Abstract

Technologies directed to a wireless network with a cascaded star topology with multiple devices at multiples nodes are described. In one wireless network, multiple devices are manufactured as a common device type and deployed at different nodes of the wireless network. The devices are configured to operate as a base station (BS) role, a gateway (GW) role, a relay (RL) role, or a customer station (STA) role. The nodes can be a base station node (BSN), a relay node (RLN), or a customer premises equipment (CPE) node. One node can be a first-tier hub of the cascaded star topology and another node can be a second-tier hub of the cascaded star topology.

Dependent claims

A wireless network comprising:

a router device;
a base station node comprising a first network switch, a base station device, a first gateway device, and a first storage device, wherein the base station device, the first gateway device, and the first storage device are coupled to the first network switch, wherein the first network switch is coupled to the router device over a wired connection, wherein the router device, the base station device, the first gateway device, and the first storage device each comprises identical hardware;
a relay node comprising a second network switch, a relay device, a second gateway device, and a second storage device, wherein the relay device, the second gateway device, and the second storage device are coupled to the second network switch, wherein the relay device, the second gateway device, and second storage device each comprises the identical hardware;
and
a first customer premises equipment (CPE) node comprising a customer station (STA) device and one or more endpoint devices, wherein the customer STA device comprises the identical hardware, wherein:
the base station node (i) connects to an Internet Service Provider (ISP) ingress via the router device, (ii) provides a first wireless service to the relay node, and (iii) provides a second wireless service to a second CPE node using the first gateway device;
the relay node (i) connects to the base station node via the first wireless service using the relay device and (ii) provides a third wireless service to the first CPE node using the second gateway device;
the customer STA device provides access point functionality to the one or more endpoint devices;
and
the base station node, the relay node, the first CPE node, and the second CPE node are organized logically in a cascaded star topology in which:
(i) the base station node is a first-tier hub with respect to the relay node and the second CPE node;
and (ii) the relay node is a second-tier hub with respect to the first CPE node.
