T-Mobile 3G wireless Data Coverage in Youngstown Ohio
Avenue it is patchy. Sometimes it is full 3G and sometimes it falls back to G/Edge coverage. The speed ranges from 300kbps -1.3Mbs. What is interesting is that coverage could change within few feet as it occurs behind my apartment complex where within few feet the coverage can change from G/Edge to 3G.
Most of these test were done using Mobile Speed Test.com
Some of the images showing the data transfer rate using Google Nexus one phone on T-mobile network are shown below
I found a wireless speed test app on the Android market. The test is same as the test available the web site http://speedtest.net/
I collected the data at three locations and the results are shown in the table below:
The last two column show the download and upload speed for the T-mobile wireless network
Also some of the results in picture form are shown below
The data speeds vary widely based upon the locations.
The first location of the data collection is shown in the map below

The second location of the data collection is shown in the map below:

The third location of the data collection is shown in the map below:

Although T-mobile wireless data coverage map shows a 3G data speed but these map show that that is not the case. Even where the phone indicator shows a 3G speed the data rates are considerably slower. It however dramatically increses in the southern part of the town most notably in the Boardman area.
The promised data rates for wireless 3G data network according to Wikipedia article are
Data rates
ITU has not provided a clear definition of the data rate users can expect from 3G equipment or providers. Thus users sold 3G service may not be able to point to a standard and say that the rates it specifies are not being met. While stating in commentary that "it is expected that IMT-2000 will provide higher transmission rates: a minimum data rate of 2 Mbit/s for stationary or walking users, and 384 kbit/s in a moving vehicle, the ITU does not actually clearly specify minimum or average rates or what modes of the interfaces qualify as 3G, so various rates are sold as 3G intended to meet customers expectations of broadband data.
What becomes obvious is that it is difficult to get full strength network connection using wireless data connections. Some fault can be placed on the wireless network providers but mostly it is the limits of the technology at this time.
However, for some one like me it is a big improvement over the old GPRS wireless connection that I had for the last eight years. It delivered data at 14.4kbps. Hopefully with the introduction of 4G the field will become more competitive and we may get better wirelss data internet connectivity.

Growth of Worldwide Internet Users


SourceIt shows that there is substantial growth in the adoption of Internet across the Globe. The rate of adoption at best can be described as phenomenal. No communication and Collaboration technology has ever seen such a fast rate of adoption in the past.
However, the charts showing percent of population only tell part of the story. If one looks at the absolute number of users another picture emerges:
| WORLD INTERNET USAGE AND POPULATION STATISTICS | ||||||
|---|---|---|---|---|---|---|

We notice that even though Asia is behind in the percentage adoption rate but as absolute numbers 738+million online user versus 418+million online user in Europe, leads the pack in the total number of users. A further breakdown of online users in top countries of the world is shown in the table below:

What we find that China leads the pack in the number of online users while US is behind it. China's neighbor India with similar population shows up at number fourth with substantially less number of users online when compared with China.
We all know that communication and collaboration technology is the life blood of culture and that in turn determines the type of society one will have. Therefore, these numbers become indicative of human development across the globe.

Netbooks with Robert Scoble
Netbooks overcome the limitations of the current ebook readers who are mostly limited to displaying text and pictures. They are capable of playing music and videos. A user can surf the net through wireless connectivity.
Here is a video that discusses about the latest crop of Netbooks
Netbooks will be a replacement for the current textbooks once we have the appropriate Internet infrastructure is in place. Also, we have good quality learning material available on the Internet. They should serve as an ideal elearning delivery appliance.
