1. General Description 1.1 Product Overview and Functional Description

EMW Co., Ltd. Introduces the high performance ISO/IEC 24771 KOINONIA Binary CDMA

compliant Ethernet bridge – EBM-B100. The compact size and low power consumption of this

system is targeted to IP Camera or Wireless digital video recording(DVR) and security applications.

EBM-B100 is a KOINONIA wireless personal area networks(WPAN) implementation providing

improved link robustness, extended range, increased throughput and better performance against

existing technology such as Wi-Fi and Bluetooth.

EBM-B100 adopts Daewoo’s highly-integrated Binary CDMA Baseband SoC---KWPAN1200A and

high performance Airoa AL2230S RFIC. The KWPAN1200A Baseband SoC is a high performance

single-chip medium-access controller(MAC) and baseband processor that is compliant with

KOINONIA wireless personal area networks(WPAN) spec ver.1.0/ver.1.1/ver2.0. The AL2230S is a

highly integrated RF transceiver IC for 2.4GHz band 802.11b/g applications, and combines all

functions of the transceiver in a single chip. AL2230S also integrates on-chip PA and PLL to help

you to minimize the use of external components to design an RF subsystem.

Compliance with ISO/IEC 24771 KOINONIA Binary CDMA standard, the EBM-B100 uses QPSK

baseband modulation technologies and supports Hardware-Based MAC Access Protocol

Management, Delayed Acknowledgement (DEL-ACK), Hardware-Generated Immediate

Acknowledgement (IMM-ACK), Channel Probing and Dynamic Link Quality Control. EBM-B100

security supports Hardware-Based Encryption/Decryption using CCM(CTR+CBC-MAC) Mode that

use the 128- bit AES as a Block Cipher Algorithm. (User selectable, default disable)

EMW FSC045-2 is circularly polarized antenna for Ethernet Bridge (EBM-B100) applications. High

Gain (3 dBic Typical) and broad Beamwidth (90° Typical) increases read range while low VSWR

(≤1.5:1) minimizes wasted power in Ethernet Bridge systems. The antenna’s light weight (30g) and

small size (45ⅹ45ⅹ2 mm) are ideal for Ethernet Bridge (EBM-B100) applications.
