I can't quite remember when I last depended on 2.5G EDGE to connect my notebook to the Internet, must have been a couple of years ago, perhaps back in 2008, as 3G has become pretty ubiquitous at the places I went. But recently in Thailand, where 3G has not yet quite arrived and the hotel … Continue reading On the EDGE again

Already since the very early days of 3G, there have been 5 air interface states in the specs: Cell-DCH, Cell-FACH, Cell-PCH, URA-PCH and Idle. In all networks I have so far encountered, only Cell-DCH, Cell-FACH and Idle have been used. I haven't seen the other two states yet, which can reduce the time it takes … Continue reading 3G Cell-PCH in the Wild

When HSDPA was first specified it was unfortunately forgotten to put an indicator somewhere on the broadcast channel so a mobile could distinguish a 3G network from a 3.5G HSDPA network and show something to the user. It was added in a later release of the standard but I haven't seen a device yet that … Continue reading HSDPA Indicator

Looks like I finally found a Google Application to which there is nothing comparable form my use on both notebook and mobile phone: Google Reader for blog reading. In the past I’ve been using Thunderbird for the purpose but it hasn’t been very practical over time for me since I don’t have a lot of … Continue reading Google Reader – On the Go

I wonder what will happen next year, when tariffs for data roaming will be capped at 1 euro per megabyte which at current national pricing levels of many prepaid and postpaid contracts means that it might become cheaper to access the Internet from the mobile phone while traveling abroad than while at home!? Despite many … Continue reading Mobile Internet Access Cheaper Abroad Than At Home?

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.

January

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.

Each year, mobile Internet access from PCs and other non mobile phone devices gets better and better and as I write these lines, I am sitting in a railway station in Paris, connected to the Internet via a 3G USB dongle at multi-megabit speeds. I travel a lot and depending on the country I am … Continue reading Forecasts for Mobile Broadband Use From PCs and MIDs

Unified Communications – The holy grail of combining information technology and telecommunication. There are lots of different opinions on what exactly UC is and when I was offered to have a look at a book giving an introduction, I couldn't resist. Unified Communication Solutions – A Practical Business and Technology Approach by David Kim, Michael … Continue reading Book Review: Unified Communication Solutions
