Indoor-Mounted Radio Hardware and Cable Overview

Indoor Radio Hardware

Model 5054, 5012-SUI, and 5054-SUI radios are intended for indoor mounting and operation. For these indoor radios, the

antenna cable is connected to the connector pigtail extending from the radio.

The following types of radio devices are used for setting up a wireless link with the 5054, 5012-SUI, and 5054-SUI:

• Tsunami MP.11 5054 (MP.11a) Base Station Unit (BSU)

• Tsunami MP.11 5054 (MP.11a) Subscriber Unit (SU)

• Tsunami MP.11 5054 (MP.11a) Residential Subscriber Unit (RSU)

• Tsunami MP.11 5012-SUI Subscriber Unit (SU)

• Tsunami MP.11 5054-SUI Subscriber Unit (SU)

Indoor Radio Cable Setup for an External Antenna

The following items are required on each end of the wireless link:

• A Base Station on one end and a Subscriber Unit on the other end.

• A surge arrestor to protect your sensitive equipment from static discharge and transients (optional, but highly

recommended).

• N-type female-female converter connector (optional, needed only if a surge arrestor is not used, or if an additional

antenna cable is required when a surge arrestor is used, see next bullet).

• A low-loss antenna cable to connect the indoor radio unit to the surge arrestor (optional, only if the radio unit is not

mounted close to where the cable coming from the antenna enters the building, which is the place where the surge

arrestor must be mounted).

• A low-loss antenna cable to connect the surge arrestor to the outdoor antenna (if surge arrestor is used), or the unit to

the antenna (if surge arrestor is not used).

• External antennas (one at each end).

• A grounding system, as described in Grounding the Antenna.

When the unit is not mounted close to where the antenna cable enters the building (where the surge arrestor must be

mounted), an additional cable between the unit and the surge arrestor is required, plus a female-female converter

connector. If the unit is mounted close to the surge arrestor, the unit can be connected directly to the surge arrestor.

Proxim strongly recommends to use a surge arrestor to protect your sensitive equipment from static discharge and

transients. An exception to this rule is when the antenna is installed in an indoor location. This installation does not

require the use of a surge arrestor. The antenna can be connected directly to the radio unit via a cable and a

female-female converter connector.

All cabling components of the antenna system come with standard-N type connectors. Note that the gender of the

connector is not determined by the connector’s thread, but by its center pin. A solid center pin = male; a hollow center pin

= female.

The following sections describe all the possible combinations of cabling components. The 5012-SUI/5054-SUI is

pictured.

• Indoor Radio Cable Setup with a Surge Arrestor Close to the Unit

• Indoor Radio Cable Setup with a Surge Arrestor Not Close to the Unit
