Next to the London tube, New York's underground transportation system is one of the few places I have noticed over the years that still lack wireless coverage on a broad scale. It looks like things are changing though as I was positively surprised to have coverage in one of New York's metro stations recently. Have … Continue reading New York Metro Wireless Coverage – First Stations Connected At Last
Heise news reports today about an LTE field trial T-Mobile is performing right now in Innsbruck, Austria and lists some interesting details about it: Base stations: The outdoor test network consists of 20 base stations with three sectors each, supplied by Huawei. Note: That's a good network setup to test the impact of neighbor cell … Continue reading LTE Test Network with 20 Base Stations in Austria
I've recently been shown an interesting comparison that seems to suggest that wireless is really loosing out because despite wireless speeds rising, fixed line speeds keep rising much quicker. An interesting twist of numbers to get to a single message but in practice, things are a bit more difficult and the conclusion to which that … Continue reading Is the Speed Gap between Fixed an Wireless Widening?
Lots of things happened in 2008. I usually have the impression that the industry is moving too slowly for me. However, as the following overview shows, this impression is not really accurate, one just forgets all the things that happened over the year too quickly.
Intel has decided to make a comeback to mobile computing and has started a fight with its new Atom platform against ARM, who's processors drive the majority of medium- and high end mobile devices today. Not much has been heard or seen from them since then, except for a few bulky prototypes and some eeePCs driven by first versions of this chipset. However, I expect more to come in 2009. In January I also mused on the fact that LTE and SAE have no built in voice capabilities and that finding a solution that works will be on of the main factors deciding over how long it will take for LTE to become a success and 2G and 3G becoming a thing of the past. I've picked up the topic several times since then as at least 4 solutions have been proposed since then, all with their pros and cons. Unfortunately, that is 3 too many.
While doing some research on how capacity will grow in fixed line and wireless networks in the future I stumbled over the following thing right in my neighborhood: Future bandwidth increases on the last mile to the subscriber come with an additional cost in comparison with today’s standard ADSL or ADSL2+ deployments because of extra … Continue reading DSL Gets ‘Base Stations’
HSDPA, EVDO, WIMAX, LTE, you name them, they all go advertising these days with "mobile can now do broadband, too". I think this is true to a certain extent, if one keeps in mind that overall capacity that can be delivered by a mobile system in a densely populated area can not match capacity of … Continue reading Broadband Was Yesteray – Wideband’s The Future
I recently visited a friend of mine in Paris who is now working for a N2NSoft, a company with quite an interesting product: Before deploying networks or even before applying for a license, operators need to know how much to spend on the wireless and fixed infrastructure to see if their business model is sound. … Continue reading Simulating 50.000 Mobiles
