5 Optimização de Redes Wireless = Engenharia + Know-how + T&M 2013 Wavecom wavecom

6 Optimização??? Auditoria, Consultoria e Gestão de Projetos de redes wireless Site-survey para redes wireless Concepção e Planeamento de redes wireless Instalação, Comissioning e Colocação em Serviço Optimização de redes wireless (já instaladas...) Capacidade de Teste e Medida, critério e experiência Engenharia Rádio Manutenção e Suporte

7 Capacidade de Teste e Medida Test & Measurement Power Frequency Phase Time Protocols Traffic Boundaries Propagation phenomena Interference Context Device (antenna, cable, amplifier, filter, splitter, coupler, etc) Equipment (AP, controller) Network Spectrum Analyzer Protocol Analyzer Anechoic Chamber Propagation Model Emulator MW and Radio Network Analyzer IxVeriWave

8 WaveTest: APs-Controller evaluation WaveDeploy: Deployed network acceptance Confirm performance Evaluate feature and functional performance Ensure repeatable test criteria Reduce test cycles Replicate real world client eco systems Evaluate and eliminate reported field issues

9 Simple, accurate benchmark testing Common configuration, reporting PDF report summarizing test results Design and Performance Testing Provides a WLAN parallel to RFC 2544 Benchmarking Throughput Packet loss Client capacity TCP Goodput R vs R Roaming Security Verify your performance

13 IxVeriWave WaveDeploy: Site assessment & acceptance tests

14 WF1101 Golden Client Traffic Generator/Analyzer WF1101 = network verification like never before Vs.

15 Testing and Reporting Reported metrics: Power RSSI Co-channel interference UDP downstream/upstream Max forwarding rate TCP downstream/upstream Max Goodput Voice MOS Video MDI Loss and jitter Client Roaming time (driver and OS dependent) Single Pass Site Survey - all measurements are conducted and recorded during a single pass HeatWave maps and individual measurements at every test stop available at the conclusion of site survey IxTest Wi-Fi Assessment

16 What s the signal strength? Is there co-channel interference? Is there connectivity? What voice quality can I expect to achieve? What video quality will I get? How will a device roam between APs? How many users can the network support? What QoE will I see when the network is loaded? How well do different devices work on the network IxTest Wi-Fi Assessment a a a a a a a a a IxTest Wi-Fi Assessment
