Introduction

Link-16 does not significantly change the basic concepts of the tactical data link information exchange.

Provides technical and operational improvements to existing data link capabilities.

Link-16 uses Joint Tactical Information Distribution System (JTIDS) and the Multi-Functional Information Distribution System (MIDS) terminals (which are the communication component of Link-16)


Link 16 Terminals

Joint Tactical Information Distribution System (JTIDS) JTIDS refers to the communications component of Link 16 and

includes the Class 2 terminal family software, hardware, and RF equipment.

Multifunctional Information Distribution System (MIDS) MIDS also refers to the communications component of Link 16

and includes the MIDS Low Volume Terminal (LVT) 1, LVT 2 and LVT 3 family of terminals’ software, hardware, and RF equipment.

MIDS Joint Tactical Radio System (JTRS) Software configurable tactical radios providing LOS/BLOS Link

16 and other C4i communication capabilities to the warfighters.

Small Tactical Terminal (STT) STT is a new generation of Link 16 and V/UHF Data radio that is

designed for the tactical edge user. Smaller size, weight, and power make it a perfect fit for mobile ground/surface and light aircraft applications.


Link 16 Features

Link 16 includes many features that improve data exchange normally seen on Link 11 Jam resistance Improved security Increased data rate Increased amounts and granularity of information

exchange Digitized, jam-resistant, secure voice capability Relative Navigation Precise Participant Location and Identification

(PPLI) improvement


Link 16 Architecture

Architectural Characteristics TDMA Format Nodeless Architecture Message and Transmission Security Spread Spectrum, Frequency Hopping

Waveform in the UHF Lx Band


Link 16 Features

Link 16 uses Time Division Multiple Access (TDMA) Automatic function of the Link 16

terminals that uses time interlacing to provide multiple communications nets.

Each JU uses pre-assigned sets of time slots to transmit their data and receive data from other units.

TDMA uses Epochs, Frames, and Time slots as a means of dividing time.


The Network

TDMA Division of Network Time

1 Day = 24 hours 1 Day = 112.5 Epochs 1 Epoch = 12.8 min 1 Epoch = 64 Frames 1 Epoch = 98k time slots 1 Frame = 12 seconds 1 Frame = 1,536

Timeslots (3 sets of 512)

1 Timeslot = 7.8125 msec


Link 16 Features

Nodeless A Node is a unit needed to establish and maintain

connectivity. Link 11 Net Control Station (NCS) is a Node for the link operations. If the NCS or Node goes down, the link goes down as well. Link 16 does not require a Node to establish and maintain connectivity. Link 16 uses Timeslots as part of the TDMA protocol to exchange information regardless on who enters and exits the link.

Link-16 does include the idea of a “Net Time Reference” (NTR), but this can be a redundant entity and the network can operate effectively for a time if the NTR drops out.


Link 16 Security

Message Security MSEC is a crypto variable used to encrypt the message

data the terminal is processing from the host Transmission Security

The TSEC is a crypto variable used to control specific features of the Link 16 waveform.

• Frequency Hopping Pattern• Amount of Jitter• Pseudorandom pattern of noise mixed with the signal prior

to transmission

Cryptographic Keying These security settings are stored in a set of

cryptographic “keys” that must be loaded into the terminal prior to operation on the network

• Link-16 terminals will not transmit without a valid crypto key load


Link 16 Frequency Spectrum

Link 16 is in the Lx Band of the UHF spectrum. Link 16 uses 51 frequencies within 960-

1215 MHz band for transmissions. The frequency is not held constant and uses a pre determined hopping pattern to aid in anti-jam capabilities. The frequency is changed every 13 microseconds.• Because Link 16 uses UHF transmissions, you

are limited to each units’ LOS.

The Link-16 Network• FRAME: the basic unit of recurring time for LINK-16• Each FRAME is 12 seconds in length composed of

1536 timeslot– Each timeslot is 7.8125 milliseconds (msec)– Three sets of 512 timeslots each – sets A, B and C– Each timeslot has a designation, such as: A-0, B-123,

or C-512

Net Entry Link-16 uses Specific messages to achieve

synchronization between terminals on the network

“COARSE SYNC” is achieved by terminals hearing J0.0 “Initial Entry” message transmitted in timeslot A-0.

• This ensures the terminal has the correct cryptographic key settings and has line-of-sight to the network NTR.

• Terminals in COARSE SYNC can receive but not transmit messages

“FINE SYNC” is then achieved by the passing of special messages called Round Trip Timing messages between the user terminal and the Network Time Reference.



Link 16 Features

Round Trip Timing User Terminal

• Transmit an RTT Interrogation (RTT-I) in the beginning of the slot and receive an RTT Reply (RTT-R) later in the slot.

Net Time Reference (NTR):• Receive an RTT-I in the beginning of the slot and transmit an

RTT-R later in the slot.

EXAMPLE WITH 3 OPERATING NETS OPERATING DIFFERENT HOPPING PATTERNS


Relay Transmitting received link 16 information in one or more

timeslots then later transmitting this information in other timeslots.

Relay modes:• Paired Slot Relay – Most basic type of relay. Contains 6 types of

relay functions.• Repromulgation Relay – Used by ground platforms when LOS does

not exist and a relayer is not available• Addressed Relay -- Used with specific needline participation groups.

Useful when multihop relay is required to meet the desired functional connectivity

Voice Link-16 supports dual-channel voice circuits

• Can run at 16Kbps or 2.4Kbps to support multiple national formats• Requires about ¼ slot utilization of the frame• Only works when the terminal is in the network

Access Modes Link 16 also has several access modes to exchange data and

increase the number of users.• Dedicated Access Mode – one slot, one transmitter• Contention Access Mode – one slot, multiple possible transmitters• Time Slot Reallocation – one slot transmitting from a “pool” of

transmitters



Network Participation Groups: Link 16 uses these to allocate network capacity per

user based on the functions users would like to participate in. These NPGs act as virtual circuits to exchange specific assigned data.

A maximum 512 groups can defined, many are set for common use in functional areas:

• RTT (NPG 2 & 3)• Precise Participant Location and Identification (PPLI)

and Status (NPG 5 & 6)• Surveillance (NPG 7)• Electronic Warfare (NPG 10)• Weapons Coordination (NPG 8)• Air Control (NPG 9)• Fighter to Fighter (NPG 19, 20)• Secure Voice (NPG 12 & 13)



Link-16 Networks are defined prior to use – in general Link-16 is NOT an ad-hoc capability Network Design Facilities (NDFs) are defined for each country

and service in each country and are responsible for setting up the Networks for exercise and operational usage.

A Network Design tool such as JNDA or TNDL generates the network design and specific Network Data Load (NDL) files for each terminal on each platform.

Link 16 Next Steps

There are around 5,000 Link-16 capable terminals in the world and the number will continue to grow However, the interest is now in dual- or multi-usage

terminals that give multiple datalink capabilities

Most users still consider Link-16 as a “backbone” communications technology

Link-16 Sustainment Programs funded beginning next year Frequency Remapping – enabling the number of

frequencies to be changed based on other needs

Enhanced Throughput – enabling more capacity per each timeslot’s worth of data

Modernized Crypto – enabling a cryptographic upgrade for more diverse security protocols
