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

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.
