5.0-GHz (802.11h) Radio Features

The 5-GHz radio supports only 20-MHz channelization. In addition, the 5-GHz radio supports Dynamic Frequency Selection (DFS) and Transmission Power Control (TPC) in the ETSI and FCC regulatory domains.

For more information about DFS and TPC, see Radio Channels and Transmit Frequencies at http://www.cisco.com/en/US/products/hw/routers/ps272/products_installation_and_configuration_guid es_list.html.

Note 802.11h is supported only in the ETSI regulatory domain.

Note By default, the C3205 WMIC uses the right antenna to receive and transmit data.

5.0-GHz (802.11h) Channels

The 5.0-GHz (802.11h) radio in the Cisco 3200 Series router (currently available as the Cisco 3205 WMIC) supports the following channels and frequencies in the ETSI regulatory domain:

•5.250 GHz to 5.350 GHz: 5260 MHz (52), 5280 MHz (56), 5300 MHz (60), 5320 MHz (64),

•5.470 GHz to 5.725 GHz: 5500 MHz (100), 5520 MHz (104), 5540 MHz (108), 5560 MHz (112), 5580 MHz (116), 5600 MHz (120), 5620 MHz (124), 5640 MHz (128), 5660 MHz (132),

5680 MHz (136), 5700 MHz (140). (Channels 52 through 140 are ETSI outdoor channels.)

North America customers can use only the following frequencies in the 5.725-GHz to 5.850-GHz band:

•5745 MHz (149)

•5765 MHz (153)

•5785 MHz (157)

•5805 MHz (161)

•5825 MHz (165)

Note By default, the C3205 WMIC performs automatic channel selection on the radio interface. For more information about configuring a channel on the radio interface of the Cisco 3205 WMIC by using the command-line interface (CLI), see the “Configuring the Radio Channel or Frequency for the C3205 WMIC” section in the Radio Channels and Transmit Frequencies document. To see Dynamic Frequency Selection (DFS) statistics, use the show interface d0 dfs command.

Throughput

The throughput is a minimum of 16 Mbps half-duplex at one mile line-of-sight range for a 20-MHz-wide channel. The range performance is dependent on output power, antenna gain, path loss, and other factors.

The following are range performance estimations:

•6 Mbps at 10 kilometers (6 miles) at 30 dBm equivalent isotropically radiated power (EIRP)

•1 Mbps at 30 kilometers (18 miles) at 30 dBm EIRP

3200 specifications

Cisco Systems 3200 Series routers are designed to deliver high-performance, reliable networking solutions for enterprise and service provider environments. They are part of Cisco's extensive portfolio that addresses the challenges of modern networking, particularly in connecting remote offices and branch locations efficiently and securely.

One of the standout features of the Cisco 3200 Series is its scalability. The routers support a variety of modular interfaces, allowing organizations to tailor their network infrastructure according to specific needs. This modularity ensures that as businesses grow and their networking requirements evolve, the Cisco 3200 can adapt without necessitating a complete overhaul of existing hardware.

Security is another critical characteristic of the Cisco 3200 routers. They incorporate robust security features such as integrated firewall capabilities, advanced encryption standards, and Virtual Private Network (VPN) support. This ensures that sensitive data transmitted over the network is protected from potential threats, making them ideal for businesses that prioritize security, especially in regulated industries.

Performance-wise, the Cisco 3200 is equipped with advanced processing capabilities, enabling it to handle high data throughput even in demanding environments. This performance is bolstered by the use of Cisco's proprietary technologies, such as Quality of Service (QoS) and traffic shaping, which allow the prioritization of critical applications to ensure seamless connectivity.

The router series also benefits from Cisco's extensive software ecosystem, which includes Cisco IOS (Internetwork Operating System). IOS provides a familiar interface for network administrators, alongside a wealth of features for configuration and management. Furthermore, the Cisco 3200 Series is designed to integrate with Cisco's Application Policy Infrastructure Controller (APIC) and Software-Defined Networking (SDN) solutions, offering enhanced flexibility in managing network resources.

Connectivity options for the Cisco 3200 Series are extensive, offering support for various WAN technologies, including MPLS, LTE, and broadband internet. This versatility enables organizations to choose the best connectivity solutions according to their geographic and operational requirements.

Finally, the Cisco 3200 Series routers are built with reliability in mind. They are designed for high availability and redundancy, ensuring that network services remain uninterrupted in the event of hardware failures or maintenance activities.

In conclusion, Cisco Systems 3200 routers represent a comprehensive networking solution, combining scalability, security, performance, and reliability, making them a preferred choice for organizations looking to enhance their networking infrastructure in a dynamic digital landscape.
