Hi Mike, After our review of this application we have identified the following issues, 1. Please clarify the intention of this application. Is the application for the LAN access point (Model RBTRC-MZ) with the external antenna ( RBTBH-IA) or for the RBTBH-R2W radio card with the external antenna to be used in different hosts. The latter requires a modular ( or limited modular) certification application. This application is for the LAN card only. 2. Assuming the application is for the host LAN access point as a whole, the label must be placed outside the chassis. A placement photo of this label will be needed and it should also include the compliance statements (15.19(a)(3)) on it. Please supply a revised label with placement photo. n/a 3. The antenna specification document for the external antenna, does not address the connector type on it. Please supply closer views of the MMCX antenna connector on the transmitter board and the antenna cable. Antenna connector specs attached. 4. Please supply the test setup photos. Attached. 5. Please clarify if radiated emissions tests were done with the external antenna attached/detached or both. Please also clarify which configuration (external antenna attached/detached) produces more antenna gain to the radio. Radiated emissions was tested with the range extender both on and off. The internal antennas have higher gain than the range extender. 6. Have all the modulations of 802.11a/b/g been investigated for both radiated and conducted (antenna terminal) tests for testing? Are the results in the report the worst cases recorded? Please clarify.CCK and OFDM are the available modulations for the 2.4GHz range, and only OFDM is available for the 5GHz range. All modulation types were measured and the worst case data reported. 7. Please specify the test method used for peak output power measurements at the antenna terminal during 802.11b/g configuration. (Pg 8 of the report) The output power was measured with the HP 435B power meter with the radio operating in CW mode. 8. The plot on Pg 11 of the report appears to be a duplicate of the 3rd plot on Pg 10. Please supply high band-edge (Ch11, CCK 1MBps) plot again. Updated report attached. 9. Please supply a channel allocation list from the grantee for the 802.11a configuration. The report mentions some channel changes on some of the data tables that were realized later during the test. Highest and lowest operating channel frequencies must be specified and the grantee must declare that the operation will be restricted within those channels only.Channel allocation list has been added to revised Install guide. (attached) 10. For radiated spurious emissions tests of both 802.11a and b/g configurations, have emissions been checked when the radios are transmitting on at least 3 different channels (top, middle, bottom). Please clarify. After a prescan, spurious emissions were checked only on the worst case channel. This data has been provided. 11. Have EIRP levels of the 802.11a configuration complied with the limits of 15.407(b)(1)-(4)? Please clarify. Yes. The section U-NII - Conducted Band Edges on page 22 addresses this. 12. Has the external antenna position been adjusted to maximize emissions during radiated spurious tests? Yes. This is addressed in the Test Methodology section. 13. The grantee must clarify how the device complies with 15.407(c). Description of compliance to 15.407c attached. 14. The grantee must also clarify how the device will meet the internal antenna requirement for 5.15-5.25 GHz band operation as required by 15.407(d) and how this will be ensured when marketed to the users. Description of compliance to 15.407d attached. 15. The user manual must warn the users about the indoor use requirement of the device within 5.15-5.25GHz band. Please point out the section in the manual where this was addressed. Statement placed below 802.11a channel allocation table in revised install guide. (attached) 16. The document supplied as "Manual 1" suggests portable installation conditions for RF exposure on Pg 3. These statements must be removed as they require SAR evaluations. The installation conditions with both the external and the internal antenna configurations must meet the 20cm requirement and the warning must be very clear on this in that section. SAR statements removed and 20cm warning for both integral and external antenna in revised install guide.(attached) 17. The grantee must clarify how the co-location issues will be handled within 2 radios. Pg 5 of the same document suggests that if one radio is configured for 802.11a and the other for b/g, then external antenna use is not needed. In this case the radiating structures will be closer than 20cm and co-located exposure calculations will be necessary. However if there's always and extender with one of the radios, then 20cm separation can be demonstrated. Please clarify with what kind of options (radio card - antenna combinations) is device planned to be marketed. This application is for the card only. 18. The same section of the document (Pg 5) also suggests that 2 radios of the same type can be used with an extender on one of them. For this case it must be justified how the EMC test data for one radio will be representative of both operating at the same time at the same frequency. Clarifications will be needed. Points 16, 17 and 18 will need clear instructions in the manual to avoid any confusion. This application is for the card only. 19. The RF exposure calculations must address both the "internal antenna only" and "external antenna attached" cases for both 802.11a and b/g configurations. Please revise the calculations. A note has been added to the attached MPE Calculations stating that the highest antenna gain is used in the calculation. Best Regards, Yunus Faziloglu Reviewing Engineer Curtis-Straus TCB

