4 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 4 (41) 1 Introduction 1.1 General The Swedish Defence Materiel Administration (FMV) is seeking a supplier (i.e. one supplier) that can provide a (one) complete tactical ground radio system (TGR) to support communications within a battalion. The TGR system shall provide the following services: Seamless wireless IP communication to mobile nodes within a battalion and with the existing Swedish deployable and fixed IP network. High data rate capacity to support Battlefield Management System (BMS) data service. Multiple voice sessions (based on VoIP traffic). The present approach is that the TGR consist of two waveforms: A wideband waveform that supports BMS data services and voice sessions over multiple RF hops. A narrowband waveform offering extended range that supports voice services including a low rate data service.

5 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 5 (41) Figure 1. TGR waveforms and services. The system shall enable wireless communication between soldiers, soldiers to vehicles and between vehicles in a seamless operation as shown in Figure 1. Main operation is ground to ground communication but ground - to - helicopter operation as well as capabilities to handle tactical satellite and Forward Air Controller (FAC) communications are also of interest. The hardware components of the TGR system shall support the following use cases as indicated in Figure 2: Case I - handheld operation. Case II - manpack operation Case III - fixed vehicular mounted operation.

6 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 6 (41) Figure 2. TGR use cases. Use case I shall support handheld operation. At least one waveform shall be possible to use at a time. Use case II shall support manpack operation. The radio hardware component supporting use case II should be possible to be used in a vehicle using a vehicle adapter. It is preferred that two waveforms can be used simultaneously. One may consider a two waveform solution (with potential cross-banding functionality) based on a two radio hardware component configuration set (each set supports only one waveform at a time), depending on the physical form factor. Use case III shall support fixed vehicle mounted operation. Two waveforms shall be possible to use simultaneously. It should be possible to use three waveforms simultaneously. Note that it is expected that hardware components supporting use case II shall have the ability to be mounted in a vehicle. It is up to the Supplier to suggest suitable radio hardware components that will support the defined use cases. 1.2 Delivery content The delivery content of the TGR system comprises: TGR hardware components (including antennas, filter etc) needed to support the defined use cases.

7 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 7 (41) TGR waveforms as well as standardized waveforms. Management tools/solution. Training and documentation. Technical support (consultation, logistic support management, obsolescence management, administration of HW and SW etc). The content will depend on the chosen method to handle the Life Cycle of the system. Porting Different alternatives are considered regarding acquisition and Life Cycle handling. This is further described in section 5. The waveforms and radio types may be produced by different manufacturers but the Supplier must take responsibility to deliver the total system solution to FMV. The TGR system shall be based on suitable Non Development Items (NDI) waveforms and products. Note: NDI is defined as a product/item without any explicit development cost such as for example Non-Recurrent Costs (NRC). As the TGR system is rolled out new demands may arise which may require upgrades of the TGR system. Such upgrades could be a mix of the Suppliers own SDR roadmap (without customer funded NRC) as well as require customer funding. This is further discussed in section Delivery schedule FMV is seeking a Supplier willing to take a long term responsibility of the TGR system. Present plans include activities at least to A tentative time schedule is shown in Figure 3

8 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 8 (41) Figure 3. Tentative time schedule. Note that the Personal Role Radio (PRR) system is currently acquired separately from the TGR system but could be considered as an option in a future RFQ. The procurement is divided in two phases. Phase two will be handled as options in the contract on phase one. Additional phases after 2022 are possible. First delivery of phase one shall start not later than Q1 in It shall primarily support use case II but about 10 % of the hardware components shall support use case III. First delivery shall comprise of units. Final delivery of phase one shall be completed not later than Q Total number of units in phase one is estimated to 300 units supporting use case I, 1500 units for use case II and 400 supporting use case III. Approximately 75 % of the hardware components supporting use case II shall be vehicle mounted. Phase two will comprise of similar number of units (as seen in Figure 3) and need to be delivered within the time frame In order to facilitate a short time to first delivery the contractor may first deliver some basic functionality to be upgraded to full functionality later during phase one. Note that this refers to software upgrade, the hardware must be final. The procurement of the TGR system will be made in competition according to the Swedish Public Procurement Act (2007:1091).

