EXHIBIT 6A1 1900 MHz TDMA RF POWER OUTPUT Para. 2.1033 (c)(6)(7), 2.1046 and 24.232 (a)(c) The RF maximum power measured at the output terminal (antenna connector) was 20 dBm at 1960 MHz. Note: The manufacturers rated voltage RBS is 110/220 VAC. The measurements were made per using the following equipment: Hewlett Packard Spectrum Analyzer Model 8563E Hewlett Packard Universal Counter Model 53131A Hewlett Packard AC Power Source Model 6813A Gigatronics Universal Power Meter Model 8651A Thermotron SM-8C Temperature Chamber APPLICANT:FCC ID NO: ERICSSON INCAXAKRC121107-1 © 2001 Ericsson Inc. Exhibit 6B1 1900 MHz TDMA MODULATION CHARACTERISTICS 2.1047(c)(13) The transceiver shall be capable of generating π/4 shifted differentially encoded quadrature phase shift keying signals. The transmitted signal is given by: S(t) = Σ g(t-nT) cos (φn) cos (ωct) - Σ g(t-nT) sin (φn) sin (ωct) where g(t) is the pulse shaping function that corresponds to a square root raised cosine baseband filter with roll off factor of 0.35, ωc is the radian carrier frequency, T is the symbol period, and φn is the absolute phase corresponding to the nth symbol interval. The symbol rate (1/T) is 24.3 k symbols /sec.} The modulation accuracy requirement is specified by setting limits on the RMS difference between the actual transmitted signal waveform and the ideal signal waveform. The ideal waveform is derived mathematically from the specification of modulation shown above. The specified requirement is error vector magnitude. For this measurement, frequency accuracy shall meet the requirements of Section 3.1 prior to measurement. The average carrier frequency error is the difference between the average carrier frequency of the actual transmitted waveform and the average signal waveform carrier frequency. The ideal modulation is defined above. The definition is such that, observing an ideal transmitter through an ideal root raised-cosine receiver filter at the correct sampling instants one symbol apart would result in the sequence of values given by: j{π/4+B(k)*π/2} S(k)=S(k-1)e where B(k) = 0,1,2,3 according to the following table: XkYkB(k) 000 011 112 103 In the forward channel, S(k) forms part of a continuous data stream. In the reverse channel, the transit bursts from the mobile are truncated by power up and down ramping. In this case, S(6) is the first sample that enters into demodulation, which yields the first two information bits by comparing S(6) with S(7). The last information bits lie in the comparison of S(162) and S(161). The ideal transmit and receive filters in cascade form a raised cosine Nyquist filter having an impulse response going through zero at symbol period intervals, so there is no inter-symbol interference at the ideal sampling points. The ideal signal sampler therefore, take on one of the eight values defined above, at the output of the receive filter. This section defines how the output signal from a transmitter is to be evaluated against the ideal signal. APPLICANT:FCC ID NO: ERICSSON INCAXAKRC121107-1 © 2001 Ericsson Inc. Let Z(k) be the complex vectors produced by observing the real transmitter through an ideal measuring receive filter at instants k, one symbol period apart. With S(k) defined as above, the transmitter is modeled as: k Z(k) = [C0 + C1 * [S(k)+E(k)]] * W where: k = n/24.3KHz dr=jda W = eaccounts for both a frequency offset giving “da” radians per symbol phase rotation and an amplitude changes of “dr” nepers per symbol: C0 is a constant origin offset representing quadrature modulator imbalance, C1 is a complex constant representing the arbitrary phase and output power of the transmitter, and E(k) is the residual vector error on sample S(k) The sum square vector error is then: k=MAXk=MAX | || |E(k)| || |2 |{[Z(k) * W -C0]/C1} -S(k)| k = MINk = MIN C0, C1 and W shall be chosen to minimize this expression and are then used to compute the individual vector errors E(k) on each symbol. The symbol timing phase of the receiver output samples used to compute the vector error shall also be chosen to give the lowest value. The values of MAX and MIN for the reverse channel (mobile station transmitter) are: MIN = 6 MAX= 162 The RMS vector error is then computed as the square root of the sum-square vector divided by the number of symbols in the slot, (157 in the reverse direction). Method of Measurement Connect the mobile station to the Standard Test Source and Modulation Accuracy Equipment. Modulate the Standard Test Source with pseudo-random Data Field bits. The mobile station shall transpond the Data Field bits using the TDMAON command. Use the Modulation Accuracy Measurement Equipment to measure the modulation accuracy of the mobile station. Minimum Standard The RMS vector error in any burst shall be less than 12.5%. APPLICANT:FCC ID NO: ERICSSON INCAXAKRC121107-1 © 2001 Ericsson Inc. Exhibit 6C1 1900 MHz: OCCUPIED BANDWIDTH Per 2.1049 (h) and 24.238 (a)(b)(c)(d) the exhibits presented show the modulation that has to exist in a 1900 MHz Cellular System. All the exhibits listed below are plots where the modulation condition is Psuedorandom Data (48.6 kb/s switched), operating in the TDMA mode. All plots were taken while transmitting at Power Level 0. Any frequency span not covered in the exhibits below was found to be unaffected by the transmitter/modulation.
