Checked specifications for Grandstream
3 of 3 Grandstream models have been checked against the manufacturer's datasheet or spec page, or against a retailer listing that quotes it. Streams and peak antenna gain below are the manufacturer's published figures; the planner derives transmit power, throughput and client capacity from them. Last review: 9 October 2026.
| Model | Wi-Fi | Streams 2.4 / 5 / 6 GHz | Peak gain dBi 2.4 / 5 / 6 GHz | Source |
|---|---|---|---|---|
| GWN7615 | Wi-Fi 5 | 3 / 3 / — | 3 / 3 / — | Retailer listing quoting the vendor |
| GWN7660 | Wi-Fi 6 | 2 / 2 / — | 3 / 3 / — | Retailer listing quoting the vendor |
| GWN7664 | Wi-Fi 6 | 4 / 4 / — | 4 / 4 / — | Retailer listing quoting the vendor |
Among the checked models the widest 5 GHz radio is 4 spatial streams (GWN7664). More streams raise the data rate a single client can reach and the capacity of the access point, but they do not extend range by themselves; antenna gain and transmit power set the range.
How to plan a Grandstream network
- Upload a PNG, JPG or WebP floor plan and set its scale.
- Choose the design band and a minimum RSSI. About -65 dBm suits voice and video.
- Draw glass, drywall, brick, concrete and lift-core walls.
- Select Grandstream and calculate. The tool recommends a model and quantity from your floor size, clients and throughput.
- Move access points on the map, then export the AP list or a report.
Questions about Grandstream planning
Does the planner support Grandstream access points?
Yes. It includes 3 Grandstream models (1 Wi-Fi 5, 2 Wi-Fi 6). Pick the brand and let the tool recommend a model and quantity, or enter your own model mix.
Can I plan 6 GHz coverage with Grandstream?
None of the Grandstream models in this planner support 6 GHz, so plan on 2.4 GHz or 5 GHz.
Where do the Grandstream specs in the planner come from?
3 of 3 Grandstream models are checked against the vendor datasheet or spec page; the rest use Grandstream's family specification and are marked est. in the planner. The planner turns Wi-Fi generation, spatial streams and antenna gain into transmit power, throughput and client capacity for the band and channel width you choose. Check the current datasheet before you buy.
How accurate is a Grandstream Wi-Fi heatmap forecast?
It is a predictive planning estimate based on distance, wall attenuation, band and the published datasheet specifications of the Grandstream model you choose. Confirm it with an on-site survey before buying or installing Grandstream equipment.
