3.9 Wireless Network Deployment and Troubleshooting Ubee Interactive52 DDW3612 Subscriber User Guide • July, 20103.9 Wireless Network Deployment and TroubleshootingThis section provides the following information which may be useful in understanding,deploying, and troubleshooting wireless environments: “Wireless Speeds and Performance” on page 52 “Received Signal Strength” on page 52 “Estimating Wireless Cable Modem to Wireless Client Distances” on page 53 “Wireless Channel Selection” on page 553.9.1 Wireless Speeds and PerformanceThis section provides various topics on managing wireless speeds and performance: “Received Signal Strength” on page 52 “Estimating Wireless Cable Modem to Wireless Client Distances” on page 53 “Wireless Channel Selection” on page 553.9.1.1 Received Signal StrengthReceived signal strength (RSSI) is measured from connected wireless client devicesto the wireless cable modem. This value can significantly impact wirelessspeeds/performance. It is determined by: materials (e.g. open air, concrete, trees, etc.) distance between wireless clients and the wireless cable modem wireless capabilities of the client devicesTo determine the received signal strength, refer to “Wireless - Access Control” onpage 44 and review the RSSI value. A signal strength of -30dBm to -67dBm isconsidered optimal. Levels of -67dBm and lower (e.g. -70, -80, etc.) will have adownward impact on wireless data throughput.
