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

HC-SDMA: it is and it isn’t … HC-SDMA: it is and it isn’t …

So is HC-SDMA so different from (B)FWA, and cellular mobile ?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 approachtrue 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)

7

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 approximateCore 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

Why unpaired spectrum etc?Why unpaired spectrum etc?

Secure, survivable wireless broadband on demand, with wide coverageReliable, available in emergenciesVideo and VTC links to mobile command and monitoring platformsTransportable platforms to cover contingenciesAbility to deploy dedicated network or leverage commercial networks with real-time prioritizationInteroperability

27

Emergency Response Info-Communication RequirementsEmergency 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

iBurst for public sector applicationsiBurst 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 responsePriority 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
