RoHS and WEEE Compliance
The Aprisa SR+ is fully compliant with the European Commission’s RoHS (Restriction of Certain Hazardous Substances in Electrical and Electronic Equipment) and WEEE (Waste Electrical and Electronic Equipment) environmental directives.
Restriction of hazardous substances (RoHS)
The RoHS Directive prohibits the sale in the European Union of electronic equipment containing these hazardous substances: lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs).
4RF has worked with its component suppliers to ensure compliance with the RoHS Directive which came into effect on the 1st July 2006.
End-of-life recycling programme (WEEE)
The WEEE Directive concerns the recovery, reuse, and recycling of electronic and electrical equipment. Under the Directive, used equipment must be marked, collected separately, and disposed of properly.
4RF has instigated a programme to manage the reuse, recycling, and recovery of waste in an environmentally safe manner using processes that comply with the WEEE Directive (EU Waste Electrical and Electronic Equipment 2002/96/EC).
4RF invites questions from customers and partners on its environmental programmes and compliance with the European Commission’s Directives (sales@4RF.com).

Compliance General
The Aprisa SR+ radio predominantly operates within frequency bands that require a site license be issued by the radio regulatory authority with jurisdiction over the territory in which the equipment is being operated.
It is the responsibility of the user, before operating the equipment, to ensure that where required the appropriate license has been granted and all conditions attendant to that license have been met.
Changes or modifications not approved by the party responsible for compliance could void the user’s authority to operate the equipment.
Equipment authorizations sought by 4RF are based on the Aprisa SR+ radio equipment being installed at a fixed restricted access location and operated in point-to-multipoint or point-to-point mode within the environmental profile defined by EN 300 019, Class 3.4. Operation outside these criteria may invalidate the authorizations and / or license conditions.
The term ‘Radio’ with reference to the Aprisa SR+ User Manual, is a generic term for one end station of a point-to-multipoint Aprisa SR+ network and does not confer any rights to connect to any public network or to operate the equipment within any territory.
Compliance European Telecommunications Standards Institute

3.About the Radio
The 4RF Aprisa SR+ Radio
The 4RF Aprisa SR+ is a Point-To-Multipoint (PMP) and Point-To-Point (PTP) digital radio providing secure narrowband wireless data connectivity for SCADA, infrastructure and telemetry applications.
The radios carry a combination of serial data and Ethernet data between the base station, repeater stations and remote stations.
A single Aprisa SR+ is configurable as a:
Point-To-Multipoint base station, remote station, repeater station or a base-repeater station
Point-To-Point local or remote radio
Aprisa SR+ User Manual 1.6.0 PO
18 | About the Radio
Product Overview
Network Coverage and Capacity
The Aprisa SR+ has a typical link range of up to 120 km, however, geographic features, such as hills, mountains, trees and foliage, or other path obstructions, such as buildings, will limit radio coverage. Additionally, geography may reduce network capacity at the edge of the network where errors may occur and require retransmission. However, the Aprisa SR+ uses 10W output power and Forward Error Correction (FEC) which greatly improves the sensitivity and system gain performance of the radio resulting in less retries and minimal reduction in capacity.
Ultimately, the overall performance of any specific network will be defined by a range of factors including the RF output power, the modulation used and its related receiver sensitivity, the geographic location, the number of remote stations in the base station coverage area and the traffic profile across the network. Effective network design will distribute the total number of remote stations across the available base stations to ensure optimal geographic coverage and network capacity.
One base station can register and operate with up to 500 remote / repeater stations.
The practical limit of remote / repeater stations that can operate with one base station is determined by a range of factors including the number of services, the packet sizes, the protocols used, the message types and network timeouts.
Automatic Registration
On start-up, the remote station transmits a registration message to the base station which responds with a registration response. This allows the base station to record the details of all the remote stations active in the network.
If a remote station cannot register with the base station after multiple attempts within 10 minutes, it will automatically reboot. If remote is not able to register with base station in 5 attempts, then a ‘Network Configuration Warning’ alarm event will be raised indicating that a remote is not registered with the base station.
If a remote station has registered with the base station but then loses communication, it will automatically reboot within 2 minutes.
Remote Messaging
There are two message types in the Aprisa SR+ network, broadcast messages and unicast messages. Broadcast messages are transmitted by the base station to the remote stations and unicast messages are transmitted by the remote station to the base station. These messages are commonly referred to as uplink (unicast remote to base) and downlink (broadcast base to remote).
All remotes within the coverage area will receive broadcast messages and pass them on to either the Ethernet or serial interface. The RTU determines if the message is intended for it and will accept it or discard it.

