“…Because of these reasons, GSM operators must find feasible solutions. Network operators can enjoy significant cost savings while offering broadband wireless services that are comparable to 3G, namely, 3G-like services by integrating Wireless Fidelity (Wi-Fi) technologies [14].…”

The arrival of mobile phone also known as Global System for Mobile Communications (original acronym: Groupe Spécial Mobile -GSM) operators and their rapid growth may well be seen as one of the most significant developments in the field of communication and information technology over the last two decades. The aim of this study is to investigate the international transfer process of general packet radio service (GPRS) technologies, which supports the wireless access to external Internet protocol-based networks, and to propose a multi-criteria decision making (MCDM) approach to evaluate the alternative transferor companies. In order to achieve these purposes, firstly an in-depth interview was conducted with a purchasing manager of the third largest GSM operator in Turkey. Then, the major factors, which directly affect the success of a technology transfer (TT) project, are identified from the literature in order to determine the transferor selection criteria for a transferee company. The next step was to find out the relative importance of these criteria by asking the purchasing manager who was also a member of the GPRS project team. Finally, Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), which is a MCDM method, is applied to rank the alternative transferor companies.

“…For instance, Motorola is the largest holder with 27 patents [1]. Nokia (19), Alcatel (14), Philips (13) and Telia (10) are other largest holders of essential intellectual property rights (IPRs) [1]. However, operator giants such as Vodafone and Nortel, each have only one patent [1].…”

“…The scenario under analysis consists of a hierarchical network in which macro cells are WiMax cells and micro cells are UMTS cells. A GPRS/WiFi integration is studied in [10], but from the pricing standpoint, which concerns with resource allocation from an economic point of view. In [11], it is proposed a CAC scheme that allows Service Providers to manage the WiMax cell bandwidth between WiFi networks and its Subscribers Station (SS).…”

IEEE 802.16 standard or WiMax network is one of the new alternatives for broadband wireless access. Among its promising applications is the creation of a wireless backhaul support for WiFi traffic. In this context, it is mandatory to design a Call Admission Control in the WiMax Base Station for resource allocation for the integration of both network technologies. In this paper, we investigate this subject by proposing an optimal call admission control and resource allocation for WiMax and WiFi integration. The optimization problem is formulated as a Semi-Markov Decision Process. By presenting a comprehensive analysis, we discuss different design trade-offs alternatives.

“…Wi-Fi technology is mostly used in public places around the world. The Wi-Fi operators aggregate the wireless networks provided by micro carriers and provide a single access to the end users [3]. The coverage area of a Wi-Fi access point is low (in a room or in lobby) more over as it is working within public band so it broadcast weak signals to avoid interferences.…”
