From 5eb17e28acdd6fba22a1f2e60f4d55aaef18b47a Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Sat, 9 Jan 2016 13:13:37 +0100 Subject: VIRT-PHY: Initial check-in of a new virtual BTS This patch adds a virtual physical layer designed to simulate the Um air interface between BTS and MS. It does so by encapsulating MAC blocks (Layer 2 PDUs) via GSMTAP and sending them through multicast UDP streams, both in uplink and in downlink. The purpose of this is enable testing without any radio hardware or related licenses. OsmocomBB has recently received as similar patch-set, adding a virty_phy executable that can be run on a PC instead of the classic 'layer1' firmware on a real phone. Using GSMTAP means that one can use unmodified wireshark to decode the messages exchanged on the virtual Um layer. This code was originally started by Harald in January 2016, continued by Sebastian Stumpf in late 2016 and early 2017, and finally completed by Harald in July 2017.