Store and Forward Repeater
The Aprisa SR+ in Repeater mode is used to link remote stations to the base station when direct communication is not possible due to terrain, distance, fade margin or other obstructions in the network. The following example depicts a repeater on the hill top to allow communication between the base station and the remote stations on the other side of hilly terrain.
Repeater Packet Forwarding
The Aprisa SR+ works in packet Store and Forward (S&F) for simple and low cost repeater network.
Repeater mode is available in both Access Request (AR) and Listen Before Send (LBS/CSMA) MAC operating modes. It allows a radio in Repeater mode to store a received packet and retransmit it.
Single Repeater Single Hop
The following example depicts an Aprisa SR+ single repeater single hop Store and Forward network.
Aprisa SR+ User Manual 1.6.0 PO
20 | About the Radio
Multiple Repeater Single Hop
The following example depicts an Aprisa SR+ multiple repeater single hop store and forward network supporting both overlapping and non-overlapping coverage repeater networks. An overlapped RF coverage area creates radio interference and might affect network performance and reduce throughput, as show in figure (a), where Remote 1 is in overlapped RF coverage with Repeater 1 and Repeater 2.
The Aprisa SR+ functionality allows repeaters in Bridge mode to forward Ethernet packets based on Repeater Network Segment ID. The base station translates the destination address (DA) to the Repeater Network Segment ID. This improves repeater performance by forwarding the packet if the Repeater Network Segment ID belongs to the repeater branch and discards the packet if it doesn’t.
Router mode supports repeater packet forwarding based on IP destination address. This improves repeater performance by forwarding the packet if the IP destination address belongs to the repeater branch and discards the packet if it doesn’t

About the Radio | 21
Multiple Repeater Multiple Hop
The following example depicts an Aprisa SR+ daisy chain multiple repeater multiple hop store and forward network i.e. multiple hops and multiple repeaters in non-overlapping RF coverage. The Aprisa SR+ daisy chain store and forward repeaters are currently supported in LBS MAC mode only.
In any type of store and forward repeater network base, repeater and remote radios must have their Tx/Rx frequencies sets to match to their appropriate linking devices as shown in the figures.
Note: Frequencies shown in the figures relates to the device on the left where {Tx, Rx} = {fx, fy}. In this example, the Base Station, Repeater 2 and remotes are deployed with Tx=f1 and Rx=f2. On the other hand Repeater 1 and Repeater 3 are deployed with Tx=f2 and Rx=f1, creating the required linking for daisy chain operation.
Aprisa SR+ User Manual 1.6.0 PO
22 | About the Radio
Repeater Messaging
The Aprisa SR+ uses a routed protocol throughout the network whereby messages contain source and destination addresses. The remote and repeater stations will register with a base station. In networks with a repeater, the repeater must register with the base station before the remotes can register with the base station.
Additionally, based on destination address, messages are designated as either a ‘broadcast’ message, (mostly originating from a base station) or a ‘unicast’ message (mostly originating from a remote station).
In a network with a repeater, or multiple repeaters, the base station broadcasts a message which contains a source address and a destination address. The repeater receives the message and recognizes it as a broadcast message, from the destination address and re-broadcasts the message across the network. In IP routing mode all remote stations in the coverage area will receive the message but only the radio with the destination address will act upon the message.
Similarly, the remote station will send a unicast message which contains a unicast destination address (the base station). The repeater will receive this message; recognize the destination address and forward it to the appropriate destination address.
In order to prevent repeater-repeater loops, a detection mechanism of ‘duplicate message’ and use of unicast messaging in remote to base/repeater direction is used.
For example, in the Multiple Repeater Single Hop figure above, the topology is of Base, Repeater 1, Repeater 2 and Remote 1 connected to Repeater 1 in overlapping coverage, where Remote 1 can also hear Repeater 2. When the Base station broadcasts a message, Remote1 will receive this message from both Repeater 1 and Repeater 2 but will drop one of them as ‘duplicate message’. It is possible that Repeater 1, for example, can also hear the broadcast sent out by Repeater 2. In this case, Repeater 1 will drop this broadcast as a ‘duplicate message’.
These phenomena will not happen in the upstream direction as all messages are sent ‘unicast’. Remote 1 will send a packet to Base station, setting the destination address in packet to Base station and ‘next hop’ address in packet to Repeater 1. Thus, only Repeater 1 will forward the packet to Base station and
Repeater 2 will drop the packet as the ‘next hop’ address is not Repeater 2.

