Wireless Device ServerIntroduction to wireless device server
A device server is used to control the serial data from serial interfaces such as RS 232, RS 422, and RS 485. Its usage in Ethernet frames is common. It distributes the serial information across a TCP / IP network. The major benefit of a device server is its utilization of the existing bandwidth of the existing Ethernet connections. The result is the considerable amount of serial cable savings.
Benefits of Wireless Device Server
A wireless device server is embedded with the wireless IEEE 802.11b or 802.11g specifications based integrated interface. This is the interface that a wireless device server uses to transmit data within a wireless local area network (WLAN). A wired device server uses RJ 45 connectors. A wireless device server offers the device server adds to these wired wireless server advantages.
Wireless Device server is cost effective over cables
First of being wireless WDS (wireless device server) is cost effective relatively to the cables. Cables are suitable only for the static implementation. But in the industrial control or automation there is no fixed implementation of cables that costs to a substantial amount. Secondly the areas where temporary cables are required such as conferences halls. And also unsafe areas where cables are installed on the risk of hazards.
Wireless Device Server supports the existing data routing schemes
The serial data transmission in the Ethernet based networks is made through IP routing. A wireless device server supports the same IP addressing schemes as the wired ones. So a wireless device server also offers the flexibility to be integrated into a system without any difficulty. This also allows its integration in the Internet and WAN (wide area network).
Wireless Device Server allows feasibility in moving equipment or machinery
Instrument trolleys, cranes, forklift trucks are one major portion of the industrial control or automation. The problem occurs in their movement at peak times mainly because of the cable installation. This again affects the cost of the industry. The easy solution is to deploy a wireless device server. This relieves you from the headache of mobility of devices.
Wireless device server offers the same functionality as radio modems but in full duplex mode
You can use a radio modem to transfer data between to serial devices. But being half duplex in nature radio modems cannot be implemented for full duplex transmission effectively and efficiently. A wireless device server eliminates the same problem with added benefits. These added benefits include extensive and efficient error checking, relatively higher data rates, and most importantly multiple connections utilizing the same radio space.
