From LTE-U to LTE-DSA: Solving The Capacity Crunch

LTE-UThe proposal by Qualcomm to enable LTE operation in unlicensed band (LTE-U) received a warm response from some (e.g. Ericsson, Verizon) and not so warm from others especially incumbents with strong legacy in Wi-Fi in both the vendor and operator communities. The contentious issue center on co-existence of LTE and Wi-Fi in the same band as Wi-Fi implements ‘listen before talk’ or in technical terms carrier sense multiple access (CSMA) as opposed to LTE where transmissions are scheduled by the base station. This issue plagued WiMAX in unlicensed bands and was topic of much work at the IEEE during standardization activities of that technology. Still, while the proposal is not yet an approved work item for 3GPP LTE Release 13, the next few weeks will most likely see this feature approved to include in the standard with completion timelines by end of 1Q 2016, when we very possibly can see actual systems deployed.

Data Sciences and Big Data in Telecom: A Big Deal?

Data SciencesThere is much hype in telecom. In just about every aspect of the network, new trends are shaping up: from the core to the radio access and through the transport network; in hardware, in software and in processes, buzz words and acronyms are aplenty. Worse, how often these acronyms are used out of context just to latch on a popular wave in a vain hope of marketing advantage? No wonder one can feel confused, even discouraged at times. What is real and what’s not? Who can really tell when there’s so much noise that masks real progress! Read more of this post
