With so many different possibilities and options available to the operators for deployments it is necessary that the planning is done in such a way as to keep the interference to minimum and throughput to maximum. Let’s look at two simple deployment situations.   For simplicity let’s assume that the operator has won 20MHz of contiguous spectrum. We have 5 UE’s. UE#1, UE2 and UE#5 are basic Rel-8 LTE UE’s and UE#3 and UE#4 are LTE-A UE’s with support for Carrier Aggregation (CA) and enhanced Inter-Cell Interference Coordination (eICIC)     Operator 1 decides to split the 20MHz spectrum into 15MHz for macrocell and 5MHz for small cell. In this case:   UE#1 and UE#2 get 5MHz of spectrum   UE#3 gets 15MHz + 5MHz using CA. Total 20MHz   UE#4 and UE#5 get 15MHz of spectrum.   The advantage of this scenario is a simple Hierarchical Cell Structure (HCS) deployment. ... (more)

Huawei for World Dominance?

Apart from all the Google news lately that has major relevance (like the new programming language 'Go'), there were two news of major significance that I think went through a bit quiet. #1 Huawei signs a €170M deal with Telenor for LTE rollout #2 Huawei will demonstrate TD-LTE with China Mobile for World Expo in Shanghai   7 years ago, I gave a presentation in Sweden in a forum addressing Asia that was managed KTH (Royal Institute of Technology) and the essence of my presentation was the 5-year planning for Chinese Enterprises - and I used the telecom sector to exemplify my thi...

Cisco RAN Backhaul on the M.O.VE #2: Beijing, China

By Craig Conaway   As I reflect back on our week in China I am impressed by several things:  The Modernization, the Order and the sheer masses of everything, people, cars, new building projects.   On one hand if you dropped me off downtown Beijing at Simultan Village, an upscale outdoor mall with Giant Video screens, beautiful designer water fountains and the latest in retail including an Apple Store, I could easily confuse the fact thatI was in Plano Texas at the Legacy Center. Similarly the under ground subway reminds me a great deal of similar transits in NY, DC and Munich... (more)

May I Borrow A Cup of Wi-Fi?

At one time the knock on the door was a friend or neighbor looking to borrow a cup of sugar or the hedge trimmer.  They may still be looking for those things, but increasingly they are also looking to connect up to our home networks when they come to visit.  People are now carrying with them an average of 2.6 mobile devices according to recent mobile research by Cisco Internet Business Solutions Group.  And people want to make sure that these devices are connected to the Internet.  Often the first question following the pleasantries when friends and families enter our homes is c...

Zen and the Art of Network Architecture

"...I'll have one with everything."  That is the possibly recognizable punch-line to an old joke about the Zen master ordering a hot dog.  I am borrowing this as a theme for the on-going transformation of network architecture. Any successful design must follow the functionality required by the end-user. People want to be able to access information, entertainment, work, and all their friends whenever and wherever they happen to be at the time.  While we love to talk about Triple-Play, Quad-Play, and Any-Play, we still see (for the most part) operators building on from a foundation...
