4. CrowdCell: Breaking Small Cell’s deployment paradigm
CrowdCell aims to enhance 4G coverage & capacity
through massive deployment of new low cost Small Cells
WHAT IS IT?
• Backhaul provided by 4G macro network
• Radiating VF spectrum TDD 2.6 (Band 38)
• Always on or nomadic, enabled by a central Controller
• Acting as dynamic small cells for customers at the outer
edges of the macro network
BENEFITS
• Cheap and quick deployment – not requiring changes on the
macro network
• Expanding and/or improving indoor coverage and performance
• Better use of limited macro resources
6. Indoor CrowdCell: Key Specifications
• Form Factor: Weight (< 1.5Kg) & Dimensions
(< 3.0L)
• eNodeB output power: 2x250mW –
2x400mW range
• Power Consumption: < 25W
• Access (eNodeB): Band 38 (2600 TDD)
• Backhaul (UE Relay): Band 20 (800 FDD) /
Band 3 (1800 FDD)
• High Capability Backhaul UE
Prototypes Commercial Concepts
7. Field trial results
• Reaching customers not covered by the macro network
• Throughput improvement coming from signal improvement and higher performance CPE (Customer
Premises Equipment)
