The results of the spectrum auction in Spain were published on Monday. The auction was for digital dividend band frequencies in 800 MHz, a slice of 900 MHz spectrum and 2.5 GHz spectrum. Continue reading
I have listened to a few webinars recently by some of the major microwave backhaul vendors, all with the message that microwave has enough capacity to support required LTE data rates. It is evident that network operators have been pushing these vendors for higher data rates. Microwave after all cannot compete with fiber on capacity and MNOs (Mobile Network Operator) have been laying lots of fiber in anticipation of LTE network roll out. Continue reading
I have already address peak LTE data rates and showed how they’re calculated. But what type of data rates would a user actually experience? This is what really matters from a quality of experience perspective.
A number of factors impact the ultimate capacity offered by a cell site. Two critical factors are interference and network loading. These factors are inter-related: higher network loading, which is a measure of the number of active subscribers, results in greater interference. Continue reading
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
Let me introduce myself. My name is Frank and I have been working in the wireless infrastructure industry for over 18 years. I love this industry and have seen it grow through different phases – never a dull moment. One wave of technology after another; so many of ideas and solutions; successes and failures… It’s all so fascinating and that’s what I want to blog on. I have worked for different companies including wireless carriers in North America and in other international markets, equipment vendors and consulting companies. I cannot claim that I have seen it all, so it’s my hope that my blog site will eventually grow to get contributions from others in the industry…
This is why I hope you will come back often to read my blogs: I want to provide a good view of new technologies and insightful comments. I like to look at both the technical aspects and the commercial ones. Ever wondered what will fly and what will fail? There are so many reasons. I intend to address these in my blogs…
So, what will I blog about? I am interested in a large number of issues related to the wireless industry: new technologies, business models, financial developments, and so many other topics. I have recently been heavily involved in small cells and heterogeneous networks, wireless backhaul, and 4G networks. I will write about these and so many other topics.
I am looking for comments because only through interaction, we can evolve our thinking and knowledge. I encourage you to post comments. If you don’t agree, say so!
I look forward to growing this bog site to include valuable insights so you can come back again!
