BlueT TCF Page 3 of 42 Date: 8/7/2001 1 Introduction The BlueT is an add-on device for the Palm500/505 that enables your PDA to communicate over Bluetooth with other Bluetooth devices. The BlueT uses pre-qualified components to implement lower layers of the Bluetooth stack, that is the radio, baseband, link manager, HCI, L2CAP, SDP and RFCOMM. It supports the Bluetooth profiles GAP, SDAP, SPP and DUN. These profiles are implemented by Tactel as software running on the BlueT unit. Tactel also presents software running on the Palm, which enables the Palm to control mobile phone functions over the Bluetooth link. 2 Architecture Application Program Interface (TTConnectLib API) VDRV, Dialup Networking Profile, incoming VDRV, Dialup Networking Profile, outgoing Radio (RF) Baseband (BB) Link Manager (LM) L2CAP RFCOMM SDP Tactel application implementing (DUN, SPP) Tactel protocol Inside Blue5 Inside Palm Bluetooth preferences screen VDRV, Serial Port Profile out AT-commands PPP TCP/IP Web-/WAP- browser Terminal programs/Games and other applications Prequalified Implemented by tactel Implemented in PalmOS VDRV, Serial Port Profile in Figure 2-1 The architecture of the BlueT BlueT-TCF, version 1.0 Page 4 of 42 Date: 8/21/2001 2.1 Radio The BlueT radio is implemented by the “Ericsson Bluetooth Radio ROK 101 002/1”. This component is a Bluetooth pre-qualified component. 2.2 Baseband and Link Manager The BlueT baseband and Link Manager are implemented by the Bluetooth pre- qualified Ericsson component “IrmaB HCI R1A” (BB Controller: ROP 101 1112/C P5A and LM FW: P11A). This component is unchanged and the functionality of the BlueT for those layers is the same as for the Bluetooth pre-qualified component. 2.3 L2CAP, SDP and RFCOMM The L2CAP, SDP and RFCOMM layers are implemented by the Bluetooth pre- qualified Ericsson component “Bluetooth HOST Stack CNX 901 184” compiled for the ARM7TDMI processor that is used inside the BlueT. The BlueT functionality of these layers is the same as for the Bluetooth pre-qualified component. 2.4 GAP, SDAP, SPP and DUN As seen in figure 2-1 (page 4) there is a Tactel application inside the BlueT. This application implements the supported profiles GAP, SDAP, SPP and DUN. It also handles the communication protocol with the software inside the Palm. This protocol is a packet-based protocol developed at Tactel to be optimized for the special environment. The protocol supports multiplexing of data flowing from other Bluetooth devices and simultaneous control of Bluetooth links. This enables several RFCOMM Bluetooth connections between two devices and in future versions easy support for multipoint connections. The protocol is designed so that most critical Bluetooth functions are implemented inside the BlueT. The electrical interface is RS232 with ESD protected drivers (±15KV Human Body model, ±15KV IEC1000-4- 2 Air Discharge, ±8KV IEC1000-4-2 Contact Discharge). 2.5 The applications inside the Palm The software written by Tactel inside the Palm consists of three layers. The lowest layer is the TTConnectLib, which is a Palm OS library (see appendix-API reference for TTConnectLib section 2.6). This library allows other applications to take advantage of Bluetooth. The library implements the Tactel protocol and also handles multiplexing with several applications. The next layer is “virtual drivers”. The following “virtual drivers” are implemented: Dialup networking, outgoing: This is used to establish a normal dial-up networking connection to a dial-up networking gateway. BlueT-TCF, version 1.0 Page 5 of 42 Date: 8/21/2001 Dialup networking, incoming: This is used to establish a dial-up networking connection to a dial-up networking gateway, when an incoming call is expected. Serial Port Profile Out: This is used to establish a Serial port profile connection when (Role Device A). Serial Port Profile In: This is used to wait for an incoming Serial Port Profile connection (Role Device B). These “virtual drivers” uses the TTConnectLib to establish connections with other Bluetooth devices. The “virtual drivers” is a Palm OS 3.3 and later concept that enables existing applications, like dialup networking, to work with Bluetooth without modifications. The third layer is the “Bluetooth preferences screen” which uses the TTConnectLib directly to search for other Bluetooth devices and configure the behavior (passkey mode, Bluetooth device address) of the virtual drivers. BlueT-TCF, version 1.0 Page 6 of 42 Date: 8/21/2001 3 Hardware Description 3.1 General Hardware Description The hardware is based on Ericsson Bluetooth chipset. The main components are the Bluetooth Radio (U2, see section 3.5 Component Placement-Top and section 3.7 Bill of Material), the Baseband processor (U1) and flash memory (U3). A reset component (U12) is used for reset the Bluetooth components when needed. The RS-232 Transceiver (U4) handles the connection to the Palm, i.e. translates the signal to meet the RS-232 standard. The power supply to the device is taken from the Palm and is regulated to 2.8 and 3.0V, this is done by the Dual LDO (U11). The 2.8V is used to power the Bluetooth components (U1, U2 and U3) and the switch regulator (U9) which provides the necessary voltage for the Blue LED (D2). All other components are supplied with the 3.0V voltage. The voltage is shut of when no RS232 signals are detected on the Palm connector (J1). The antenna is integrated with the PCB (U8).

