No Antenna Port on your GSM cell
phone!?
Whoops! How can you hook up an antenna cable to a GSM phone like a Blackberry that has no antenna port? Well, if you use a Blackberry but the signal inside your home (or office) is not strong enough to make calls -- there is something you can do. Buy another NO Plan GSM phone (Global System for Mobile communications) that has an antenna port, and while at home swap your Blackberry SIM chip (Subscriber Identity Module) to that "home phone," and connect up our dual band, tri-mode Trucker Antenna to it and make calls.
GSM Network
GSM (Global System for Mobile communications)
GSM, a 2G technology, is the de facto European standard for digital cellular telephone service, and it is also available in the Americas. GSM is the most widely used of the three digital wireless telephone technologies (TDMA, GSM and CDMA), and it supports voice, data, text messaging and cross-border roaming.
SIM Chip
The SIM (Subscriber Identification Module),
a removable plastic card that contains a users data, is an essential element in a GSM network.
GSM operates in multiple frequency bands, GSM 900, GSM 1800, GSM 1900. When GSM is working on a radio frequency of 1800 MHz, it is sometimes referred to as DCS 1800, GSM1800 or PCN.
An Amplifier / Repeater for digital 1900 MHZ GSM Service
You can set up a digital 1900 MHz Amp/Repeater system at home or in your office and the GSM Blackberry cell phone will work with no direct connection to an antenna cable.
