STATEMENT THAT HZB-S58-GX1 MUST BE PROFESSIONALLY INSTALLED AND 

SO IS EXEMPT FROM THE ANTENNA RESTRICTIONS OF FCC PART 15.203, 

INCLUDING INFORMATION ON ANTENNAS USED FOR TESTING 

 
This letter is submitted with regards to professional installation of the HZB-S58-GX1 radios 
and the antennas used for testing. The HZB-S58-GX1 radios must be professionally installed 
and so is exempt from the antenna restrictions of FCC Part 15.203. The HZB-S58-GX1 is a 
group of products manufactured by Proxim Corporation in Sunnyvale, California. 
 
The HZB-S58-GX1 is to be certified for operation under Part 15.247 and 15.407 of the FCC 
Rules in the 5.25-5.35 GHz, 5.725-5.825 GHz and 5.725-5.850 GHz bands. The equipment is 
designed for point-to-point communications and will carry data signals using T1/E1/DS3 or 
Ethernet interfaces. Due to the unique requirements of installation and integration of these 
systems, typical consumers or businesses will not have the proper training required for successful 
implementation of these systems. 
 
The HZB-S58-GX1 is not designed for use by the general public, and will be sold as follows: 

• 

Through the Proxim sales force to professional communications users  

• 

Through designated and professionally trained Proxim Value Added Resellers to business 
users under individual reseller agreements. 

 
These companies will either use their professional telecommunications engineering staff to carry 
out the installation or will subcontract to professional installation firms. On occasion, a 
professional installation firm will purchase the HZB-S58-GX1 radios directly. 
 
The HZB-S58-G1X radio will be used for fixed, permanent or temporary, outdoor links 
requiring the use of directional antennas at 5 GHz band, which tend to be mounted on towers. 
These antennas will have narrow beam-widths and require professional installers to align them. 
 
In addition, the HZB-S58-GX1 radio must be set up for the specific line interface required 
during installation. This procedure must be carried out by a qualified professional installer for the 
equipment to operate properly.  
 
The output power of the HZB-S58-GX1 radio will be adjusted to meet any applicable EIRP 
limits by the professional installer during installation. The method of adjusting the output power 
is described in the manual written for use by professional trained installers. 
 
The HZB-S58-GX1 radio is a full-duplex device with a common transmit/receive port. The 
addition of an external amplifier to boost the transmit power would disable the receive signal, 
thus rendering the HZB-S58-GX1 radio inoperable. In addition, high power amplifiers (not 
generally available at 5.2-5.8 GHz) cannot be used without ensuring that signal saturation does 
not occur (because this would produce unrecoverable deterioration of the receive signal). Thus, a 
non-professional installer could not accomplish the addition of an amplifier.