The product is the Enterasys RoamAbout 802.11a/b/g wireless radio card (Model RBTBH-R2W) with range extender (non- amplified external antenna, Model RBTBH-IA) as installed in the RoamAbout wireless LAN access point (Model RBTRC-MZ). The access point is populated with two of these wireless PCMCIA LAN cards which have the ability to operate in both the 802.11a range (see table below) as well as the 802.11b/g range (2400-2483.5MHz). When the access point is running with two cards, each card operates in a single range different from the other. U-NII Bands Frequency Range (GHz) Usage Limitations 5.15-5.25 Indoor use; no range extender 5.25-5.35 N/A 5.725-5.825 N/A One or the other of the cards is always populated with the range extender, which is effective in both the 2.4GHz, and 5GHz frequency ranges. The maximum directional gain of the internal antenna is 3dBi in the 2.4GHz range, and 5dBi in the 5GHz range. The directional gain of the range extender is <0.75dBi in the 2.4GHz range, and <4dBi in the 5GHz range. Test Methodology Radiated emissions testing is performed according to the procedures specified in ANSI C63.4 (2003). FCC’s “Guidance on Measurements for Digital Transmission Systems Section 15.247” and “Guidelines for Assessing Unlicensed National Information Infrastructure (U-NII) Devices – Part 15, Subpart E” were followed for testing as well. Radiated emissions were maximized by rotating the EUT (including the range extender) around three orthogonal axes as well as varying the receiving antenna’s height and polarity. The internal antenna cannot be maximized separately. Frequency range investigated: 0.15MHz – 40GHz Measurement distance: 0.15 - 30MHz Conducted 30MHz – 18GHz 3m 18 – 26.5GHz 1m 26.5 – 40GHz 0.1m AC Li…

9/28/2004 Agere Systems (Proprietary) 1 of 2 Subject: FCC 15-407c : Automatic Discontinuation of Transmission Date: September 24, 2004 Version 1.00 Author: Jim Archibald TRANSMIT DISCONTINUATION: FCC 15.407c guidelines require that a Wireless LAN device automatically discontinue transmission when there is no information to send or if there is an operational failure. The text of the FCC requirement is as follows: IMPLEMENTATION: Figure 1 shows the block diagram of a Wireless LAN card based on the Agere chipset. This chipset includes, from left to right, the WL60040 Media Access Controller (MAC), the WL64040 Baseband Processor, the WL54040 RF transceiver and the WL54240 Power Amplifier. Agere’s solution follows the normal 802.11 MAC protocols that dictate how and when a Wireless LAN card gets access and transmits over the medium. Agere complies with the Distributed Coordination Function (DCF) architecture and the CSMA/CA (Carrier Sense Multiple Access / Collision Avoidance) scheme that permits Wireless LAN cards to access the airwaves in an orderly fashion and transmit only when the have a valid transmit frame to send. In addition to the normal MAC protocols there is also a mechanism in place whereby the WL64040 Baseband Processor is effectively muted unless the TXE (Transmit Enable) signal from the MAC is asserted. The TXE signal is shown in Figure 1 as an output going from the WL60040 MAC to the Baseband. The Baseband will not transmit unless the TXE signal from the MAC is asserted. If the TXE is de-asserted for any reason before the end of the current transmitting frame, the Baseband will abort the transmission. Hence, the control for transmission lies in the MAC via the TXE signal. This ensures that there are no random transmits. 09/28/04 Page 2 of 2 Figure 1. Block diagram of the Agere Wireless LAN system including TXE signal.

9/28/2004 Agere Systems (Proprietary) 1 of 2 Subject: FCC 15-407d : Disabling Use of 5.15-5.25 GHz band when connecting external antenna. Date: September 23, 2004 Version 1.01 Author: Jim Archibald FEATURE DESCRIPTION: The following describes the method for disabling the use of the 802.11a/h frequencies in the 5.150 to 5.250 GHz band when an external antenna is connected. FCC specification 15.407d states that “Any U-NII device that operates in the 5.15-5.25 GHz band shall use a transmitting antenna that is an integral part of the device.” The Agere-based Wireless LAN PC- Card (reference design model 8u580) adheres to the above requirement as is described below. The model 8u580 PC-Card features an external antenna connector switch made by Aliner Enterprises (model 23-302B). The antenna connector is shown as connector J600 in Figure 1. The Aliner receptacle will accept a male connector that runs to an external 5GHz range extending antenna. When the external antenna is inserted into jack J600 then pins 1 and 2 of J600 are disconnected from each other. When this occurs, the 3.3V DC voltage provided by the DIVERSITY digital signal becomes open across J600 pins 1 and 2. This results in the signal EXTANTSEN being pulled low. The EXTANTSEN output signal runs to the PHY STATUS digital input signal on pin K2 of the Agere WL60040 Media Access Controller (MAC) IC. The firmware running in the Agere WL60040 MAC device senses the state of PHY STATUS input pin. If PHY STATUS is LOW then the logic implemented in the MAC firmware disables any 802.11 transmission in the 5.15-5.25 GHz U-NII band. 09/28/04 Page 2 of 2 Figure 1. Schematic diagram of logic used in 8u580 PC-Card to disable transmission in the 5.15- 5.25 GHz spectrum.
