Wi-Fi 7 is a game-changing advancement for Wi-Fi networks, and Grandstream has gone all out to take advantage of its capabilities. With the GWN7670 series of wireless access points, Grandstream offers the performance, flexibility, and reliability that modern wireless networks demand.
In this article, we review these extraordinary devices, highlighting the most recent additions, the GWN7670WM and GWN7670LR, and underscoring the most noteworthy features and functions they offer to businesses of all types seeking to deploy robust and reliable wireless networks.
A few months back, we examined Grandstream’s first Wi-Fi 7 device, the GWN7670 wireless access point (WAP). We saw how Grandstream took early advantage of the Wi-Fi 7 standard, ensuring that businesses could get a head start on deploying the newest available standards in wireless technology. At the time, IEEE 802.11be-2024—the official standard for Wi-Fi 7—had not yet been issued; it was officially published in July, 2025.
We then took a closer look at the next device in the series, the GWN7672, a tri-band Wi-Fi 7 access point that takes advantage of more of what the new standard has to offer, including the new 6 GHz frequency band.
Now, Grandstream has added the GWN7670LR (outdoor long-range) and GWN7670WM (indoor wall-mountable) devices to its Wi-Fi 7-certified WAP lineup.
Features of the Wi-Fi 7 indoor access points
All three indoor models offer the high-density, high-bandwidth capabilities of Wi-Fi 7, with 2x2:2 MIMO antenna arrangements, support for the latest PoE standards, and Bluetooth capabilities, all with a range of up to 175 meters (570 feet). All devices have an embedded controller that can control up to 50 registered WAPs and are compatible with Grandstream’s GDMS Cloud and GWN Manager.
Noteworthy Wi-Fi 7 features supported by the indoor devices include the following:
- Multi-RU (MRU): This technology, unique to Wi-Fi 7, allows a wireless client to leverage multiple resource units (RUs), which are portions of a Wi-Fi channel that can be assigned to a device for transmitting or receiving. Using multiple non-contiguous RUs yields improved spectrum utilization and throughput.
- Preamble puncturing: This feature, introduced in Wi-Fi 6E and enhanced in Wi-Fi 7, allows devices to use fragmented or partially available parts of the spectrum instead of requiring a completely clean, wide channel. Channels can be metaphorically “punctured,” which means that any parts that contain interference can be ignored while still using the rest of the channel width.
- Multi-Link Operation (MLO): Wi-Fi 7 clients can use multiple bands simultaneously instead of committing to only one band, improving speed, latency, and resilience.
Quick review of the GWN7670 and GWN7672 APs
The GWN7670 is a Wi-Fi 7 access point (AP) that delivers fast, reliable performance with dual-band 2x2:2 MIMO support. The device supports downlink and uplink OFDMA, a multiple-access technology that substantially improves the efficiency of sharing Wi-Fi channels among multiple devices.
The GWN7672 can be thought of as the flagship of the lineup. Similar in appearance to the GWN7670, it possesses Wi-Fi 7 capabilities beyond those offered by the other two models. These features include:
- Support for tri-band operation in the 2.4 GHz, 5 GHz, and 6 GHz bands
- Maximum wireless throughput of 11 Gbps
- Support for up to 48 SSIDs
- Up to 384 concurrently connected wireless clients
- Two 5 Gbps RJ-45 Ethernet ports
- Support for a wider range of channel bandwidths
- Seven internal antennas: two for each band plus one auxiliary antenna for Bluetooth and IoT scanning
The GWN7672 embodies the best of Wi-Fi 7, all within a compact and versatile wall- or ceiling-mountable package.
The GWN7672WM wall-mountable AP
The GWN7670WM is similar to the GWN7670 model, providing comparable features. Both models have the same dual-band capabilities and the same 3.6 Gbps aggregate wireless bandwidth. They support up to 32 SSIDs and 256 clients and feature the same channel bandwidths and antenna allocation (two antennas for 2.4 GHz and three for 5 GHz).
In contrast, the GWN7670WM model does not come in the conventional UFO-shaped ceiling-mountable casing but in a more rectangular wall-mountable shell that is paintable to make it blend in with various decoration styles. It can be installed flush with the wall or embedded within it, much like a power outlet or light switch, making it even more inconspicuous. It has a single LAN port for power (PoE) and support for 2.5 Gbps speeds.
Simply put, the GWN7670WM offers additional deployment options, making it a perfect fit for environments where aesthetics and interior design are a priority.
What about outdoors? Meet the GWN7670LR
For outdoor or long-range scenarios, there’s the GWN7670LR, a dual-band Wi-Fi 7 access point designed for weather-exposed deployments. It offers IP66-level weatherproofing, long-range coverage of up to 350 meters (1,148 feet), 2×2:2 MIMO, BLE 5.3, and flexible uplink options with 1× 2.5G RJ-45 (PoE+) plus 1× 2.5G SFP. Like the indoor models, it includes the embedded controller (up to 50 APs) and supports GDMS Cloud and GWN Manager.

Use cases
This series offers the perfect mix of characteristics to provide what enterprises need from their WAPs:
- The GWN7672 handles heavy lifting in high-density areas.
- The GWN7670 fills in general coverage needs at a lower cost.
- The GWN7670WM gives localized Wi-Fi in rooms and offices where inconspicuousness is paramount.
- The GWN7670LR provides outdoor and long-range coverage for large spaces.
To fully appreciate the flexibility and diversity of deployment of these devices, consider the example of a multi-floor enterprise office building with a few hundred employees. The environment includes large open-concept workspaces, conference rooms of various sizes, and a large multi-purpose hall capable of hosting several hundred people for a variety of events and activities. Certain areas feature carefully designed aesthetics, where appearance is just as important as functionality.
In such an environment:
- The GWN7672 can be deployed in large open indoor spaces, open-plan offices, conference rooms, and the large hall to provide high-capacity Wi-Fi with 6 GHz support for modern devices while still handling the 2.4 and 5 GHz bands for older devices. The WAP supports dual 5 Gbps Ethernet links for high-capacity backhaul and redundancy.
- The GWN7670 can be placed in standard office areas, hallways, and shared workspaces, where traffic is moderate and demand is more conventional. These devices offer balanced performance at a lower cost and can be installed on the wall or ceiling for good range and coverage.
- The GWN7670WM can be installed in executive offices, reception rooms, or executive-level conference rooms. It is perfect for any location where the décor requires a more unobtrusive installation.
- The GWN7670LR can be used to connect different floors as well as the warehouse, loading docks, and parking areas.
All the devices can be managed centrally by an embedded controller in one of the WAPs, a deployed GDMS cloud service, or the Grandstream GWN Manager. This way, enterprises can enjoy optimized performance, cost savings, and flexible form factors in one Wi-Fi-7-enabled wireless network design.
Conclusion
Modern businesses must continually adapt to meet the needs of both customers and employees. Incorporating technologies such as Wi-Fi 7 is a clear step in that direction. Employing access points such as these allows businesses to future-proof their networks, ensuring reliable, high-performance connectivity that delivers lasting value at a cost-effective price.
