1.3 Subscriber Unit
The Subscriber Unit (SU) installed at the customer premises enables the
customer data connection to the Access Unit. The Subscriber Unit provides an
efficient platform for high speed Internet and Intranet services. The use of packet
switching technology provides the user with a connection to the network that is
always on, enabling immediate access to services.
There are two types of Subscriber Units:
The SU-A/E series, where each unit comprises an Indoor Unit and an
Outdoor Unit (with or without an integrated antenna). These products are
intended for installation by a professional installer, enabling long-range
connectivity.
The SU-I series of all-indoor Subscriber Unit, intended for installation by non-
professional end users in locations that are close to the Base Station.
In addition, there is a special variant of a Subscriber Unit, the SU-E-BS, where
the indoor unit is designed for installation in the Base Station chassis. The
SU-E-BS is intended primarily for backhauling or similar applications.
The following sections provide additional details on the various types of
Subscriber Units.
