Codan’s Envoy HF Radio delivers dependable, clear, trouble-free voice, messaging and data communications, without dependence on existing infrastructure. Now with Codan’s second generation Digital Voice technology, Envoy provides outstanding voice clarity in conditions where competing HF radios fail.

 

EXCEPTIONAL DIGITAL AND ANALOG VOICE CLARITY
Codan’s second generation Digital Voice (DV) technology provides a quantum leap in voice communications. It significantly reduces the hiss, crackle, pops, and multipath effects typical of HF. The vocoders used provide voice quality experience that is similar to cellular phones, and the modem technology ensures continued operation in degraded and fading channels. When analog SSB mode is needed, Envoy’s patented Easitalk™ DSP algorithm works to actively remove background noise and interfering tones. During transmission, Codan’s TalkPower feature dynamically compresses and shapes the frequency response of the voice signal to maximise transmit power and intelligibility. A syllabic squelch only opens the speaker mute when speech signals are present to eliminate background noise.

 

SOFTWARE-DEFINED ARCHITECTURE
Envoy uses latest-generation high-performance Digital Signal Processor (DSP), Field-Programmable Gate Array (FPGA) and microprocessor technology. This provides market-leading performance and future upgradability through software updates to install new capabilities and support evolving standards.

 

IP / ETHERNET / USB CONNECTIVITY
Envoy IP / Ethernet connectivity enables centralised programming, maintenance and operation of network connected stations. Envoy handsets and consoles include USB ports for convenient programming and maintenance via conventional USB cable connection or via attached memory stick.

 

QUICK DEPLOYMENT AND INTUITIVE OPERATION
Envoy start-up wizard guides the installer though entry of frequencies, calling system set-up, contacts and peripherals. Alternatively, Codan’s Windows-based TPS-3250 Radio programming software can be used to build profiles, which can be conveniently deployed via direct connection, IP or USB memory stick. Once profiled, Envoy can be easily locked down using an administrator PIN, ensuring important settings are not tampered with. Envoy’s large high-resolution, sunlight readable colour display, and intuitive menu system makes operation similar to modern smartphones. Making calls is as simple as navigating to your contact list, locating the desired contact and pressing the “call” button. Other common actions are supported through customisable hotkeys for single or multiple step operations. For optimal user safety, Envoy includes a dedicated Emergency key. This can be configured to automatically contact one or more stations, embedding the Envoy’s GPS coordinates into the emergency signal. To minimise training burden for non-English speaking users, Envoy’s user interface is also made available in a variety of other languages.

 

UNPARALLELED RF PERFORMANCE
Envoy’s strong RF performance is paramount to effective long range communications. Unlike many Software-Defined Radios, Envoy provides specifi cations superior or equal to high-end analog products. For example, to maximise range, receiver sensitivity is a massive -125 dBm, and blocking is greater than 100 dB, minimising chances of interference from adjacent stations. Envoy’s transmitter is also extremely clean, with carrier, spurious and harmonics more than 65 dB below PEP. Envoy also supports connection of dual antennas for short and long range propagation.

 

ALE AND SELCALL CALLING CAPABILITY
Envoy supports current calling standards including CCIR compliant Selcall, FED-STD-1045 Automatic Link Establishment (ALE) and MIL-STD-188- 141B ALE. Envoy enables concurrent operation of different calling systems, and automatically optimises channel scan times. This ensures full interoperability with earlier generation Codan, competitor and legacy radios. Selcall provides the capability to voice or message call an individual radio, group of radios, or broadcast to all radios. ALE also provides these capabilities, plus built-in intelligence to automatically select the optimum channel (frequency) to ensure the best chance of linking and the clearest signal. The MIL-STD ALE option adds NET calling (similar to Talk groups), on-air Link Quality Assessment (LQA) exchange, and advanced addressing types. Envoy’s ALE also includes Codan Automated Link Management (CALM™). This technology is fully compatible with conventional standards-based ALE, but includes significant proprietary enhancements to improve performance. As an example, ALE LQA is internally recorded in a three-dimensional matrix against time. This results in far reduced on-air soundings and improved probability of linking. CALM™ also includes special call types including “fi rst-in-list” for fastest possible link, and “best-in-list” for optimised data.

 

INTEGRAL DATA CAPABILITY
Envoy supports MIL-STD-188-110A/B high-speed data operation up to 9600 bit/s. The modem uses interleavers, tone-excision and turbo-decoding for optimum performance in diffi cult channels. When combined with Codan’s STANAG 5066 compliant RC50-C Email software, email over HF can be achieved from standard SMTP/ POP email clients such as Microsoft® Outlook. Emails are automatically compressed and the data rate is optimised to channel conditions. Envoy also supports Codan’s robust low-rate data modem waveform, which is compatible with our 3012 / 3212 external modems. This modem supports data operation to 2400 bit/s (typically 6000 bit/s including compression). It’s available with Windows based Email / Chat software, or can be used for custom data / telemetry applications via its standards-based AT command interface.

 

ENCRYPTION
Envoy has a choice of encryption options to suit the required level of communications security. For communications up to “top secret” classification, AES 256-bit security is available for both Digital Voice and data encryption, supported with up to 256 internally pre-programmed encryption keys For voice only applications, Codan’s CES-128 DSP-based encryption option is available, with up to 97 16-digit user programmable keys. An additional layer of security is provided by assigning a PIN number during a secure communications session. Both of these options are supported by Codan’s Key Management Software (KMS) application suite, which enables generation, management and deployment of keys. For convenience, keys can also be filled using a conventional USB memory stick .For basic voice security, the CIVS option provides a 32 code DSP-based scrambler. All voice encryption options for Envoy can be activated by a single hotkey, and are fully integrated with core Radio functions like Selcall and ALE scanning to ensure simplicity of operation. It is also possible to configure Envoy to automatically enable encryption on specified networks.

