Overview The A2500R24C and A2500R24A are surface mount modules with integrated crystal, internal voltage regulator, matching circuitry and filtering. The A2500R24A has an integral antenna, whereas the A2500R24C takes an external antenna through a U.FL connector (see Table 1). The modules operate in the global non-licensed 2.4GHz ISM/SRD frequency band. These radio modules are ideal for achieving low power wireless connectivity without having to deal with extensive RF, antenna design and regulatory compliance, allowing quick time to market. The modules are 100% tested to provide consistent performance. The A2500R24C and A2500R24A have received regulatory approvals for modular devices in the United States (FCC), Canada (IC) and Europe (ETSI). The modular approval allows the end user to place either an A2500R24A or an A2500R24C with an approved antenna inside a finished product without having to perform costly regulatory testing for an intentional radiator. Section 2 has information on the requirements for the end user/integrator must fulfill to use the modules without intentional radiator regulatory testing. The A2500R24C and A2500R24A are based on the CC2500 transceiver IC from Texas Instruments. All contr…

Typical Flow After initial setup of registers for desired behavior, the normal operation flow diagram is shown in Figure 4. In applications of infrequent data transmissions the transceiver would be in “sleep” mode to save power (400nA). From there it would be woken up and enter “idle” mode. As part of the wake up process the crystal oscillator is started (~250μs) and the digital microcontroller interface is powered up. Before transmit or receive the frequency synthesizer needs to be started (“FS_Wakeup”) and having been powered off (or idle for a while) the control loop of the VCO/PLL needs to be calibrated (“calibrate”). A data frame is loaded into the transmit FIFO and the “TX” mode is entered. The transceiver will transmit the data and enter “idle” mode after completion. When transmit is complete “RX” mode is entered to wait for the acknowledge frame. Once a frame is received the transceiver will again enter “idle”mode. If no acknowledge frame is received within a given timeout the data frame would be re- transmitted. If the acknowledge frame indicated that the data was received the next data frame would be transmitted. After the last data frame have successfully been transmitted the transceiver would again be put in “sleep” mode.

Attached is the authorization letter. 2. Integral Antenna (A2500R24A) The antenna is part of the module, and is printed on an inner layer as shown below (wavy line at top). That is why it is not visible in the pictures. The two pads on the top surface are actually test points, not an antenna connection point. It is matched to the 2.4 GHz operating band, and has a gain of 2 dBi. Please share this with the TCB reviewer and let me know if this answers the question. NOTE: We consider the antenna design 'proprietary', and request that pictures of it not be included in any documents open to the public. Attached please find the updated FCC Request for Confidentiality Letter. 3. Integral Antenna (A2500R24A) as shown in no. 2. Monopole and Patch Antenna Specifications (A2500R24C) are attached. 4. Attached revised user manual to address your questions. 5. The shape of plots inconsistence are caused by different detected mode, also the peak detection with max hold at 6dB BW but sample detection without max hold at 99% BW (IC only) during the test. Attached please find the revised report as one of the 99% plots on page 19 was incorrect. 6. Attached is the revised FCC Request for Modular Letter. Thanks, Claire Hoque -----Original Message----- From: Chris Harvey Sent: Tuesday, July 06, 2010 9:23 AM To: Thu Chan Cc: Chris Harvey; Claire Hoque; Lucy Tsai Subject: Anaren, Inc., FCC ID: X7J-A10030501, Assessment NO.: AN10T0569, Notice#1 Dear Claire and Thu, You are listed as the Technical Contact for the above referenced TCB application. The following items need to be resolved before the review can be continued: 1. The FCC's contact of record for Grantee Code X7J is Mark Burdick. The FCC requires that all documents required to be signed are signed by either the contact of record (Mark Burdick) or his authorized representative. The Letter of Authorization submitted in this application is signed by Kurt Richardson, who is not an authorized signatory for this application. 2. There are 2 versions of this device: Model A2500R24C with the U.fl connector and mode A2500R24A with a PCB antenna. The photographs of the A2500R24A seems to show a location for antenna connection, but does not seem to show the actual PCB antenna. Is the antenna part of the Module Circuit board or is it located on another PCB? 3. Please provide clear technical specifications and photographs for the 3 antennas included in this application: 2dBi PCB, 3dBi monopole and 5dBi patch antennas. 4. The Users Manual exhibit states 2400.999786 MHz low channel and 2482.539 MHz high channel for the US & Canada for both 2FSK and MSK modulations, but the application has been submitted for only 2401.3-2480.4 MHz for 2FSK and 2401.8 - 2480.3 MHz for MSK operations. Why are non-approved channels listed in the manual as being USA and Canada compliant? If the module is capable of operation outside of the approved channels, how is the end user prevented from using those non-approved channels? Please either re-test for all channels or revise the manual to clearly indicate the available channels. 5. Please confirm that the plots for 6dB BW and 99% BW are correct and labeled correctly. It appears that the 2FSK plots and the MSK plots may have gotten mixed as the 6dB BW plots and the 99% BW plots do not appear similar for the same modulation. 6. The Modular Approval request exhibit shows an incorrect FCC ID number for this application. Please submit a corrected exhibit. The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information within 30 days of the original e-mail date may result in application dismissal and forfeiture of the filing fee. Also, please note that partial responses increase processing time and should not be submitted. Any questions about the content of this correspondence should be directed to the e-mail address listed below the name of the sender. Best regards, Chris Harvey [email protected]

