How did the Internet - a revolution in inclusiveness and understanding - turn into a tool for governments spying on citizens. In most countries ISPs are obliged to cooperate with the local government and provide details of who was browsing under what IP address. - Source: Communications Engineer, Volume 5, Issue 5, p. 26 –31

VOICE OVER INTERNET PROTOCOL (VoIP) services that promise higher audio quality, richer feature sets and potentially lower cost are attractive to both end-users and service providers. Users can enjoy voice within an extended communications suite, and service providers can mix voice with other IP services to make their offerings more compelling to the user. While VoIP services have traditionally been consumed within the home or office environment, it is desirable that they continue to be available when the users are on the move, particularly at hotspots. - Author(s): T.

The high power consumption of 3G infrastructure is proving to be one of the most significant problems facing the wireless industry today, not just because of the rising cost of energy but also because the heat dissipation of the power amplifier (PA) is a limiting factor to making smaller, lighter and cheaper basestations - and the environmental impact of deploying large numbers of power-hungry basestations is becoming increasingly unacceptable. - Author(s): J.

At the 2005 GSM World Congress in Barcelona, the telecommunications world was introduced to the concept of fixed-mobile convergence (FMC), which is the ability to seamlessly transition calls between unlicensed Wi-Fi networks and licensed carrier networks. Based on the 3GPP/3GPP2 IP multimedia subsystem (IMS) network architecture standards, FMC was touted as a hook to lure consumers and enterprises away from the incumbent cellular providers to landline-based Wi-Fi service providers, or for integrated carriers to stay competitive against the emerging Wi-Fi service providers. - Author(s): T.

We might think we all know our vital statistics - conveniently, often provided for us by the cellcos themselves - but how do we know they are accurate, or that they are the right measures to tell us how healthy the cellcos' businesses are? How can we identify the characteristics of a healthy wireless business and what the next-generation key performance indicators will be? The answer is, of course, all down to vital statistics: each time a new phone is switched on, or a call made with a new SIM card, Vodafone can register a new customer acquisition and keep them on its figures for three months even if the phone or SIM card is only used once. This provides a temporary boost to subscriber numbers, and the company may also hope that some of these accounts will remain active. - Source: Communications Engineer, Volume 5, Issue 5, p. 42 –43

What do people look for when shopping for a new mobile phone? Nowadays, for the average person this isn't just a question of mega pixels and memory, but style. Mobile phones have become fashion accessories, something new to flash out of a handbag, or even to match a piece of jewellery. With celebrities now sporting diamond encrusted phones, it's not surprising the major OEMs feel the need to keep up with the dictates of fashion. Because when it comes to selling mobile phone handsets, design is just as important as technology. - Source: Communications Engineer, Volume 5, Issue 5, p. 44 –45

Fixed-mobile convergence (FMC) has become one of the major topics occupying mobile and fixed line service providers in recent months. The concept could result in significant changes to the way in which mobile and fixed line operators work, bringing both services together so that users can experience the best service and lowest costs for any given situation. - Source: Communications Engineer, Volume 5, Issue 5, p. 46 –47
