Further, the shared forward link channel, in addition to including a shared forward fundamental channel, may also include a shared forward supplemental channel.

In a virtual downstream channel environment, diverse downstream channel feeds are distinguished by authentication procedures.

The test channel and the reference channel have a merging region (7) downstream to said upper test channel section and a common downstream channel section (8).

In one embodiment of the system, each of the access channels is connected to a downstream channel, in which at least two of those downstream channels have a different bandwidth than the system bandwidth.

A heat exchanger (25) is interposed between the upstream tapping channel (22) and the downstream tapping channel (23).

The first pipe (14) is provided with two tappings (20, 21), including an upstream tapping (20) provided with an upstream tapping channel (22) and a downstream tapping (21) provided with a downstream tapping channel (23).

In such an embodiment, each of the downstream channels can receive the same data as its desired bandwidth.

The disk has a sidewall that abuts the upstream channel (11) and a bottom end that abuts the downstream channel (17).

This network communicates data from a base station to a mobile station over a supplemental forward channel.

In one embodiment of the invention, the apparatus has a hollow body having an upstream channel (11), a downstream channel (17), and a pressure reducing chamber between the upstream channel and the downstream channel.

A system and method for adaptive modulation of downstream communication between a wireless hub (180) and a wireless modem (120) on a selected downstream channel is provided.

A system and method for communication between a wireless modem (110, 112, or 114) and wireless hub (100) on a selected downstream channel of a plurality of downstream channels (120) is provided.

An expanded downstream channel (30) with multiple parallel capillary blood flow path provides continuing movement of blood past the filters (27).

The plurality of channels and the downstream channel occupy a bandwidth above about 50 MHZ, and (N/M)fs is below this bandwidth.

The invention adaptively increases or reduces the transmission power according to the case that the down channel transmission power is on the low side or on the high side.
