Cisco® Aironet® 1240G Series Access Points provide single-band 802.11g wireless connectivity for challenging RF environments such as factories, warehouses, and large retail establishments (Figure 1). Connectorized antennas, a rugged metal enclosure, and a broad operating temperature range offer extended range and coverage versatility. The Cisco Aironet 1240G Series provides local as well as inline power, including support for IEEE 802.3af Power over Ethernet (PoE).

Figure 1. Cisco Aironet 1240G Access Point

The Cisco Aironet 1240G Series is a component of the Cisco Unified Wireless Network, a comprehensive solution that delivers an integrated, end-to-end wired and wireless network. Using the radio and network management features of the Cisco Unified Wireless Network for simplified deployment, the Cisco Aironet 1240G Series extends the security, scalability, reliability, ease of deployment, and manageability available in wired networks to the wireless LAN (WLAN).
The Cisco Aironet 1240G Series is available in two versions: unified or autonomous. Unified access points operate with the Lightweight Access Point Protocol (LWAPP) and work in conjunction with Cisco wireless LAN controllers and the Cisco Wireless Control System (WCS). When configured with LWAPP, the Cisco Aironet 1240G Series can automatically detect the best-available Cisco wireless LAN controller and download appropriate policies and configuration information with no manual intervention. Autonomous access points are based on Cisco IOS ® Software and can optionally operate with the CiscoWorks Wireless LAN Solution Engine (WLSE). Autonomous access points, along with the CiscoWorks WLSE, deliver a core set of features and can be field-upgraded to take full advantage of the benefits of the Cisco Unified Wireless Network as requirements evolve.

Applications

Designed for rugged environments and installations that require antenna versatility, the Cisco Aironet 1240G Series features antenna connectors for extended range or coverage versatility and more flexible installation options. Manufacturing applications, for example, can place WLANs in hazardous locations and remotely place antennas in those locations while securing the Cisco Aironet 1240G Series Access Points.
The metal housing and industrial-grade components of the Cisco Aironet 1240G Series provide the ruggedness and extended operating temperature range required in factories, warehouses, "big box" retail environments, and similar facilities. High transmit power, receive sensitivity, and delay spread for 2.4-GHz radios provide the long range and large coverage area consistent with these applications. Access points can be placed above ceilings or suspended ceilings, allowing antennas to be discreetly placed below drop ceilings. The UL 2043 rating of the Cisco Aironet 1240G Series allows for placement of the access points above ceilings in plenum areas regulated by municipal fire codes. Public access applications such as large hotel buildings can also present a challenging RF environment; the antenna versatility of the Cisco Aironet 1240G Series, together with industry-leading range and coverage, provides reliable performance for the most demanding environments.
