New Nokia phone using ball grid array chips vice the antique quad flat packs in previous phones.
Nice looking phone, but AMPS/TDMA.

1. There is a mistake in the test report. The power output ratings mentioned in
the correspondence are referring to radiated power output, but the correct
readings are 400 mW (26.0 dBm) ERP for AMPS and 917 mW (29.6 dBm)
ERP for TDMA. Corresponding conducted power output ratings in the test
reports are 25.78 dBm (AMPS) and 27.18 dBm (TDMA). We are sorry for the
inconvenience.
2. The reason for this is that the test equipment the lab is using for radiated
power measurement is not capable for measuring averaged TDMA bursts.
Therefore we have to provide the peak reading for TDMA mode, which is
around 2.5 dB higher compared to averaged reading. Conducted power is
measured using duty cycle, which takes into account these characteristics of
the modulation method. We verified this by using power meter also for
measuring radiated power output at the same time and the difference between
AMPS and TDMA mode was almost the same than in conducted
measurements. However, these records cannot be used in official report.
3. We are aware of the problems caused by positioning the antenna too close of
device holder, and we have done our best in positioning the device in such
way that these effects are minimized. We use equipment shown in Figure 1 to
provide a standard position for all our phones.
