An Introduction to

Our Mission
Providing wireless service today is complex and
needlessly expensive
2.5B people don’t have
access to telephone services
RangeNetworks2
Governments and first
responders need easy to
deploy systems
The Industry Is Ripe For Change
Consumers
– Usage skyrocketing: mobile subs 3x landlines and mobile traffic 10% of Internet
traffic.(1)
Carriers
– Regulatory and competitive pressures drive need for reduced costs in core-
markets.
– Saturation in core-markets creates desire to expand in developing markets.
RangeNetworks

– Saturation in core-markets creates desire to expand in developing markets.
– Carriers have accepted the need to move to all IP architecture.
Suppliers
– There has been little innovation from infrastructure providers (Alcatel,
Ericsson, etc.)
– Infrastructure providers have too much momentum in their legacy
architectures
– Limited investment in cellular infrastructure startups in past five years.
OpenBTS: Open Source Software
• Open source allows transparency and drives low cost
• Simplify RAN & Network into commodity HW + open source software
– Open, Linux-based platform allows rapid innovation, low cost
– Over 40,000 OpenBTS downloads to date
– Use powerful but inexpensive Software Defined Radios (700Mhz – 2.4Ghz)
• 5 different SDR’s supported
• Great platform for students and researchers
RangeNetworks
• Great platform for students and researchers
– Communications System Design- protocols
– Digital Signal Processing – modulation, error correction
– Even hardware design files are Open-Source
– Modifications for research
• Enables innovation
GSM – Traditional Architecture
RangeNetworks
• HLR - Home Location Register
• AuC - Authentication Center
• MSC - Mobile Switching Center
• VLR - Visitor Location Register
• GMSC - Gateway Mobile Switching Center
• BSC - Base Station Controller
• BTS - Base Transceiver Station
• SGSN - Serving GPRS Support Node
• GGSN - Gateway GPRS Support Node
• OpenBTS collapses GSM/3G
architecture into a single platform
• Leverages 3GPP standards: standard
handsets & interconnect
• Leverages open standards: Linux,
SQL, Asterisk
• Software Defined Radio for RF
GSM – OpenBTS Architecture
RangeNetworks
• Software Defined Radio for RF
Applications & Current Deployments
• Laboratories, universities, & testers
• Rural cellular and WLL services
• Private networks in remote
geographies:
– Maritime
– Mining
– Remote construction
Afghanistan Indonesia
Antarctica Mexico
Argentina Mozambique

• UC Berkeley research• Published in MIT Tech Review
• Mostly local calls and texts• Operates even when backhaul drops
• 900 Mhz, 10w, 2 ARFCN

RangeNetworks
• < 80w power needed
• Villagers pay; school benefits
Simple Deployment: Range RapidCell
RangeNetworks
Serves 400 subs over 2km; draws only 35W power Solar-powered site fits in a station wagon!
Example Installation - Macquarie Island (Antarctica)
• Pilot site for Australian Antarctic Division.
• Closed successful one-year trial in
September 2012, now planning network
expansion.
• Self-contained network based on pre-
(c) Range Networks, Proprietary Information for ICLCT, Dar es Salaam, Oct 24-24, 2012
RangeNetworks
• Self-contained network based on pre-
existing VoIP installation; local calls are
independent of VSAT link
• Saved VSAT Bandwidth
• No longer out of service due to solar activity
affecting polar regions satellite service
Example Installation – Search and Rescue in Iceland
• Broadcast SMS sent – “Help is on the way”
• Drive or fly around the area
• As a plane or truck moves, note the length
of time that a signal from the mobile phone
takes to reach the unit (timing advance)
