The general population knows little or nothing about mobile platform vendors who manufacture GSM, CDMA, 3G and LTE chipsets for mobile phones. When we talk mobiles the first buzz words we hear are IPhone, Nokia, Samsung or Android. Even the leading websites on technology do not discuss much about the evolution of this product family.

Our today’s guest is the very experienced telecoms engineer Kishor Kumar Gurusiddappa, he specialises in the telecom industry with a number of years of experience of working both for Network and UE vendors. Though he had always been interested in the Telecommunications and the dynamics of the industry, he himself calls his introduction to the telecom business an accident, the industry was in a state of recession when he graduated, so he started his professional career as a teacher in Embedded controllers and Operating Systems for Undergraduate level studies Siddaganga Institute of Technology in India, he got his first step in the telecom business when he joined Hughes Software Systems (Lucent technologies) in 2003 as a development and field support engineer, and there has been no turning back since. Now Kishor works as a senior consultant in the customer support organization in ST Ericsson, he calls him self a professional [...]

LTE Unacknowledged Mode (UM) RLC PDU overview is discussed in another tutorial. If you want to learn the basics of UM data PDUs you can check the following tutorial. LTE RLC PDU Structure & Encoding In this tutorial examples for most important encoding techniques used for UM RLC PDUs are discussed. UMD PDU with 5 bit SN (No LI) Assumptions Sequence Number (SN) Length: 5 bits Sequence Number: 1 Service Data Unit (SDU): 01 02 03 04 05 Framing Info: 00 00: First byte of the data field corresponds to first byte of a RLC SDU & last byte of the Data field corresponds to last byte of a RLC SDU. No Length Indicator is used. UMD PDU with 10 bit SN (No LI) Assumptions Sequence Number (SN) Length: 10 bits Sequence Number: 1 Service Data Unit (SDU): 01 02 03 04 05 Framing Info: 00 00: First byte of [...]

Handovers are an important part of every cellular communication system. They are used for providing mobility in cellular architectures. In UMTS systems different handover types have been introduced to cope also with other requirements as load control, coverage provisioning and offering quality of services. Handover aims to provide continuity of mobile services to a user traveling over cell boundaries in a cellular infrastructure. For a user having an ongoing communication and crossing the cell edge, it is more favorable to use the radio resources in the new cell – also called the target cell because the signal strength perceived in the “old” cell worsens as the user penetrates the target cell. The whole process of tearing down the existing connection in the current cell and establishing a new connection in the appropriate cell is called “handover”. The ability of a cellular network to perform efficient handovers is crucial to offer [...]
