GENERAL DESCRIPTIONS
2.1 Multi-band :
CMD-J16 support E-GSM 900 and DCS 1800 multi-band functionality.
For the use in Europe and in other countries worldwide, ETSI has specified GSM standards into two frequency
bands. That is the 900-MHz and 1800-MHz band and is usually referred to as GSM900 and GSM1800 (formerly
DCS1800).
While the 900-MHz band has 124 channels (extended version: 175), the 1800-MHz band with its 375 channels
provides a three-times higher capacity. Not only as a result of this large range of channels but also due to the low
transmission power and the transmission distance, GSM1800 supports a higher quantity of RF-channels.
The Dual band technology enables a network operator with spectrum at both 900MHz and 1800MHz to support the
seamless use of dual band handsets across both frequencies. By supporting seamless handovers between
900MHz and 1800MHz, Dual band networks can provide major benefits in terms of capacity enhancement and
revenue optimisation through the introduction of new services.
The CMD-J16 is a phase II, GSM 900 class 4, DCS 1800 class 1 mobile phone.
The nominal maximum output power for GSM 900 is 2W, for DCS 1800 1W .
It supports the extra functionality required for multi-band mobile stations: Inter-band/”seamless” hand-over,
channel assignment, cell selection and re-selection, all between both bands within a Public Land Mobile Network.
The manual and automatic PLMN selection in both bands is given.
The user does not need any special action to use the multi-band functionality of the phone.
Users are able to manually roam between PLMN’s operating in GSM 900 and DCS 1800 bands.
E-GSM
With the further development of the GSM standard, an additional range of frequencies has been made available to
the “Global system for mobile communications”. For each of the two duplex frequency ranges, one for the forward
direction and one for the reverse direction, additional 10 MHz have been added to the bottom end of the bands,
extending the frequency range to 50 further channels.
The mobile station transmits in the 880- to 915 MHz range, and the base station transmits in the 925- to 960 MHz
range. A duplex spacing of 45 MHz is used, the base station always transmits on the high side of the duplex
frequency pair.
The numbering for these additional channels is from 974 to 1023. This is done to avoid assigning one channel
number twice within the same standard.
Compared to the primary GSM system, Channel number 0 is used in the extended GSM system, since it does not
make sense to reserve it at a guard band within the E-GSM bands. Now, the lowest channel, number 974 (880.0
MHz), serves as the guard band between GSM and other services on lower frequencies.
DCS 1800
DCS-1800 uses the frequency ranges of 1710 to 1785 MHz in the uplink direction, and 1805 to 1880 MHz in the
downlink direction.
From these figures it follows that the duplex spacing is 95 MHz with 374 channels with bandwidths of 200 kHz
each.
The channels are numbered from 512 to 885 in order to distinguish them from the channels in the primary and
extended GSM frequency bands.

2.2 Radio Frequency Power Levels:
Between the DCS 1800 and both GSM Systems are differences regarding the power level. DCS 1800 basically
needs lower power levels. If the performance of a MS for GSM system was certified of 2W (Power Class 4), then in
the DCS-1800 system it is only 1W (Power Class 1). There are also reduced BTS power levels due to microcell
applications, which means instead of the 40W (Power Class 4) in the GSM system DCS 1800 needs only 20W
(Power Class 1).

2.3 Speech Codec
The CMD-J16 supports the following speech codecs.
Full Rate (FR) Codec
•
Half Rate (HR) Codec
•
Enhanced Full Rate (EFR) Codec
•
The speech codec forms the human voice into a digital signal, which is sent in the GSM network.
The GSM system currently has three different speech codec standards.
At first, the Full Rate (FR) Codec was introduced. With new requirements concerning speech quality and
availability of radio channel resources two further standards were introduced, the Half Rate (HR) Codec and the
Enhanced Full Rate (EFR) Codec. The Half Rate (HR) Codec requires only half the channel capacity of a Full Rate
(FR) Channel. The Enhanced Full Rate (EFR) Codec requires the same radio channel resources as a Full Rate
(FR) Codec but offers Fixed Line quality with superior vocal clarity.

2.5 Battery Charging
There is no charging circuitry in the battery pack. The CMD-J5/J16 has complete charger function internally.
The telephone can be charged only with the battery connected the phone. This situation can be sub-divided into
two situations: the phone is on or off. It can be charged with the AC Adapter, Travel Charger or Cigar Lighter
Charger.
The battery symbol is used to indicate the charging, and to indicate when the battery is fully charged. This is done
using the following sequence of icons:
The uncharged segments of the battery are moving in a right to left manner until the charging stops. The
sequences for each charging level is repeated until the battery is charged to that level.
When the charging sequence is finished the flashing of the battery level sign stops.
The phone shows the full-battery icon.
2.6 Battery Safety
The battery pack contains a single Li-ion cell, a safety circuitry and, in addition, a microprocessor unit which
manages RTC information by reading out the binary counter value in the microprocessor. The charging circuitry
and the safety circuitry together guarantee a double fail-safe battery pack. This means that each component can
be either short or open and still all the safety requirements will not be violated.
The safety concept protects against:
Over voltage:
when Vbat falls below (4.025V - 4.125V).
Under voltage:
Charging is still possible.
Current fuse:
the device from explosion and fire with melting. The fuse melts 10A during 1 second.
The charging is stopped when Battery Voltage (Vbat) reaches 4.25V- 4.3V. The charging resumes
When the cell voltage drops below 2.242V – 2.358V the cell is disconnected for discharging.
Finally, if all protection functions are out of order due to abnormal condition, the current fuse protects
2.7 Battery Capacity:
Standard Battery 640mAh typical Li-ion QN-J5BPS
Extended Battery 920mAh typical Li-ion QN-J5BPE
The phone can be charged even during making phone calls.
However, the shortest charging time will be reached when the phone is switched off.
