Mobile Computing Essentials

February 10th, 2021

Mobile computing is the ability to do computing tasks in some or all possible locations. Here, I’ll be listing (in my opinion are) the top 4 requirements for mobile computing and my suggestions/opinions on those requirements.

There are other requirements for mobile computing, and you can check them at Wikipedia.

Portability

It’s common sense: if your computers or mobile devices are too heavy to carry around they are useless for mobile computing. Gone are the days of lugging around heavy laptops the size of attache cases. A good example of a very portable computing device is the Apple MacBook Air: It’s small and thin enough to put in an envelope. Also good examples are the humble netbooks. These small, almost pocket sized computers are small and light enough that you can almost put them inside your coat pockets or purses. They offer relatively good processing power for the basic computing needs, up to 15 hours of battery life (depending on use) and are cheaper than most full size notebooks. Since Asus came out with the original Ultra Mobile Personal Computer (UMPC), the EEEPC, almost all computer companies have created their own netbook line.

Now, with the release of the Apple iPad tablet, Tablet Computing have been put in spotlight again. Major computer brands are following with Samsung releasing the Galaxy Tab and HP developing and hopefully finally releasing the Slate, and Asus announcing the EeePads, that more than out features and out powers the iPad.

Battery Life

Even if you have the fastest and lightest computing devices (laptops, mobile phones, tablets, etc.) but you don’t have enough power to support them, they are practically useless for mobile computing. A couple of hours of power is the current standard for most laptops. If your laptop’s battery last for three hours that’s already above average.

With netbooks, three hours is just the average. Because of the development of low power consuming processors and LED displays, and also the development of higher capacity, compact lithium ion/ polymer battery packs, we have netbooks that can stay powered for more than 8 hours. Example of such laptops are the next generation Acer Aspire One 533, ASUS Eee PC 1015,MSI U160, HP Mini 210 Series. Imagine this scenario: You fully charge your netbook before you start the day and then use it unplugged for the whole day. Now that’s you call “truly mobile computing”. With smartphones, especially those that utilizes a lot of 3G connectivity, a full day of operation is adorable: anything less is just normal.

Internet Connectivity

Staying connected to the Internet is one of the basic requirements for mobile computing. Unless you don’t have any use for the Internet, your mobile computing device should at least have a built-in wireless network adapter, also known as wi-fi card. Another essential device for staying connected with your netbook or laptops is a mobile broadband device like the 3G USB modems, pcmcia cards, and built-in 3G modems in several netbooks and laptops. The latest smartphones take full advantage of 3G networks: they can work outside wi-fi hotspots. The only downside to that is the rapid loss of battery life.

Durability

Mobile computing has the most demanding requirements for devices especially when it comes to durability. Because mobile computing is done anywhere and everywhere, the devices you use should be able to survive the most number of scenarios. And when we talk about durability in mobile computing, nothing beats the Panasonic ToughBook. This line of laptops from Panasonic were designed to handle the most demanding computing environments. Check out the videos in Youtube.

Tips

Before buying any mobile computing device, make sure you research well about the product. The best way to gauge if the device meets your needs and wants is to try the actual device. If you can try the device for a day, the better.

Always buy mobile computing devices with at least one year warranty. That gives you a small sense of security when your device fails within the first year.

When it comes to durability, most mobile computing devices like laptops, netbooks, smartphones, and tablets have operational guidelines that you should follow. If you use these devices outside their perscribe conditions, you risk voiding the warranty. Examples are using the device under the rain, vibrating platforms, sand-prone and water-prone places like the beach, and other uncommon locations.

Electronic Evidence Discovery May Shift To The Mobile Computer Forensic Specialist

February 10th, 2021

As the computing world advances and especially as the world of the wireless computing advances, there are certainly going to be instances where the services of a mobile computer specialist will be required.

The mobile arena now includes hand-held devices with comprehensive capability, in fact there are many more wireless units than desktops.The complexities of today`s wireless units such as iPods, iPads, Smartphones and tablet computers now have the same computing power of PC`s that were manufactured within the last decade. With cutting-edge technology such as infrared and bluetooth now integrated in to mobile computers, the advances in mobile computing are rapidly surpassing those of the desktop computer.

The hand-held device now includes a wide variety of units and can include video cameras, iPods,digital recorders or any hand held units.Mobiles may differ from the desktop computer in the way that they operate. The mobile computer forensic field now shifts from hard drive recovery to electronic evidence discovery of hand held units.

The mobile operating systems and hardware standards may change more frequently as new advances are introduced. New versions may be introduced several times within the product year, whereas computer software, may be revised annually or bi-annually. There are many different platforms in the wireless computing arena which makes the job of the mobile computer forensic specialist even more challenging and additionally, there may be variations within each communication technology. There are several variations of the 802.11 which is the standard used by all wireless networks. Shorter range wireless communication involves the use of Bluetooth, while within even shorter ranges, communication is handled by the infrared light waves.

Mobile computer forensics does not only involve mobile phones and the approach is not yet standardized due to the rapid advances and multiple operating platforms. The main reason for the state of affairs is that many manufacturers are pushing different standards in hardware, interfaces, operating systems and protocols. As a result, mobile forensics cannot be treated in the same way as static computer forensics, even though the concepts, may appear to be similar. The mobile forensic specialist job may rely less on technology and more on skills, procedures and problem-solving ability and the approach can be different.

Perhaps the most important forensic component of the mobile phone would be the Subscriber Identity Module card which is used to authenticate the user and verify the services. Alternatively, this information can be embedded in the phone. Forensic information may also be available in external Secure Digital cards that can be used by most mobile devices.

The mobile forensic field is primarily concerned with the acquisition of mobile phone data and there are tools, both hardware and software. Another challenge for the mobile forensic specialist is to keep up with the avalanche of changes in the mobile computing industry. Mobile forensic software may behind the curve with regard to the new mobile technologies and you should be aware of the various tools both forensic and non forensic that can be used.

The new burgeoning field of mobile arena is sure to offer satisfying available opportunities and challenges for the mobile computer forensic specialist.

The mobile computer segment that includes notebooks, netbooks, tablets and other hand held devices, now easily surpasses the desktop PC market in market size.
