Richtantenne MIMO Lancom Systems AirLancer IN-Q180+ — 2,4–5,9 GHz, 5 dBi, RP-SMA, dual-polarisatie

The Lancom Systems AirLancer IN-Q180+ is a directional MIMO ceiling antenna designed for indoor Wi‑Fi deployments across 2.4–5.9 GHz. With a compact form factor (130×130×45 mm) and a 180° radiation pattern, the antenna is intended for installation under suspended ceilings to provide broad, controlled coverage. It supports 4x4 MIMO operation using four RP‑SMA connectors, dual polarization and is optimized for contemporary Wi‑Fi standards including IEEE 802.11ac and 802.11ax. The unit includes RG‑178 cable and a mounting kit for ceiling or wall attachment.

Advantages

The AirLancer IN-Q180+ provides reliable multi‑stream throughput by combining four antenna elements and dual polarization to improve spatial diversity and reduce multipath issues in indoor environments. Its directional 180° beam shapes coverage to focus signal where needed, reducing interference outside the target area. The compact, low‑profile design allows discreet installation under suspended ceilings and the RP‑SMA terminations enable straightforward connection to access points or extension cables. The antenna’s frequency range and gain characteristics support parallel operation on 2.4 GHz and 5 GHz bands for mixed-device environments.

Suitable for

• Wi‑Fi coverage extension in offices, hotels and schools
• Installation on suspended ceilings and low‑profile mounting locations
• 4x4 MIMO access point deployments requiring dual‑band performance
• Controlled directional coverage to limit spill‑over and interference

How to use

Install the antenna under a suspended ceiling or on a wall using the supplied mounting kit, positioning it directly beneath or adjacent to the access point for best results. Connect each RP‑SMA lead to the corresponding antenna port on the access point or via short RP‑SMA extension leads if needed. Orient the antenna so the 180° coverage faces the intended service area. After mechanical installation, verify RF connections and perform site measurements or a site survey to confirm coverage and channel planning. For multi‑AP deployments, coordinate antenna orientation and channel allocation to minimize overlap and co‑channel interference.

Recommendations

Use the AirLancer IN-Q180+ with dual‑radio 4x4 access points designed for 802.11ac/ax to make full use of the antenna’s MIMO capabilities. Place the antenna centrally within the coverage zone under suspended ceilings and avoid obstructive metallic fixtures directly above the antenna to maintain consistent gain and radiation pattern. Perform on‑site testing after installation to adjust orientation and verify signal distribution across both 2.4 GHz and 5 GHz bands.
