Cisco Aironet Access Point Deployment Guide

Note: Avoid using single‐band (single‐radiating element antennas) like those used with the earlier AP 3500, because they are not fully compatible with the newer AP 1600/2600 and AP 3600. Antennas for the AP 1260 and the AP 3500 are single‐radiating element antennas made for each individual band. The AP 3600, 2600, and 1600 use dual‐band, dual‐radiating element antennas and are branded with an orange marking. (See Figures 46 and 47.)

When using 802.11n rates in areas with high metal, such as distribution areas or airport hangars, lower gain antennas on the ceiling may perform better because they tend to radiate the signal in all directions and increase the chance that multi‐path will enhance the signal. If you have a clear path, a patch antenna at the end of an aisle at roughly the same height or just above the (WLAN client) is preferred. (See Figure 49.) Be sure to do a site survey.

Figure 49: Importance of Site Survey in Areas with High Amounts of Metal

A high gain antenna may have a null or dead spot directly below it because the antenna element is often much longer and has less metal surface area available to conduct the radio wave if you are directly underneath it. (See Figure 50.) The further away you are from the antenna, the more surface is available, and the better it performs.

Cisco Systems 1600 series routers are well-regarded in the networking industry for their reliability, versatility, and performance. Designed to meet the needs of small to medium-sized businesses, the Cisco 1600 series is primarily oriented towards providing robust connectivity for branch offices and remote sites.

One of the most significant features of the Cisco 1600 series is its modular architecture. This allows users to customize their routers with various interface cards, enabling support for different types of WAN technologies, including serial, ISDN, and Frame Relay. The modular design not only enhances flexibility but also extends the lifespan of the equipment, as businesses can upgrade their capacity and functionalities according to evolving demands.

Another key characteristic of the Cisco 1600 routers is their advanced routing capabilities. These devices support a wide range of routing protocols, including RIP, OSPF, EIGRP, and BGP. This versatility ensures seamless integration into existing network infrastructures, facilitating the scalability and adaptability that modern networks require.

Security is also a crucial aspect of the Cisco 1600 series. Incorporating features such as access control lists (ACLs) and support for Virtual Private Networks (VPNs), these routers help businesses safeguard their sensitive data during transmission. Enhanced security features allow companies to implement secure remote access for employees, thereby maintaining productivity without compromising safety.

In addition to routing and security, the Cisco 1600 series boasts Quality of Service (QoS) capabilities. This technology enables better management of network traffic, ensuring that critical applications receive the bandwidth they need for optimal performance. By prioritizing important data flows, businesses can enhance user experience and minimize disruptions across their network.

The Cisco 1600 series routers are also equipped with user-friendly interfaces and management tools. Cisco's IOS software platform provides a command-line interface (CLI) and web-based graphical interface for straightforward configuration and monitoring. This simplifies network management tasks and reduces the learning curve for IT personnel.

In summary, the Cisco Systems 1600 series routers offer a significant combination of modularity, robust routing protocols, enhanced security measures, Quality of Service features, and user-friendly management options. These characteristics make them an excellent choice for small to medium-sized enterprises looking to establish a reliable and secure networking infrastructure. With the continued evolution of networking technologies, the Cisco 1600 series stands as a dependable solution for businesses navigating an increasingly complex digital landscape.
