The LANCOM OAP-382 Outdoor Access Point
The LANCOM OAP-382 Outdoor Access Point is the right choice for anybody taking high-speed 802.11n wireless LAN to outdoor areas. Its two radio modules make this access point suitable for a wide range of applications: For example, it can operate as a relay station in a link to a backbone while simultaneously providing Internet access for WLAN clients. With its water-jet resistant IP66 housing, integrated heating and cooling, and the sturdy fittings for wall and pole-mounting, the device can be operated wherever the highest standards for stability and robustness apply - be it in the mountains or from rooftop to rooftop in the city. The OAP-382 can be easily and economically mounted up to 50m from the nearest power supply thanks to Power over Ethernet. For longer distances the combined operation of the LANCOM OAP-380 Fiber Kit and the power supply kit LANCOM OAP-380 PSU is recommended.

The LANCOM OAP-382 can be networked via Ethernet or fiber optics. The externally accessible SFP slot provides a variety of options for implementing the fiber-optic connection. The device also offers versatility in the choice of power supply: Depending on the local situation, the LANCOM 382-OAP can be powered either by the supplied Gigabit High Power PoE injector or via an optionally available 48V cable.
LANCOM ensures the highest security standards as it supports a comprehensive range of encryption and authentication mechanisms, including 802.11i, 802.1x, and WPA2. With the aid of Multi-SSID and protocol filters, up to 8 different user groups can each be assigned with different levels of security. VLAN technology, matured quality-of-service functions and bandwidth limitation enable the reliable transmission of video and multimedia data.
A management system is vital outdoors where conditions are difficult, for example when it is hard to see the LEDs on an access point mounted on a tall mast. The free LCMS LANCOM Management System allows the monitoring of all device functions and provides an overview of the entire network. For example, it is possible to check whether the access points are transmitting and, if so, on which channels, how much data each one is sending, which clients are logged in and where, what encryption method is active, and a whole lot more. The LANCOM Management System also helps you to optimize performance over wireless bridges. Additionally, the LANCOM OAP-382 supports TACACS+. Using the AAA protocol ("authentication, authorization, accounting") it is possible to track all activities relating to the configuration of the access point.

Possible applications are roaming without changing the IP address and compounding SSIDs without using VLANs.
IEEE 802.11n Features
- MMO:: MIMO technology is a technique which uses multiple transmitters to deliver multiple data streams via different spatial channels. LANCOM uses a 3 x 3 MIMO Configuration where 2 data streams are spread over 3 transmitters. Depending on the existing RF conditions the throughput is doubled with MIMO technology
- 40 MHz Channels: Two adjacent 20 MHz channels are combined to create a single 40 MHz channel. Depending on the existing RF Conditions channel bonding doubles the throughput.
- 20/40MHz Coexistence Mechanisms in the 2.4GHz Band: :Support of coexisting accesspoints with 20 and 40MHz channels in 2.4GHz band.
- MAC Aggregation and Block Acknowledgement: MAC Aggregation increase the 802.11 MAC efficiency by combining MAC data frames and sending it out with a single header. The receiver
acknowledges the combined MAC frame with a Block Acknowledgement. Depending on existing RF conditions, this technique improves throughput by up to 20%.
- Maximal Ratio Combining (MRC): Maximal Ratio Combining (MRC) enables the receiver (access point), in combination with multiple antennas, to optimally combine MIMO signals
to improve the client reception at long-range.
- Short Guard Interval: The guard interval is the time between OFDM symbols in the air. 802.11n gives the option for a shorter 400 nsec guard interval compared to the legacy 800 nsec guard interval. Under ideal RF conditions this increases the throughput by upto 10%
