1INTRODUCTION
1.1 MDR5800 Description
The MDR5800 is a 5.8 GHz digital radio system that provides short to medium range,
point-to-point digital communication with high data security at rates of E1, 2E1 or 4E1.
Alternatively, the radio can be software configured to convey T1, 2T1 or 4T1. The
radio can also be configured to bridge or route IP via a 10BaseT Ethernet port. The
data rates scale depending on the number of enabled E1/T1 tributaries and whether
the data is being bridged or routed. The product makes use of spread spectrum
technology and may be operated license-free in the 5.8 GHz ISM band. It is ideal for
applications such as:
•Telecommunications companies, cellular operators and private carriers.
•Cellular/PCS base station interconnects.
•Internet distribution.
•Video surveillance data distribution.
•Rural communications.
The MDR5800 consists of two main parts:
•An Outdoor Unit operating in the 5.8 GHz ISM frequency band.
•An Indoor Unit, available with a Telecommunications (1, 2 or 4E1 or 1, 2 or
4T1) interface and a Data interface (10BaseT Ethernet).
Interconnection between the Outdoor Unit and Indoor Unit is achieved using a low-
cost UV-protected STP (Screened Twisted Pair: 4 pairs) data cable and a UV-
protected 2-core power cable. The MDR5800 series product uses a split Indoor Unit
and Outdoor Unit configuration for lowest loss between the antenna and the
transceiver, thereby ensuring optimal long-range performance.
MDR5800 Outdoor Unit uses a Type-N RF (female) output connector for connection
to any 5.8 GHz antenna for applications where long range is required.
The system is available for use in FCC regulated countries.
