iRon

For my son's birthday, we got him a iPod; my daughter got an iPhone for hers. I was extremely delighted to receive an iPad for my birthday. Thinking along the same lines, for my wife's birthday, I got her an iRon. Thats when the fight started...

Shunning mobiles in favour of Landlines

I guess its time to clean the cobwebs off the landlines. I was reading David Chambers analysis on Homezone tarrifs and it reminded me of the time when I would get big bundle of voice minutes to call using my mobile from home. In those days the voice quality seemed better, signal strength indicator was high and there were hardly any dropped calls.

Nowadays, the signal strength seems to have gone worse whether I am in the office or at home, the voice on the calls keeps breaking, there are too many dropped calls.

To give you an idea of what's going wrong; My phone kept stationary at the table has 4 bars strength of 3G/HSPA, it suddenly becomes 1 bar after 2-3 minutes then hands me over to what the phone says GPRS then the phone says EDGE. If the phone says EDGE then my calls drop within 2 minutes. If my phone says GPRS then I am worried that if it hands over to 3G then my call will drop. If the phone says 3G then unless there are 3 bars, the voice breaks.

Last week I used my landline phone after maybe a year or so and that reminded me how good the voice quality is. In theory the voice quality using mobile phone should be as good as the landline but in practice that may not be true. Of course the wideband AMR can offer much better HD voice but I need reliable voice more than HD voice.

So for the time being, I am going to be sticking with the landlines as far as possible due to reliable and clear communications and wait for the mobiles/networks to catch up.

Mobile TV in China not as successful as initially thought

A wise consultant once told me that when the analysts were asking people if they would be interested in Mobile TV, nearly everyone said yes. What they didnt ask is what those people understood by Mobile TV. From a lot of users perspective, Mobile TV meant Youtube which is not what mobile community understands it to be.

Not long back we talked about Mobile and IP TV becoming popular in China. According to recent news in InformationWeek, it falling much short of expectations:

Commercial development of China's mobile TV service is falling far short of expectations. Of the 1.5 million users of China multimedia mobile broadcasting (CMMB), less than 3% are actually paying for the service, creating something of an embarrassment for China Mobile, the main backer of the standard.
CMMB was developed by the State Administration of Radio, Film, and Television (SARFT) based on Satellite and Terrestrial Interactive Multiservice Infrastructure (STiMi) developed by TiMiTech, a company belonging to the Chinese Academy of Broadcasting Science. The standard was announced in October 2006 and is similar to Europe's Digital Video Broadcast-Handheld (DVB-H) broadcasting standard. Since then CMMB has been rigorously promoted by China Mobile and is bundled with its 3G network.
Sources say that by the end of the second quarter, 2010 domestic sales of CMMB handsets were around 1.5 million, approximately 30% of total 3G mobile phone sales at China Mobile, and much lower than the 50% target set by the operators. The service has been operational for more than a year but formal fees have only recently been introduced, which range from $1 to $3 per month. The small take-up of the service since fees were introduced does not bode well for the future of mobile television in China.
China Mobile was hoping to attract more paying customers with its World Cup offering, but this may have been wishful thinking. Analysts believe that the company's broadcasting and mobile communications divisions are lacking in unified policy and have no clear development path.
With widespread proliferation of cheaper "shanzhai" -- or copycat -- handsets, it is difficult to reach all potential customers. The CMMB technology is expensive and can only be found in specific dedicated smartphones.

Furthermore, there are more attractive and diverse streaming packages available from third parties. A clear advantage needs to be provided in order to entice users to use CMMB. China Mobile insiders say that they need to be following the advertising model used by mobile broadcasters in other countries because people are unlikely to pay for content, especially if they can find that content for free from a regular TV or desktop computer.

Mobile Phones 'Ad-Hoc Networks'

Picture Source: Daily Telegraph

Couple of years back I blogged about MCN and ODMA concept. Another variation of this idea is now in news again.

From the Daily Telegraph:

Australian scientists have created a mobile phone that can make and receive calls in parts of the world that would normally have no reception.

The phones contain a built-in mini-tower that allows them to connect to other phones via Wi-Fi and create their own network.

Researchers at South Australia's Flinders University devised the phones to work in the event of a natural disaster or terrorist attack when normal mobile phone services had been cut off.
Dr Paul Gardiner-Stephen said the phones had been tested successfully in the remote Outback where mobiles cannot pick up a signal.

"There was absolutely no infrastructure or support for the telephones so they were acting entirely on their own to carry the calls," he said.

The phones are unlikely to replace existing mobile systems, but could be combined to create fail-safe communication.

"One of our dreams is that every phone will come out with this one day so that if there is a disaster anywhere in the world everyone's phones will then switch over to this mode as a fallback," Dr Gardiner-Stephen said.

"When the infrastructure is knocked out we still provide good service while the traditional mobile phone network provides no service."

At the moment, the signal between phones is limited to a few hundred yards, but the team hopes to expand the range in the future.

I dont see them becoming reality for quite some time to come but its an interesting concept.

This is not the first time this idea is being proposed. As I have discussed, ODMA was intended to do something similar but did not take off. MANET's are other areas that have been worked on for quite some time and you can find good ideas and journal papers. There is also this paper talking about Ad-Hoc networks for mobiles using Bluetooth.

In fact going many years back, Iridium idea was launched with something similar in mind. I remember reading jornal papers back in 1996 that mentioned that Iridium phones will work like landline phones when you are in your house and will work as cellular when out of house and in an area with cellular coverage. If there is no cellular coverage then it will rely on Satellite communication. Of-course in those days nobody thought data usage will become this popular and so it was focussed on voice. Still I cannot see this happening for many years to come.

6 Billion Mobile Connections by June 2011

Just saw on Tomi's Blog that the number of active connections worldwide reached 5 Billion.


According to Wireless Intelligence:



The number of global mobile connections surpassed the 5 billion mark this week, according to new Wireless Intelligence data. The milestone comes just 18 months after the 4 billion mark was reached at the end of 2008 and is in line with our earlier forecasts. We predict that the 6 billion global connections milestone will be achieved in the first half of 2012. According to our data, the mobile penetration rate on a global basis at the 5 billion mark was 74 percent, compared to 60 percent at 4 billion. The highest penetrated region is Western Europe on 130 percent, while the lowest is Africa on 52 percent. Eastern Europe (123 percent) is the only other global region to have passed 100 percent mobile penetration.


The main driver of growth continues to be the Asia-Pacific region, which accounted for 47 percent of global mobile connections at the end of Q2 2010 (see table). This is up around 5 percent from Q4 2008 when the 4 billion connections mark was reached. Growth in Asia-Pacific is due mainly to ongoing growth in China and India – the world’s two largest mobile markets – which offset slowing growth elsewhere in the region in markets such as Pakistan and the Philippines. Growth was slower in mature markets such as Europe and North America, which now account for around 27 percent of global connections, compared to over 30 percent 18 months ago.
