摘要： Improved techniques for characterizing, adjusting and optimizing the overall performance of a wireless network. In an illustrative embodiment, the overall network performance for a particular network configuration is characterized by a vector with two components, one representing network coverage and another representing network capacity. Network coverage is defined by the likelihood of service under load, including interference, and may be further weighted by traffic density. Network capacity is defined by an amount of traffic with a given spatial distribution that can be served at a given overall target-blocking rate. The overall network performance may be characterized using a two-dimensional capacity/coverage diagram which plots overall network performance vectors, each including a network capacity component and a network coverage component, for various network configurations. The overall network performance may be improved or optimized with respect to a given subset of network parameters by using an algorithm that proposes potential network configurations and evaluates them with respect to their overall network performance.

摘要： The device has a single strip having a first end, a second end, a length and a width. The first end of the strip is curved toward the second end of the strip to form a loop having a height. The length is approximately 10 mm, the width is approximately 5-8 mm, and the height is approximately 0.8-1.2 mm. The loop is preferably fabricated from copper. The loop is mounted directly to a test instrument such as a computer controlled impedance analyzer or network analyzer. The test instrument measures the inductance and resistance of the loop with no thin film sample placed therein, and then measures the inductance and resistance of the loop containing the sample under test. From these measurements, the device ultimately derives the permeability of the sample under test. The method for measuring the complex permeability of thin films at ultra-high frequencies includes the steps of recording the residual inductance and resistance for the loop empty; measuring the total inductance and resistance for the loop loaded with the sample under test; determining the change in resistance by subtracting the resistance of the loop without any sample from the resistance when the loop is loaded with the sample under test; determining the change in inductance by subtracting the inductance of the loop without any sample from the inductance when the loop is loaded with the sample under test; and calculating permeability.
