7 1 - Signal Boosters General Information
8 What is a Signal Booster? Definition Device that automatically receives, amplifies, and retransmits on a bidirectional basis, the signals received from base, fixed, mobile, or portable stations, with no change in frequency or authorized bandwidth. Different names Signal Booster / BDA / Repeater What does it do? A Signal Booster takes an existing signal, amplifies it, and retransmits it to a space that is receiving weak or no signal in order to extend the radio coverage.
9 Types of Signal Booster FCC Part 90 Signal Boosters Class A Narrow-band (channelized) Just amplifies the signals intended to be retransmitted. Class B Broad-band Amplifies all the channels within certain bandwidth. Types depending on intermediate filtering Full Band (Class B) Band Selective (Class B) Adjustable Bandwidth (Class B) Channel Selective (Class A)
10 Types of Signal Booster depending on intermediate filtering 1 Full Band Full band filtering Cellular applications 2 Band Selective Sub-band filtering Cellular applications 3 Bandwidth Adjustable Programmable BW filtering Radio and Cellular applications 4 Channel Selective Channel filtering Radio system applications
11 2 Fiplex Signal Boosters
12 Key parameters Intermediate filtering capabilities Defines the type of signal booster. Gain Dictates the smallest signal the SB can handle. Attenuation Range In applications where strong signals are present, configurable attenuators are needed. Output Power Dictates how large the provided coverage area can be. Automatic Gain Control (AGC) The AGC prevents the SB of having more than the maximum rated output power at its output.
13 Signal Boosters for Public Safety Adjustable BW Signal Boosters Suitable for Public Safety applications. Flexibility to choose the sub-band and necessary width. Good rejection to interference. For smaller applications. Accepted by many jurisdictions. Channel Selective Signal Boosters Suitable for Public Safety applications. Just amplifies the desired channels. Optimum use of the output power. Maximum flexibility. Excellent interference rejection. For larger applications. Top Performance. Accepted in all jurisdictions.
