Portable DAS Coverage Simulation Test Kit

เนื่องจากผู้ให้บริการเน้นการสร้างจากแมโครเพื่อให้การเชื่อมต่อ LTE ในอาคารอยู่ในระดับเดียวกันกับแนวโน้มของระบบเสาอากาศแบบกระจาย (DAS) และการปรับใช้เซลล์ขนาดเล็กโดยผู้ให้บริการเจ้าของสถานที่และองค์กรต่างๆมีความแข็งแกร่ง ดังนั้นการทดสอบการวางแผนของ DAS จึงกลายเป็นสิ่งสำคัญอันดับแรกสำหรับผู้ให้บริการและผู้สร้าง DAS

ชุดทดสอบการจำลองสถานการณ์ครอบคลุม DAS ของ BlueBat เป็นโซลูชันชั้นนำของอุตสาหกรรมของการจำลองการครอบคลุม DAS ซึ่งรวมถึงเครื่องรับสัญญาณนำร่อง FDD-LTE มือถือ (เช่นสัญญาณจริงที่สร้างโดยสถานีฐาน) และเครื่องส่งสัญญาณนำร่องขนาด FDD-LTE ขนาดพกพา ชุดทดสอบสามารถพกพาได้ด้วยกระเป๋าเดินทางใบเดียวและพนักงาน 1 คนก็เพียงพอที่จะทำการทดสอบการจำลองสถานการณ์ครอบคลุม DAS ด้วยชุดนี้ผู้ใช้สามารถประมาณความครอบคลุม DAS ในขั้นตอนการวางแผนที่ใกล้เคียงกับความครอบคลุมที่แท้จริงในอนาคต

Portable solution for Indoor DAS coverage Simulation

All the instruments and accessories in Feeler2 portable DAS coverage simulation test kit can be carry in one suitcase. And the set up can be done with one staff minimum.
As a simulating signal source, Pilot Transmitter in the kit is able to output FDD-LTE modulation signals. The cell signal parameters (Channel, PCI, RSRP, RSRQ, SINR, etc.) are collected by the receiver by means of walk test, and the actual coverage of the base station is simulated to estimate the coverage of base station signals, further confirm the locations and quantity of base stations and provide accurate data for the layout of indoor distribution system.

Support CW analysis for propagation model tuning

AsAs a simulating signal source, pilot Transmitter in test kit is able to output CW signals within 700MHz to 2700MHz. The CW signal strength are collected by the receiver with its spectrum analyzing function.

APP remote control and simple deployment

The Transmitter is a kind of engineering test instrument, which should be easy to deploy and operate for tests in various scenes. Pilot Transmitter in test kit is controlled by APP via Wi-Fi within 10m, facilitating remote operation and avoiding radiation injury caused by radio waves in high-power transmission of signals.

User-friendly Android operating system

Receiver in the kit is based on Android OS. It can be operated as same as a regular mobile phone. Even inexperienced user can easily obtain test results after simple training.

  • Parameters can be set rapidly by clicking and sliding.
  • Test results can be display and output in various format.

Additional spectrum analyzing function

Receiver in the kit also serve as a hand held size real spectrum analyzer. Support from 10MHz to 4.2GHz, with ultra-portable design and high sensitivity. A good choice for setting up and maintaining transmission system, providing added value for clients.
