Tactical Local Area Network System-TAYAS

TAYAS (abbreviation for tactical local area network system in Turkish) is developed as a solution to local area network communication needs of Turkish Land Forces in tactical area. The system consists of SW and HW installed in local area, operates in cabled and wireless mode and provides a connection for tactical command control and information systems to strategic communication systems such as TAFICS (Turkish Armed Forces Integrated Communication System), tactical communication systems such as TASMUS (tactical area communication system of the Turkish Land Forces) and satellite systems such as TURKSAT.

TAYAS is a tactical local area network (LAN) system, operating in cabled or wireless mode or a combined mode where the two are backing up each other. It is used on the battlefield by military units of the size from an army corps down to a brigade. For each military unit, one TAYAS Server Set (TSS) installed to a vehicle mounted server shelter and a number of TAYAS Network Access Sets (TNAS) to be used at commanding positions are provided. TAYAS Network Access Sets (TNAS) will connect (in a wired or wireless fashion) to the TAYAS Server Set (TSS) to communicate between them and with the outside world. Commanding positions are dedicated vehicles or tents; accordingly TNAS are supplied in portable racks for easy transportation. Number of TNAS in a TAYAS system depends on the size (number of commanding positions) of the corresponding military unit. Typically 7 TNAS are provided for an army corps and 5 for a brigade. Mobile users with portable computers can also connect to the system. Secure wireless communication is provided by use of a "National Secret" encryption algorithm. For this purpose, an encrypted wireless network access device (KKAC), an encrypted terminal wireless access device (TKABC) and a dedicated wireless network management SW are designed and developed by Aselsan, using in house and indigenous resources. The wireless network devices are certified "National Secret" by the Turkish certification authority.


TAYAS System Components

A TAYAS system will be formed of one TAYAS Server Set (TSS), a number of TAYAS Network Access Sets (TNAS), encrypted wireless network access devices (KKACs), encrypted terminal wireless access devices (TKABCs), cabled and wireless network management SWs, portable monitor sets, portable computers for mobile users, antenna masts and various connection cables. Racks, boxes and various mechanical parts will also be supplied with the system, for vehicle installation, mounting and securing of the material.

The vehicle mounted server shelter will contain a TAYAS Server Set (TSS), a portable monitor set, an antenna mast and cabled and wireless network management SWs. Commanding positions will be provided with a TAYAS Network Access Set (TNAS), and an antenna mast. Mobile users will connect TKABCs to the USB port of their portable computers for mobile access to the network.

TAYAS Server Set (TSS): TSS is the center of the TAYAS system. Each military unit will have a vehicle mounted server shelter containing a TSS. Users in the military unit (users in the LAN), can use the TSS for data communication, file transfer or access to a wide area network (WAN). A typical TSS consists of servers, Ethernet switches, routers, Firewalls/Intrusion Prevention Devices, UPS and KKAC.

TAYAS Network Access Set (TNAS): This component is used to connect the commanding positions with their cabled and wireless users to the TSS hence to the TAYAS system. Connection to the TSS can be cabled or wireless. TNAS are supplied in portable racks for easy transportation, so they can be moved from one commander's vehicle to another or installed in a tent. A typical TNAS contains an Ethernet Switch, UPS and KKAC.

KKAC and TKABC: Encrypted wireless network access device (KKAC) and encrypted terminal wireless access device (TKABC), together with a dedicated wireless network management SW, form the wireless network infrastructure of the TAYAS system. KKAC and TKABC have their own pages in the Aselsan internet site.