12 Data (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 12 (41) 2 System Description This RFI addresses a radio system intended for the Swedish Armed Forces. The radio system will be used to transfer digitized voice and data information. All user data information (including voice) to be transferred by the radio system shall primarily be based on IP. The TGR shall primarily support communications within a battalion. 2.1 System in focus The main content of the system in focus as well as the external systems that will be connected to the radio system are shown in Figure 4. Voice Data Voice Voice Voice Voice Figure 4. System in focus. The TGR system consists of different hardware components to support use cases I - III and waveforms (including antennas and cosite filter if needed). A vehicle adapter may be used to support vehicle mounting of hardware components supporting use case II. The system also includes management and configuration software, either embedded in the radio or external to the radio.

13 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 13 (41) This software shall be possible to access or run using an external (management) PC. The key fill device, to handle TRANSEC keys, may be part of the TGR system. It may also be supplied as GFE. The keys will be generated using an existing local key generation system (LNP). Power supply is external to the system and will differ depending on radio hardware component. Batteries needed for dismounted radios shall be included in the system. The TGR system will be connected to the Soldier Node system. The Soldier Node system is a development project, and an RFQ is scheduled to be released in 2013 with first prototypes available in The requirements for TGR and the Soldier Node are written in co-operation between these two projects. The Soldier Node is a personal wearable encryption/decryption device expected to offer secure voice and encrypted data functionality. It shall be possible to connect the Soldier Node directly to the TGR system. MELPe (2400 bit/s) voice encoding will be available in the Soldier Node. The Soldier Node will have the ability to aggregate a configurable number of voice frames into a single IP packet. When the TGR system is used inside a vehicle it is connected to the KomNod system. The KomNod system handles routing of BMS data traffic as well as voice, both internal and external to the vehicle. The BMS data is generated and encrypted within the vehicle. The Soldier Node is used within the vehicle to enable secure voice. In this case the Soldier Node is connected to the KomNod system and NOT to the TGR system. The TGR system may also need to transfer other IP based traffic such as routing traffic, NTP etc. An important system design rule is that COMSEC handling is done externally to the TGR system as shown in Figure 4. This applies to all IP traffic, both VoIP and BMS data, which will be transferred using the TGR system. The Figure 5 shows possible installation of different radio hardware components supporting use case II - III within a vehicle.

14 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 14 (41) Figure 5. Possible installation of the TGR system in a vehicle. The abbreviation II (V) correspond to vehicle mounted hardware components supporting use case II. Depending on vehicle type there may be different combinations of radio hardware components installed. One should also note the possibility that the Ra 460 radio (see below) as well as other legacy radio systems may be installed together with the TGR system depending on vehicle type. It shall be possible to install (in a vehicle/platform) any radio hardware component (including power amplifiers) supporting use case II III within the following space: Depth 370 mm, Width 406 mm and Height 227 mm. There may be scenarios when the Soldier Node is not available. The TGR system, at least hardware components supporting use case I and II, should be able to handle un-secure voice traffic using a headset or a handset directly connected to the radio. The Swedish Armed Forces are currently fielding a vehicle-based, battalionlevel radio system named Ra 460. It is based on the Rockwell Collins FlexNet-4 hardware platform and the FN-4 waveforms. The waveforms consist of one wideband and one narrowband waveform, both supporting ad hoc relaying. The

