Mobile IT - commodity or value add?

Should I pay or should I go?

Choosing a cloud hosting partner with confidence

Analysis Cost or complexity. It seems a bit of a Hobson's choice, but for those who have to foot the bill for the increasing business use of communications on the go – mobile phones, mobile email gadgets, and ever-connected laptops – it's a decision that increasingly has to be made. Keep it simple and pay more, or deal with a maze of alternatives and pay less.

The cost of making mobile phone calls, especially while roaming in other countries, has recently been in the news, and research from business and IT analyst Quocirca has consistently identified cost as a major impact on most business' thinking about mobile telecoms.

In the company's most recent study, around four out of five enterprises cited national and roaming call costs as the two most important considerations in negotiating contracts with operators.

Sure, we all worry about cost, but the more positive news for the telecoms suppliers is that the use of mobile technology has moved to become more strategic.

With pilot projects and trials extending into full scale deployments, mobile applications are becoming part of normal business strategy and funded from the regular IT budget for the majority of enterprises. This also means increased competition for resources – both people and budgets - as IT departments are not exactly flowing with spare capacity.

We know from previous research into IT buyer behaviour that, for most organisations, the finance director will have the final say on whether a project will go ahead, so value for money becomes an important criterion.

This financial view, rather than pure interest in technology has driven a lot of interest in two recent technology bandwagons – Wi-Fi and Voice over Internet Protocol (VoIP) – but for slightly different reasons.

The use of wireless LANs has been very difficult to justify in most working environments, except in places where cabling is difficult, such as some conversions to offices or listed buildings. After all, most users would need to sit still somewhere to use even a laptop, and would probably need to plug in for power. Wireless connection also once required a plug-in PCMCIA card – an expensive proposition for every laptop.

Things have changed significantly outside the office, and Quocirca's research has shown a marked movement towards the business use of Wi-Fi.

The addition of wireless into basic laptop functionality, fuelled by Intel's Centrino marketing, the arrival of low cost wireless routing to rapidly growing broadband connectivity has made wireless technology more affordable and better understood.

The growth in competition among public hotspot providers is now bringing connectivity costs down, and charges are more obvious by the minute rather than by the megabyte, something cellular operators are only just starting to pick up.
