The intention is to make it possible to reuse parts of the system for developments concerning other systems and to perform independent improvements of the defined areas. COPMOPANP MSC rbs884macro SUP Transmission Network NINI Rx Rx Tx BS ETC STCRP GS RP CP #9/16 TRA RP NI T1 or E1 connection Figure 1RBS884 HW block diagram The RBS884 supports transcoder location in MSC only, which improves the transmission capacity by a factor three. The RBS884 is a fully multimode i.e. has all channel functions: - Digital Traffic Channel, DTC - Digital VERification, DVER - Control Channel, CC - Analog Voice Channel, AVC - Signal strength Receiver, SR - Digital Control CHannel, DCCH All carriers on a site are prepared to be TDMA frame and slot synchronized. The RBS884 platform utilizes equipment practice BYB 401 001. Description5 (36) 1996-08-02C8/1551-ANT 244 01 Uen Datum —DateRevDokumentnr —Document no E 3Features The RBS884 is designed for medium to high output power per carrier. 10 W transceivers or 30 W transceivers or 50 W transceivers can be selected. The RBS884 can be configured as an omni site, a two sector site or a three sector site. The RBS884 supports various cell patterns 7/21 and 4/12. The RBS884 highly scalable and its physical size depends on the maximum output power per carrier, the numbers of sectors and the number of carriers per sector. As an option the RBS884 can be equipped with a Tower Mounted Amplifier to balance the uplink RF-path and the downlink RF-path to increase coverage. 4Limitations The following functions and features are prepared in hardware, but will not have system support software-wise: - Analog verification (= AVC) in dual-mode verification - Control outputs - SW and HW information - Fault signal filtering - Pin pointing of faulty unit / Error log - RSSI calibration - RF test loop - Statistical supervision of DTC - APT-alarm for faulty RFTL - APT-alarm for faulty ALM (non-existant in this package) - Setting of MCU attenuation value per RCG (not needed on CMS88-markets) The RBS884 is not prepared for: - ADPCM/PCM transcoding in analog mode - BS power regulation dynamically (e.g. per time slot) The RBS884 also have the following limitations: - Cannot be used as a HUB to connect subordinated BSs to the MSC - Cannot be cascaded - Has no integrated power rectifiers - Has no unit generating the Air Frame Sync (AFS) Description6 (36) 1996-08-02C8/1551-ANT 244 01 Uen Datum —DateRevDokumentnr —Document no E 5Base station structure The base station consists of the following major functional parts: MSC rbs884macro1 ETB STR #9/16 EMRP TRX Rx Rx Tx PS MC COMB T S W COPMOPANP AC/DCBAT SUP DC distribution AC Mains Control paths Radio Frequency paths Voice & Data paths Figure 2The RBS884 structure COP - Control part Handles the communication with MSC and hosts the hardware for radio traffic control, statistics and control of MOP and ANP The COP is the SW-loadable part of the base station.

B5KKRC12110-21 DESCRIPTION 2.1033(c)(2)FCC Identifier:B5KKRC12110-21 This transmitter is only for use in the Domestic Cellular Radio Telephone Communica- tions Service, Subpart H of Part 22. The frequencies are generated using a phase- locked synthesizer. The synthesizer is locked to the in-coming sync signal from the PCM- link used for the system. (4)Type of Emission:40KOF1D 40KOF8W 30K0DXW 20KOFXW (5)Frequency range:869 to 894 MHz (6) Range of Operating Power: This transmitter is designated to supply 11 Watts of power at the antenna connector of the radio channel unit (TRX). 100 power levels are provided in 0.2 dB steps down to 110 milliwatts. (7)Maximum Power Rating: The maximum power rating under environmental supply voltage variations is equal to 11 watts plus the power level tolerance of + 1 dB. Therefore the maximum output power is 13.8 watts. (8)Final Amplifier Voltage and Current in normal operation (Rated power is for 1 device in the output stage). 