Fixed WiMAX Field Trial Measurements and the derivation of a Path Loss Model
نویسندگان
چکیده
Fixed WiMAX is an emerging and promising broadband wireless access system that is being widely deployed. Fixed WiMAX performance is boasted to outperform competing technologies, but is also doomed to be a short-lived hype. As little or no published material exists about measurements in real life field trials, we sat up a test bed and performed extensive field trial measurements. This paper present throughput results for the protocols UDP and TCP over fixed WiMAX. We derive a model for calculating the Signal to Noise Ratio based on the signal strength. A Path Loss model representing the measurements is derived and compared with well established path loss models for wireless access systems. Keywords—WiMAX Measurements, WiMAX Path Loss Model, WiMAX Throughput, Field Trial

Real Life Field Trial over a Pre-mobile WiMAX System with 4th Order Diversity
Mobile WiMAX is a promising wireless technology approaching market deployment. Much discussion concentrate on whether mobile WiMAX will reach a tipping point and become 4G or not. As a pre-mobile WiMAX system is being delivered, we decided to set up a real life field trial and perform the most important measurements over the system setup. The system was delivered with 4th order diversity. In th...

We review various ways to express the partition function of the single-band Hubard model as a path integral. The emphasis is made on the derivation of the action in the integrand of the path integral and the results obtained from this approach are discussed only briefly. Since the single-band Hubbard model is a pure fermionic model on the lattice and its Hamiltonian is a polynomial in creat...

The purpose of this study is to characterize the indoor channel for IEEE 802.16 (WiMAX) at 3.3 to 3.6 GHz frequency. This work presents a channel model based on measurements conducted in commonly found scenarios in buildings. These scenarios include closed corridor, wide corridor and semi open corridor. Path loss equations are determined using log-distance path loss model and a Rayleigh multipa...
