MM-Wave Planner Antenna For Wireless Communication

Abstract

The expectation of end users for and data allowance puts pressure on network operators in meeting demand and leads to requests from operators for access to greater amounts of spectrum. Making spectrum available to meet the future requirements of mobile broad band services is complex as prime spectrum for mobile broadband services is also access to services exhibiting increased speed heavily utilised by other services and is a scarce resource. Communications regulators must consider the impact on existing spectrum management arrangements and incumbent users. When making further spectrum available. Some of the issues to be taken into account , 1. Determining when the effect of making spectrum available for mobile broadband services is no longer the highest value use as this may preclude other uses of the spectrum with inherent public benefit. 2. Considering whether greater spectral efficiency can be achieved by network operators in existing spectrum holdings. 3. Considering whether the needs of incumbent users of spectrum can be balanced with the future spectrum requirements for mobile broadband services. The global bandwidth shortage facing wireless carriers has motivated the exploration of the underutilized millimeter wave (mm- wave) frequency spectrum for future broadband cellular communication networks. There is, however, little knowledge about cellular mm wave propagation in densely populated indoor and outdoor environments. Obtaining this information is vital for the design and operation of future fth generation cellular networks that use the mm-wave spectrum. In this paper, we present the motivation for new mm -wave cellular systems, methodology, and hardware for measurements and offer a variety of measurement results that show 28 and 38 GHz frequencies can be used when employing steerable directional antennas at base stations and mobile devices.
