UE Antenna Sizes on different frequencies

The biggest problem with Antennas for mobiles and now the tablets have been how to arrange antennas for MIMO since the wavelength needs to be λ/4. The picture gives an idea how the antenna size changes with different frequencies. Higher frequencies are better for having multiple antennas as their length and the distance between then decreases.

Mobile Developer Economics 2010 and Beyond

A new report "Mobile Developer Economics 2010 and Beyond", offers many new insights into mobile developer mindshare, and analysis into every touch point of the developer journey, from platform selection to monetisation. The research is based on a set of benchmarks and a survey across 400+ developers globally, segmented into 8 major platforms: iOS (iPhone), Android, Symbian, BlackBerry, Java ME, Windows Phone, Flash Lite, and mobile web.

In terms of developer mindshare, our research shows that Symbian and Java ME, which dominated the developer mindshare pool until 2008, have been superceded by the Android and iPhone platforms. Despite Symbian remaining in the pole position in terms of smartphone market penetration, ‘out-shipping’ iPhone 4 to 1 and Android many-times to 1, the signs of dissatisfaction with the way the Symbian platform has evolved have long been evident.

Indeed Android stands out as the top platform according to developer experience, with close to 60 percent of developers having recently developed on Android, assuming an equal number of developers with experience on each of eight major platforms. iOS (iPhone) follows closely as the next most popular platform, outranking both Symbian and Java ME, which until 2008 were in pole position.

Interesting Pic: Blackberry Evolution

The first blackberry was released around 1999 and the Blackberry bold (the last one in the pic above) was 2009. You can see that how the phones have changed radically in the last 10 years.

Video Calling: Boon or Bane?

When 3G was launched, the operators were clueless as to what 3G can do. The only way according to them to sell 3G was to to market 'Video calling'.

I am not sure how many of you have used Video calling, but I love it. Shame that the operators have priced it so ridiculously that I only used it when I had them inclusive in my package. Otherwise paying £0.50 per min seems exorbitant to me.

We have so many other options like Google Chat with Video and Skype Video chat available which is very convenient (and far much cheaper) according to me. Skype client is available on mobiles but still Video is not included. Its just matter of time before Video calling is included part of the VoIP client. All handset manufacturers are scared to include the feature so as to avoid the ire of operators. Maybe we will have to leave it to iPhone again to break this barrier as well.

The following is from Reuters news article:

Research in Motion Ltd says it is far from certain that video will become the "killer app" that defines smartphones, but even so the BlackBerry maker says developing more efficient delivery is necessary to prevent video from choking airwaves.

The popularity of feature-rich smartphones such as the BlackBerry, Apple's iPhone, and Motorola's Droid has surged, but they use as much as 30 times as much bandwidth as regular mobile phones to run the applications, or "apps," that make them so popular.

The surge in traffic triggered by video and other apps has led to more dropped calls and choppy service. As video on smartphones becomes more popular, it is leading to more congestion, and forcing carriers to spend billions to upgrade networks and buy more wireless spectrum.

"I still don't know and I don't think anyone knows if video is a killer app for smartphones," RIM Co-CEO Mike Lazaridis said at a conference hosted by a unit of Toronto Dominion Bank on Friday. "I don't particularly think it is."

Lazaridis said that even if video did not become the defining app for smartphones, it is already presenting a big challenge to networks.

Analysts have praised Waterloo, Ontario-based RIM for its relatively bandwidth-light BlackBerrys, which route most emails through the company's own servers. This is a legacy of the company's earlier days when it was seeking a faster, more secure mobile email service.

RIM also sends web browsing, Facebook, Twitter, and data from a wide number of BlackBerry apps through its own servers.

That makes browsing and using apps on a BlackBerry three to eight times as efficient bandwidth-wise as on the devices of RIM's rivals, said Lazaridis.

"What that means for the carrier, though, is after they have committed all those billions of dollars on new network technology and new network spectrum, they can have three BlackBerrys using the same network capacity as one of the other smartphones."

Lazaridis said RIM would invest more in technology that provides efficiencies to carriers, including when it comes to video.

He pointed to RIM's 2006 acquisition of SlipStream, which specializes in data acceleration, compression and network optimization technology.

"They had some amazing technologies for compressing everything from web content, documents, and video. So, you never know, the research that we do is very important, it's always borne fruit and we are hoping that we can continue to ... provide tangible efficiencies to the carriers."

mHealth and keeping fit Apps for Blackberry

From Brian Dolan, Mobile Health news:

When Fraser Edward joined Research In Motion (the company behind BlackBerry) four years ago, the device maker had only three partners for mobile healthcare applications, Edward said during a panel session at the American Telemedicine Association in Las Vegas. Today, Edward is RIM’s business manager of market development for Health & Life Sciences, and the company has 30 healthcare applications in its recently launched BlackBerry App World store.

During his presentation, Edward showed a slide of 12 mobile health companies that are “BlackBerry Solutions Partners,” which means they are clients of RIM to take advantage of the company’s marketing channels, developer know-how and more. Here’s a rundown of the 12 companies Edward counted as Solutions Partners and the mHealth buckets he put them in:


AllSportGPS — powered by Trimble — GPS-enabled mobile application for coaching on cycling, mountain biking, running, walking and other sports activities.

BonesInMotion – GPS-enabled app targeting those participating in outdoor activity 3 or more times a week: fitness walking, running, cycling, hiking, mountain biking, GeoCaching, and other outdoor activities.

BodyMedia – Wearable, “fashionable” body monitors that record and transmit a variety of physiological data to the BodyMedia’s website.

Healthy Lifestyle

Myca - Enables nutrition professionals connect with their clients through video consults, messaging, a personalized website, and a picture food journal.

Sensei - Makes mobile health applications for a wide variety of handsets, but most recently launched a couple of iPhone applications, including one for diabetics.

Personal Health Records

Tolven - Open source healthcare solutions developer of PHRs, clinician health records and health informatics.

CapMed - Offers PHRs for families to keep track of their own health data.

Corporate Wellness/Chronic Disease Management

t+Medical - Offers disease management and remote monitoring services that work with most mobile phones and also does some work with clinical trial management.

Medtronic - Develops medical devices and services to help people better manage chronic diseases.

Healthanywhere - Offers applications that let users monitor their health from a smartphone, PC or from a “dedicated Healthanywhere supplied platform.”

Confidant - Provides a mobile-phone based service that includes feedback, coaching and context to a patient’s chronic disease management routine, while simplifying and automating the flow of information between patients and their healthcare providers.

RIM also partners with chipmaker AMD for Corporate Wellness and Chronic Disease management.