15 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 15 (41) main purpose of the FN-4 waveforms is to enable a seamless wireless IP network that supports BMS data services. The FN-4 waveforms are not optimized for VoIP communications. The FN-4 platform has an embedded Cryptographic Sub System that supports TRANSEC functionality. The platform has also a black Ethernet interface enabling usage of external COMSEC devices. The waveforms are compliant with the Software Communications Architecture (SCA) standard. It shall be possible to operate the TGR system without access to GPS timing. If GPS or NTP timing is available the system may use it to enhance performance. It shall be possible to set a radio in radio silence. It shall be possible to receive data (including voice) while in radio silence. 2.2 Future development of the TGR system As the TGR system is rolled out new demands may arise which may require upgrades of the TGR system. Such upgrades could be a mix of the Suppliers own SDR roadmap (without customer funded NRC) as well as require customer funding. This section discusses possible future development. The ambition is to port TGR waveforms on the Ra 460 hardware platform or port the Ra 460 waveforms on at least some of the TGR hardware components. The purpose is to ensure a flexible usage of the Ra 460 and the TGR hardware components. The TGR system and the Ra 460 should have some form of interoperability capability, either internally/externally on the IP layer or internally on layer 1 or 2. This assumes a hardware component capable of running two simultaneous waveforms. At present FMV does not have the right of use of the Ra 460 waveforms and hence the porting activity depends on the involvement of Rockwell Collins. FMV may in the future be interested to port the ESSOR or the COALWNW waveforms on the TGR radio hardware components. FMV will have the right of use on both the ESSOR and the COALWNW waveforms. Interoperability between the future PRR radio and the TGR system may be of interest and might require some form of WF PRR. A time schedule showing tentative upgrades (focus on waveforms) is shown in Figure 6

16 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 16 (41) Figure 6. Time schedule showing tentative upgrades. Note that there might be demands on upgrades on the system that are not directly associated with porting a new waveform. The Suppliers own road map to add enhancements as well the availability to support custom enhancement requirements are of great interest. 2.3 Waveforms The waveforms to support the TGR requirements are in this RFI defined as TGR waveforms. Expected ranges vary depending on waveform type, used bandwidth, hardware components etc to support different use cases. Ranges will be stated as requirements on path loss in the RFQ. It is understood that some standardized waveforms (STANAG based etc) are available in the Suppliers offered system. Some interoperability should exist between the TGR waveforms and existing standardized waveforms on the system level (not on the over-the-air interface). Seamless IP communication between waveforms shall be supported at a radio node having two or more TGR waveforms instantiated. The routing of IP traffic between different waveforms may be handled internally or externally to the TGR system. The waveforms shall be capable of operating in rural, urban, dense vegetation and littoral environments.

17 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 17 (41) The waveforms shall support mobile nodes with speeds up to 70 km/h and should support helicopter usage with speeds up to 200 km/h. Each waveform should be capable of operating in a backbone mode with the purpose to relay data between different partitions of nodes that do not have direct RF contact with each other. It is expected that the waveforms are flexible and offer different configuration capabilities to enable tailoring of performance/functionality of each waveform. At present time, FMV foresees the need of two waveforms, one wideband and one narrowband. Some waveform performance related information is also given in section Wideband waveform A wideband waveform is needed to provide high capacity that will require wideband channels. The range will be typically 2 5 km between each node pair depending on hardware components, used bandwidth etc. The wideband waveform is to be used for BMS type of data traffic and voice. Network sizes up to 140 nodes shall be supported by the wideband waveform. The wideband waveform shall support data transfer using relaying nodes. Each node in the network shall be able to act as a relaying node. Relaying over at least five (5) RF hops shall be supported. The wideband waveform shall be self-organized and use automatic routing on the wireless network to handle changes in connectivity due to mobility and topography. The wideband waveform shall be possible to be used on radio hardware components supporting use cases II and III. The wideband waveform should be possible to be used on all radio hardware components of the TGR system Narrowband waveform A narrowband waveform is needed to provide a range of 5 10 km and beyond using the VHF band with narrow channels (e.g. 25 khz and 50 khz).

