    Introduction to the Access Point The Cisco Aironet 1550 Series Outdoor Mesh Access Point (hereafter called the access point or AP) is a ruggedized outdoor access point designed for service in mesh networks. The 1550 series leverages 802.11n technology with integrated radio and internal/external antennas. The 1550 outdoor platform consists of Multiple Input Multiple Output (MIMO) WLAN radios and integrated spectrum intelligence (Clean Air).

    Note combination of the amplification of the signal and the antenna gain. The access point has been designed to operate with the Cisco provided antennas. Integrated Antenna Option The 1552C and 1552I models use the Integrated Low Profile Dual-Band 2.4/5 GHz Dipole Antenna Array.

  • Page 20

    The low profile integrated antennas are attached to the bottom of a Cisco access point. The 1552C comes with the option of a C-bracket for strand mounting. The 1552C mesh access point chassis mounting brackets and low profile antenna all fit within the 30 cm vertical right-of-way for cable strand-mounted equipment.

    The selection of the antenna is determined in the configuration of the product. Depending on the 1552 models selected, the antennas can be mounted on a pole and/or cable strand mounted. Refer to the Cisco Aironet 1550 Outdoor Mesh Access Point Hardware Installation Guide for detailed information on mounting the antennas.

    Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023 The Ethernet cable must be a shielded outdoor rated Category 5e (CAT5e) or better cable. The access point senses the Ethernet and power signals and automatically switches internal circuitry to match the cable connections.

    For detailed installation information about the fiber option, see the Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide. Configuration information can be found in the controller configuration guide of the controller you are using.

  • Page 26: Wireless Backhaul

    When the access point does not have a wired Ethernet connection to the controller (through a switch), the radio role is called a MAP. The MAPs have a wireless connection (through the backhaul interface) to other MAPs and finally to a RAP which has an Ethernet connection through a switch to the controller.

  • Page 27

    Figure 14 Access Point Point-to-Point Bridging Example (5 GHz) Point-to-Multipoint Bridging The access points can be used as a RAP to connect multiple remote MAPs with their associated wired networks. By default this capability is turned-off for all access points. To support Ethernet bridging, you must enable bridging on the controller for each access point.

  • Page 28

    Point-to-Multipoint Mesh Network The access point is typically deployed in a mesh network configuration. In a typical mesh deployment, one or more RAPs have a wired network connection through a switch to a controller. Other remote MAPs without wired network connections use the backhaul feature to optimally link to a RAP that is connected to the wired network.

  • Page 30: Site Surveys, Avoiding Damage To Radios In A Testing Environment

    Site Surveys Cisco recommends that you perform a site survey before installing the equipment. A site survey reveals problems that can be resolved before the network is operational. Because 802.11a/b/g/n operates in an unlicensed spectrum, there may be sources of interference from other 802.11a wireless devices (especially in multi-tenant buildings) that could degrade your 802.11 signals.

    To avoid receiver damage and PER degradation, you can use one of the following techniques: • Separate the omnidirectional antennas by at least 2 ft (0.6 m) to avoid receiver damage or by at least 25 ft (7.6 m) to avoid PER degradation. •...
