Unique True Wideband Active DAS solution covering all wireless services between 150MHz and 2.7GHz with a simple modular design based around just 4 components Rapidly growing installed base across 10 countries, including Airports, Hospitals, Power plants, Government buildings, Leisure, Broadcasting and Sports venues. Operational systems are all multi-operator capable and support private PLMR, public safety, commercial cellular, 4G, multi-cast WiFi, broadband data service, specialist telemetry and other services

TRUE WIDEBAND Zinwave New Active Wideband Passive Traditional Active Suitable for larger installations Narrowband optical fiber distribution Expensive to scale for multi-services Wideband coaxial cable distribution Range limited Zinwave New Active Wideband All frequencies from 150 MHz to 2.7 GHz Scalable for any size installation Multi-service capability Lowest cost per sq foot

Zinwave Technology

Unique 3000 System Features Active Wideband, No Filtering Multiple Services from VHF through WiMax on a Single System Low Parts Count – No Service Specific Components – Simple Spares Multimode Fiber, Single Mode Fiber or a Mix MMF or SMF with Standard Optical Connectors (APC Not Required) Single Star, Double Star or Mixed Configuration Selective Routing of Services Automatic self calibration (cable loss compensation) Can carry TDD services along with FDD (Separate Tx & Rx Paths)

RADIO OVER FIBER TECHNOLOGY The Wideband approach is enabled by: Core optical technology: high frequency RF over MMF Installed base of MMF, allowing re-use Fiber agnostic means MMF or SMF can be used Wideband active Remote Unit technology High linearity, high composite power wideband amplifiers Dual Port antenna design High isolation (>40dB) twin element in single housing

3000 Key Components – low parts count Hub (Front & Rear) Optical Module Service Module Central Power Supply Remote Unit - Fiber Dual Wideband Antenna

SYSTEM 3000 ARCHITECTURE Remote Unit Secondary Hub Primary Hub Signal Sources Primary Hub feeds up to 8 secondary Hubs Secondary Hubs feed up to 8 Remote Units Secondary Hub link is fiber Remote Unit link over fiber optic cable All fiber links either SMF or MMF Single antenna with dual port Primary Hub feeds up to 8 secondary Hubs Secondary Hubs feed up to 8 Remote Units Secondary Hub link is fiber Remote Unit link over fiber optic cable All fiber links either SMF or MMF Single antenna with dual port

SIGNAL DISTRIBUTION MATRIX Hub RU Cell-CDMA RU RU PCS-EvDO 4x4 Dist. Matrix RU LTE 700 RU 4x4 distribution matrix both Primary and Secondary Hubs Configurable via the management system Enables routing of services into Hub RU AWS RU RU

3000 Key Components: Remote Units (RU) Small Wideband Remote Units, can be wall mounted or placed behind ceiling voids One unit supports any number or combination of services (VHF - WiMax) Fiber connection Remotely powered (local powering option for) Configured and Managed via the Primary Hub Requires Separate Tx and Rx Antennas Compact aesthetic design dissipating only 28W can be installed almost anywhere RU slides into wall mounting bracket

Installation Options Component Box fits in suspended ceiling frame. Many suppliers – common for WiFi A/Ps Antenna mounted on nearby ceiling tile.

DUAL PORT WIDEBAND ANTENNA Zinwave also offers unique dual port Wideband antennas for use with its DAS system: Small unobtrusive form factor Ceiling mounted Omni-directional coverage Wideband frequency range: 800 – 2700 MHz 698 – 2700 MHz (under development) Unity Gain nominal Guarantees the required isolation for Zinwave’s wideband system Mounting bracket screws into ceiling. Antenna fixed into place with locking screw. Off the shelf antennas can also be used (with the right spacing) for any specific coverage requirements

Installation Example: Zinwave Dual Wideband Antenna

ANTENNAS THAT CAN BE USED (one each for Tx and Rx) Andrew CellMax-O-CPUSE Omni; Freq: 698 - 960, 1710 – 2700 MHz Mars MA-WOLTE-2X Omni; Freq: 698 MHz - 6.1 GHz Separate the Omni Tx and Rx antennas by 20 ft to ensure 40 dB Isolation

ZINWAVE MANAGEMENT SYSTEM: EMS Intuitive, web based GUI – Resident in Hub – NO SEPARATE CONTROLLER Only Requires a Standard Browser – NO DEDICATED SOFTWARE SNMP interface from the Primary Hub, for integration into higher level NMS systems View and manage your DAS systems from wherever you are In-built software into the system elements No management system controller unit No management software to install on client pc No proprietary software required to view or monitor you DAS installations, other than a standard web browser

CARRIER APPROVALS AT&T – Approved for Network Connection Tested thoroughly in Independent lab, Bechtel – Passed for GSM, UMTS and Mixed Mode Verizon – 2G & 3G, 4G Approved, in PeopleSoft Sprint – Approved for Network Connection Tested thoroughly in Sprint RAN Labs – Passed for iDEN, CDMA, Ev-DO and Mixed Mode T-Mobile – Approved, Market Decision

PUBLIC SAFETY COVERAGE Typical Minimum RF Level Design Requirement is -95 dBm Much Lower Than -85 dBm to -75 dBm Commercial Requirements Requires Very Little Power Share in Zinwave Multi Service RU – Essentially add for Free Public Safety Often Wants Dedicated DAS Liability Issues NFPA code Requires Emergency DAS Remotes to be NEMA4 Because of Low RF Levels, a Parallel Public Safety DAS adds Little Cost to Overall Project When Included with a Commercial DAS

SUMMARY – COMPETITIVE ADVANTAGES Single System All Services Universal Components = Low Parts Count – Readily Available Spares Agnostic – Frequency, Fiber, Modulation and Protocal Scalable: Small Cost Differential – Single Service to Multi Service Easily Accommodates All Future Carrier Changes & Service Additions Immune to Band Swaps No Service Specific Components Route to Market Certified System Integrators– experts in in-building RF design and support Always supported by Zinwave engineers
