NOTE This is an example of a note used in this document that denotes important information about the text or procedure that follows it. l Preface iviRU4438 iRRH Product Description and Installation Guide Overview The iRU4438 intelligent Remote Radio Head is based on a distributed architecture with the following two essential elements: • iRU4438 iRRH • iRB1200 iBBU or vBBU The iRU4438 iRRH is a compact, outdoor microcell radio head with integrated baseband for use in the AWS band. The iRU4438 iRRH is connected to the iRB1200 iBBU through a gigabit Ethernet (GigE) connection compliant with the Common Public Radio Interface (CPRI) standard. Connection to other compliant fronthaul devices can also be facilitated using the Ethernet fronthaul port. The iRU4438 iRRH interconnects with compliant radio antennas and the iRB1200 iBBU which operates within the RAN portion of the LTE wireless network.

Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Yours Sincerely Charlie Blackham Director

Additional User Manual Statement - EM Field exposure iRU4438 RF Exposure FCC Maximum Permissible Exposure (MPE) limits for equipment operating in the frequency range 1500 – 100,000 MHz is 1.0 mW/cm 2 . Following installation and commissioning, the safe distance from the antenna is the greater of: 20cm Or r cm, where r = √ (PG/4πS) P: power input to antenna(s) in mW G: numeric gain of antenna relative to isotropic radiator S: power density in mW/cm2 = 1 mW/cm2 The device has four antenna ports, so safe distance from the antenna shall be the greater of: 20 cm or √ (4*PG/4πS) Which gives 20 cm or √ (0.32*P*G) cm. The iRU4438 is designed to be used with one of three standard antennas combinations: • Four 2 dBi omni-directional antennas • Two 9 dBi 2-port cross-polarised directional panel antennas • Two 18 dBi 2-port cross-polarised directional panel antennas These give the following safe distances from the unit: Antenna gain Safe distance (cm) 2 dBi 22.4 9 dBi 50.2 18 dBi 141.4

In order for the Analyser to be able to accurately measure the EVM, it was locked to a reference signal from the Proxima unit. The transmit Frequency of Proxima is locked to GPS in typical install and 0.016 ppm was added to the EVM error as that represents the worst case baseband card frequency stability.
