UE RELAY

AN eNB TO ITS USERS AND A UE TO THE DONOR eNB

Dense Air Small Cell unit supports LTE-A (FDD or TDD) and an optional WiFi AP (802.11n concurrent with 802.11ac). It is composed of an eNB for access and a standard high-performance UE relay for wireless backhaul.

Instead of connecting to the EPC via wireline backhaul, the eNB is connected to the UE relay via a cable, and the UE relay is connected via a standard LTE wireless connection to a different cellular cell, known as the Donor eNB effectively.

SMALL CELL ECONOMICS

MAKING SMALL CELL DEPLOYMENT ECONOMIC

Traditional outdoor MNO deployment of LTE Small Cells is generally uneconomic, hence very limited deployment by MNOs. Key issues are Site Rental, Power, Zoning, Construction, CAPEX, and Backhaul. Indoor “DAS-Style” deployment of small cells is equally as uneconomic, with less than 5% of buildings having a DAS, or small cell installation. A key reason why dedicated small cell deployment by individual mobile operates is uneconomic is the limited coverage footprint they provide, which in turn serves limited users and does not justify the CAPEX investment. Dense Air solves this by pooling end users from multiple networks to provide a solid economic basis for massive small cell deployment.

VIRTUALISED SMALL CELLS AS A SERVICE

VIRTUAL INSTANCES SUPPORTING PHYSICAL ENODEBS

Dense Air “virtualizes” it’s small cells. Each real physical eNodeB supports multiple “virtual” instances. A single set of active electronics (eNB) enables Neutral Host network sharing. Each virtual instance of an eNodeB is fully encapsulated with separate address space, separate management and control interfaces. No sharing of any data between virtual instances. Each Virtual eNodeB has it’s own PLMN ID. Dense Air implements an advanced QoS and SLA solution to ensure that each virtual small cell delivers the target capacity.

NETWORK SLICING

Dense Air’s unique virtualised small cell sharing technology is an example of 5G Network Slicing. ‘Slicing’ is used for resource management in a neutral host architecture. Network slices are a set of network functions and resources to run those functions. Separate slices can be assigned to each operator and can map logical and physical resources to ensure quality of service.

STANDARDS COMPLIANT

COMPATIBLE WITH 3GPP STANDARDS

Dense Air’s unique virtualised neutral host small cell is fully compatible with 3GPP standards and interfaces, it is not based on MOCN/MORAN or active RAN sharing. The Dense Air wholesale network broadcasts multiple PLMN ID’s to end users, providing a separate PLMN ID for each MNO. The small cells also support MVNOs providing both 4G & 5G technologies.

DENSEWARE

INTELLIGENT DEPLOYMENT OF NEUTRAL HOST SMALL CELLS

DenseWare is a toolkit of technologies that allows pinpoint deployment of small cells into locations that solve coverage holes or capacity weak spots. Denseware allows customers of the Dense Air service to see where macro cell coverage is poor or cell edge capacity is weak.

The toolkit supports building by building analysis of Denseware collects millions of anonymous network logs from smartphones to create real-time performance knowledge on 4G LTE networks. Big Data analysis techniques crunch this data on a weekly basis to ensure the investment in small cell deployment instantly improves the end user performance and service quality.