Simple certification labeling replaces testing. 1.4. Theory of Operation The A2500R24C and A2500R24A are for low power wireless applications in the 2400MHz to 2483.5MHz global ISM/SRD band. The devices can be used to implement a variety of networks, including; point to point, point to multipoint, peer to peer and mesh networks The A2500R24C and A2500R24A both interface to an application microcontroller via SPI bus. Physical and MAC layer functionality are accessed via the SPI bus, through addressable registers as well as execution commands. Data received or to be transmitted are also accessed through the SPI bus and are implemented as a FIFO register (64 bytes each for Tx and Rx). To transmit, a frame of data is placed in the FIFO, this may include a destination address. A transmit command is given, which will transmit the data according to the initial setup of the registers. To receive data a receive command is given, which will listen for a transmission and when one occurs put the received frame in the FIFO. When neither transmit or receive is required the device can enter either an Idle mode, from which it can quickly re-enter receive or transmit mode or it can enter a low power sleep mode, from which a crystal startup is also required prior to transmit or receive operation. Below a block diagram is given for each of the A2500R24C and A2500R24A modules. • Antenna o The antenna couples energy between the air and the module. For applications where installations are done by an end user (non-professional), an omni-directional antenna pattern is desired, such that the application will work equally well in any direction. Similarly for peer to peer or point to multipoint application an omni-directional pattern is desired such that all nodes have a fair chance of communicating. The A2500R24A module has an integral antenna that is near omni-directional, whereas the A2500R24C has approved antenna options ranging from near omni-directional to shaped front/back patterns (useful for inline, professional installations). Note that the end radiation pattern Anaren AIR Module, Users Manual 4/21, 6/28/2010:11:16 AM depend not only on the antenna, but also the ground plane, enclosure and installation environment. • Filtering o Filtering removes spurious signals to comply with regulatory intentional radiator requirements. • Matching o The matching provides the correct loading of the transmit amplifier to achieve the highest output power as well as the correct loading for the receive LNA to achieve the best sensitivity. • Physical o The physical layer provides conversions between data, symbol and RF signal. • MAC o The MAC layer is part of the Logical Link Layer and provides frame handling, addressing and medium access services. • Microcontroller Interface o The microcontroller interface exposes registers and commands for the physical and MAC layers to a microcontroller. • Power Management o Power management ensures a stable supply for the internal functions as well as providing means for a low power sleep mode, in which most of the transceiver is power off.
