2 90% of homes in North America already have coax installed to at leastsome of the TV sets in the homeThe use of coaxial cable ensures a high level of shielding, providingimmunity to interference and noise (especially when compared to Wi-Fi) moca is compatible with cable modem networks as it occupies bandwidthabove the standard HFC frequency rangeMoCA provides the necessary throughput for transporting multiple datastreams carrying multimedia contentMoCA in the homeWi-Fi RepeaterMoCAclientSTBM odem / Router-or-MoCAAdaptor-or-MoCAEnabled DVRMoCAAdaptorMoCAAdaptor-or-MoCAenabled Modem/RouterMoCA capablesplitter or amplifierMoCA capablesplitter or amplifierSmart TVTVTVPCE thernetVideoCoax withRF & DataTapRFoGMoCA enabledIP ONTgroundblockWhole Home DVRWi-Fi RepeaterMoCAclientSTBM odem / RouterMoCAAdaptorMoCAEnabled

4 The Alliance publishes a list of certified products on their home moca supports two performance modes, Basic and Enhanced, with400 Mbit/s and 800 Mbit/s net throughputs (MAC), using 700 Mbit/s Gbit/s PHY rates, respectively. Turbo Mode yields 1 Gbit/s net throughput. Operating frequency range is 500 to 1675 MHz. Packet error rate is 1 packet error in 100 million. moca also offers lower power modes of sleep and standby and isbackward interoperable with moca TVHome NetworkHome Network + cable TVMoCA AttributesEight 50 MHz RF channels, 1125 to 1525 MHzEach channel has; 256 sub-bands, 224 occupied OFDM (orthogonalfrequency-division multiplexing)plus guard bands Each sub-band goes from BPSK (binary phase-shiftkeying)to 256 QAM in near real time Channel 1 (1125-1175) is most likely choice, can be madea requirement via addressable set top controlsMoCA AttributesSystem operation 175 Mbps throughput (target PHY rate of 270 Mbps) Demonstrated operation to 57 dB dynamic range Transmitter lowers power when link exceeds target rate Beacon always at maximum output power (56 dBmV)

Some MSOs are considering lowering the beacon to 40dBmV, which also reduces the link budget to 41 dB, due toconcerns with overdriving the input to non- moca enableddevices with the high beacon carrier level Up to 16 devices on the in-home networkMoCA ChangesBaseline Mode400+ Mbps MAC throughput (500+ Mbps in turbo mode)700 Mbps PHY rateSingle 100 MHz channelEnhancedMode800+ Mbps MAC throughput (1+ Gbps in turbo mode) Gbps PHY rateDual bonded 100 MHz channels (channel bonding)ExpandedOperatingFrequencyRange5 00 through 1675 MHzAdditionalChangesEnergy saving modesReliability improvements (latency, improved Packet Error Rate, re-transmission)Backward Interoperability with moca Operating Characteristics5-42 Upstream54 860 MHz (up to 1 GHz)
