Appendix IV- Services

This section provides more details on the system management services.

Ping WatchDog

The ping watchdog sets the device to continuously ping a user defined IP address (it can be the internet gateway for example). If it is unable to ping under the user defined constraints, the device will automatically reboot. This option creates a kind of "fail-proof" mechanism.

Ping Watchdog is dedicated for continuous monitoring of the particular connection to remote host using the Ping tool. The Ping works by sending ICMP “echo request” packets to the target host and listening for ICMP “echo response” replies. If the defined number of replies is not received, the tool reboots the device.

Enable Ping Watchdog: control will enable Ping Watchdog Tool.

IP Address To Ping: enter the target host IP address to monitor.

Ping Interval: specify time interval (in seconds) between to send the ICMP “echo requests”.

Startup Delay: specify initial time delay (in seconds) from device startup or reboot to start sending first ICMP “echo requests”. Minimum value is 60 seconds.

Failure Count To Reboot: specify the number of ICMP “echo response” replies. If the specified number of ICMP “echo response” packets is not received continuously, the Ping Watchdog Tool will reboot the device.

SNMP Agent

Simple Network Monitor Protocol (SNMP) is used in network management systems to monitor network-attached devices for conditions that warrant administrative attention. Device contains an SNMP agent which allows it to communicate to SNMP manage applications for network provisioning.

SNMP Agent provides an interface for device monitoring using the Simple Network Management Protocol (an application layer protocol that facilitates the exchange of management information between network devices). SNMP Agent allows network administrators to monitor network performance, find and solve network problems. For the purpose of equipment identification, it is always a good idea to configure SNMP agents with contact and location information:

Enable SNMP Agent: control will enable SNMP Agent.

SNMP Community: specify SNMP community string. It is required to authenticate access to MIB objects and functions as embedded password. The device supports a Read-only community string that gives read access to authorized management stations to all the objects in the MIB except the community strings, but does not allow write access for device that supports SNMP v1.

Contact: specify the identity or contact in case an emergency situation arise.

Location: specify the physical location of the device.

802.11N specifications

Compex Systems 802.11N solutions are designed to provide high-performance wireless networking, catering to the growing demand for faster and more reliable connectivity in various applications. The 802.11N standard, also known as Wi-Fi 4, significantly enhances the capabilities of previous Wi-Fi standards by utilizing advanced technologies and features.

One of the key characteristics of Compex Systems 802.11N products is their support for Multiple Input Multiple Output (MIMO) technology. MIMO allows the transmission of multiple data streams simultaneously, effectively improving throughput and range. This is especially useful in environments with high user density or physical obstructions, as it enhances the signal quality and minimizes interference.

Another significant feature is the use of Channel Bonding, which combines two adjacent channels to double the data rate. This capability enables users to experience higher speeds, typically reaching up to 600 Mbps under optimal conditions. The dual-band operation, supporting both 2.4 GHz and 5 GHz frequencies, further enhances flexibility and performance. The 2.4 GHz band offers broader coverage, while the 5 GHz band provides faster speeds with less congestion.

Compex Systems also incorporates advanced security protocols in their 802.11N solutions. With support for WPA2 encryption and robust authentication methods, users can ensure that their connections remain secure, protecting sensitive data from potential threats.

Quality of Service (QoS) is another critical feature, allowing network administrators to prioritize traffic according to application needs. This ensures that bandwidth-intensive applications, such as video streaming and online gaming, receive the necessary resources for optimal performance, even in a crowded network environment.

Designed for versatility, Compex Systems 802.11N devices can be employed in various scenarios, including enterprise, education, healthcare, and hospitality sectors. Their compact and durable designs make them suitable for deployment in both indoor and outdoor settings.

Overall, Compex Systems 802.11N solutions offer a comprehensive set of features and technologies aimed at providing robust, high-speed wireless connectivity. With MIMO, Channel Bonding, dual-band support, enhanced security, and QoS capabilities, these systems are well-suited to meet the demands of modern wireless networking environments.
