The CISCO851W-G-A-K9 Cisco 851W 4 Ports Wireless Integrated Services Security Router has several advanced wireless features that provide increased security and flexibility for wireless networks.
One such feature is support for WPA2 (Wi-Fi Protected Access 2) encryption, which provides advanced security for wireless networks. This includes support for the Advanced Encryption Standard (AES) encryption algorithm, which is considered to be one of the most secure encryption methods available.
The router also supports a feature called wireless client isolation, which prevents wireless clients from communicating with each other on the same network. This can help prevent malicious actors from using your network to launch attacks on other devices.
Another advanced feature is the support for wireless LAN (WLAN) controller, which enables centralized management of multiple wireless access points. This allows administrators to easily manage and monitor the entire wireless network, and make changes and updates to the network from a single location.
The router also supports multiple SSID (Service Set Identifier) that allows you to create and manage multiple wireless networks on the same device, each with its own security settings and access controls. This can be useful for separating different types of traffic, such as guest and corporate traffic, and for providing different levels of access to different users.
Additionally, the router supports Quality of Service (QoS) for wireless network. Which allows you to prioritize certain types of traffic and ensure that critical applications, such as voice and video, receive the bandwidth they need.
Power Consumption and Energy EfficiencyThe CISCO851W-G-A-K9 Cisco 851W 4 Ports Wireless Integrated Services Security Router is designed to be energy-efficient, which can help reduce power consumption and costs.
One way it achieves this is through the use of Energy Efficient Ethernet (EEE) technology, which can reduce power consumption when the network is idle. This technology allows the router to automatically adjust its power usage based on the level of network activity, which can help save energy when the network is not in use.
Another way the router is designed to be energy-efficient is through its power supply. The router typically comes with an external power supply unit (PSU) that is designed to be energy-efficient, which can help reduce power consumption and costs.
Additionally, the router can be configured to automatically power off or put into sleep mode during periods of low activity, which can help reduce power consumption and costs.
Furthermore, the router can be managed remotely by using the web interface or SNMP (Simple Network Management Protocol) which allows network administrators to monitor and manage the device remotely. This will allow you to see important information like memory usage, CPU utilization, and interface statistics, which can help you identify any performance bottlenecks or other issues, and also to reduce the power consumption by shutting down the interfaces that are not in use.
High Availability and RedundancyThe CISCO851W-G-A-K9 Cisco 851W 4 Ports Wireless Integrated Services Security Router is designed to provide high availability and redundancy, which can help ensure that your network remains up and running even in the event of a failure.
One way it achieves this is through the use of Cisco's Hot Standby Router Protocol (HSRP), which allows for automatic failover in the event of a failure. HSRP allows for multiple routers to work together to provide a single virtual IP address, which can be used by clients to access the network. If one of the routers fails, the other routers will automatically take over its role, allowing the network to continue functioning.
Another way the router provides high availability and redundancy is through its support for link aggregation, which allows for multiple network connections to be bundled together to form a single logical link. This can help ensure that network traffic can be redirected in the event of a failure, allowing the network to continue functioning.
Additionally, the router supports VPN (Virtual Private Network) capabilities, which allow for secure communication over the internet, which can help optimize performance of remote workers and mobile devices. This can help ensure that users can continue to access the network even if one of the routers fails.
The router also supports a feature called SRST (Survivable Remote Site Telephony), which allows for centralized management of multiple remote sites. This feature allows you to easily manage and monitor the entire network from a single location, and make changes and updates to the network from a single location, which can help ensure optimal performance of your network.
