5/EC.
FCC approval
This device complies with Part 15 of the FCC`s Rules. Operation is subject to the following two Conditions:

  1. This device may not cause harmful interference, and
  2. This device must accept any interference received, including interference that may cause undesirable operation.

To satisfy FCC exterior labeling requirements, the following text must be placed on the exterior of the end product. Contains Transmitter module FCC ID: A3LCCAR210R
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.
  •  The OEM integrator is responsible for ensuring the end-user has no manual instruction to remove or install module.
  •  The module is limited to installation in mobile or fixed applications.

IC approval
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions:

  • this device may not cause interference, and
  •  this device must accept any interference, including interference that may cause undesired operation of the device.

The host device must be labeled to display the Industry Canada certification number of the module.
Contains transmitter module IC:649E-CCAR210R

IMPORTANT NOTE

This device complies with FCC & IC radiation exposure limits set forth for an uncontrolled environment. This device should be installed and must not be co-located or operating in conjunction with any other antenna or transmitter. This device is intended only for OEM integrators under the following conditions:

  1. This module may not be co-located with any other transmitters or antennas.
  2. The antenna must be installed such that 20cm is maintained between the antenna and users.
    As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements with this module installed. In the event that these conditions cannot be met, then the FCC & IC authorizations are no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product including this module and obtaining separate FCC & IC authorizations.

User Information
Caution: Any changed or modifications not expressly approved by the party responsible for compliance could void the user`s authority to operate this equipment.
