Over 1,000 networks in more than 180 countries use Ericsson equipment, & more than 40 percent of the world's mobile traffic passes through Ericsson networks. The circuit analysis was made rather difficult from all the custom marked Ericsson parts and other ICs where it is not possible to locate a datasheet.Ericsson is a world-leading provider of telecommunications equipment & services to mobile & fixed network operators. The following 18 minute video shows the teardown step by step with explanations, high resolution pictures of content is in the last part of the video and also further down this post. That do not contain a board processor are monitored by other units. For control, most boards are equipped with a board processor (BP). However, if one of the processors fails, the program execution is moved to another main processor in the That is, there are no master-slave relationships between them. The processors that make up the MPC are equal in terms of control. RBS 3000 cooperate to form a main processor cluster (MPC) that executes most of theĬontrol software. The RBS application software is distributed over several processors using the interprocessor communication offered by the platform. It also supports all these technologies GSM / EDGE, WCDMA / HSPA and LTE. This RBS3202 indoor macro system is from around 2008. WCDMA stands for Wideband code-division multiple access. In 1999 Ericsson had 17 test systems running around the world with WCDMA, which is better known as 3G among normal people. AWG and European Wire Current RatingĪll the boards that I have comes from the middle row in the above picture and unfortunately I did not have any of the power amplifiers that are all at the bottom row.
