The RAy microwave links are designed for data transmissions in both licensed and unlicensed ISM bands. They work as a point-to-point link in full duplex regime with transfer speed up to 360 Mbps. Bandwidth is selectable from 1.75 up to 56 MHz. Modulation can be fixed or adaptive and can be adjusted from QPSK to 256QAM.
The link is formed by two FOD (Full Outdoor) stations. In the case of links operating in the ISM bands (RAy17, RAy24), both stations have identical hardware. In the case of links operating in the licensed bands, one unit is transmitting in the Lower and receiving in the Upper part of the band. The other unit is operating vice versa.
RAy links are used with external parabolic antennas. Parabolic antennas from different producers are available.
Cross polarization – valid only for links operating in the ISM bands (RAy17, RAy24):
One side of the link uses one polarization for transmission (e.g. horizontal) and the opposite polarity for receiving (e.g. vertical). The other side of the link is turned by 90°. It therefore transmits and receives using opposite polarizations with respect to the other side.

Every model can be supplied in two different versions:
with one metal Ethernet port, e.g. RAy17
with two metal Ethernet ports, e.g. RAy17-2
For details see Section 3.6, “Ordering codes”
A detailed table of frequencies can be found in Chapter 9, Technical parameters.
The antenna is attached to the mast using a holder adjustable in two planes. The RAy unit is then mounted on the antenna. There are two possible mounting positions – for horizontal and vertical polarization. Installation and adjustment of the holder is described in Chapter Antenna mounting.
LAN connection is possible using one or two connectors:
The RAyXX version uses a single connector for user data, service access and PoE
The RAyXX-2 version uses two connectors, one for user data and PoE power supply and one for service access. For assembly of connectors see chapter Connectors.
The third BNC connector serves for connecting voltmeter for RSS indication during the antenna adjustment process.

Andrew (Class 2 or 3) or Arkivator antennas are also possible to be used with antenna mounting kit. Flexible waveguide is a general-purpose option for any antenna usage.
Name plate
The plate contains name, bar code record, CE label, etc.:
Type – RAy product line identification
Code – detailed identification of the station type (see annex for details Section 3.6, “Ordering codes”)
S/N – serial number, link contains stations with two different numbers
MAC – HW address of user ethernet port
The proper pair of Lower and Upper units should be selected when ordering the microwave link. This is not true for ISM bands units (RAy17, RAy24). In such a case the same unit is used for both sides of the link.
Note – The Lower and Upper unit has to be selected from the same sub-band (i.e. from the same row of the table).
The RAy10 ordering codes are stated here for clarity. The RAy10 User manual can be found here.
In case of the two-port units, the “-2” label shall be connected to the end of the ordering code. Example:
RAy11-LA-2
RAy17-2
The Feature keys ordering code consists of three parts:
XXX-YYY-ZZZ
XXX
– Product type, e.g. “RAy11”.
YYY
– Feature key type.
The
“SW” key is available now. This key unlocks the User speed to given
value.
ZZZ – Feature
key value. In case of User speed it states Mbps. Example:
RAy11-SW-100 … RAy11 user data speed max. 100 Mbps.
RAy17-SW-360 … RAy17 user data speed max. 360 Mbps.
The microwave bridge comes supplied as standard with:
two FOD units
two antenna dishes with brackets for mounting on a mast – based on the user requirements and specifications
tub of NOVATO silicon lubricant (mixture of silicon grease, PTFE and other additives) for lubricating the antenna pin. (see Section 5.2.3, “Lubrication and preservation of the antenna pivot”)
Microwave bridge accessories need to be ordered separately, for further details please see www.racom.eu
