1. Introduction

EST-101B Portable mobile phone signal detector can exactly detects the CDMA, GSM, DCS and PHS (3G) mobile phone signal in 1-10 meters. It'll vibra or flash warning when finds the mobile phone signal and show the type of the signal. This detector only work on mobile phone signal and no interrupt on other signals.

2. Technology

Detect widebands:

a. can detects the RX frequency(CDMA) 824MHz~849MHz

b. can detects the RX frequency(GSM) 890MHz~915MHz

c. can detects the RX frequency(DCS) 1710MHz~1785MHz

d. can detects the RX frequency( PHS/3G ) 1920MHz~1980MHz(2100-2200)

*signal detecting range:Radius 1 ～ 10M. (depends on the strength of the mobile signal in local area).

*Working light(Blue)& RF detecting light(Red).

*When it find the mobile phone signal, the red indicator will be on, the closer to the mobile phone, the more lights will be on, and show the signal’s type.

*Alarm:flash or vibra(choice).

*Earphone:for secrecy reason, when someone using the phone, you can hear the beeping by earphone.

*Antenna: Inner omni antenna
