Feature Review

Asymmetric BW Allocation Enables 200 Mbps aggregate throughput per sector Increases range per given throughput Full scale Fixed UL/DL ratios: CBW Ratio 40 & 20 MHz 92% / 8% 10 MHz 83% / 17% 5 MHz 70% / 30% Attention: Same UL/DL ratio should be configured for all sectors in close proximity The configured UL/DL is applicable to all HSUs in the sector Online configuration - No service interruption 46

Spectrum Viewer: HBS & HSU Built-in spectrum analysis tool, enables selection of the best channel Enable to perform spectrum analysis outside of the operating band Enable define spectrum analysis from 1 min – 24 hours (resolution in seconds) Spectrum viewer operational modes: Per whole sector (HBS + HSUs) Per HSU – Directly or remotely via HBS Note: Service is affected during operation Max Interference report for all sector (DL) 47

Automatic Channel Selection (ACS) The HBS Sector Radio scans all available channels (user configurable) looking for the channel with less noise The channel with best performance will be assigned and inherited by registered HSUs Once a channel is being used, the radios monitor that the service is being provided at acceptable quality Consider relevant Consider as “Not relevant” Consider relevant Consider relevant CH1 CH2 CH3 … CH ‘N’ 48

Co – Location Interference When several HBS sector radios/PtP radios are collocated at a common hub site, interference may occur from one unit to another. f1 HBS HSUs Mutual interference f2 HBS HSUs 49

Hub Site Synchronization HSS Eliminates the Interference between the collocated units by synchronizing the TX and the RX of collocated radios HSS can also be connected to a GPS receiver (GSU) to allow synchronizing multiple sites f1 HBS HSUs HSS f2 HBS HSUs 50

Setting TX Ratio The HBS transmission ratio can be set to support symmetric (50/50) or asymmetric BW allocation The HBS TX ratio of the Downlink & Uplink is inherited by the sector HSUs When installing collocated HBS radios, all radios must utilize the same TX ratio The TX Ratio allocation is fixed (non-adaptive) 92% 8% 92% AU 92% UL/DL = 8/92 8% 8% 51
