Broadband of cable television Cable receives DOCSIS2.0 technology to decode

Infrastructure exists already extensively, and have fiber-optic main force;

Have bigger than traditional line and wireless join bandwidth;

Need not dial, need not believe your agreement complexly;

Media is belonged to share a type, need not circuit exchange, fare is accordingly low, and endowment cost is not a foundation with join time, this accords with the spirit of Internet.

To newly-built intelligent village, aether net means is good choice for certain, not only cost is low, usable rate is high, more important is to accord with big technical strike, get used to net of prospective city land with certain boundaries to regard development direction of the foundation as aether net. But to particularly dispersive user, ADSL is only alternative. To Cable, the largest dominant position is cable television net gains ground quite, had had giant infrastructure, beardless and additional overmuch wiring project (but also need to undertake one-way change to be transformed two-wayly, increase Cable cat in head end namely terminative system) . Consequently to older village user and for more dispersive online crowd, cable is received is best choice. The reason on another technology is cable television cable is belonged to share line means, if user special concentration, the affiliation of each Cable user can increase noise, take up channel, reduce dependability and influence circuitry to go up already some users serve quality, cause the situation with not wide broadband finally. Net of commutative formula aether and ADSL won't produce this kind of situation.
