Cisco Aironet Access Point Deployment Guide

Note: In order to beamform to clients using three spatial streams, since three transmitters are used in the transmissions, the AP needs at least one additional radio to beamform. The AP 3600 has four radios per band and can beamform to clients using three spatial streams.

To summarize, ClientLink 2.0 takes the received signals heard from the client on the uplink and calculates how the multipath signal looked from those streams. Then, on the reciprocal side (transmit downlink), ClientLink 2.0 uses all four radios to figure out the optimal way to form the signal (transmit beamforming) to enable the client to best decode (receive the signal on the downlink) with the least amount of retries.

ClientLink 2.0 with an AP 3600 enables beamforming to all 802.11n clients, including 3SS clients, and can do so for up to 128 clients at a time. The AP 1600 supports fewer clients (32) and does not support 3SS. ClientLink 1.0 supported a maximum of 15 clients at a time. ClientLink 2.0 significantly improves throughput and coverage up to 60% on the downlink side for much better 802.11n client connectivity and for enhancing the Bring Your Own Device (BYOD) experience.

Site Survey Considerations

While ClientLink dynamically beamforms and helps to maintain a robust signal, which results in fewer retries, it was not designed to change the cell range. ClientLink creates a better connection experience, not a larger cell size.

For this reason, during a site survey, it is important to keep in mind that the AP 3600 cell sizes are generally the same or very similar to other Cisco access points. Figure 58 depicts typical ranges in the 1‐ 54 Mbps range. While Cisco always recommends that you survey with the equipment you intend to deploy, an earlier survey done with an AP 3500, for example, would not be invalid for an AP 3600 deployment. Figures 59 and 60 provide examples of the modulation types and signal‐to‐noise ratio (SNR).

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.
