Dolphin 7600 - Mobile Handheld PDA

MoblileDataforce focuses on providing mobile software applications, so when hardware companies develop handheld computers that match our focus I am very interested. Hand Held Products (HHP) has recently released a new handheld computer called the Dolphin 7600. This handheld is small, light weight, has extended battery life and a built-in bar code scanner. I particularly like the rubberized edges for easy gripping and added drop protection. It has a 4 foot drop to concrete rating.

It runs on the Windows CE operating system so is completely supported by mobile software applications and mobile software platforms like the PointSync Mobility Platform.

This category of handheld computers (light industrial mobile handheld computers) fits field users who need a mobile computer that can easily fit in their pocket, or on their belt. Something that is easy to handled, but contains all the functionality of the larger industrial handheld computers.

RFID Solutions on Handheld Computers and PDA at MobileDataforce

Last year at this time MobileDataforce was receiving a lot of questions from companies asking about RFID for use on mobile handheld PDAs and rugged handheld computers. They wanted to know what was possible with RFID. It was an educational process, rather than a buying process. I am happy to say (as the CEO of a software company) that companies are now buying RFID solutions. Today we are involved in numerous RFID solution implementations and projects.

We have implemented RFID ear tags on cattle, we have implemented a number of asset tracking applications, and now we are reviewing a project to add RFID tags to shopping carts. How interesting!

Symbol MC35 - More Smartphones and Handheld PDAs

Ninety-one people looked up Symbol Technologies' MC35 yesterday on Google. That is quite impressive for a new handheld PDA from Symbol. This device includes a phone, Windows Mobile OS, GPS, keypad and much more in a semi-rugged form. It is larger than most consumer devices running pocket pc, but a perfect size for industrial use.

Symbol/Motorola has been rapidly releasing new mobile handheld devices intended for the "mobile" category of workers. The true field services worker who does not want to pack around a large and heavy industrial handheld computer.

Warnings for Companies Considering Mobile Handheld PDA Business Solutions

MobileDataforce is very busy these days helping companies replace old mobile software solutions for handheld PDAs that were based on out-dated Palm or Pocket PC operating systems. Although we appreciate the business, it is worth highlighting this issue for companies considering whether to program/code their own mobile software solution, or use a supported mobile middleware platform like the PointSync Mobility Platform.

Here are some issues to consider:

1. Is your mobile solution going to be upgraded every year as mobile operating systems and handheld computers are upgraded?


2. Who is going to be your in-house expert on the latest mobile operating systems and how to support them? It will take an investment of resources to stay current.


3. When you buy new handheld computers or PDAs, they are generally sold with only the latest most current operating system on them. So how can you buy new handheld computers, unless your mobile solution can run on the latest operating system. Over the life of your mobile software application you may need to upgrade the OS many times.


4. Often a business unit funded the original mobile software application development project. Are they willing to continue funding your mobile operating system upgrades each year. The answer is most often NO! So how can IT support it after the first year?


5. One solution to prolonging the life of a mobile software application is to pre-purchase all the handheld computers or PDAs you will ever need. This will ensure that you have the supported hardware and supported operating system available to you over the life of your mobile software application. But let's be real....who is going to fund a pre-purchase of all the hardware you will ever need? No business unit I have ever met. If you find one, let me know...I would like to sell them all the mobile software they will ever need in the future as well.

The most reasonable approach to keeping current with mobile operating systems and the latest handheld computers and PDAs is to develop your mobile handheld application on a supported mobile software platform like MobileDataforce's PointSync Mobility Platform. Why? MobileDataforce and other companies that author mobile middleware and mobile development platforms committ to keeping them current on the latest supported operating systems - so you don't have to. The cost of the operating system updates/upgrades are generally covered in your annual support contract. Companies like MobileDataforce employ legions of software developers who are paid to be experts on mobile operating systems and how to keep mobile middleware and mobile software platforms current and updated.

Mobile Clinical Assistant and Inspection Software

One of our customers selected the "Mobile Clinical Asssistant" to use with their mobile inspection software solution. This is an interesting Tablet PC that can come integrated with a barcode scanner and a digital camera. I love the built-in handheld and sealed environment for easy cleaning.

SoMo 650 Socket's New Mobile Handheld PDA

Here is an interesting development in the world of PDAs and bluetooth barcode scanners - Socket, a company that traditionally manufacturers accessories and add-ons for other company's PDAs and handheld computers, has just announced their own PDA called the SoMo 650.

This is an interesting development since sales of stand alone PDAs (those without phone capabilities) have been dropping year-over-year in favor of PDA Phones and Smart Phones (PDAs running on Windows Mobile and other powerful operating systems that included integrated phone capabilities). It will be interesting to see how a new PDA without phone capabilities will sell these days.

I also wonder how this will impact Socket's sales of their bluetooth barcode scanners and other accessories. Other PDA manufacturers will naturally want to avoid referring customers to them out of fear that Socket will sell them the SoMo 650 rather than their iPAQ, XDA, MC35, MC50 or MC75.

Symbol Technologies, Intermec Technologies and many other handheld computer makers are rapidly downsizing handheld computers and releasing smaller versions, but most have integrated phones. These companies have often referred business or resold Socket products...hummmm. They will be very wary of Socket going forward.

Socket must believe they can make more profits by selling PDAs than not. So let the games begin!

