Type Acceptance Information for TS4000 Radio Modem with 3492 Transceiver
Proposed FCC ID JWFTS4000D
PURPOSE
The purpose of this document is to provide information in support of type acceptance testing and
report generation in pursuit of a Grant of Equipment Authorization under FCC Parts 15, 90 and
101 and Industry Canada RSS-119, RSS-210 and ICES-003 for Teledesign’s TS4000 Radio
Modem.
INTRODUCTION
The TS4000 is a high-speed radio modem that consists of a modem board, radio transceiver
board and metal enclosure. The radio transceiver board connects to the modem board with a
flexible printed circuit.
Radio Transceiver Board
The radio transceiver board for this application is an E.F. Johnson DL3492. This device is being
used without any modifications. The DL3492 has received FCC type acceptance with an FCC ID
of ATH2423492-001. All circuit descriptions and details for the radio transceiver can be found in
the type acceptance document for the DL3492. A copy of this has been included with this
application. The radio transceiver is available in a frequency range from 928-960 MHz and
includes a temperature stable reference oscillator with a frequency stability of ± 1.5 PPM.
Modem Board
The modem board provides the serial data interfaces that the user’s equipment interfaces to. The
modem board also controls the operation of the radio transceiver. This control includes
controlling the radio power and frequency and also controlling the modulation, data rate and
frequency deviation of the transmit signal. Note that it is this transmit signal that defines the
emission bandwidth and spectral efficiency.
Radio Flex Circuit
A flex circuit is used to interconnect the radio transceiver board to the modem board. This flex
circuit is also used to interconnect the serial port 2 connector to the modem board. The J11
interconnecting diagram included with the modem board schematic provides the specific
connections provided by the flex circuit for connecting the radio transceiver to the modem board.
Configuration Software
IBM compatible configuration software is used to control all aspects of configuration, tune up and
test of the TS4000 radio modem.

Type of Emissions:
25K0F1D - Part 101

12K5F1D - Part 101
11K2F1D - Part 90 (single bandwidth mode)
Emission Designator Calculations:
Modulation Types:
The TS4000 is designed to use three modulation types: 4 level FSK, GMSK with a BT=0.5 and
GMSK with a BT=0.3. The 4 level FSK modulation is provided to allow a high spectral efficiency
for a given channel bandwidth. The GMSK modulations are provided in order to be compatible
with other products and data communications standards.
Channel Bandwidths:
Our goal is to certify the TS4000 at two different channel bandwidths for Part 90: 20K0 and 11K2;
and two different channel bandwidths for Part 101: 25K0 and 12K5. This is to allow the TS4000 to
be setup for the most efficient operation for a given channel bandwidth that a user is licensed for.
4 Level FSK
25K0F1D and 20K0F1D:
Channel Baud Rate (B) = 32000 bps
Modulation Frequency (M) = B (1/8) = 4000 Hz
Peak Deviation = 6000 Hz
Bandwidth Calculation = 2 (D) + 2 (M)
Bandwidth Calculation = 2 (6000) + 2 (4000)
Bandwidth Calculation = 12000 + 8000
Bandwidth Calculation = 20000 or 20K0
