Cascaded Star Wireless Network Architecture for Scalable Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In areas with limited internet infrastructure, such as India, there is a challenge in providing scalable and cost-effective wireless network solutions that can deliver Video on Demand (VoD) and internet services efficiently, especially due to limited de-license spectrum in frequency bands like 2.4 GHz ISM and 5 GHz U-NII bands.
Innovation Solution
A wireless network architecture with a cascaded star topology is deployed, utilizing 2.4 GHz and 5 GHz industrial, scientific, and medical (ISM) radio bands, featuring devices that can operate as multiple roles (router, base station, gateway, relay, or customer station) and organized into hierarchical units of cells, nodes, and devices, allowing for flexible and scalable network configuration.

1Area of stationary object
If a wireless network architecture is deployed in areas with limited internet infrastructure using limited de-license spectrum, then network coverage and service delivery are improved, but network capacity and scalability are constrained
Solution Approach 1:
The network is divided into multiple hierarchical levels (macro cells, micro cells, pico cells, femto cells) that can be deployed independently. Each cell type serves a specific coverage area and capacity requirement, allowing the network to scale from small localized areas to large regional coverage while efficiently utilizing limited spectrum resources at each level.
Solution Approach 2:
Smaller cell types are nested within larger cell structures. Micro cells are deployed within macro cell coverage areas, pico cells within micro cell areas, and femto cells within pico cell areas. This nested architecture allows multiple layers of network infrastructure to coexist and share spectrum resources, thereby increasing overall network capacity without requiring additional geographic space.
2Adaptability or versatility
If multiple device types are used to provide diverse network functions, then network functionality and versatility are improved, but device complexity and manufacturing costs increase
Solution Approach 1:
A single base station device is designed to perform multiple functions across different hierarchical levels. The same device type can function as a macro base station, micro base station, pico base station, or femto base station depending on configuration and deployment context. This multi-functionality reduces the need for separate specialized hardware for each cell type, thereby simplifying manufacturing while maintaining network versatility.
Solution Approach 2:
The base station device incorporates dynamic configuration capabilities that allow it to adapt its operating parameters, coverage area, and functional role based on deployment requirements. The device can dynamically adjust its transmission power, frequency allocation, and network protocol implementation to suit different cell types and network conditions, providing versatility without requiring multiple fixed-function device variants.

AI summary
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.
