OpenBTS (Open Base Transceiver Station) adalah sebuah BTS GSM berbasis software, yang memungkinkan handphone GSM untuk menelepon tanpa menggunakan jaringan operator selular. OpenBTS dikenal sebagai implementasi open source pertama dari protokol standard industri GSM.

Perkiraan harga sekitar Rp. 15-25 juta / buah, jauh di bawah BTS Selular biasa yang biasanya dalam orde ratusan juta hingga beberapa Milyard rupiah.

Ketakutan utama biasanya bukan di teknologi tapi justru di regulasi (menyedihkan memang).