Peer To Peer Communication Between Remote Radios
The Aprisa SR+ peer to peer communication between remote radios is used to enable communication between remote radios via the repeater or base-repeater. It is useful if the SCADA server or base station fails or when in some industries like the water industry, where a reservoir remote station might send a direct message to a valve remote station to close or open the valve without the intervention of the SCADA server.
The Aprisa SR+ has a special operating mode for peer to peer communication between remote radios and requires the following settings:
1.If peer to peer communication between remote radios is required to operate via the base station, then the SuperVisor > Terminal > Operating Mode > Terminal operating mode must be set to ‘BaseRepeater’. Base-Repeater operating mode doesn’t change the Network Radius parameter as the base-repeater is considered to be like a regular base station.
2.The remote radios participating in peer to peer communication must set the SuperVisor > Radio > Channel Setup > Packet Filtering to Disable to allow a repeated packet received from peer to peer remote radios by the repeater or base-repeater to forward the packet to the relevant interface and not to discard it.
3.IP Header Compression must be disabled on all radios (base, repeater, remotes) for this feature to operate correctly (See ‘IP Header Compression Ratio’ on page 119).
4.The Network Repeaters Proximity must be set to ‘Base Repeater’ on all remote radios for this feature to operate correctly (See ‘Network Repeaters Proximity’ on page 89’).
5.Note: In ‘Router Mode’ setup a static route for any required peer to peer path.
The following example depicts peer to peer communication between remote radios via a base-repeater and via a repeater station where remote-1 and remote-2 communicate with each other via the baserepeater station and remote-3 and remote-4 communicate with each other via the repeater station. All the remote radios are configured with packet filtering disabled and all radios in the network are configured with IP header compression ratio disabled.
Note: The Aprisa SR+ network is transparent to the protocol being transmitted; therefore the Packet Filtering parameter is based on the Aprisa SR+ addressing and network protocols, not the user (SCADA, etc.) traffic protocols.

System Gain vs FEC Coding
This table shows the relationship between modulation, FEC coding, system gain, capacity and coverage.
Maximum FEC coding results in the highest system gain, the best coverage but the least capacity
Minimum FEC coding results in lower system gain, lower coverage but higher capacity
No FEC coding results in the lowest system gain, the lowest coverage but the highest capacity
This table defines the modulation order based on gross capacity:

Architecture
The Aprisa SR+ Architecture is based around a layered TCP/IP protocol stack:
Physical Proprietary wireless
RS-232 and Ethernet interfaces
Link
Proprietary wireless (channel access, ARQ, segmentation) VLAN aware Ethernet bridge
Network Standard IP
Proprietary automatic radio routing table population algorithm
Transport TCP, UDP
Application
HTTPS web management access through base station with proprietary management application software including management of remote stations over the radio link
SNMPv1/2/3 for network management application software
Product Operation
There are three components to the wireless interface: the Physical Layer (PHY), the Data Link Layer (DLL) and the Network Layer. These three layers are required to transport data across the wireless channel in the Point-to-Multipoint (PMP) configuration. The Aprisa SR+ DLL is largely based on the 802.15.4 Media Access Control (MAC) layer using a proprietary implementation.
Physical Layer
The Aprisa SR+ PHY uses a one or two frequency half duplex transmission mode which eliminates the need for a duplexer. However, a Dual Antenna port option is available for separate transmit and receive antenna connection to support external duplexers or filters (half duplex operation).
Remote nodes are predominantly in receive mode with only sporadic bursts of transmit data. This reduces power consumption.
The Aprisa SR+ is a packet based radio. Data is sent over the wireless channel in discrete packets / frames, separated in time. The PHY demodulates data within these packets with coherent detection.
The Aprisa SR+ PHY provides carrier, symbol and frame synchronization predominantly through the use of preambles. This preamble prefixes all packets sent over the wireless channel which enables fast Synchronization.
