Review on Cisco Microcell Wireless Booster Antenna by Joseph Marshall

My home office has poor cellular reception due to dropped or dropped calls. AT&T said I was in a dead zone and nothing could be done. I've considered amplifiers that require an external antenna, but they're impractical for our home. AT&T has discontinued the microcell but continues to support it and used/refurbished ones are available on eBay and Revain. I took a chance with a Revain refurbished unit and am glad I did as I now have a strong signal, 4 out of 4 bars on an iPhone 7 with very good connectivity and voice. The installation went well, step 1 - the power supply worked well. Step 2 - The automatic software/firmware update took 3 power cycle attempts, but it was updated. Step 3: It took a while to check my GPS location but it worked. Step 4 - Activation went well. The instructions (available from AT&T) state that the entire process can take up to 90 minutes, I ran it and it ran in about 1 hour. Everything you need to install and activate your microcell is available online from AT&T. After logging into your account, search for Micro Cell Activation. Note. This requires an Ethernet connection to the router/modem. I have 50 feet of Category 6 Ethernet cable in my attic. The device also needs to receive GPS signals to verify location, possibly near a window.