18 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 18 (41) The narrowband waveform shall be able to transfer voice (VoIP) data including transfer of small data (BMS) packets with low intensity. The narrowband waveform shall be able to transfer limited amount (various packet sizes but low intensity) of ordinary IP (BMS) data. The narrowband waveform shall be possible to be used on all radio hardware components of the TGR system. The narrowband waveform should support ad hoc relaying using multiple RF hops. The requirements when using multiple RF hops are not defined in detail but the aim is to handle: Transfer of small data packets. A few simultaneous voice sessions. Low latency data transfer in networks with low number of nodes. 2.4 Frequency usage It should be possible to use the narrowband (NB) waveform in the frequency range MHz. It may also be of interest to use the narrowband waveform on frequencies up to 800 MHz as well as MHz. The frequency bands MHz and the MHz must be available for use. The narrowband waveform is intended for operation in 25 khz bandwidth channels. The narrowband waveform should also be able to use 50 khz bandwidth and potentially wider bandwidths in 25 khz steps. It shall be possible to use the wideband (WB) waveform in the frequency band MHz. Limitations in coverage to MHz may be acceptable. It may be of interest to use the wideband waveform in the frequency band MHz as well as MHz. The wideband waveform bandwidth should be configurable between 500 khz to 5 MHz, depending on needed data capacity and allowed bandwidths. When using STANAG standardized waveforms the platforms shall handle corresponding frequencies and bandwidths used by these standards.

19 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 19 (41) The frequency assignment authority often restricts the maximum output power depending on frequency band and bandwidth. To enable Supplier response on question of max path loss a max allowed power of 50 W is to be used. Simplex frequency operation will be used. However it may be of interest to use duplex transmitting and receiving frequencies. 2.5 Voice and data handling All user data to be transferred by the radio system shall be based on IP. The primary mode of voice handling is secure voice where the encryption is done externally using the Soldier Node and the voice is provided to the radio as aggregated IP packets. The Soldier Node will not add any red side IP addresses and potentially use Secure Communication Interoperability Protocol (SCIP), or similar methods to reduce encryption related IP header overhead on the black side (to the radio). The protocols RTP and UDP are used when transferring the voice packets. This relates to secure voice operation. A secondary mode of voice handling is un-secure voice where no external encryption is used and the voice traffic is provided using headset or handset directly connected to the radio. In this case analogue voice input may be used. The voice handling requirements discussed below relates mainly to the secure voice mode of operation. Where applicable, requirements on un-secure voice handling will be similar as for secure voice handling. The narrowband waveform shall be capable of transferring 3-6 simultaneous voice sessions using one radio net (same set of frequencies, TRANSEC seed/key etc). The present assumption is that voice sessions are identified based on DSCP tagging using preconfigured addresses and transferred as aggregated IP multicast packets. A voice session typically corresponds to a Platoon voice net or a Company voice net. The radio distinguishes between voice (VoIP) and other IP (BMS etc) data by use of different DSCP tagging and used IP addresses. The turn-around time between speakers in each voice session is an important user requirement and should typically be less than one second. If needed the setup of a voice session is handled externally to the radio. Some data traffic due to externally applied protocols (SIP, SCIP etc) may be transferred via the radio.

20 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 20 (41) In addition to the voice traffic the narrowband waveform shall be capable of transferring position information at a rate of one position per minute per node. The number of nodes in a radio net supporting simultaneous voice sessions and position message distribution is typically 50 nodes. The packet size of a position message is typically less than 800 bits including IP headers (IPv4). The position information is externally supplied as IP packets. The wideband waveform shall support low latency (typically less than 0.5 s) transfer of small data packets (up to 1000 bits) between one hop neighbors. BMS data traffic is defined as transfer of C2I IP packets with varying size. The traffic intensity varies over time and with time periods where many nodes sends data traffic. Most of the traffic is sent as multipoint-to-multipoint. Some pointto-point traffic may occur. Transfer of video and similar data should be possible using the wideband waveform in certain scenarios. A figure of acceptable Message Completion Rate (MCR) will be defined based on different conditions such as, traffic type, multipath channel, jamming etc. Initially the MCR requirement would be about 90 % in a defined connected multi-hop scenario and % in defined one hop scenario assuming IP packet sizes between bytes. The requirement on MCR for voice traffic is under investigation but may be as high as > 99.9 % when using packet sizes of bits. 2.6 IP handling Discussions are on-going whether the TGR system shall act as a layer 3 based component or as a layer 2 based component on the external data interface. Depending on decision and availability of supported standardized protocols there will be different requirements on the TGR system. The following protocols may be needed, depending on support of layer 2 or 3 functionality. The TGR system should act as a switch and support protocols such as DLEP, R2CP etc. ICMP, IGMP, OSPF, SNMP, HTTPS, FTP, IP Some IP multicast routing protocol may need to be supported.

