•  Capacity of a macro baseband unit (3 – 12 sectors) distributed inside building using a DAS-like dedicated RF distribution system •  Connects to 3G RNC & LTE EPC just like an eNB, using carrier managed backhaul •  Relies on Macro EMS rather than SON for configuration

•  Commercially available (and announced) systems offer up to 200 sectors of capacity over 100,000 m2 of floor space •  Small cell controller enables ease of deployment and performance – manages mobility inside building, manages interference

using ICIC, provides SON for small cells, removes need for HeNB GW in core, and offers platform for mobile edge computing •  Relies on SON software, rather than macro EMS, for configuration

Looking Ahead - Roadmap for Enterprise Small Cells

17

Technology Benefit LAA LTE 2x Capacity without 2x Spectrum in

Single Operator Small Cell Deployments

MulteFire Neutral host LTE in venues (where business case for single-operator small cells does not work)

Authorized Shared Spectrum

Neutral host LTE in venues Private LTE networks

•  LAA is part of 3GPP R13 and likely to be launched in 2017 to add network capacity •  MulteFire requires standardization in 3GPP or similar organization. Will work in existing 5 GHz spectrum •  ASA (aka CBRS in US) requires regulatory approval, standardization, and spectrum database systems


Small Cells with Baseband at the Edge Essential for Using Unlicensed Spectrum

18

Transmit

Reserve

Assess

Decision to use unlicensed bands must be made in microseconds


DAS & RRH Systems Unsuitable for Unlicensed

19

Baseband Unit will lose opportunities to use unlicensed spectrum

1.  LTE scheduler must either decide to use unlicensed channel after monitoring it for 34 µs, or risk losing channel to Wi-Fi AP

2.  Each centralized baseband cell will overlap with dozens of Wi-Fi APs. If any of these Wi-Fi APs uses the channel, it will back-off

LTE-LAA Baseband Unit connected to multiple remote radio heads. All RRHs use same channel for LAA

Remote Radio Heads (RRHs)

Coverage area of RRH

Remote Radio Head Aggregator

Baseband Unit and connected RRHs will reduce Wi-Fi system capacity

1.  Baseband unit connected to multiple RRHs occupies the channel in a much larger region that it needs to service its subscriber

2.  All Wi-Fi APs that use same channel as LTE cell will find the channel busy and will back-off, reducing Wi-Fi system capacity


SpiderCloud Enterprise Radio Access Network (E-RAN)
