Fig. A. Grandstream Networks’ GWN7630LR outdoor long-range Wi-Fi access point
As an end user in a mobile society, we are ever more reliant on good Wi-Fi connectivity to run our high bandwidth applications and high-client density scenarios indoors or outdoors. We now have outdoor long-range 802.11ac Wave-2 Wi-Fi access points (APs) that are equipped with embedded controllers and that also supports centralized, scalable management system choices, such as cloud hosted/cloud Software-as-a-Service (SaaS) or a premises-based Virtual WLAN (vWLAN) controller. These APs are also equipped with features, networking standards and protocols such as: Multi-User Multiple Input Multiple Output (MU-MIMO) technology, band steering, multiple service set identifiers (SSIDs), dual-2.4GHz/5GHz radio bands, mesh networking, gigabit ethernet ports with PoE/PoE+,802.11ac, 802.11ac Wave 2, 802.11k, 802.11r and 802.11v, air time fairness, captive portal for custom branding experiences, client bridge function, client steering, multicast stream to unicast stream conversion, and beamforming. They also include Wi-Fi and system security features, such as: Digitally signed firmware for anti-hacking secure boot, randomly generated default password, unique security certificate, WEP, WPA/WPA2-PSK and WPA/WPA2 enterprise, ports to connect external antennas, and master controller failover functions for redundancy and backup.
Let us examine how such access points can prove beneficial to an end user’s overall wireless experience. Embedded controller functionality on the AP permits centralized management/monitoring and set-up of other APs and clients, on the wireless network without any additional cost and infrastructure for Wi-Fi controllers. Mesh networking feature provides redundancy and creates wireless radio connections between APs. With the beamforming feature, access points detect the location of clients and direct the antenna beam towards them. The client bridge feature allows the AP to bridge wired clients. Band steering enables the AP to select the least-used radio band. MU-MIMO using multiple antennas, enables transmission and reception of multiple data streams concurrently – multiple spatial streams – for improving network throughput. Converting multicast to unicast streams over the wireless link helps conserve bandwidth for other wireless clients and improves the quality and reliability of video and audio streams. Multiple SSIDs permit multiple wireless segments. Client steering within the same network helps Wi-Fi clients roam to other APs. A custom splash page or captive page – a web page that is displayed to newly connected Wi-Fi users – prompting them for authentication aids in a custom branding experience. Last but not the least, a centralized cloud Wi-Fi management platform enables management and control for unlimited APs across geographic locations using a browser or mobile app, without requiring a Wi-Fi controller on premises.
The ensuing discussion will focus on the Grandstream Networks’ GWN7630LR outdoor long-range 802.11ac Wave-2 4x4:4 Wi-Fi access point (Refer to Fig. A above) and the cloud controller GWN.cloud for Wi-Fi management and monitoring.

Fig. B: Functional testing of Grandstream Networks’ GWN7630LR
We first mounted and connected the GWN7630LR using the provided installation accessories. Microchip Technology PDS-208G/PDS-408G Digital Ceiling PoE switches provided PoE and network connectivity. Patton networks Virtual SmartNode (vSN) as a Virtual Network Function (VNF) Session Border Controller (SBC), delivered SIP registrar services and SIP demarcation from the public SIP trunk/UCaaS provider in the cloud, while preserving interoperability and interconnectivity. Patton Cloud, a single portal network orchestration tool, was used for its provisioning and management.
We opened a browser and logged into the GWN7630LR (selected log in role as master), and the ensuing setup wizard guided us through the basic setup (edited/selected the required values: Country, Time Zone, AP status showed as Master, enable SSID, SSID name, security mode, WPA key mode, WPA encryption type, WPA pre-shared key). Under SSIDs for the previously set up SSID, we edited/selected the required values for Client bridge support, multicast to unicast, enable Voice Enterprise, enable 802.11r, enable 802.11k, enable 802.11v, etc. We then moved to the next item on the menu, listed as access points. There for our APs in the test Wi-Fi network setup. We edited/added/selected the correct values and configurations, starting with the GWN7630LR’s Device name, fixed IP, IPv4 address, IPv4 subnet mask, IPv4 gateway, preferred IPv4 DNS, alternate IPv4 DNS, band Steering, client steering,.2.4GHz/5GHz, mode, channel width, active spatial streams, and radio power. We then saved and applied the settings. We clicked on discover AP, paired AP GWN7630 and configured it with the appropriate values for the parameters listed above.
The GWN7630LR was now a member of the dual-band SSID that we created, and its embedded controller function was used to manage the GWN7630 AP and the Wi-Fi network clients. (Refer to Fig. C & Fig. D).

Over the dual band Wi-Fi network, we tested Microchip Technology's AcuEdge ZLK38AVS2 Front end audio Development Kit connectivity to the cloud-based Amazon Alexa Voice Service (AVS) and SIP registration/connectivity of the Grandstream Networks GXV3370 IP video phone, Grandstream Networks WP820 SIP Wi-Fi phone and Grandstream Networks GRP2614 carrier grade IP phone. We were successful in registering and placing inbound/outbound voice calls with the ITSP’s external SIP trunk/UCaaS platform in the cloud through the Patton networks Virtual SmartNode(vSN) as a Virtual Network Function (VNF) Session Border Controller (SBC). Over the Wi-Fi network, we were able to run applications that required high bandwidth and low latency, such as real-time voice, video calls, streaming media and video-on-demand.
It was now time for us to transfer the GWN7630LR and the GWN7630 APs to the GWN.cloud. For that we clicked on the Transfer network group button, which allowed us to transfer our local configurations to our cloud account. It prompted us to create a network by entering a new network name for the network group and, alternatively, if we clicked on the Transfer AP button, it would have allowed us to select a pre-existing network group and move our APs to it (Refer to screenshot excerpts Fig. G).
