APPLICANT:Exhibit 12 Ericsson Radio Systems ABOperational Description FCC ID NO. B5KKRC16145 EXHIBIT LIST Exhibit No.Paragraph. Ref.Description 122.1033 (c) Technical Description of RBS 2401 APPLICANT:Exhibit 12 Ericsson Radio Systems ABFCC ID NO. B5KKRC16145 DESCRIPTION 2.1033(c) (1)Manufacturer:Ericsson Radio Systems AB Torshamnsgatan 21-23 S-164 80 Stockholm Applicant:Ericsson Microwave Systems AB Bergfotsgatan 2 S-431 84 Gothenburg The equipment is manufactured with the following possible variations: - It's fitted with two transceivers in the same enclosure. - It can be fitted with one of two variants of the frequency reference, one which locks it’s frequency to the incoming PCM-signal, or one which has an internal, oven-controlled reference oscillator. - It can be fitted with one of two variants of communication hardware for the PCM-connection. One for the E1 standard (2.048 Mbps), or one for the T1 standard (1.544 Mbps). - The encryption is realized with either algorithm A5/1 or A5/2. The transceiver is prepared for quantity production. This transmitter is a synthesized transmitter operating in the frequency band of 1930 to 1990 MHz. There are 299 Channels available with a channel spacing of 200 kHz. This is a constant envelop transmitter using Gaussian Minimum Shift Keying (GMSK) with a BT product of 0.3. The transmitter is capable of operation in a TDMA (Time Division Multiple Access) system. For each channel there are timeslots available, each containing digital speech or data. The transmitter is designed for use in Personal Communications Services systems. (4)Type of Emission: 305KGXW (5)Frequency range: 1930 to 1990 MHz (6)Range of Operating Power: This transmitter is designed to supply a maximum nominal power level of 22 dBm of power at the antenna connector. The power level can be set at 8 power levels, each with a 2 dB increment. The power levels are labeled P(0) to P(7) where P(0) is the highest power level. (7)Maximum Power Rating: The maximum power rating under environmental and supply voltage variations is equal to 22 dBm plus a power level tolerance of +/- 2 dB. Therefore the maximum output power is 24 dBm at each antenna connector of the radio base station. (8)Final Amplifier Voltage and Current in normal operation per transceiver. P(0) P(7) Collector Voltage 12 Volt DC 12 Volt DC Collector Current 0.2 Amps DC 0.1 Amps DC APPLICANT:Exhibit 12 Ericsson Radio Systems ABFCC ID NO. B5KKRC16131 CIRCUIT AND DEVICE DESCRIPTIONS (10)Frequency Stabilizing Circuit Description The transmitter contains three synthesized oscillators. One gives a 160 MHz signal to the I/Q modulator. The two other generate a 1770 to 1830 MHz signal to the mixer where the modulated signal is upconverted to the transmit frequency. Two oscillators are needed in frequency hopping mode, one is retuning while the other is active. All three synthesized oscillators have as reference a 13 MHz sinusoidal signal generated in a phase locked loop (PLL) in the TRX. The PLL is locked to a 270.8 kHz signal which is generated and distributed to all TRX in the basestation by the DXB (Distribution Switch Board). The frequency reference from DXB is generated in a voltage controlled oscillator whichis frequency locked to a long term stable oven heated oscillator or as an option to the incoming PCM-link frequency. Attenuation of Spurious Emissions Spurious and harmonic suppression is achieved by using two separate bandpass filters (Z3 & Z4) of ceramic type in the exciter. A filter module at the output works like a harmonic filter. In addition to these filters, the output signal passes the CDU (Combining and Distributing Unit) which contains of two cavity band pass filter and a hybrid-combiner. Limiting Power The TRX measures the output power at its output connector via a RF-detector and the detected value is used by the power loop control block to steer two variable gain amplifiers between the modulator and the power amplifier. (13)Digital Modulation The modulation description is given in PN3389 Air Interface: Volume 1 section 4. PN3389 Air Interface: Volume 1 section 4.1 to 4.1.3 PN3389 Air Interface: Volume 1 section 4.1.4 to 4.1.6 APPLICANT:Exhibit 12 Ericsson Radio Systems ABFCC ID NO. B5KKRC16131 CIRCUIT AND DEVICE DESCRIPTIONS PN3389 Air Interface: Volume 1JTC(AIR)94.10.31-231R5 4.Modulation This chapter defines the theoretical requirements of the modulator, inclusive of the differential encoder. The modulator receives the bits from the encryption unit and produces an RF modulated signal. The information bits are first differentially encoded and then passed to the modulator. The modulation is GMSK (Gaussian Minimum Shift Keying) with a BT product of 0.3. 4.1Modulation Format 4.1.1Modulating Bit Rate The modulating bit rate is 1/T = 1625/6 kb/s (approximately 270.833 kb/s). 4.1.2Start And Stop Of The Burst The bits contained within a burst are defined in chapter 2. For the purpose of the modulator specification that follows, the bits entering the differential encoder prior to the first bit of the burst and following the last bit of the burst are consecutive logical ones and are denoted by the term dummy bits which define the start and end points of the useful and active parts of the burst as shown in Figure 4.1. The actual state of these bits is left to the manufacturer’s implementation subject to the requirement that all performance specifications of this volume are met. Nothing is specified about the actual phase of the modulator output signal outside of the useful part of the burst. Figure 4.1 depicts the relationship between the active and useful part of the burst, the tail bits and dummy bits for a normal burst. The useful part of the burst lasts for 147 modulating bits.
