1. Product
RAy3 microwave units work as a wireless Ethernet point-to-point link in a full duplex setting with
transfer speeds of up to 1010 Mbps. The link is formed by two RAy units, each equipped by its own
parabolic antenna and accessories to be fully operational.

1.1. Main characteristics

Supported are several license-free bands and several licensed bands, all in the identical aluminum
box. Bandwidth can be configured from 3.5 up to 112 MHz for standard bands (all models up to 42
GHz) and from 62.5 up to 2000 MHz for E-band (71-86 GHz). Modulation can be fixed or adaptive and
for standard bands it can be adjusted from QPSK to 4096QAM. In the case of E-band modulations
range from 2PSK up to 128QAM. The lowest modulation on each model could be on the fly (without
data loss) strengthened for higher receiver sensitivity by extremely robust FEC – such modulation is
marked as QPSK_S or 2PSK_BW/4_S (where 'S' means a strong FEC and 'BW/4' means a narrower
channel used in E-band only). RAy3 microwave links operating in 17 and 24 GHz bands can also be
operated as a Short Range Device (SRD).

1.1.1. Hardware concept
RAy product line has been designed to have minimum possible number of hardware variants. Function-
ality of the unit is upgraded according to the "pay-as-you-grow" concept only by activating the relevant
software feature keys and does not require any on-site hardware changes. For details see Section 1.7,
"Ordering codes" and Section 5.6.1.2, "SW feature keys".
HW models are determined only by frequency bands and in the case of licensed bands (i.e. 10, 11 and
18 GHz) also by sub-bands. Additionally in 10, 11, 18 and 80 GHz bands units forming a link differs in
HW duplexer which ensures the proper frequency separation of transmitting and receiving channels.
This is marked on each unit as Lower (L) or Upper (U) in Production code according the position of
transmitting channel.
