WBUHS101-P-005 v1.0

Market trends - Identity
ƒ “Know your enemy”

ƒ Identification is a crucial first step in defending
the public against potential threats

ƒ Ubiquitous mobile phone ownership
– Up to 96% in USA
– Generally personal devices

ƒ Mobile phone SIM card gives a unique,
electronically readable personal identifier

WBUHS101-P-005 v1.0

Market trends – Mobile surveillance
ƒ Technology is a “moving target”
– Movement from voice to data connectivity
– Machine to Machine communications (M2M)
– Evolving standards GSM to GPRS to 3G to HSPA to LTE
– White-space radio…

WBUHS101-P-005 v1.0

Market trends – Mobile surveillance
ƒ User needs
– Smaller size units
– Fast deployment
– Scalable usage
– Covert operation
– Reduced number of unwanted phones detected

ƒ And finally… within a budget

WBUHS101-P-005 v1.0

Market Trends – Consumer products driving innovation
ƒ Example – femtocells are compact cellular base-stations
in your home

ƒ High performance –when compared to a conventional base station, still
has a similar processing requirement
ƒ Extremely compact – requires highly integrated solution
ƒ Growth opportunity – mass market consumer product
ƒ Investment - new architectures and technologies

WBUHS101-P-005 v1.0

Technology Trends – Software Defined Radio
ƒ picoChip baseband processing chip
ƒ All baseband processing requirements from
digital samples to and from RF through to
network interfacing is integrated enabling an
extremely low BOM cost
ƒ For example, PC312 consists of a 3GPP Node B
PHY, ARM11 processor, cryptographic engine,
high speed accelerators and peripherals
ƒ Software defined radio architecture allows
manufacturers to develop whilst specifications
are maturing and update design using software
patches

WBUHS101-P-005 v1.0

Market trends – Consumer technologies taken into other markets
ƒ Iridium is the only truly global telecoms network
– Low Earth Orbit satellites, with low delay and no
orientation of the handset antenna

ƒ Challenge is to create a broadband data terminal
ƒ Solution
– Set of 7 antennas in ground terminal equipment to
track satellites moving at 8km/s whilst also adapting to
movement of the platform
– Compensation for the small received signal and the
Doppler shift caused by the very fast movement of the
satellites
– Platform based approach to design, using Software
Defined Radio architecture
– Consumer technology taken from femto-cell products

ƒ Cambridge Consultants responsible for full system
design and implementation, from concept to product

WBUHS101-P-005 v1.0

Small cellular base station - concept

ƒ Commercial components and technology to
implement a “tiny base-station”
– Baseband processing from picoChip
– Programmable radio receiver from Lime
microsystems
ƒ Cellular communication physical layer
– Reference design for GSM / GPRS
– Software upgrade to 3G
– Functions as base station and network sniffer,
for detection of background cellular conditions

Small cellular base station – uses
ƒ Covert
– Low power, can run from battery
– Small size
ƒ Mobile phone identification
– IMSI grabbing
ƒ Ad-hoc communications
– Private local network for independent team working when infrastructure
networks are not an option
