OpenBTS: A multiprotocol IP wireless platform
• Software implementation Layers 1-7- No ASICS or special hardware- High performance DSP in software- Virtualization = flexibility, repurposing, multiple protocols- Platform API’s encourage innovation (Layers 1-7)- All-IP simplified network services (voice, messaging, etc.)
• 2G, 3G, 4G (and IoT protocols)- Additional capacity ::= additional CPU cores (i.e. ARM -> INTEL)
• Plays from picocells to macrocells

Why is a Wireless SW Platform a Big Deal?
• Wireless/IoT will be HUGE• Fragmentation
- Spectrum: many new bands, shared, unlicensed & licensed- Devices: Smart cars, Alarms, Security – very different needs, ARPU
Some are mobile – signalling storms are coming
• Software-defined mobile supports Frequency & Protocol agility• Market expansion from 5B to 7B people
- Order of magnitude reduction in Capex/Opex- Order of magnitude reduction in Complexity
• Open platforms invite new capital & innovation• Open platforms ease operator integration & services

Unique Enterprise Platform Value
• Identity: BYOD enabled- In-Enterprise: mobile calls have business
number (PBX) origin- Out-of-Enterprise: mobile calls have
personal number origin- Authentication via upstream HLR
• Native Dialer- No OTT app installed/used
• Location- Triangulated mobile location enables FMC,
tracking, other functions- Available via Publish/Subscribe service &
platform API’s
• Messaging & Presence- SMS enabled on all mobile devices, can be
integrated with LAN messaging
• Apps- Easily integrated via platform API’s & Docker
• Privacy- Mobile device incorporated into Enterprise network- HIPPA, etc.
