3 3 Fixed Local Area Wide Area Wireless Landscape Broadband Narrowband User Speed in practice Bluetooth W-LAN LMDS MMDS Satellite 2G 2.5G Proprietary 3G PWDSL Mobility Freedom

4 4 Packet Service Switch (Tunnel Switch, PDSN) Content provider Enterprise VPN Application service provider ISP Billing and Service Platforms Internet DSL PSTN Cable ServiceAccess & Transport i-BURST Subscribers i-BURST Base Station i-BURST Base Station i-BURST Base Station WAN HC-SDMA or Portable Wireless DSL (PWDSL): Extension of Wired Network Leverages existing infrastructure Compatible with all IP services, applications

5 5 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 …

6 6 So is HC-SDMA so different from (B)FWA, and cellular mobile ? ubiquitous Broadband Wireless Access is the new utility for the 21 st 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)

7 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 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 Why unpaired spectrum etc?

8 8 Adaptive Antenna Concept as 1 (t)+bs 2 (t)as 1 (t)-bs 2 (t) +1 User 1, s 1 (t)e j  t 2as 1 (t) 2bs 2 (t) User 2, s 2 (t)e j  t Users’ signals arrive with different relative phases and amplitudes at array Processing provides gain and interference mitigation

9 9 HC-SDMA security summary Security integral part of AI protocol and h/w design Supports advanced security mechanisms Mutual authentication of TSs and CSs Protocol security architecture to overcome known security attacks Overcomes all known ‘Wi-Fi’ attacks. Transparently enables end-to-end network, transport and application layer security mechanisms

10 10 HC-SDMA Summary A new benchmark in spectrally efficient portable Internet access systems Cost effective, secure delivery of massive data Adaptive array technology and TDD spectrum End to end IP transport, low latency Flexible, evolvable platform to generate new class of broadband and personal Internet services on wide area, carrier grade networks Seamless handover, intra-system and inter-RLAN Australia and S Africa now, soon a number of other countries

11 11 HC-SDMA as PWDSL Network Performance * i- BURST CDMA 2000 1XRTT 3G GPRS (Mbps)  More subscribers - a 50:1 OSR example shown here  More data  More revenue Data rate per user * per 5 MHz only unpaired, initial rating; capacity likely doubled after 12 mos.

24 24 A Nationwide High-Performance Mobile Broadband Access System for Security, Contingency and Disaster Response

25 25 Safety and security communications requirements & drivers

26 26 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

27 27 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

29 29 iBurst for Public Sector Applications

30 30 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.).

32 32 An iBurst network enables efficient security and emergency response

33 33 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

41 41 A Continuity of Government Scenario A dirty bomb has been detonated in a major city’s central district Key government officials are moving about the city to new locations iBurst provides 1Mbps bandwidth to a user terminal anywhere within coverage area (today: 2 Mbps soon and 8 Mbps later) Removes requirement to have a pre-determined site to move key personnel to Relocate PC laptops from everyday office Connectivity in transit Video teleconference Television news network Access to critical systems still operating Restore office at selected unwired site

42 42 Nuclear Plant Security Zones Owner Controlled Area Protected Area Vital Area Access Control Points Protected Area Double Fence iBurst-enabled Video Security Perimeter An iBurst base station can provide connectivity with many data sensors, including video surveillance, substantially beyond the patrolled perimeter of the nuclear power plant

43 43 System and Network Performance Parameters

44 44 Quantifying HC-SDMA Performance 20 Mbps per cell (15 Mbps Downlink, 5 Mbps Uplink) today Up to 15 Km range today Up to 1.06 Mbps downlink, Up to 350 Kbps uplink per user today Self-optimizing, auto adaptive modulation control (maximizes efficiency) Hundreds of simultaneous high data-rate users per cell Protocol extends to 17 Mbps per user; uplink scales, unlike ADSL Self organizing, good neighbor (decoupled) cells High performance is maintained at edge of cell Mobility up to 100 Km/h today Seamless IP handover, intra- and inter- system Excellent (MAC) access fairness Enables bandwidth on demand, SIP and full IETF compliance

45 45 Security, Priority and Attack Robustness Strong survivability through IP transport Rapid deployment through range, bandwidth and standard fixed and mobile (modems) terminals Network elements and service providers are managed by the network Standard IP architecture allows using common set of emergency applications independent of access method
