The operators face a lot of different challenges, like the necessity for differentiation against competitors, provision of service variety and quality. They permanently have to deal with price and cost competition. In order to succeed in that market the operators demand new products from the suppliers leading to new strategies. The authors discuss the development of GSM from the market point of view.
