>30 dB downstream

>20 dB Upstream

Downstream Channel Size

6 or 8 MHz, can be bonded into two eight channel groups

Downstream Modulation


Max Total Data Downstream (Mbps)

>216 Mbps for NA DOCSIS 3.0 per 8 channel group

Upstream Channel Size

Four simultaneous upstream channels each of the channels can be 3.2 MHz, 1.6 MHz, or 800KHz in size

Upstream Modulation

QPSK/8QAM/16QAM selectable

Max Total Data rate Upstream (Mbps)

> 32 Mbps for NA DOCSIS 3.0

Degradation over distance

High output power is used to have the same downstream data rate for all subscribers over the coverage area.
For upstream DOCSIS provides power adaptation and Ai uses bandwidth adaptation to reduce effect of distance.

Full Duplex Operation?

Yes, Frequency Division Duplexing (FDD)

Licensed Channels Required

Yes, two for each FDD pair, each 6 MHz, at least 24 MHz apart
Single channel carries up to 24 SDTV or up to 8HDTV signals downstream multicasting

Frequency of Operation

470 – 860 MHz UHF band downstream
5 – 85 MHz upstream up converted to 470-860 MHz

Fixed Operation from tower to CPE

Yes, within service area

Nomadic Operation

Yes, between tower and moveable unit in service area
