1.0 Overview
Teletronics' advanced WINC 2400C 1 modem is a versatile wireless synchronous modem that compatibly
interfaces with a variety of external synchronous data devices, including multiplexers, routers, bridges,
PBXs, frame relays, etc. Acting as “wireless airports”, the WINC 2400C’s transmit and receive data
information for the synchronous data devices located in separated locations without cables and expensive
network operating system. The modem operates at very low power in the FCC designated ISM
(Instrument, Scientific and Medical) frequency band between 2400 and 2483 MHz and user requires no
license to operate. Using state-of-the-art spread spectrum technology, the WINC 2400C offers point-to-
point linkage and point-to-multipoint broadcasting data communications function. Typical applications
include multichannels of voice, facsimile, and data up to 128 Kbps.
2.0 Technical Information
The WINC 2400C transfers data between synchronous devices at selectable data rate, from 1.2, 2.4, 4.8,
9.6, 56.0, 64.0, to 128.0 Kbps.
WINC 2400C provides all comparable features as WINC 900C, the existing 900 MHz version, operating
within the 2404 - 2483 MHz frequency band. The channel bandwidth of transmission is 4 Mhz and there
are twenty (20) independent 4 MHz channels available for choice when operation. Due to different
environmental application requirement, at least 3 different radiation power levels are offered, either
50mW, 100mW, or 500mW. Please check the product sheet that comes with the WINC 2400C you
purchased. Depending on the material of walls and ceilings, indoor operation as much as 30 to 50
meters. For outdoor unobstructed environment, the operating range of the modem is approximately 1
kilometer using the standard rubber omni-directional antenna. Using a high-gain Yagi antenna,
operating ranges can increase to up to 30 km.
The WINC 2400C uses direct-sequence spread spectrum technology with a fixed PN spreading code for
access. Differentially QPSK modulation is employed. The air-link operates in a Time Division Duplex
(TDD) mode which performs the full-duplex function to the user. Sensitivity is better than -85 dBm (not
including spreading gain). See Appendix C for a detailed technical specification of the modem.
In general, the WINC 2400C operates automatically with little need for user intervention. Both channel
selection and power control are automatic and transparent to the user guarantying that communications
occur at the lowest power sufficient to maintain the link on a channel that is least noisy.
