Como compilamos isto
Covers standalone DOCSIS cable modems: retail modems a subscriber buys to replace an ISP-rented unit on a cable (HFC) broadband line, sold at a published US price. Includes modem-only units and modems with built-in Ethernet; excludes modem/router (gateway) combos, cable-line MoCA adapters, and fiber (GPON/XGS-PON) or DSL modems. Price is typical US MSRP or street price, USD, for the modem-only SKU. docsisVersion is the DOCSIS specification the modem supports as a string ('3.0', '3.1', or '4.0'). maxDownloadGbps is the manufacturer's rated maximum downstream throughput in gigabits per second. maxUploadGbps is the rated maximum upstream throughput in Gbps. channelBonding is the bonded SC-QAM channel count as a 'downstream x upstream' string (e.g. '32x8'). ofdmChannels is the OFDM/OFDMA channel count as a 'downstream x upstream' string (e.g. '2x2'). ethernetPorts is the number of RJ-45 LAN ports. maxEthernetSpeedGbps is the fastest single Ethernet port's rated speed in Gbps (e.g. 1, 2.5, 10). linkAggregation is a boolean for teaming two Ethernet ports for higher combined throughput. midSplitSupport is a boolean for DOCSIS mid-split (expanded upstream) capability. activeQueueManagement is a boolean for DOCSIS-AQM / low-latency (bufferbloat) support. weightGrams is the unit weight in grams. Any spec not stated verbatim on a fetched manufacturer or retailer page is left null.
