NTS has years of experience performing compatibility and functionality testing specifically on wireless products. Testing covers all the latest and greatest protocols and technologies, including Wi-Fi, ZigBee, Bluetooth, and even cellular technologies (e.g., CDMA, etc.).
NTS offers testing services such as:
Wireless Hardware Testing
NTS's Wireless Testing covers a wide variety of wireless technologies including popular wireless standards like 802.11b/g and cellular standards like CDMA. (Note: The basic test points below may not apply to all wireless protocols.)
The NTS Wireless Interoperability Certification test suite has the ability to test your product across most of the wireless chipsets in the market today. NTS will also test your device across a wide array of access points (AP's), PC Cards, Laptops, Desktops (with PC Card Readers), operating systems, service packs and device system specs.
The major test points would include:
Ad-Hoc Mode
Installation
Throughput Analysis and File Integrity (e.g., MPG, MP3, AVI, PDF and TXT).
Multimedia Streaming Analysis
Interoperability with an array of Wireless PC Cards
Power Management
Infrastructure Mode
Installation
Throughput Analysis and File Compare / Integrity (e.g., MPG, MP3, AVI, PDF and TXT).
Multimedia Streaming Analysis
Interoperability with various Wireless PC Cards, PCI Cards, & AP's
Backend AP Ethernet connection to Internet
Throughput Analysis with WEP enabled 40bit/64bit
Throughput Analysis with WEP enabled 104bit/128bit
All of these test points are typical operations that an end-user would perform on a daily basis, determining how well your product will perform in the "real-world."
NTS can also perform testing on your wireless router. A wide variety of wireless routers (for both home and business) are available on the market and require testing to verify that they can function with a wide variety of access points and other routers.
NTS can also perform the following tests to validate your wireless device:
RF Testing - These tests are designed to verify a device-under-test�s performance under various spectrum conditions. Tests can be executed as a single suite or individually.
Flat Channel - These tests evaluate the ability of the device-under-test to function under controlled interference conditions. The transceiver is typically connected by means of a coaxial connection directly into the measurement layout. Several noise patterns are introduced with various settings and the functional response of the device-under-test is observed by measuring data transmission characteristics, such as throughput, latency, etc.
MultiPath - These tests focus on the response of the device-under-test to marginal multipath conditions such as spreading delay, Rayleigh fading, etc. Results produced by executing this test allow for accurate product performance predictions in the "real" world.
Custom Specification - NTS also has the capabilities to develop and execute test suites to test devices for proprietary manufacturer specifications. The Physical Layer Laboratory at NTS's facility has extensive experience in physical layer analysis for most communication technologies available today. Thus, customized RF parametric suites are available in order to facilitate successful and timely product release.
Wireless Performance Field Testing - This test suite addresses throughput vs. distance under multiple conditions. In order to measure performance, NTS has developed three (3) typical "real-world" test environments in which we measure performance: 1) Commercial Business environment, line of sight; 2) Indoor Office environment, non-line of sight, and 3) Open Field environment, line of sight testing. Each test environment is selected to measure particular commonly encountered wireless situations. For more information, see the NTS Wireless Performance suite.
Wireless Software Testing
NTS's Wireless Testing also covers a variety of software designed to support wireless technology. The most common wireless support software is the Connection Manager.
In NTS Connection Manager testing, our goal is to simulate a "real-world" environment and exercise your software product to determine its functionality, compatibility and stability. The following are examples of the various test environments which could be incorporated into testing, depending on your own internal testing (Note: Some of these environments may not apply specifically to your particular product or testing needs; however, NTS wants to highlight our extensive and versatile testing capabilities):
Test Platforms - NTS has a large inventory of test platforms. NTS systems are primarily "Tier 1" platforms, from major manufacturers over the last 5 years, such as HP, IBM, Compaq, Dell, Gateway, and so on. NTS also has an inventory of Macintosh platforms, for testing hybrid software products. Additionally, NTS have a large array of servers and workstations, which allow us to simulate both standalone and enterprise test environments.
Wireless PC Cards and Access Points/Routers - NTS also has a large inventory of Wireless PC Cards and Access Points, covering all of the various wireless chipsets, so you can test with the most common products currently on the market and those that have been released in the recent past.
Operating Systems - NTS can test with all popular operating systems, including using their various service packs/security updates. NTS can perform testing with all Microsoft Windows and Apple MacOS operating systems, plus Linux and Unix operating systems in various flavors.
Localization Testing - NTS can also test across 35 different languages under localized versions of the MacOS and Windows operating systems.
Third-Party Applications - A number of anomalies may be encountered when due to interoperability with other products. For example, loading the Windows System Tray with multiple memory resident applications, such as anti-virus and firewall applications, can cause issues that would not normally be found through normal operations. NTS can also test with various web browsers (e.g., Internet Explorer, Netscape, Mozilla, Firefox, Safari, Opera, and a host of others) for browser-based software.
Third-Party Applets/Utilities - NTS can test your different applets, utilities, and media frameworks for testing your product (e.g., versions of DirectX, Java applets, XML applications, QuickTime, Real, Media Player, etc.).
Third-Party Hardware - NTS has a large inventory of hardware devices such as USB, IEEE-1394, PCI Adapters, AGP, etc. Configuring a system with various devices and loading their drivers has an affect on the software-under-test, especially when the application is accessing these devices (e.g., wireless connection manager using third-party wireless adapter, etc.).
