Mobile App Privacy Policy is a Smart Move
February 24, 2012 by Dan Zeck
There are many stories in the wires recently regarding protecting personal information. A reasonable approach to Personal information privacy is needed. Unfortunately, Government policy may be needed to enforce it.
I believe user trust in privacy policies is essential for mobile adoption to continue its growth trajectory, especially in business-to-consumer applications. However, privacy policy compliance should also be considered for employee based applications – since these employees are also citizens of countries that require data protection practices. At the end of the day, your employees are consumers first, and they are likely to have the same concerns in the workplace as they do at home. More than ever before, employees expect the same kind of experience at work as they receive in their personal lives – especially when it comes to mobile technology and privacy.
Many countries have had data protection laws on the books for years. However, they are not being enforced to a large degree. I expect that to change significantly in 2012. For example, the UK has had a data protection act since 1998. The EU has just recently – as of Jan 25, 2012 – drafted a new regulation for data protection that will supersede a prior policy. Awareness has tipped and the mobile industry needs to pay attention to these laws and policies at the price of losing subscribers and users.
What type of information requires protection? There’s a term for this – Personally identifiable information (PII): Your identity, location, network address, payment info, phone numbers, vehicle tags, driver’s license number, date of birth, birthplace, national ID numbers, and more. The current definition of PII does not address social network concepts so add to that list your social “friends” and their PII. You can certainly understand how this data protection issue grows exponentially with the advent of cloud-based social apps and networks. In the news just recently several social services, like Twitter and Foursquare have been caught gathering user contact info from their devices without direct consent of the user. This has since been addressed to a degree but it’s a great example of the issue.
Device vendors, social networks, content providers, carriers, app developers and enterprises all have a role to play to protect consumers’ personal information. I agree that this is required but a reasonable approach must be taken that provides sufficient protection and consumer awareness but is not “heavy” in terms of government regulation and compliance.
There’s a balance point here that the major industry players and government agencies must define and agree upon. I applaud the recent Apple, Google, Microsoft, Amazon, HP and RIM agreement with the AG of California.
And at Antenna, our platforms will continue to be compliant with the emerging policies across the globe.
The Door Closes on Mobile Flash, Opening Greater Opportunity for HTML5
November 17, 2011 by Dan Zeck
You know the saying, when one door closes, another one opens? In this case, the door for HTML5 was just kicked open a little wider. Last week Adobe announced it would be abandoning mobile Flash, a move that the late-Steve Jobs would certainly endorse. This also signals a trend we’ve been following and advocating for a while – HTML5 is making great headway over the competition.
And in my opinion, HTML5 is making great progress. HTML5 is getting richer and richer, and as mobile web standards evolve and the UI for mobile web apps gets better, it’s becoming increasingly difficult to differentiate between web-based HTML5 apps and native apps. On top of that, it’s less expensive to build a mobile HTML5 app instead of several native apps, and the web development model saves time for developers who don’t need to write in several languages. There is also more to come with the future of mobile web apps, including inter-app messaging, better UI animations and background script processing provided by web workers.
Further, HTML 5 video (webM or H.264) will provide a better than sufficient mobile user experience and as hardware and devices continuing to be ship with faster CPUs and high performance memory, the experience will improve even more.
Mobile Mastery: Nokia and Microsoft a Tale of Two Ecosystems
October 26, 2011 by Dan Zeck
Users have their heads in the clouds.
When Nokia announced they were signing up with Microsoft in February 2011, the mobile world gasped. Could it be that the world’s number one handset manufacturer was signing on with Microsoft and dumping Symbian and the fresh air that was Moblin + Maemo > MeeGo? It happened. Wow!
The engineering teams inside Nokia no doubt went through some serious soul-searching trying to find a way to make the Microsoft OS “fit” into their development culture let alone their emerging devices and ecosystem, which was not a simple undertaking. They announced product today and ecosystem updates – good stuff!
The question is: will it be good enough? The world has moved on and a few months is a long time in this fast-paced market. Can Nokia regain lost market share with previous users? What about new users? Will they come? Why will this be so difficult? Apple has great devices with more to come, a killer feature set in iOS 5, an amazing marketing machine and the leading mobile media ecosystem. Android is making big strides and has locked-in the number two position with a strong ecosystem and many hardware suppliers. The proverbial user-expectation “bar” is set high.
Mobile Mastery: Phone Call – iPhone 4S or 4G for AT&T?
October 13, 2011 by Dan Zeck
Heard on the net recently: AT&T might label the iPhone 4S as a 4G phone? Really? The purists cringe.
I find this amusing in a technology vs. marketing sort of way. AT&T is competing hard with Verizon on 4G coverage. Verizon is winning in terms of deployments and AT&T’s Mobility Leadership admitted it. AT&T claims to have faster speeds in 4G tests vs. Verizon; this is very regionalized and subject to many network conditions – channel bandwidth, encoding schemes and antenna usage.
The question is what does 4G actually mean and when did 3G end and 4G begin? It’s all a little gray… and was made worse when the ITU reversed a decision in December 2010 and stated that HSPA+ was a 4G technology even though it preceded LTE by years.
The iPhone 4S does have an HSPA+ enabled radio on the AT&T network. HSPA+ was defined in the 3GPP Rev 7 spec in the 2006-2007 timeframe. LTE was defined in the 3GPP Rev 8 spec in the 2008-2009 time frame. Many believed that the Rev 8 spec was where the 3G and 4G boundary was. That is, until the ITU changed its mind.
Some in the technical community suspect that the iPhone 4S lacks a few current technical enhancements to make it real 4G (e.g. 64QAM encoding in both the uplink and downlink). We will soon find out as the phones are shipping now and no doubt detailed test results will appear on the net.
The bottom line: this is way too complex for consumers to understand.
As for coverage maps, see for yourself:
AT&T HSPA + map
Verizon LTE map
This is one reason why AT&T is pursuing T-Mobile – to expand their HSPA+ network.
Today’s carrier networks are evolving and the features required for the highest throughput are not available everywhere creating a situation where marketing hype will thrive – let the carrier 4G battles continue.
A 4G label on the iPhone 4S is a stretch in that it’s not real 4G based on what networking purists believe. However, given the ITU’s reversed decision in Dec 2010, it is sort of true…and clearly gray.

Geek Speak:
AT&T 5MHz/channel HSPA+ and Verizon’s 10MHz/channel LTE can be roughly equivalent throughput-wise IF (the proverbial big “IF”) favorable radio conditions exist and IF AT&T uses certain networking techniques (e.g. channel doubling, 64QAM and 2×2 MIMO). One wonders what 64QAM and 2x MIMO are. 64QAM = 64-bit quadrature amplitude modulation – basically how analog and digital signals are converted to symbols for transmission. MIMO is Multiple input, multiple output. Contrasted with MISO – multiple input single output, not the soup! and SIMO – single input multiple output. 2×2 MIMO is 2 transmitting antennas and 2 receiving antennas effectively doubling the throughput on a point-to-point link. You may recall Apple talking about using two antennas in the iPhone 4S. Is this MIMO on the device side? We will soon find out.
