Mobile Horizons - 4G

1. Beyond 4G with Pi in sky!
Kamran Kordi

2. 4G: An update
• 4G roll out will receive a major boost after the spectrum auction
– 800 Mhz and 2.6 Ghz
– Some carriers have indicated that the new 4G would not affect tariffs
– The average download rate of around 20 Mb/s proven to be achievable
• LTE Advanced has already been kicked off in the 3GPP
– NTTDoCoMo of Japan has already shown and initial live demonstrator
• 1 Gb/s downlink and 200 Mb/s while the terminal was moving at a speed of 10 km/h
• Software defined radio is a technology reality
– It is becoming a mature alternative to hard wired radio
LTE-Advanced requires a cycle of 10 years for consensus and roll out

3. TV white Space
• Frequencies allocated to broadcasting not used
locally (white space)
• Frequency range (470 Mhz to 790 Mhz)
– The key idea is to search for unused gaps in the
available frequencies/locality and reuse them
– No white space transmission is allowed
• Unless approved by OfCom based on an approved database
– The database provides information where the white spaces are
– Cell size of around 10 kilometre
• White space technologies could be rolled out by end of 2013

4. TV White Space: Possible Use cases

•
Asset tracking of goods on the move
Machine –to- Machine communication
Electronic and media content delivery
Traffic management and road pricing
Networking for Smart Grid
Rural broadband
Remote health monitoring & diagnosis

5. Beyond 4 G: METIS
Diversity of capabilities and use cases means inefficiency in a connected world!

6. METIS: Goals

7. Raspberry Pi Foundation
• Since late 80s/early 90s there has been a step change
– the younger generation has become a pure consumer of
computer/computing products!
• No one tries to innovate with a hands-on approach
– It is expensive and cumbersome. No one designs/cuts code
– Much easier to buy tools or download freebies
– All needs have seemingly been catered for; a passion killer!
• Training teacher in hands-on computing is now available
– Look at http://www.computingatschool.org.uk/
Raspberry Pi Foundation has been set up to reverse that trend

8. A-level Computing Decline

9. What is Raspberry Pi?
• The Raspberry Pi Foundation is a UK registered charity
– It exists to promote the study of computer science and its related
topics
• at school level, and to put the fun back into learning ‘computing’
• RPi manufactures and distributes an ultra-low-cost computer, for
use in teaching computer programming to children
• This computer has many other applications both in the developed
and the developing world.
• The first product is about the size of a credit card,
– designed to plug into a TV.
• The price is around £25 for a fully configured system
• or £35 with 2 port hub and network
• All software tools to load software on Raspberry Pi is also made
available
• 17000 units are ready to be distributed to UK schools/colleges freed
of charge
– Contact the foundation directly fir further details
