Control Unit (PCU) in the Base Station System (BSS).

2.1.1 Internet Service Provider (ISP) Customer-Premise Domain
The Customer-Premise Domain consists of small form factor PicoBTSs with DSL and/or
cable modem/router connections to the Backhaul Domain. Each PicoBTS is connected to
the DSL/cable modem/router via an RJ-45 CAT5 Ethernet cable.
• Connection to the Backhaul Domain may alternatively be provided through a
customer-premise LAN
• PicoBTSs are distributed in the customer premises to optimize coverage
• Each PicoBTS acts as a single picocell
2.1.2 Backhaul Domain
The Backhaul Domain provides secure transport between the PicoBTSs and the S-AGW
in the Infrastructure Domain. The Backhaul IP Domain must also include a local DHCP
server or access to a DNS server.
The backhaul domain link must meet minimum performance requirements.
2.1.3 Carrier Infrastructure Domain
The Infrastructure Domain consists of a mobility network and optionally a separate data
network that provides access to the Internet. Common to both networks is a firewall
(optional).
The S-AGW manages system resources and multiplexes/de-multiplexes user traffic to
multiple RadioFrame customer-premise PicoBTSs. Each PicoBTS is configured to be a
logical 1-TRX Metro-Site BTS from the BSC’s point of view.
Note: The Transcoder Rate Adaptation Unit (TRAU) function is required, as it is for an
existing GSM BTS.
