Features
Overview: The weBoost Office 300 Pro Installed Cell Signal Booster (75 Ohm) (#479047) is designed to improve the cell signal inside your small-to-medium business, retail space, or warehouse, providing best-in-class coverage for up to 15,000 square feet. Boosted signals result in fewer dropped calls and dead spots, clearer voice calls, and faster data rates for both customers and employees. The multi-user Office 300 improves cell signals on all U.S. carrier networks simultaneously, including Verizon, AT&T, T-Mobile, USCellular, and more. The weBoost Office 300 Cell Signal Booster is 5G, 4G, and LTE compatible, and comes with a 3-year warranty.
Professional Installation Included: The weBoost Office 300 Pro Installed cell phone signal booster includes professional installation. weBoost has partnered with OnTech Smart Services to provide turnkey installation of the indoor and outdoor antennas, the booster, and all of the cable. No cable is included in the box. The box includes the booster, the outside (receiving) antenna, the two inside (transmitting) antennas, power supply, and the 2-way signal splitter. Inside the box is an Installation Card which contains details and instructions on setting up the installation appointment with OnTech. Typical installation of the weBoost Office 300 Installed system is 4 to 6 hours.
Note: If the booster is being installed in a rental/leased property, permission from the landlord should be obtained before permanantly installing a cell signal booster system.
Outdoor Antenna: weBoost Office 300 Pro Installed includes a 25" external omni-directional outdoor (receiving) antenna. The antenna has 9dBi higher gain to reach greater distances, and continuously scans 360° to capture the strongest signal. The IP65-compliant antenna is made with weather-resistant materials and is able to withstand extreme temperatures from -40°F to 176°F. The outdoor antenna comes with an L-bracket, U-bolts, and other hardware for pole- or flush mounting. It has a female F-connector on the bottom for connecting the cable.
Indoor Antennas: The Office 300 Pro Installed comes with two 9.4" diameter indoor low-profile dome (transmitting) antennas for maximum coverage throughout the commercial space. These flat dome-style antennas have a 6" shaft for attaching it to drop ceiling tile or hard surface ceiling. The antennas cover cellular bands and Wi-Fi from 608 through 2700 MHz.
Status Lights: The Office 300 booster unit has a color LCD touch screen for monitoring the performance of the booster. You can view the status of each band, including the uplink and downlink signal strength, and disable/enable individual bands (for expert installers only). When viewing band performance, you can see at a glance the signal strength of each band by its color-coded indicator:
- Solid Green: The band is functioning properly.
- Solid Yellow: Indicates a band gain reduction because of an oscillation condition. You should increase the separation between the indoor and outdoor antennas, then reboot the booster to reactivate the band.
- Solid Red: Band has shut itself off due to a severe oscillation condition or repeated oscillation. Repositioning the antennas is suggested, then reboot the band.
- Gray: The band has been disabled.
Signal Strength: Before installing the booster, you should check your current cellular signal strength using your phone. Bar graphs are not an accurate indicator of signal strength. Most phones allow you to switch from bar graphs to a digital readout of signal strength (in dBm). There are also available 3rd party apps, such as OpenSignal or Speedtest, for testing signal strength. Typically, the range of signal strength is between -110 dBM and -30 dBM, with a figure closer to zero being the strongest. A general indication of signal strength is as follows:
Signal Strength | Excellent (4 bars) | Good (3 bars) | Fair (2 bars) | Poor (1 bar) | No Signal (0 bars) |
---|---|---|---|---|---|
4G / 5G | -90dBm or better | -91 to -105dBm | -106 to -110dBm | -111 to -119dBm | -120dBm or less |
Gain Improvement: Increasing your signal strength by only 3dB means you have essentially doubled the power and signal amplification. A 6dB increase equals 4x the power, 10dB increase is 10x the power, and a 20dB increase shows a 100x signal improvement.
Benefits: The weBoost Office 300 Pro Installed helps increase the signal strength in typically weak signal areas. With stronger signals, cell phones don't have to work as hard to find a signal, extending battery life. Data rates are increased so your customers and employees will experience fewer dropped calls and delayed texts, while enjoying faster data speeds and improved video streaming.
