Does their caching work for secure connections?
A lot of bandwidth-hogging content such as YouTube is delivered over HTTPS now. Can they cache that?
In the race to keep mobile performance in line with user demands, carriers around the world are spending big on splitting their cellular networks into ever-smaller chunks. New research suggests that adding some spinning rust to base stations could help improve efficiency, at lower cost. The modelling, carried out by Ejder …
LTE network vendors are working on this right now, and in some cases have lab and real world demo results that show a significant improvement to end user performance. The content can be sent from local cache scheduled directly onto the air interface, rather than have to dribble it through the entire backhaul (and internet pipe) network.
Vendor propaganda to make mobile operators spend more (e.g. Three who don't understand).
Unless your infrastructure is rubbish, then the bottle neck is ONLY at the air interface. The backhaul has to be able to manage full peak base station traffic anyway. If your Base Station is only using copper or ancient Microwave too slow (modern microwave and fibre can feed easily 5 to 10 base stations) then this is like lipstick on a pig.
You need fibre or dedicated microwave link anyway for any decent basestation.
Caching needs large number of users to be effective.
A Mobile Basestation can only serve video to about 15 users if signal is good, less if signal is poor.
This is about as useful as a cache in a WiFi Air point (which isn't useful). Which actually on average can server more users faster than LTE!
Caching may be useful at the edge Router, Exchange or Cable head ends, waste of money at a Mobile or even fixed wireless (x 10 to x30 capacity) base station.
We'll be generous and assume it's done properly.
Just because Americans and other lower orders have started to interpret Boffin as a derogatory term, doesn't mean that this is the case at El Reg, where the word Boffin is used in it's most original sense as a term of endearment and respect for those engaged in breakthrough science and engineering, frequently associated with sheds and pipe-smoking.
Since both of you failed to use apostrophes properly, I see no reason to consider either of your opinions, which is just as well, as I am an American who values both boffins and the term boffin, thus handily proving all of your prejudices expressed within this forum wrong in any case.
