I like to focus on LTE capacity in the next few blog entries and present what can realistically be obtained. I have seen wild figures, mainly pushed by system vendors and consumed by many operators, journalist and writers who like to wow readers of the promise of new technologies. For network operators, erring on capacity expectations has negative consequences as capacity fundamentally impact the cost of the network both on the access side and the backhaul side. Inflated capacity figures would lead to under-dimensioning on the access side and over-dimensioning on the backhaul side. So, for example, if we think LTE cell will provide 100 Mbps of throughput while in reality can only do 50 Mbps, the operator will be short by 50% of capacity in the access network resulting in poor user experience (e.g. slow download, blocking, etc.) and will be 50% over the required capacity for backhaul in which case it’s investment in capacity that’s sitting idle. This is why it is important to get capacity expectations right. Continue reading
I started this blog in 2011 to share my insights into the technology impact on the wireless industry. Specifically, I am interested in the impact of technology on business, markets and society. I find myself often working with clients who want to assess a technology for its commercial benefits. But before answering this question, we need to answer many more basic questions. Thus my tag line for the site: making sense of [high] tech! Technology is often hyped and the fundamentals are obscured. It is challenging and bold to voice a contrarian view. But to make informed decisions, we need to ask the tough questions and face the facts. Numbers often help in clarifying a clouded picture.
I hope my posts will provide a balance between technology and its commercial and market impact. This is why I hope you will come back often to read my posts. I welcome the interaction through comments or even direct contact.
