Motorola Sensors Go with ZigBee™ Protocol for Wireless Networking

ZigBee Technology from Motorola Provides Interoperability between Multiple Sensors for Automation, Control, Monitoring and Maintenance

PHOENIX, AZ -- September 23, 2003 -- Motorola, Inc.'s (NYSE: MOT) Semiconductor Products Sector is offering acceleration and pressure sensor integrated circuits (ICs) which are designed to enable sensor networks with the convenience and reduced installation expense of wireless technology, through their compatibility with the ZigBee™ protocol. These ICs are designed to help enable the deployment of wireless sensor networks in environments as diverse as a factory floor to a game console in the family living room.

Sensors compatible with the ZigBee wireless standard offer convenience and cost savings by enabling easy re-configuration and eliminating the need for re-wiring once installed. Wireless sensor networks should obtain real-time data on systems or devices without requiring physical contact, enabling remote monitoring and reduced labor costs. These sensors use MEMS (micro-electromechanical systems), a micron-sized mechanical technology, to sense, process and/or control the surrounding environment.

ZigBee is a wireless networking technology based on the newly defined IEEE (Institute of Electrical and Electronics Engineers) 802.15.4 standard. Designers of wired sensor networks should benefit from using Motorola's flexible ZigBee technology to develop wireless sensor networks. Adoption of the ZigBee protocol as a single wireless standard helps original equipment manufacturers (OEMs) realize cost reductions and speed time to market versus current proprietary wireless or wired sensor networks.

Wireless Sensor Applications Enabled by the ZigBee Standard
Industrial - Motorola's sensors are optimal for building automation where they can be used to measure temperature, pressure, smoke and motion. The feedback response can trigger additional control functions such as turning systems on or off, sounding alarms and preventive maintenance.

Logistics Management - Wireless acceleration sensors can be attached to high value assets in a manufacturing line to provide location status and orientation for inventory and work-in-progress monitoring. The wireless sensor then becomes embedded within a final product for tracking location, product position and orientation during shipment to the end user. After installation in the end location, the product may continue to use the embedded sensor with the ZigBee protocol to link into a new wireless network.

Consumer - Game peripherals and PC joysticks use low-g acceleration sensors to respond to tilt and motion, providing more accurate and responsive end user gaming experiences. The combination with wireless should allow the player the freedom to move about the room while playing, unfettered by wired connectors.

In addition to these applications, a range of industrial, consumer, medical, and automotive applications can benefit from wireless sensors utilizing the ZigBee standard. Some of these include:

- Industrial: energy management, HVAC, proactive maintenance, vibration measurement, bearing wear monitoring, seismic detectors, inclinometers, robotics, security systems, security enhancement equipment - Consumer: lighting and heating and ventilation remote controls, security and remote monitoring systems, household appliances, PC peripherals, entertainment systems control, interactive toys, virtual reality input devices

- Healthcare/Fitness: sports medicine equipment, physical therapy/rehabilitation equipment, ergonomics tools, pedometers

- Automotive: telematics and occupant safety enhancement features

"Sensors compatible with the ZigBee standard are a natural fit within Motorola's semiconductor portfolio," said Behrooz Abdi, vice president and general manager of Motorola's Radio Products Division. "With our leadership in the ZigBee wireless networking standard, we are able to merge our position as the number one supplier of automotive microcontrollers, our MEMS-based sensor devices, and our leading IEEE 802.15.4 RF technology to create cost-effective end product solutions."

Industry analyst firm Allied Business Intelligence estimates the worldwide potential for short-range, low data rate wireless at 150 million units for 2003. The impact of industry standardization is expected to at least triple the market within a few years according to analysts at IDC Semiconductors. Early drivers for building management systems include wireless sensor networks for energy management enabling real-time pricing and load balancing. Cost savings, resulting from logistics management and preventive maintenance, drive industrial sensor networks.

From everyday devices used in the home to more sophisticated highly configured sensor networks, OEMs can expect to use acceleration and pressure sensors compatible with the ZigBee wireless standard for star, mesh or cluster tree network topologies. Together with sensors compatible with the ZigBee wireless protocol, Motorola's embedded MCUs and RF transceiver data modem offer a full suite of products for sensor networks, simplifying vendor selection for the OEM.

"In the world of sensors, the trend is toward increased system functionality," said Brett Richmond, vice president and general manager of Motorola's Sensor Products Division. "Wireless sensor integration is the next step. The ZigBee protocol opens up opportunities for a wide variety of customer applications to obtain real time data on systems and devices in secure transmissions."

Features and Benefits
- Architectural Flexibility: Motorola's solutions compatible with the ZigBee standard are designed for maximum system flexibility, utilizing standard hardware interfaces for OEM sensor and embedded processor choice. The Motorola RF transceiver operates in the global 2.4 GHz band, allowing for one system design to be used worldwide.

- Secure Communication Transmission: By using symmetric key with 128-bit AES (Advanced Encryption Standard) algorithms the communication protocol helps to promote security in its communication transmission.

- Standards-Based: The IEEE 802.15.4 and ZigBee technologies, combined for a standardized network protocol, help to reduce development time for the OEM. Wireless sensors can now follow a standard that has exceptional network control, scalability, interoperability, low power consumption, and reliability. This helps to increase cost-efficiency and allows for widespread wireless sensors for automation, control, monitoring and maintenance.

- Established Provider: Sensors compatible with the ZigBee wireless networking standard come from Motorola - a semiconductor manufacturer that understands wireless technology and knows the needs of the market segments. According to Gartner Dataquest, Motorola is the market leader in wireless communication semiconductor sales and has been producing wireless technology for 70 years.

Availability
Motorola's acceleration and pressure sensors are currently available. Engineering samples of the ZigBee products from Motorola are expected to be available in November.