RF exposure compliance issues: This device is only used with a handheld computer such as a palm pilot with no provision to connect to any other type of device. However, the maximum rf EIRP power output from the module is less than 1 milliwatt. If the entire rf power output were absorbed by 1 gram of tissue (not possible considering typical rf circuits), the SAR limit would still not be exceeded. Further, with a separation distance of 20 cm or greater, the MPE limits are well above the potential a 1 milliwatt device is capable of producing.

The PG from the direct sequence spreading caused by the access code in page and inquiry mode is found to be about 4 dB for three different access codes, with considerably different properties. Therefore, since Bluetooth in page and inquiry is considered as a hybrid system which is required to have a total PG of 17 dB, and the PG from the frequency hopping part is 15 dB, it is concluded that Ericsson’s receiver passes the test with a margin of about 2 dB.

Ericsson has performed such a measurement, and in this paper it is described how this measurement is performed together with the result showing that the PG from the DS part is about 4 dB. Consequently, it is concluded that Ericsson’s receiver has a PG from the DS part which exceeds the required 2 dB, and thus a total PG exceeding 17 dB, so that it indeed fulfils the by FCC imposed requirements. The remaining part of the paper is organized as follows. In Section 2, the CW- jamming method is recapitulated, and all parameter values that have to be determined for an measurement are given. Measurement method and results are given in Section 3. Finally, in Section 4, conclusions are drawn. 2 DESCRIPTION OF THE METHOD Referring to FCC §15.247 (e)(2), the processing gain may be determined as measured using the CW jamming margin method, which, for the sake of completeness, is repeated here: A signal generator is stepped in 50 kHz increments across the passband of the system, recording at each point the generator level required to produce the recommended Bit Error Rate (BER). This level is the jammer level. The output power of the intentional radiator is measured at the same point. The jammer to signal ratio (J/S) is then calculated, discarding the worst 20 % of the J/S data points. The lowest remaining J/S ratio is used to calculate the processing gain, as follows: Gp = S/N + Mj + Lsys, where Gp = the processing gain of the system, S/N = signal to noise ratio required for the chosen BER, Mj =J/S ratio, and Lsys = system losses. Note that total losses in a system, including intentional radiator and receiver, should be assumed to be no more than 2 dB. In Bluetooth, the despreading is accomplished by correlating the received bit stream with the bit pattern of the access code. Then the value of this correlation determines whether or not the access code should be considered as present. For Bluetooth, a “bit error” corresponds to that either the access code is present, but falsely rejected, or that the access code is absent but falsely accepted. The probability of the latter is negligible when compared to the former for any reasonable user scenario, and thus the false rejection ratio (FRR) is the figure of merit when evaluating the PG of the system. To reflect this, the CW jamming margin method, when applied to the Bluetooth system is interpreted as follows: REPORT4 (11) Uppgjord (även faktaansvarig om annan) - Prepared (also subject responsible if other)Nr - No. EMN/ERH/TA Frank Hooijschuur, ECS/UT/UV Leif Wilhelmsson EMN/ERH/TA-00:2502 Dokansv/Godk - Doc respons/ApprovedKontr – CheckedDatum - Date RevFile ECS/UM/VC Anders Svensson2000-06-21R1procgainresults.doc EN/FAD 109 251 R1B A signal generator is stepped in 50 kHz increments across the passband of the system, recording at each point the generator level required to produce the recommended false rejection ratio (FRR). This level is the jammer level. The output power of the intentional radiator is measured at the same point. The jammer to signal ratio (J/S) is then calculated, discarding the worst 20\% of the J/S data points. The lowest remaining J/S ratio is used to calculate the processing gain, as follows: Gp = S/N + Mj + Lsys, where Gp = the processing gain of the system, S/N = signal to noise ratio required for the chosen FRR, Mj =J/S ratio, and Lsys = system losses. Note that total losses in a system, including intentional radiator and receiver, should be assumed to be no more than 2 dB. It should here be noted that in order for the above test to be meaningful, the correct sampling time must have been found. If this is not the case, the BER would of course not be at an interesting level. For Bluetooth, the access code, whether in page, inquiry, or connection mode, is used to actually find the a suitable sampling point. 2.1 SYSTEM LOSSES In the calculation of Gp, it is stated that one may include a term to account for the system losses. For Bluetooth, the two major causes for system loss are by E…
