  • 700 Mhz Base Station Test Results for the FCC
    MOBILE --------.. BEFREE 0---.- 700 MHz Base Station Test Results for the FCC Flow Mobile 700 MHz Base Station Test Results 1.0 Document Goal This document provides the test results of a Base Station which provides mobile broadband connectivity using 700 MHz spectrum using the WiFi protocol. Flow Mobile had obtained a STA from the FCC to be able to test a Base Station in the 760-776 MHZ. The purpose of this test was to prove that WiFi protocol can be used at this spectrum and a mobile Base Station can be used to help deploy a large wide-area network. 2.0 Introduction A Base Transceiver Station (BTS) is a major component of any wireless access network to provide wireless service to users. A client terminal connects to a BTS to provide service to the user. Our demonstration is of a BTS operating in 760-776 MHz using WiFi protocol and the client used to test this BTS is based on an off-the-shelf module developed by Ubiquiti Networks. The client can be a handheld device, a computer card that is either connected using the PCMCIA slot or USB connector. The connection between the client and the BTS uses a particular protocol. The protocol could be any of CDMA, GSM, 3G standards or Wi-Fi standards or the future LTE standards. Hence a BTS has two components for the radio connection to be established between the BTS and the Client Terminal. The two components are frequency component which is purely a radio function and a protocol component which is a required for communication.

    Cellular Technologies Mobile Device Investigations Program Technical Operations Division - DFB DHS - FLETC Basic Network Design Frequency Reuse and Planning 1. Cellular Technology enables mobile communication because they use of a complex two-way radio system between the mobile unit and the wireless network. 2. It uses radio frequencies (radio channels) over and over again throughout a market with minimal interference, to serve a large number of simultaneous conversations. 3. This concept is the central tenet to cellular design and is called frequency reuse. Basic Network Design Frequency Reuse and Planning 1. Repeatedly reusing radio frequencies over a geographical area. 2. Most frequency reuse plans are produced in groups of seven cells. Basic Network Design Note: Common frequencies are never contiguous 7 7 The U.S. Border Patrol uses a similar scheme with Mobile Radio Frequencies along the Southern border. By alternating frequencies between sectors, all USBP offices can communicate on just two frequencies Basic Network Design Frequency Reuse and Planning 1. There are numerous seven cell frequency reuse groups in each cellular carriers Metropolitan Statistical Area (MSA) or Rural Service Areas (RSA). 2. Higher traffic cells will receive more radio channels according to customer usage or subscriber density. Basic Network Design Frequency Reuse and Planning A frequency reuse plan is defined as how radio frequency (RF) engineers subdivide and assign the FCC allocated radio spectrum throughout the carriers market. Basic Network Design How Frequency Reuse Systems Work In concept frequency reuse maximizes coverage area and simultaneous conversation handling Cellular communication is made possible by the transmission of RF. This is achieved by the use of a powerful antenna broadcasting the signals.

  • Components for 5G Base Stations and Antennas
    Quick guide COMPONENTS FOR 5G BASE STATIONS AND ANTENNAS www.essentracomponents.com MAKING IT EASIER QUICK GUIDE 5G TECHNOLOGY MANUFACTURERS FACE A CHALLENGE. With the demand for 5G coverage accelerating, it’s a race to build and deploy base-station components and antenna mast systems. Upgrading 4G base stations by software to non-standalone (NSA) 5G will still require hardware changes. It will act as an interim, but it will still not satisfy the need for true 5G network architecture. The number of base stations needed increases with each generation of mobile technology to support higher levels of data traffic. Antenna systems will also need to evolve to handle increases in capacity, frequency ranges and the ability to minimise interference as signal density expands. Your 5G base-station design and 5G antenna components will need to address not only technical challenges, but also aesthetics, weather and security requirements. This guide is designed to help you chose the components you’ll need. To further help you, we’ve made free CADs of our solutions available for download. You can also request free samples for most of our products, so you can try before you buy. ESSENTRACOMPONENTS.COM 2 QUICK GUIDE BASE STATIONS A 5G network base-station connects other wireless devices to a central hub. A look at 5G base-station architecture includes various equipment, such as a 5G base station power amplifier, which converts signals from RF antennas to BUU cabinets (baseband unit in wireless stations). Whatever you’re designing, you’ll need to consider cost, ease of installation and assembly and, of course, flammability.

  • Integration of Open-Source GSM Networks
    Integration of Open-Source GSM Networks Thomas A. Cooper Thesis submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Master of Science in Electrical Engineering Jeffrey H. Reed, Co-Chair T. Charles Clancy, Co-Chair Tamal Bose April 27, 2012 Blacksburg, Virginia Keywords: Open-Source Software, Network Architecture, Wireless, Software-Defined Radio, Cellular Network, GSM, Base Transceiver Station, Protocol Layers Copyright 2012, Thomas A. Cooper Integration of Open-Source GSM Networks Thomas A. Cooper ABSTRACT Global System for Mobile Communications (GSM) networks are receiving increasing attention in the open-source community. Open-source software allows for deployment of a mobile cellular network with lower costs, more customization, and scalable control. Two popular projects have emerged that offer varying network architectures and allow users to implement a GSM network in different capacities depending on individual needs. Osmocom provides more network control and scalability but requires commercial Base Transceiver Station (BTS) hardware with limited availability and closed source code. OpenBTS provides minimal GSM network functionality with more easily available and open-source hardware; however, it does not allow multi-cellular network configuration. This thesis offers a significant contribution towards a fully open-source GSM network by integrating the two major open-source communities, Osmocom and OpenBTS. Specifically, the Osmo-USRP program provides an inter-layer interface between the different network architectures of two GSM base station projects. Inter-layer primitive messages are processed in a thread multiplexer that manages logical channels across the interface. Downstream flow control is implemented in order to receive data frames on time for transmitting at the appropriate GSM frame number (FN).

  • On Mathematical Modelling of Automated Coverage Optimization in Wireless 5G and Beyond Deployments
    applied sciences Article On Mathematical Modelling of Automated Coverage Optimization in Wireless 5G and beyond Deployments Pavel Seda 1,* , Milos Seda 2 and Jiri Hosek 1 1 Department of Telecommunications, Brno University of Technology, Technicka 12, 616 00 Brno, Czech Republic; [email protected] 2 Institute of Automation and Computer Science, Brno University of Technology, Technicka 2, 616 69 Brno, Czech Republic; [email protected] * Correspondence: [email protected]; Received: 5 November 2020; Accepted: 7 December 2020; Published: 10 December 2020 Abstract: The need to optimize the deployment and maintenance costs for service delivery in wireless networks is an essential task for each service provider. The goal of this paper was to optimize the number of service centres (gNodeB) to cover selected customer locations based on the given requirements. This optimization need is especially emerging in emerging 5G and beyond cellular systems that are characterized by a large number of simultaneously connected devices, which is typically difficult to handle by the existing wireless systems. Currently, the network infrastructure planning tools used in the industry include Atoll Radio Planning Tool, RadioPlanner and others. These tools do not provide an automatic selection of a deployment position for specific gNodeB nodes in a given area with defined requirements. To design a network with those tools, a great deal of manual tasks that could be reduced by more sophisticated solutions are required. For that reason, our goal here and our main contribution of this paper were the development of new mathematical models that fit the currently emerging scenarios of wireless network deployment and maintenance.
