FreeMile testing tube
Testing in office/lab should be done with help of special testing tube available from SAF Tehnika
Attaching SAF FreeMile to the antenna / 1
Circular flange – position of SAF FreeMile determines polarization
Lockers for easy SAF FreeMile attachment to the antenna
Washers should be taken out
Attaching SAF FreeMile to the antenna / 2
• Directly slip-fitted to the antenna• SAF FreeMile radios should be installed in opposite polarizations according to polarization indication on the label and Web GUI
Spectrum analyser in Web GUI
• Precise - resolution 1 MHz;• Allows checking presence of interference;• Helps to choose which channel to use.
SAF FreeMile built-in protection
• Protection of power supply and interfaces (Ethernet & E1/T1)
• 2-level protection on Short Voltage jumps
• Protection of power supply on over voltage >58V DC, but external power supply must be equipped with fuse
• Protection of power supply on mixing + and – poles
SAF FreeMile built-in management
• Web based GUI via integrated Web server• Telnet server, accessible using command interface• SNMP management via integrated SNMP agent• No special software for link configuration is needed• Any Web browser - Internet Explorer, Firefox, Opera, Safari• Terminal access via ‘Hyper terminal’ or Telnet
FreeMile 17 distances
FreeMile 24 distances
SAF FreeMile 17/24 target customers
• ISP / WISP• Corporate networks• Private customers• All 2.4 and 5.8GHz spectrum users
Solution for ISP network
Solution for corporate wireless network
SAF FreeMile Highlights
• Full duplex capacity 100Mbps + 2E1/T1• Low interference comparing to links in 2.4GHz and 5.8GHz• Hitless modulation switching (ACM) feature ensures high
availability even at bad weather conditions• Easy configuration from Web interface and up-to-date
network management over SNMP protocol• Radio polarization sensor for easier installations• RF Spectrum analyzer
FreeMile 17/24GHz (FDD) vs. 5.8GHz (TDD ) / 1
• Higher throughput: in Full-duplex FDD radio capacity is simultaneously transferred in both directions while TDD radio provides only one-way or simplex throughput.
FreeMile 17/24GHz (FDD) vs. 5.8GHz (TDD ) / 2
Interference at 5.8GHz band may reduce link capacity up to
90%
• Minimal interference possibility17GHz & 24GHz frequency bands are not “polluted” comparing to 5.8GHz
FreeMile 17/24GHz (FDD) vs. 5.8GHz (TDD ) / 3
• Less radio signal propagation (less overshoot); • Possibility to reuse frequency:
– High performance antennas, high F/B ratio, narrow beamwidth – Automatic Transmit Power Control, ACM
• Narrow antenna beamwidth allows installing more links than with TDD systems
• Many wide beamwidth antennas in 5GHz cause interference
FreeMile 17/24GHz (FDD) vs. 5.8GHz (TDD ) / 4
Low latency• FreeMile 17/24 - 0.2 ms MAXIMUM vs. 5.8GHz - 2 ms MINIMUM• Latency variation: FDD - 0.1 ... 0.2ms vs. TDD - 2.0 ... 30ms
Benefit - with FDD systems: faster response time from the server, stable traffic throughput which is important for video & voice traffic (CCTV, VoIP, Skype)
FreeMile 24GHz5.8GHz TDD system
Real example from client, improved latency results by replacing 5.8GHz link by SAF radio link:
FreeMile 17/24GHz (FDD) vs. 5.8GHz (TDD ) / 5
• Carrier-class equipment: higher component quality with built-in surge arrester, grounding, EMC protection, wider temperature range, resulting in higher reliability of the link and lower RMA percentage;
• More Ethernet features: built-in managed Layer 2 switch enables the user to configure VLAN, QoS, STP, etc.