How to Develop a Slow and Unreliable Mobile Software Solution for Mobile Handheld PDAs and Smartphones

Some companies have figured out how to develop slow and unreliable mobile software solutions for use on expensive and fast handheld PDAs and smartphones completely on their own, but for those new to this process please read on:

1. Make sure you purchase the slowest available processors on your handheld PDAs


2. Develop your mobile software applications in complete isolation from your real world working environment - chance and fate make life interesting if not entertaining


3. Make sure you purchase the least amount of memory possible on your chosen PDA


4. Purchase outdated and end-of-life handheld PDAs (try eBay)


5. Develop new mobile solutions to run on old operating systems (try pocket pc 2002 or 2003)


6. Choose a dial-up modem option for synchronizing your PDA (forget wireless broadband)
7. Develop mobile solutions that assume you will always have good wireless carrier coverage
8. Make sure if you lose wireless coverage, that your mobile software application is useless


9. Take your existing desktop server application and force it to run on your PDA


10. Don't filter the data you want to synchronize from your Oracle or SAP databases, just download the entire corporate database to your handheld PDA
11. Don't synchronize only "changed" data, download the entire corporate database each time you synchronize
12. Make sure if your connection is broken, you start the entire synchronization process over again - none of this starting where you left off sissy stuff
13. Don't consolidate your enterprise data into one simple mobile synchronization "view", leave the data in dozens of different databases and database tables spread liberally around your IT ecosystem - this proves your courage and fortitude


14. Don't bother optimizing your application for mobile environments


15. Maximize the amount of encryption and security you use on every aspect of your mobile solution - with enough security and encryption you can slow the data synchronization down to a mere trickle


16. Make sure you have all your mobile workers synchronize their handheld PDAs at the same time in batch mode


17. Hard code your mobile software solution to work only on one specific handheld PDA that can only synchronize with your backend database in one specific manner


18. Ensure that the software programmer that develops your mobile software application is ambitious and feels he/she is under paid and under appreciated, and/or their green card is about to expire


19. Develop your own synchronization middleware...so what if other software companies have spent the last 15 years perfecting it...no time like the present to begin your own 15 year odyssey.


20. Make sure this is your first time developing a mobile software solution - it brings out the pioneering spirit


21. Give yourself some unrealistic development time frames - make sure you commit to these time frames publicly and in the presences of senior management. Make sure that senior management then develops their business strategy around the dates you provided


22. Don't include testing and debugging time in your project plan...you need to cut corners somewhere
23. Documentation is only for forgetful minds, don't waste your time here


24. Purchase all your handheld PDAs before you develop your mobile application. Purchase enough to last the next 8 years. Who knows how long they will be available on the market and you don't want to re-develop your mobile software application for new operating systems and features


25. Allow your mobile workers to download all the games, music and videos they want onto their handheld PDAs


26. Don't standardize on a particular operating system or handheld PDA specification - it will stifle creativity

Handheld PDAs in the Kitchen

I took a brief holiday with my wife this week and somehow ended up in a kitchen products store. As I was rummaging through the various over priced multi-colored utensils from around the world, I noticed a Symbol Handheld PDA on a nearby kiosk. This was something interesting in a kitchen store, who would have thought it?

I walked over to the kiosk and noticed a synchronization cradle sitting next to a connected desktop computer with a flat panel monitor. I noted that the Symbol PDA had a built-in barcode scanner, monochrome screen and was running the Palm OS. I walked slowly around the kiosk, pretending to be captivated by the flexible cutting boards, but I was really trying to determine the purpose of the handheld computer. I noted that the Symbol PDA was their low-end ruggedized device, and that it seemed to be positioned for the use of their customers, not for their own internal inventory purposes. I imagined I was Sherlock Holmes out to solve a case and reached for my pipe.

I nonchalantly picked up a wooden spoon with a price tag of $49 and pretended to be fascinated by its craftsmanship. I looked closer at the kiosk and noted a sign mentioning the registration of gifts. That's IT! The Symbol PDA was used by people wishing to create lists of over-priced gifts, they would never think to buy for themselves. They would scan the barcodes on all the exotic wooden spoons and then synchronize the list to the kiosk computer. Once the products were in the database application, anyone could access this list over the internet. Wow! So much technical ingenuity from a kitchen supply store!

I best finish blogging and return to carving wooden spoons.

Crop Dusters and Mobile Handheld PDAs

I am always interested in new and unique mobile software applications that run on handheld PDAs and smartphones. This week one of our partners in New Zealand started work on a flight information recording application for crop dusters. They are using the PointSync Mobility Platform to design, develop and deploy this solution. I don't know all the details, but it certainly sounds interesting!

Building Inspection Solutions on Handheld PDAs

It is the season for Building Inspection solutions here at MobileDataforce. We are currently involved in 5 different Building Inspection projects. We are working with county governments, private building inspection companies, mold inspection companies, water conservation organizations, and a housing authority in Europe.

There are a lot of similarities:

• Identify the building and building owner
• Identify the physical location
• Identify the inspector
• Identify the date and time of the inspection
• Inspect the premise
• Identify and document the areas that were examined - building, floor, room, wall
• Recommended action steps
• Inspection Report
• Mobile Invoice

Sometimes there are work orders or preventative maintenance work orders that get activated based upon an inspection. For example - NE corner of the roof is damaged, schedule repair. Other times work and cost estimates are associated with the inspections. For example - NE corner of the roof is damaged - estimated repair time 16 hours - materials costs $345.

We often support the mobile component of existing database applications for Building or Property management, but other times we develop both the mobile component and the enterprise building management application.
