Key Considerations for Cellular Wireless Testing

　　Small Cell is a base station device with low transmission power and small coverage. As a supplement to 3G/4G macro cells, Small Cell enables operators to provide users with better wireless broadband voice and data services at a lower cost. Small Cell is a low-power wireless access node that works in the authorized spectrum and covers a range of 10~200m. In comparison, the coverage range of macro cells can reach several kilometers.

　　Small Cell products are more flexible and can be divided into home Femtocel (2×50mW), outdoor Picocell (2×1W, outdoor blind spot filling/heat absorption), indoor Picocell (2×125mW, enterprise-level indoor coverage), and Microcell (2×5W, outdoor blind spot filling), all of which are managed by operators.

　　Small Cell can be used indoors and outdoors to fill coverage gaps, absorb hotspot services, and improve network capacity. Small Cell and macro cell multiple layers form a HetNet heterogeneous network. Through the joint use of macro-micro collaboration technology and anti-interference technology, network capacity can be increased several times or even higher, greatly alleviating the capacity pressure of wireless networks.

　　Similarly, it is possible that WIFI and Cellular will be tested together in the future.

　　LitePoint not only provides test systems, but also provides a variety of complete software and hardware solutions to help customers enter the production stage of mass-produced devices such as smartphones and tablets as quickly as possible.

　　Litepoint's IQxstream, in conjunction with its IQvector, fully covers 2G GSM/GPRS/EDGE, 3G WCDMA/TD-SCDMA/CDMA2000, and TD-LTE and FDD-LTE. For users, unified test equipment and unified test solutions meet all their needs from LTE to LTE-A.

　　Liteport IQxel is an easy-to-deploy single-box test solution that quickly tests 802.11 a/b/g/n/p/ac and Bluetooth 1.0, 2.1, 3.0 and 4.0 devices. Most wireless test systems on the market today can only test a single wireless standard. Testing multiple standards usually requires multiple testers and lines. However, moving devices between lines is not only time-consuming, but also carries the risk of insertion damage. As insertion and testing time increase, overall test time and cost will increase proportionally. "Simple point-to-point RF cable connections minimize setup errors and improve reliability for non-signaling tests. This method increases the speed of testing a single phone by 2 times, and 6 times for testing 4 phones at the same time. For example, the traditional method takes 150 seconds to test WCDMA (3 frequencies) + GSM (4 frequencies) + EDGE (4 frequencies) devices, while our solution only takes 24.5 seconds, increasing throughput by 6 times. From a cost perspective, we can save $1 on a mobile phone, so a production capacity of 10 million units means a profit of 10 million yuan!"