0.11 Watts 11 Watts 24.5 V DC24.5 V DC 0.45 A DC2.4 A DC EXHIBIT12 Page12.2 APPLICANT: Ericsson Radio System ABFCC ID NO. B5KKRC12110-21 DESCRIPTION 2.1033(c)(10)Frequency Stabilizing Circuit Description The transmitter uses a phase-locked UHF VCO Operating between 761.07 MHz to 788.04 MHz. This signal is phase-locked to an internal 3.24 MHz reference oscillator frequency (RAREF) which in turn is divided down 6 times from the 19.44 MHz VCO in the digital block. The VCO is phase-locked to the incoming T- Link sync frequency of 2.048 MHz. RBS884 Macro and RBS882 Cassette The T-link is converted from a C-link in the DCON-board in the TCB-cabinet or in the cas- sette where the TRX:s are mounted. The C-link is phase-locked to the local PCM-link sync frequency of 1.544 MHz (or 2.048 MHz for non- US markets) in the CRI in the RBS884 Macro base station or the CRI in the RBS882 base station for cassettes. MINIMDBS The T-link is converted from a C-link in the MDCON-board in the MINIMDBS. The C-link is divided down 8 times from the local owen oscillator of 16.384 MHz in the PDB-board in the MINIMDBS. EXHIBIT12 Page12.3 APPLICANT: Ericsson Radio System ABFCC ID NO. B5KKRC12110-21 DESCRIPTION 2.1033(c)(10)Spurious and Harmonic Suppression Spurious and harmonic suppression is achieved by using a bandpass filter (N403 LX-stage) in the exciter amplifier and a passive bandpass filter connected to the TRX output. The output from the bandpass filter is connected to the applicable combiner system in the base station. The combiner system will connect all the TRX units in the RBS884 base station family to the same antenna output. The combiner system will connect all the cas- settes with TRX units, all existing TRM and DTRM units in the RBS882 base station family to the same antenna output. EXHIBIT12 Page12.4 APPLICANT: Ericsson Radio System ABFCC ID NO. B5KKRC12110-21 DESCRIPTION 2.1033(c)(10)Limiting Power The EMRPS function allows the RF power output to be set from 0 dB to – 20 dB attenuation in 0.2 dB steps from the MSC (Mobile Switching Center). The power levels can be in the range from a minimum of 110 milliwatts to a maximum Of 11 watts at the output of the TRX. The EMRPS supervises the feedback loop (RFF) from the Coupler stage to Linearization by checking the baseband signals. If the power output changes, the EMRPS will adjust the gain in the exciter amplifier. If some fault happens in the output power circuits, the EMRPS will compare the fault with prestored values and report the fault to the Switch via alarm codes in different levels. The highest alarm level is a serious fault and this alarm will get the EMRPS to shut down the output power stages without confirmation from the Switch. The EMRPS function will also control the RF power output according to the environment temperature. The power amplifier will not be able to get the supply current it need above 50 degrees C and below –5 degrees C. Then will the EMPRS shut down the power output since the unit is not able give a power out- put above –3 dB below set power level. EXHIBIT12 Page12.5 APPLICANT: Ericsson Radio System ABFCC ID NO. B5KKRC12110-21 DESCRIPTION 2.1033(c)(10)Digital Modulation The TRX is used both as voice channel and control channel in the RBS884 System. The modulation can be digital or analog. It can also be used as a data channel for Digital Packet Data. The DIGITAL modulation is limited in the waveform generator. The burst data from each time slot is formatted with syncwords and coded with a digital verification color code and user channel data. The formatted burst data are then converted to digital I and Q signals. These digital I and Q signals are then filtered in a square root raised cosine filter to form the correct modulation. The filtered signals are ten times oversampled and converted to analogue signals in a D/A- Converter. The modulation form is π/4-DQPSK for control and voice channel and GMSK for the CDPD channel. (10)Analog Modulation The TRX is used both as voice channel and control channel in the RBS884 System. The modulation can be digital or analog. It can also be used as a data channel for Digital Packet Data. The ANALOG modulation is limited in the wave- form generator. The speech or control data from the PCM-line is formatted as per IS-136 with syncwords and SAT. The formatted data are then converted to ”digital I and Q sig- nals” too form the correct frequency modula- tion. The signals are then ten times oversam- pled and converted to analogue signals in a D/A-Converter. The signals are converted in such a way that the output signal will format a Frequency Modulated signal.
