Why Develop Mobile Database Applications?

November 27th, 2009



Mobile database applications are an effective way to streamline business processes and ensure that end users always have access to the critical corporate information they need to do their jobs. Although large enterprises tend to be the ones that invest most heavily in mobility, smaller businesses can also benefit from mobilizing their data.

“Mobile” is Not the Same as “Online”

Some people equate “mobile” to “online”, but they’re not the same thing. Online applications require a consistent and dependable network connection to an external server. Browser-based applications are the classic examples of online applications.

A truly mobile application, however, is an application that continues to work even when network connectivity is lost, unlike an online application. Being “disconnected” from the network does not stop the application dead in its tracks. This is an important feature for many users. Many mobile workers move in and out of network coverage on a regular basis while doing their jobs but need information to be “always available”. Online solutions don’t work well for these kinds of workers.

Local Data = Speed and Convenience

Mobile applications work best when they include some kind of local data store. By keeping important data local to the device, the user is insulated from network connectivity problems. Data operations are faster (no network lag) and can occur at any time. This results in a much better and less frustrating experience for the user.

Of course, using a local data store makes the design and implementation of the mobile application more complex. Even if the application works standalone, without the network, eventually some kind of data exchange must occur between the local data store and one or more external servers. Depending on the design of the application, keeping track of changes and dealing with potential conflicts can be quite challenging to manage. Mobile database applications often take longer and more skill to develop than their online-only equivalents because of this.

Saving on Network Costs

Besides offering a better user experience, mobile database applications can also yield significant savings in network costs. Data costs on mobile networks can be surprisingly high when using online applications, especially browser-based applications. The continuous back-and-forth between the device and the servers hosting the application racks up network charges quite quickly. A well-designed mobile application, on the other hand, requires only minimal use of the network by exchanging changes to data instead of entire data sets.

While the upfront costs of developing mobile database applications are typically higher than online applications, the savings on network costs can be quite substantial and make these applications must more cost-effective than their online equivalents. It’s certainly something to consider the next time you develop or purchase a mobile application.

Mobile Phones – Mobile Security

November 25th, 2009



The technology of mobile phones has become steadily more advanced, allowing us to utilise them in a widening variety of ways – including GPS navigation and the ability to surf the internet while on the move.

But with the growing popularity of ’smart phones’ for the purposes of internet connection and watching video clips, so the security risks usually associated with internet users are becoming more apparent.

Since 2004, there have been increases in the numbers of viruses that target mobile phones – which can be spread through malicious text messages and Bluetooth connections.

The effects of which can range from disabling phones and SIM cards to sneakily raising the costs of messages and phone calls. And with more of these handsets now becoming available as pay as you go mobile phones it can prove costly for those already on a tight budget.

Whilst the initial risk factor of the handset getting infected is relatively low, there have been reports of thousands of phones that have experienced problems. And according to a survey commissioned by a leading anti-virus software company – three out of four users expressed concerns over the safety of new mobile services.

Since it was discovered that operating systems on mobile phones were susceptible to viruses, firms have had to implement changes to try and bring the risk level down for their customers.

And with the launch of the next generation of smart phones announced at the recent Mobile World Congress, there is concern about potential security risks for these new open-source mobile phones.

Security experts from leading security software firms are warning of risks associated with using open-source software, which could leave mobile phone customers’ handsets at risk of viruses and worms in much the same way as computer users face today.

Cell Phone Signal Boosters

November 25th, 2009



Whatever type of cell phone you have there is always ways to improve it. Probably the most common complaint regarding cell phones getting a poor signal. Whether you live in an area that doesn’t have great coverage or your are traveling through the mountains you will always want a better signal. If you have an Apple iPhone for example you will want to be able to use all of it’s featured without being hampered by a poor signal.

A lot of people think that you have to live with a poor signal. After all, if the cell phone carriers don’t install any more cell phone towers in your area then the situation won’t improve. There is, however, a solution that you can use yourself and that is to invest in a cell signal booster. These are small chips that you place on the back of your phone and will have a massive impact on the signal you can get. Probably the most popular signal booster is the Wilson Cellular Amplifier which will keep working to give you a strong signal all day.

A great benefit that the Wilson Cellular Amplifier gives you is that you can still use your cell phone even if you are nowhere near a cell phone tower. It actually gives you full coverage for a distance of fifty miles. Typically this booster will give you double the signal as you would have without it. Using this booster can also make your battery last longer since your phone isn’t working as hard trying to lock onto a signal.

As your phone is tricked into believing that you are closer to a tower than you actually are you will see improved battery life. This is because the amount of power used depends on how far the nearest tower is.

One time that you might lose your signal is when you are traveling by car. Using the Wilson Cellular Amplifier with your iPhone greatly improves this since your signal is being amplified by an antenna that sits on the outside of your car. In fact this antenna is powerful enough that you could have a car full of cell phone users and each one would see an improved signal.

This particular booster is ideally suited to the Apple iPhone since it works on the GSM and EDGE technologies. If you are constantly suffering from a poor signal then simply attach this signal booster to it and you won’t have to suffer again.
