HC-SDMA: it is and it isn’t …
PWDSL:

     it can use a smidgen of unpaired spectrum in 1.5 – 2.5 GHz
      area, thrives on multipath, non LoS
     it is not FWA, BFWA or 2G, 2.5G, 3G, even 4G (?)
     it is not highest-speed mobility (e.g. TVA)
     it is very spectrally efficient (x40, soon x 80 times 2G
      mobile)
     it does offer true broadband, not wideband
     it does have massive capacity c.f. other approaches
     it is economical, highly competitive with ADSL but also
      offering true portability
     it is HC-SDMA or Portable Wireless DSL or MBWA or
      iBurst™, likely IEEE 802.20 (TDD)
     it needs a single, unpaired 5 MHz initially, prudently 10
      MHz for longer term
                                                          5
So is HC-SDMA so different from (B)FWA,
and cellular mobile ?

  ubiquitous Broadband Wireless Access is the new
 utility for the 21st century.
  it is not a voice-centric system, it is a pure-IP
 data approach
 true user BB data rates, long range and indoor,
 high capacity, portable and nomadic
  no directional TS antennas, no installation – the
 premise is that there are no premises (so TS not
 “CPE”); no “architectural acne”
  features intra-system hand-over and inter-system
 (RLAN) but with highest security (even before
 VPN use)

                                               6
Why unpaired spectrum etc?

   uses TDD, adaptive antenna technology and spatial coding
   (SDMA) to give unprecedented capacity, range, spectrum
   efficiency*
   TDD means the eigenvector solution to the channel
   weighting problem is well posed; for FDD the solution can
   forever only be approximate
   Core technology (ArrayComm) deployed in >0.3 m base
   stations globally and soon for >0.25 m lines of FWA
   MAC layer and extensive adaptation features mean carrier
   class, with good granularity for traffic handling, overall
   more than matching ADSL wired in every sense.
   leverages very best established technologies in a new mix
   and in a new, low-complexity architectural arrangement

* 4 bps/Hz/cell, then double this

Mobile Broadband Access System
for Security, Contingency and

                             24
Broadband Communication Needs of the
Security Community



  Secure, survivable wireless broadband on
  demand, with wide coverage
  Reliable, available in emergencies
  Video and VTC links to mobile command and
  monitoring platforms
  Transportable platforms to cover contingencies
  Ability to deploy dedicated network or leverage
  commercial networks with real-time
  prioritization
  Interoperability
                                               26
Emergency Response Info-Communication
Requirements

Disaster response & contingencies may involve
multiple state and local agencies as well as
NGOs
Response rapidity, flexibility and efficacy are critical factors in
 mitigation and recovery
Possible terrorist actions during and after disasters amplify the
 risks
 Response efficacy increasingly dependent on
up-to-date, on-site, high-bandwidth information
 Need for interoperability and information-
sharing applications (e.g. GIS, VTC, simulations)
 Optimal response and resource management
depends on accurate monitoring and reporting
to command levels                                27

iBurst for public sector applications

 iBurst is an All-IP mobile broadband access system, which,
 deployed over a wide area, enables multiple broadband
 services, from advanced business VPN, to affordable
 broadband access in unwired areas.
 A single dual-use iBurst network can support both
 commercial and public sector applications.
 Total priority and pre-emption allow serving the special
 broad coverage broadband communications requirements of
 institutional and government entities..
 Because of its capacity, performance, prioritization
 capability, and price points, iBurst is especially applicable to
 broadband communications requirements for emergency
 response, contingencies and disaster recovery (during
 floods, earthquakes, fires, man-made disasters, public
 disturbances, etc.).

 Priority is key requirement for
 emergency response

A key advantage of iBurst is its ability to totally or partially preempt the network’s
capacity and provide priority access to government agents
  Instantly, with a few keystrokes at Network Operations Center
  In any location – over entire network, or regionally or locally
  To any class of users – e.g. VIP and Designated Persons
  For an indefinite period of time
  This feature is v. hard to achieve on cellular networks (as circuit availability
   and switch capacity is based on short calls – less than 1 minute average)
Priority feature is especially useful
  During incidents and emergencies (e.g. Floods, Earthquakes, Fires, etc.)
     Normal commercial mobile and fixed networks get overloaded : .g. on
       9/11/2001 in New York City, demand was 1500% above system capacity
  For the massive communication needs of Emergency Responders during the
   first 12 to 48 hours:
     e.g. visual information and GIS data to and from the incident location
  For efficient Command and Control: e.g. resource allocation, decision in real-
   time
                                                                            33

  HC-SDMA argued as a suitable technology for the
  MESA family. This presentation for background.
  Excellent capacity, user rates, wide area coverage;
  simple all-IP architecture.
  Pilot is being expanded in Belfast, another planned in
  Benelux – both emphasizing Public Sector usage
  Requires very little unpaired spectrum
  Chip sets and modules for terminals available soon
  Security audit imminent, plan CESG approval
