Wireless local area network applications range from civil to military in many areas. Every network centric process can be carried over wireless networks assuming enough security and reliable connectivity. Wireless Local Area Networks (WLAN) is one of the key technologies from an analysis of the relevant and emerging technologies to provide effective, compatible, and secure C4I systems for Network Centric Warfare (NCW).
6110 TS-WLAN is a broadband wireless technology for mobile connections through access points or independent of the access points. 6110 TS-WLAN is the military extension of wireless networks which focuses security and reliability in harsh environments and considerably long communication ranges. 6110 TS-WLAN system is based on IEEE 802.11 standard with some modifications that overcome the drawbacks of IEEE 802.11. A robust synchronization scheme, antenna diversity technique and a FEC mechanism were added to standard physical layer structure to get better BER performance, extended range and reliable communication links. Furthermore, a powerful security structure was adapted against system and communication security threats.
ASELSAN 6110 TS-WLAN has been successfully integrated to TCP/IP based tactical C3 systems. ASELSAN 6110 TS-WLAN has been operational in Turkish Armed Forces since August 2005.
6110 Tactical Secure Wireless Local Area Network is based on IEEE 802.11 standard that offers two different modes of network operation:
- Ad-Hoc Mode
- Infrastructure Mode
In ad-hoc mode wireless terminals can communicate with their peers directly without any need for central management. When there is no need to access wired networks and instantaneous network setup is required, this mode is desirable. In this mode, up to 32 wireless terminals can communicate with each other directly.
Infrastructure mode requires a central management unit, called access point. An access point is responsible for managing and controlling the wireless network. Since communication is controlled by the access point, this mode is desirable for densely populated wireless networks that may need to access wired network. In this mode, up to 32 wireless terminals can communicate with each other through an access point.
