1. Produ t Overview
1.1 Introdu tion
Using binary ode division multiple a ess (CDMA), the Wireless Ethernet Bridge
an send multi- hannel ode division multiple a ess CDMA signals through the
existing time division multiple a ess radio frequen y (TDMA RF). Based on this,
EMW developed a small, low-power system using a 2.4 GHz industrial s ien e
medi al (ISM) band.
Binary CDMA wireless ommuni ation enables stable, high-speed ommuni ation
with low interferen e, ex ellent se urity, and quality of servi e (QoS).
This produ t is designed for Internet Proto ol (IP) networks only in order to enable
the wireless transmission and re eption of IP amera video, audio, and data. It is
used for the wireless onne tion of se tions in a network that are diffi ult to onne t.
An integrated wireless bridge model with an embedded 2.4 GHz dire tional antenna
and a non-dire tional antenna model an also be supplied. Power is provided
through USB or an external DC sour e. For wireless ommuni ation, 10/100 Mbps
Ethernet is used.
1.2 Appli ations
1) Disaster monitoring
- Danger alarms for typhoons, heavy snow, heavy rain, river flooding, water
quality/soil ontamination, et .
2) Internal environment monitoring of residen es
- Intrusion monitoring
- Monitoring of hildren
- Home monitoring su h as rime prevention/fire monitoring
3) Management of fa ilities
- Automati management
- Remote ontrol
- Fire dete tion
- Crime prevention and danger alarms

4) Real-time multimedia transmission
- Real-time transmission of video/audio, user- reated ontents (UCCs), and data
5) Crime prevention monitoring
- Residential area monitoring and rime prevention systems
- Prevention of theft and damage, rime prevention/perimeter monitoring
6) Sensor networking
- Sensor node information olle tion
- Multi wireless transmission
- Data sharing
- Internal voi e alling
7) Constru tion site management
- Identifi ation of onstru tion progress and prevention of a idents
- A ess ontrol
- Installation of CCTVs in tower ranes
This is a solution to the amera re-installation and time problems that o ur as the
rane rises.
- Conne tion between management offi es and onstru tion sites
8) Temporary wireless network
This devi e an be used in sites su h as onstru tion sites and temporary buildings
that require stable ommuni ation and an Internet network at low ost.
9) Thanks to the ompa t size and low power onsumption, it an be applied to
smart grid appli ations, high-speed WPAN networking appli ations, wireless home
network appli ations, wireless digital video re ording, and se urity appli ations
10) Provides a wireless dam water level management system where a wireless LAN
is diffi ult to install
11) Forest fire monitoring where wiring is impossible
12) Wireless se urity system for national borders and base amps
13) CCTV for prote tion of power generation fa ilities
14) CCTV for wireless traffi monitoring systems/emergen y disaster monitoring on
the road
- Transmission of a ident and disaster situations in unspe ified lo ations on the
road

3.1 Devi e Installation
3.1.1 Conditions for Monopole Antenna Installation
Figure 1-1. Monopole Type
- As the monopole antenna is non-dire tional, onsider the distan e between the two
produ ts before others.
- The distan e “N” may vary by the antenna hara teristi s and the RF output power.
See Chapter 6, “Dimensions and Spe ifi ations.”
* Note: The distan e “N” is based on the measurement in an open site with no
obsta les.

- As the pat h-type antenna is dire tional, it has a beam width property. Therefore,
overage must be onsidered in addition to the distan e between two produ ts.

* Note: These data are based on a beam width of 90°.
- The distan e “N” and overage “K” may vary by the antenna hara teristi s and the
RF output power. See Chapter 6, “Dimensions and Spe ifi ations.”
* Note: The distan e “N” and angle “K” are based on the measurement in an open
site with no obsta les.
