Unified Communications
According to ABI Research the market for unified communications is set to rise from $302 million in 2008 to $4.2 billion by 2014.
“We foresee a booming market for managed services, simply because unified communications are tricky and many companies won’t want to spend the time and effort to do it themselves. That applies to the market as a whole, but particularly to smaller businesses.”...

N96 vs. N95
Just noted that the N96 resembles too much the N95. There is little doubt that the N96 is by far the most advanced device in terms of networking: wireless PAN/LAN/WAN and now DVB. Slider and GPS/Maps/navigation too. But all these (besides DVB) were available on the N95 as well. Even the battery capacity (merely 950 mAh) is the same but it is supposed to deliver longer battery life (why?). Alas,...

Was Nokia R&D about to move out of Finland?
According to the Helsingin Sanomat International Edition (HS) the “former Chief Technical Officer and Head of the Nokia Research Center Bob Iannucci […] apparently planned to move the research & development facility away from Finland.” Iannucci joined Nokia in 2004. HS notes that about 450 people work at NRC Finland today—presumably that includes both NRC Helsinki and...

SMS: The killer app
The IEEE Spectrum run an article titled “thx 4 the revnu.” According the article, the world’s 3.3 billion users spent approximately USD 100 billion to 1.7 trillion text messages in 2007. Global music sales were approximately USD 19.3 billion. On New Year’s 2007-2008, 43 billion messages were sent according to ITU and Acision, a Dutch SMS service provider.

Android-powered T-Mobile G1, dissected
The Nikkei Electronics Teardown Squad started publishing their findings of the HTC-manufactured T-Mobile G1 tear down. G1 runs the Google Android software stack. Interesting findings:
The antenna is a spirally-cut, black-painted, 0.2mm-thick aluminum foil attached to the chassis.
Made in Japan: The main board is made by Panasonic; the digital compass is based on a magnetometric sensor by Asahi...
Nokia loses smartphone share, needs new...
Petri Koskinen of Talouselämä writes (in Finnish) that Nokia needs a quick flow of smartphones: Although the market for smartphones has grown by 40% in Q3 2008, Nokia’s share has dropped from more than 50% to 35% in this segment. The winners? Apple and RIM. The recently released N96 resembles too much the N95, released two years ago. Koskinen wonders how can it be that a giant like...

Maemo release 5 to include cellular connectivity...
Ari Jaaksi reveals that the Maemo “5th release will include cellular connectivity for the High Speed Packet Access (HSPA) data.” This means that the future Maemo MIDs will have integrated support for four wireless access network types (wireless PAN, LAN, MAN and cellular) using Bluetooth, Wi-Fi, WiMAX and HSPA. I wonder if they will also have support for IEEE 802.21 and some advanced...

Finns have taken to wireless Internet connection in a big way this year. According to a report by the Finnish Communications Regulatory Authority (FICORA), there were more than 300,000 broadband connections in Finland operating on a USB modem in June this year. This is twice as many as there were at the end of 2007. During six months, the total number of all different types of broadband...

The challenges facing tech companies are now spreading outside the US and all along the technology chain. Demand in Europe and Asian emerging markets that had partly offset US weakness is slowing. Corporate and domestic customers are both being squeezed. Forrester’s survey found nearly half of financial services companies, their balance sheets creaking, have trimmed IT spending. Ciena...

Cisco sees Finland’s low standing as a cause for concern; at the beginning of the decade, Finland was “right at the top” in broadband services. In Sweden, state and local authorities have taken on a much stronger role in setting up Internet connections than those in Finland have. Hundreds of millions of euros in public funds were invested in 2001-2007 to extend the high-speed fibre optic cable...

WiMAX on the ``Holy Mountain''
Hellenic Telecom announced today the deployment of a pilot fixed WiMAX on Mount Athos, aka “Holy Mountain”. According to this press release (in Greek) the pilot network includes six IEEE 802.16-2004 operating at 3.5 GHz, and is powered by solar and wind energy. The press release also seems to imply that the pilot fixed WiMAX network serves as backhaul for standard ADSL connections...

Mobile WiMAX Overview
One of the technologies that can lay the foundation for the next generation (4G) of mobile broadband networks is popularly known as “WiMAX.” WiMAX stands for Worldwide Interoperability for Microwave Access and is designed to deliver wireless broadband bitrates, with Quality of Service (QoS) guarantees for different traffic classes, robust security, and mobility. This article provides...

A salient feature of upcoming communication networks is unprecedented dynamicity, which can only be handled in a large scale by introducing self-configuration and self-maintenance mechanisms. The main contribution of this paper is the definition of a protocol toolbox for efficiently supporting communication for self-configuration and self-maintenance in dynamic environments. We leverage our...

Despite the significant interest in WiMAX technology and deployment, there are very few publicly reported measurements from testbeds and field trials. As such, most WiMAX studies employ simulation and modeling. This paper contributes to our understanding of what is realistically possible using off-the-shelf fixed WiMAX equipment today. We employ multiple competing traffic sources over a...

Forthcoming wireless communications will be charac¬terized by the ubiquity of multiaccess. Despite the inherently increased complexity, end-users should be able to take advantage of the most suitable access network. Thus, access selection in an environment with different overlapping radio technologies is of central interest and an architecture is needed that performs equally well on single- and...
