Artikelnr: RAP-155
Hastighet: 450Mbps
Typ: Access point

With unmatched deployment flexibility, the RAP-155 series can operate in Aruba Instant™ mode controlled by the AirWave™ management platform or in controller-managed mode where all network services are centralized by Aruba Mobility Controllers.
In Aruba Instant mode, traffic is locally bridged but it still provides the flexibility of establishing secure IPsec VPN tunnels back to Mobility Controllers.
The RAP-155 series offers a wide range of enterprise-class features, including role-based network access and policy-based forwarding.
At locations that require greater coverage, the RAP-155 can join an Aruba Instant WLAN cluster. Simply install additional RAP-155s or any Aruba Instant AP and the entire cluster is managed as one. If one Aruba Instant AP fails, another AP automatically takes over with no disruption.
With a wireless data rate up to 450 Mbps, the dual-radio RAP-155 has five Ethernet ports (one uplink and four local) and a USB port to connect to 3G and 4G networks. Optionally, the RAP-155 can provide power over Ethernet (PoE) on its two local ports for IP phones and other devices.
When operating in Aruba Instant mode, the cloud-based Aruba Activate™ service dramatically reduces RAP deployment time by performing zero-touch provisioning and inventory management.
With Aruba Activate, RAPs are factory-shipped to remote deployment sites and obtain their configurations automatically when powered up.

Advanced Features
  • ClientMatch™ technology eliminates sticky clients by continuously gathering session performance metrics and utilizing this data to steer mobile devices to the best AP and radio, even as users roam and RF conditions change.
  • Adaptive Radio Management™ (ARM) technology automatically assigns channel and power settings, provides airtime fairness, auto-corrects Wi-Fi coverage holes, and ensures that APs stay clear of all sources of RF interference.
  • Fully integrated spectrum analyzer remotely scans the 2.4-GHz and 5-GHz radio bands to identify Wi-Fi and non-Wi-Fi sources of RF interference.
  • Zero-touch provisioning as well as inventory management with the cloud-based Aruba Activate service.
  • Security:
    • With an OpenDNS service subscription, Aruba Instant delivers integrated web filtering, malware and botnet protection to every device connected to the WLAN
    • Integrated Trusted Platform Module (TPM) for secure storage of credentials and keys
    • SecureJack-capable for secure tunneling of wired Ethernet traffic
    • VPN configuration functionality enables the Instant AP to create a single VPN tunnel to an Aruba Mobility Controller in the data center. The Mobility Controller acts solely as a VPN end-point and does not supply the Instant AP with any configuration.