 

GPS SUPPORT
Envoy supports connection of GPS via NMEA0183 compatible GPS receivers. This enables polling and sending of GPS positions over air. Distance and bearing to other users or programmable waypoints can be displayed on an intuitive graphical display. When used with mapping software deployed mobiles vehicles can be graphically tracked.

 

VERSATILE DESIGN FOR MOBILE, BASE AND COMPLEX SYSTEMS
Envoy is designed using a modular approach, with a handset for mobile applications and a desk console for bases. The use of IP over Ethernet enables geographical separation of radio and console, without the need for expensive adaptor devices. Envoy can also be supplied in rapidly deployable cases.

P25 BENEFITS

Interoperability

Radio equipment that is compatible with P25 standards will allow users from different agencies or areas to communicate directly with each other. This will allow agencies on the federal state/provincial or local level (or any other agency) to communicate more effectively with each other when required (emergencies, law enforcement, etc.)

Multiple Vendors

The P25 open standard will allow competing products from multiple vendors to be interoperable. This will allow customers of the P25 product to benefit from multiple manufacturing sources (decreased costs, open bidding, non-proprietary systems).

Backwards Compatibility

A basic requirement for Phase 1 P25 digital radio equipment is backward compatibility with standard analog FM radios. This supports an orderly migration into mixed analog and digital systems, enabling users to gradually trade out radios and infrastructure equipment. By selecting products and systems that comply with P25 standards, agencies are assured that their investment in the latest technology has a clear migration path for the future.

Encryption Capability

The P25 standard includes a requirement for protecting digital communications (voice and data) with encryption capability. The encryption used in P25 is optional, allowing the user to select either clear (un-encrypted) or secure (encrypted) digital communication methods. The encryption keys also have the option of being re-keyed by digital data over a radio network. This is referred to as Over the Air Re-keying (OTAR). This capability allows the radio systems manager to remotely change encryption keys.

Improved Audio Quality

With 2800 bits per second of the total 9600 bits per second channel capacity allocated to error correction, P25 digital signals have improved voice quality over standard analog signals, especially at low or noisy RF carrier levels. The IMBE™ voice coder converts voice information into digital data and then the data is protected using error correction codes. The error correction is able to correct for small errors in the received signal. Since the audio is digitally encoded, the background noise typically present in analog systems is also removed.

WHY HF RADIO?

High Frequency (HF) radio is used for first-line and backup communications over long distances, mainly in remote regions of the developed world and in developing countries.

Government and private organisations are continually searching for the most flexible, reliable and cost effective solutions for their remote, emergency and security communications needs. 

In today’s world of instant voice, email, messaging, fax and GPS navigation, what has High Frequency (HF) radio to offer? Surprisingly perhaps, HF radio provides all of these options and has several important advantages over other communications media.

HF radio will never replace fixed and mobile telephony as the first communications option for the general public, but for organisations involved in emergency, remote and military communications it is a vital and irreplaceable wireless communications tool. 

LONG RANGE COMMUNICATIONS CAPABILITY

Whilst VHF and UHF radio is also commonly used for short-range line-of sight (LOS) communications, only HF is capable of communicating over distances of 3000 km or more. 

MINIMAL INFRASTRUCTURE REQUIREMENTS

Unlike conventional, Voice over IP (VoIP), cellular and satellite telephony, which all rely upon land-based infrastructure, an HF radio network requires minimal infrastructure. As such it is often the only reliable means of communication when disaster strikes. 

FULL MOBILITY

HF radio is simple and quick to deploy and provides communications capability for users no matter where they are. Fixed base stations can be used to communicate with other bases or to provide command and control for mobile (vehicle-mounted) and portable (manpack) users in the field.

INTEROPERABILITY

HF radio can be used to communicate with existing VHF and UHF radio systems, cellular telephones and land-based telephones through developments in cross-patching technology that make this as easy as dialling a telephone number. 

LOW COST OF OWNERSHIP

Compared with satellite telephony, the most common alternative technology for communications of last resort, HF radio is the economical choice. Once the initial investment in equipment is made, there are no call costs or ongoing monthly line or equipment rentals. Also, HF radio equipment is built tough to withstand the extreme conditions, which proves to be very cost-effective. 

COMMAND AND CONTROL

The nature of emergency planning requires that simultaneous communications be made to and amongst a number of operators in a command and control style network. This facilitates situational awareness amongst the users and external organisations that can also be included in the network. HF radio provides this capability in all base station, mobile (vehicle-mounted) and portable manpack configurations of the radio network.

SECURITY OF COMMUNICATIONS

Where communications are sensitive, HF radio offers technologies to ensure the security of voice and data transmissions. The military uses HF radio as its primary communications medium and from the military have come a number of enhancements in voice encryption and frequency hopping which guarantee secure communications. For non-military use, different levels of encryption are available to suit the individual organisation’s security requirements.

WHAT’S THE DIFFERENCE BETWEEN HIGH FREQUENCY (HF) & LAND MOBILE RADIO (LMR)?

The main difference between HF and LMR is the frequency range:

HF
The HF frequency band is 3 – 30 MHz. HF radios are long range radios capable of communicating beyond-line-of-sight (BLOS) without pre-installed infrastructure.

LMR
LMR encapsulates the VHF (30 – 300 MHz), UHF (300 – 3000 MHz) and 700 MHz, 800 MHz and 900 MHz frequency ranges. LMR equipment such as handheld or vehicle radios are generally limited to line-of-sight, up to around 50 kms (30 miles). LMR systems often use a network of repeaters to produce greater range.
