Read about Biometrics on Mobile CE Devices in my article in the February/March 2006 Issue! It's on the shelves now!
MobileVoiceRTP Supports Real Time Video!
Pushing full color video packets across in real time did not provide full motion capabilities when using 300 to 400 MHz Mobile CE devices. RGB cameras in 565/24 bit and 555/16 bit suffered the constraints of both the hardware and bandwidth. With that in mind 8, 4, 2 and 1 bit resolutions were developed and full motion results were achieved with lower bit widths. The maximum clock speed seen with Mobile CE devices at present is roughly 625 MHz, which is no where near the 2 to 4 GHz clock speeds of laptop and desktop devices.
While one bit resolution is grainy and resembles animation, it provides enough detail to merit incorporating this functionality into this Videophone. As time progresses and the clock speeds increase, full motion duplex video streams in high resolution color will be possible.
MobileVoiceRTP is a real time streaming voice product which provides some unique features making it highly interoperable on all existing Mobile CE Platforms including Palm, Pocket PC, H/PC Pro, HPC 2000, Pocket PC 2002/2003, and CE.NET. (sorry Smartphone platform)
* You must have an 802.11 Access Point, a
Router and DSL or a Broadband Connection, Internet access is required.
** Ipaq 3700, 6300, Photosmart SDIO, video supported.
*** The newer 625 Mhz devices may support full motion color video, we can't wait to try.

Using Free Dynamic DNS Services for VoIP
You can set up devices to use dynamic DNS services for web servers, cameras and VoIP use. For cameras visit http://www.viewnetcam2.com/ip_ddns/ . For web servers, VoIP etc. visit http://www.dyndns.com/services/dns/dyndns/
Edu-taining reading, if you have broadband or DSL, pick this
book up! Picture this, with a initial $35 to $70 investment to purchase a
generic ATA (Analog Telephone Adapter), you can then run your regular phones
over VoIP, a nice way to tunnel your 5.8 Ghz phones over the internet. The
O'Reilly series of hacks books describes clever ways of implementing and
deploying various technologies, using "hacks" not in the modern sense i.e. "a
poor job done", but in the older one of where ingenuity and creativity solved
the tasks at hand. This particular book covers 100 projects with VoIP
technologies. Topics are; broadband VoIP, desktop telephony, skype, asterisk,
hardware phones, navigating/analyzing VoIP, and deploying VoIP systems. This
one will arm you with enough information to setup your own telephony server,
PBX etc. all at the cost effective price of a generic PC.

The Pocket PC Camera API in CE 5.0
Generalized Camera APIs for CE 5.0 are available. These enable you to take still pictures (JPEG) and video clips (MPEG4, H.263). The Camera APIs are now part of the standard CE version 5.0 and beyond. For a description of the APIs go to the API Page The Windows Mobile 5.0 Pocket PC SDK comes with sample programs utilizing the camera APIs and are written in C++, VB or C# for VS 2005 .NET. You can download the Mobile 5.0 PPC SDK via this link to the Download Page .
Pro Service Oriented Smart Clients with .NET 2.0
SOA with Smart Clients, some interesting reading. Smart Clients
are not only Mobile applications but are adaptive applications which can
operate in either a connected or disconnected (buffered) mode. The are roughly
three categories for Smart Clients: Windows Forms SC, Windows Office SC, and
Mobile SC. Under Office Smart Clients fall into two sub categories, those
developed with VSTO Visual Studio Tools for Office and IBF, the Information
Bridge Framework. VSTO SCs work with Word and Excel and allow one to embed .NET
assemblies developed with Visual Studio into these documents. IBF focuses
integrating Line of Business documents developed with Word, Excel, Outlook
or InfoPath with Web Services which are developed with Visual Studio.
The book covers other aspects of SC's such as No Touch or One Touch
deployment. In a nutshell Smart Clients usually are updated via HTTP
over the web, but operate as a Fat Client providing the ability to
If you have short term to project length development requirements, consider utilizing our hardware and software development skills which cover a wide variety of areas. Programming languages include: C++, C#, Java and assembly. Environments are typically the Windows CE or XP Operating Systems. Specific areas include:
