FIPS 140-2, IEEE 802.11i and WPA2 in 3eTI Wireless Products | |
April 29, 2005 | |
| 3eTI's wireless access points, client devices, and security server have been designed as FIPS 140-2 Validated™, 802.11i compliant and WPA2 certified —thereby providing extremely high levels of security to the enterprise customer, while ensuring interoperability with the spectrum of other brands of COTS, WPA2-certified wireless equipment in the market today. WPA2 provides enterprise and consumer Wi-Fi users with a high level of assurance that only authorized users can access their wireless networks. | |
FIPS 140-2, IEEE 802.11i and WPA2 for Security, Interoperability and Affordability | |
November 4, 2005 | |
| 3eTI has integrated FIPS 140-2, 802.11i and WPA2 into its products. Once thought to be mutually exclusive, there are, in fact, significant differences: FIPS 140-2 provides for the protection of sensitive but unclassified data; IEEE 802.11i provides for standards-based security improvements; and WPA2 certifies interoperability and ensures affordability to the customer. This paper discusses developing trends in commercial WLAN for the Department of Defense and demonstrates how 3eTI products measure up against emerging requirements. | |
Enabling HIPAA Compliant Patient Care | |
2003 | |
| The Health Insurance Portability and Accountability Act (HIPAA) mandates secure and private access to protected health information. Protected information includes almost all identifiable health records and data that can be transmitted or maintained in any format. One provision of HIPAA calls for privacy and the establishment of policies that restrict access; another calls for security of sensitive consumer data. 3eTI products can help entities required to follow HIPAA regulations by offering technologies that address many aspects of the requirements with cost-effective, wireless applications. | |
Mesh Networking Architectures and System Topologies | |
2005 | |
| Mesh networks, which are flexible, easily deployable and scalable, have gained popularity in a variety of applications. As a result, Wi-Fi systems have become popular with municipalities, service providers and industrial customers who desire wireless service in areas not currently served. To develop effective wireless solutions, each customer must examine their needs and determine the capabilities they need to ensure the equipment they purchase meets the bandwidth and latency requirements of their particular mesh networking application. | |
Security Mechanisms in 3eTI Products | |
| 3eTI has developed an innovative Dynamic Key Exchange (DKE) technique for effective key management in wireless systems. This technique involves a security server, an access point and multiple wireless client devices. 3eTI’s cross-layered approach to security provides a more comprehensive protection of data flow and meets requirements for authentication as required by the Department of Defense. | |
802.11 WLAN Architecture – Best Practices | |
February 16, 2005 | |
| The two major architectural approaches for deploying Wireless Local Area Networks (WLANs) across an enterprise — the "distributed" and "centralized" approaches — each impact deployment costs, the level of security, and the manageability of the installation. This paper compares and contrasts the two approaches, discusses the use of VPN technology, describes the impact of 802.11i WLAN security standards on existing deployments, and elaborates on how 3eTI products offer capabilities and features that meet the highest industry standards. | |

Analog Tone Detection using the Quadrature Receiver | |
January 5, 2005 | Download PDF |
| Methods of detecting an analog tone of a specified frequency and duration include a diversity of well-known techniques that span the range from mechanical devices to hardware circuits to software solutions. This paper presents a simple technique known as the quadrature receiver, which although capable of being implemented in hardware, is usually implemented as software running on a digital signal processor. | |
Digital Phase Modulation | |
August 7, 2003 | Download PDF |
| The fundamental concept of digital communication is to move digital information from one point to another over an analog channel. More specifically, passband digital communication involves modulating the amplitude, phase or frequency of an analog carrier signal with a baseband information-bearing signal. | |
Bit Error Rate Simulation Using Matlab | |
August 19, 2003 | Download PDF |
| Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error-rate testing of modems. | |
Selected Comments on Scrambler Security | |
September 16, 2003 | Download PDF |
| Analog scramblers provide an acceptable level of communications security for many applications; however, the specific level of security these scramblers provide is nearly impossible to precisely quantify. Most users of scramblers have little choice but to believe whatever their vendor tells them about the security level provided, which is invariably "the best in the industry." | |
