The Wilson Small Office / Home Office (SOHO) DualBand cellular amplifier repeater.
The SOHO can typically cover 1-2 rooms (depending on outside signal strength) and handle up to 5 users simultaneously.
The Wilson SOHO Wireless Amplifier greatly improves signal strength inside a building when using your cell phone. It does this without physical connection to your phone allowing you to walk around freely during a call. It even allows up to two cell phones and/or Data Cards to be used simultaneously. Works for most 800MHz and 1900MHz range networks including CDMA, TDMA, GSM within the US and Canada (NOTE: Will Not work for Sprint/Nextel iDen or Mike/Telus Networks.)
Using the directional antenna included in this kit will improve the coverage area inside. This directional antenna focuses a higher gain towards your provider's tower. It also reduces the separation requirement between the inside and outside antenna to about 20 ft (inside and outside antenna must be pointed away for each other.) The down side of using a directional antenna is that it focuses towards one direction. If you are trying to improve the signal for multiple service providers and their towers are in opposite directions, the coverage of one service provider may be weaker.If this is the case, consider a SOHO kit with an omni directional outside antenna.
The Wilson SOHO is a small, bi-directional cellular amplifier that delivers service levels consistent with what would be expected in areas of high cell network coverage. They amplify a weak or shadowed cellular signal and repeat it in an in-building small office / home office (SOHO) applications. When using this cellular signal amplifier in conjunction with Wilson antennas, the outside antenna will collect the cell tower signal and send it through the cable to the amplifier. The signal is then amplified and broadcast from the inside antenna to the surrounding area. Cell phones and cellular data cards in that area then communicate with the improved signal. When a cell phone or cellular device transmits, the signal is received by the inside antenna, amplified by the amplifier and broadcast back to the cell tower through the outside antenna.
