Node A will then begin transmitting while Node B knows to hold off transmitting it's data for the time being.

The radio interface between the UE and the Node B is called Uu.

Its power is usually between 5% and 15% of the total Node B transmit power.

Node B gets the packet and sends a packet back to Node A in acknowledgement.

The packet from Node B arrives at the switch.

A Node B can serve several cells, also called sectors, depending on the configuration and type of antenna.

Node B also has the incentive to bring A and C together to decrease the latent stress in two separate relationships.

A femtocell performs many of the function of a Node B, but is optimized for deployment in the home.

Because Node A is on a different segment than Node B, the switch must connect the two segments to send the packet.

In UMTS networks, if no Node B is accessible to a mobile, it will not be able to make any connections at all.