21 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 21 (41) When connected to a Soldier Node, the TGR node may need to support static IP address configuration (including multiple IP addresses). DSCP handling shall be supported. Support of IPv6 will be required. 2.7 TRANSEC and security related functions The radio system shall be capable of operating in a hostile jamming environment. This will be defined as requirements on jamming protection. This together with other threats will result in requirement on a TRANSEC capability. Since communication using the same waveform between nodes of different radio hardware components shall be possible a common approach regarding the TRANSEC implementation is needed. This implies that the same algorithm, keys and seed shall be supported in all hardware components. It is preferred that TRANSEC keys are loaded via an external key fill device on a dedicated interface on the radio. It is preferred that an external key fill device provided as Government Furnished Equipment (GFE) can be used. It should be possible to erase loaded TRANSEC keys. The implemented TRANSEC functionality needs to be approved by the Swedish NCSA (National Communications Security Agency) authority. This requires that the Swedish NCSA has the possibility to review the implementation of the TRANSEC functionality, e.g. by reviewing design documents and TRANSEC related source code There will be requirements on authentication between radio and the management PC as well as signing of files to be loaded and exported to/from the radio. Where applicable also requirements on a security log function exist. There will be demands on reviewing design documents and in some cases source code as a way to fulfill the acceptance process required by the Swedish NCSA. The review is facilitated if methods like Common Criteria (CC) are applied.

22 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 22 (41) 2.8 Cosite handling Cosite interference may occur when several radios are installed in the same platform, depending on number of radios, used waveforms etc. It will be the responsibility of the Supplier to guarantee fulfillment of range requirements etc within the TGR system when several radios/waveforms are deployed in the same vehicle. Below are some examples of cases that need to be supported: Several radios on the same platform using the same waveform but different radio nets. Several radios on the same platform using the different waveforms. Several different radio hardware components installed on the same platform. Cosite handling with other radio systems installed on the same platform. In addition to the TGR waveforms there might be standardized waveforms that operate on some of the TGR radio hardware. The performance of these standardized waveforms should be un-interfered while using TGR waveforms as well as having minimum effect on the range of the cosited TGR waveforms. The answers to the questions in section 3.7shall be based on an antenna isolation of 20 db using the same frequency band and 40 db when waveforms use different frequency bands. Supplier when answering the cosite related questions in section 3.7, shall use the scenario described in Figure 7.

23 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 23 (41) Figure 7. Cosite scenario to be considered when responding to the questions in section 3.7. In this scenario four waveforms are used in the same vehicle. Two of the waveforms are transmitting and two waveforms are in receiving mode. The NB waveform is operating on VHF and the WB waveform is operating on UHF. All transmitters use 50 W of output power. 2.9 Management and configuration Management and configuration includes a number of activities such as: Monitoring of performance, BIT, alarms etc in real time. Selection of different operating alternatives in real time, Configuration of radio nets. Loading of configuration data, Extraction of log files. Security related handling. The management and configuration shall be simplified and the same tools and methods shall be possible to use regardless of radio hardware component and waveform. The need of a configuration tool that covers all equipment (radios, routers, BMS system etc) within a Battalion is increasing. The configuration method

24 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 24 (41) and tool used for the TGR system shall be possible to interface with such a Battalion configuration tool. This may be done using a well defined interface. In some scenarios (when connected to the Soldier Node) there might be demands on SNMPv3 information/alarms from the radio transferred on the same interface as used to transfer user data.

25 (RFI), T RFI TACTICAL GROUND RADIO SYSTEM 25 (41) 3 Requested Technical Information If no response is given on certain questions FMV will conclude that the Supplier does not support the requirement in question. 3.1 General The Supplier is requested to reply with the following information: Overall description of offered system solution including radio hardware components, waveforms etc and how these may be combined to a complete system meeting the TGR requirements and use cases outlined in section 2.
