Recently, Lintratek Technology completed a mobile signal coverage project for a small business store using the KW23L tri-band mobile signal booster paired with just two antennas to deliver reliable indoor coverage.
Although this was a small business installation, Lintratek treated it with the same dedication as larger deployments, delivering top-tier service. The KW23L mobile signal booster operates at 23 dBm (200 mW) of power—enough to cover up to 800 m² and drive four to five indoor antennas under normal conditions. Some readers have asked why we selected a higher-power mobile signal booster, since a 20 dBm (100 mW) device can typically support just two antennas.
Mobile Signal Booster for Small Business
The KW23L mobile signal booster supports three bands—GSM 900 MHz, DCS 1800 MHz, and WCDMA 2100 MHz—providing 2G and 4G coverage. In China, the 2100 MHz band is also used for 5G NR; in our signal tests, Band 1 (2100 MHz) functioned as the 5G frequency.
KW23L Tri-band Mobile Signal Booster
In the field, theoretical coverage often clashes with on-site challenges. In this project, two main factors influenced our antenna and cable layout:
Weak Signal Source
The available signal at the site measured around –100 dB, requiring extra gain to overcome.
Long Cable Runs
The distance between the signal source and the target coverage area necessitated long feeder cables, which introduce loss. To compensate, we deployed a higher-gain, higher-power booster to ensure consistent signal quality.
Thanks to meticulous design and installation, the project was delivered without any coverage gaps, and the client now enjoys robust mobile reception throughout their store.
Whether it’s a small business or a large-scale commercial projects, Lintratek Technology offers the same high level of service to every customer.
