The Wireless World Research Forum has coined the vision of developing technology for ‘connecting 7 billion people with 7 trillion wireless devices by 2017’. The large amount of 1000 devices per human clearly is not going to be accounted for only by cellular technology, but a plurality of different wireless interfaces for a large set of different applications. Cellular dominated the wireless industry over the past 20 years. However, in digital cellular’s initial years cordless telephony was seen to be the volume driver, with cellular being more a niche application. Approximately 10 years ago the wireless local area network (WLAN) popped up as an important method for broadband cordless local connectivity. And as we can see from what is happening today, it has started to prove to be the door opener for broadband cellular to become widespread. So we see short-range cordless telephony and WLAN having paved the way for making people accustomed to using untethered communications. As the advantages of its use become apparent in a local environment, users want to have connectivity everywhere and start using the same service in a cellular wide area network (WAN).
