As a chain is as strong as its weakest element, so as the efficiency, flexibility, and robustness of a mobile network, which relies on a range of different functional elements and mechanisms.
Resource sharing among mobile network operators is a promising way to tackle growing data demand by increasing capacity and reducing costs of network infrastructure deployment and operation.
Mobile communication systems need to adapt to temporally and spatially changing mobile network traffic, due to dynamic characteristic of mobile users, in order to provide high quality of service.
D. 0. Reudink, in an unpublished work, has suggested a diversity system especially suited for mobile radio. In his system the transmitter sends a pilot wave along with the modulated signal.
The equipment described has been developed for general use in ground vehicles.
The error rates of MDPSK, coherent MPSK and noncoherent MFSK over slow flat, Rician fading channels are derived when linear diversity combining is applied to combat degradation due to fading.
In this paper, a new radiation pattern reconfigurable antenna is designed for mobile relay station (MRS) on vehicles to increase the link reliability and system flexibility in mobility.
We explore and contrast the requirements and various other factors that have shaped the technological evolution of public safety and commercial wireless systems.
This chapter presents technologies for managing mobile devices and subscriptions based on OverâtheâAir (OTA) methodologies.
Existing LTE macro cell networks tend to reach their limits of traffic capacity especially in dense urban areas, due to increasing numbers of mobile users subscribing for LTE based services.
