tailieunhanh - The Role of Connectivity in Next Generation Wireless Networks

What does the wired portion of a next generation wireless network look like? The better question is this—what does the wired portion of a next generation wireless network look like at specific points in time: one year, three years, seven years from now, and so on into the future? That question is hard to answer because migration to next generation networks is an evolutionary process. | The Role of Connectivity in Next Generation Wireless Networks The Role of Connectivity in Next Generation Wireless Networks What does the wired portion of a next generation wireless network look like The better question is this what does the wired portion of a next generation wireless network look like at specific points in time one year three years seven years from now and so on into the future That question is hard to answer because migration to next generation networks is an evolutionary process. Evolution is more than change. It is constant change. For wireless service providers evolution implies a stepwise process of network migration a process driven more by subscriber demand and operational efficiency than by a build-it and they will come strategy. In today s business climate progression to next generation networks is driven by several factors. Improve quality of service. Subscribers have higher expectations for wireless services. Quality means better coverage fewer dropped calls and transparent billing and roaming. Quality also means higher speeds to support new spectrum-hungry data video and multimedia service offerings. With churn rates as high as 30 in recent years and evidence that suggests higher speed wireless data subscribers will generate more than three times the revenue of voice-only subscribers quality of service clearly drives earnings. Improve operational efficiency. Service providers face high fees for 3G licenses mandates for 3G service availability and limited handset availability that delays deployment of advanced services. Still one of the biggest items in the budget is network operations. As the network grows and becomes more complex wireless service providers must improve operational efficiencies. Areas such as service monitoring troubleshooting fault isolation and repair must help to reduce costs. Increase revenue. The promise of next generation networks is to reduce churn earn new subscribers and increase average revenue per user ARPU
