In contrast with the Netgear Orbi, Velop is a mesh-system: when you have more than two nodes, they communicate with each other. With the Orbi, communication is always via a central point. The towers are as closed as oysters and cannot be opened without being destructive. However, as we know from their specifications, the Velop-nodes are based on a Qualcomm IPQ4019 processor with four cores. This chip operates at only 700 MHz and is not exactly fast. In the nodes you do not only find WiFi, but also Bluetooth-technique – as mentioned before, this is necessary for the installation.
A noteworthy detail is that the nodes are also equipped with Zigbee. This is not yet used, but the manufacturer presumably has a plan for it in the future. Standard a single 5GHz radio is used for the connection between the nodes; a second 5 GHz band can be added. Those two are delivered by a Qualcomm QCA9886. The choice for this results in the Velop nodes being a lot more compact than the big Netgear Orbi nodes.
From the IPQ4019 there is also a single 2.4 GHz band available with a bandwidth of 400 Mbit/s and two times 867 Mbit/s available. You could potentially use a gigabit cable to connect the nodes, although this is not yet supported by the installation procedure on the smartphone.
