Figure 2-54 Remote Unit – 7/5/3 band
2.2.1.1 Functions and features
- Supported frequency band
 3_band RU: SMR800, PCS, and 2.6G TDD
 5_band RU: 700M, 850M, PCS, AWS, and WCS
 7_band RU: 700M, SMR800+850M, PCS, AWS, WCS, and 2.6G TDD
- VSWR measurement function for checking VSWR of the connected service antenna
- Built-in Test tone generator in order to check uplink path verification
- Increase scalability by supporting expansion RU
 Expansion RU is connected with main RU through AUX DL/UL port by using RF cable
 Expansion RU can be added, when it needs additional frequency band other than frequency bands
being used in main RU, or additional filter attenuation in the frequency band being used in main RU. In
the latter case, the frequency band which needs additional filter attenuation must be off in main RU
and replaced by the frequency band with strengthened filter attenuation in expansion RU.
