Cable is on the retreat. In almost every data application, one form of wireless networking or another is supplanting copper and fibre, whether in the last few metres with personal area networks or in the ‘last mile’ with WiMax.
The key technology areas – mobile phone networks, wireless lan and short range, low bandwidth methods of transmission such as Zigbee – are becoming pervasive. So, what levels of adoption are they achieving and what are their chief uses in industry?
Mobile ’phone based remote monitoring and control benefits from wide areas of coverage and bandwidth ranging from a few kbit/s on GSM networks to a few Mbit/s with 3G. In many applications, sheer bandwidth is not necessary and effective monitoring and control networks have been built which capitalise on mobile networks’ ability to cover wide areas of the countryside.
