5. Choosing the right radio style
All Outdoor Radio – radio unit will have an integrated antenna, or connectors. Typically mounted close to antenna or dish and fed by fiber or Ethernet cable and PoE powered. Easy to install, typically lowers overall installation cost. Most radios are IP based and have limited TDM capabilities.
Split Mount Radio – Two main components, indoor unit (IDU) and an outdoor unit (ODU). Two components are connected by using 3/8” coax cable. IDU is typically rack mounts and the ODU can either connect directly to the dish or be remote mounted and connected to dish using coax or flextwist jumpers. IP and TDM capabilities increase, higher installation cost overall compared to the all outdoor solution.
All Indoor Radio – All radio components on the ground. Large coax or elliptical waveguide is ran to dish. Most expensive solution to install. However, in the event of a radio outage, no tower climbing is involved. Most public safety networks are all indoor based.

6. Half Duplex/Full Duplex
Half-Duplex provides communication in both directions, but only one direction at a time. Most unlicensed radios are half-duplex. So if the radio is listed at 200Mbps, 100Mbps is TX, 100Mbps is RX.
Full-duplex allows communication in both directions simultaneously. Licensed radios are full-duplex.

7. Time Division Multiplexing
TDM is a method of putting multiple data streams in a single signal by separating the signal into many segments, each having a very short duration. Example of TDM is T1 or T3 service. When TDM ports are used on a microwave radio, bandwidth will be subtracted from the IP bandwidth of the radio.
DS0 – 64Kbps (typical voice circuit, 24 DS0’s equal a T1 circuit)
T1 (DS1) = Mbps (28 T1’s equal a T3)
T3 (DS3) = 45 Mbps (3 T3’s equal an OC3)
OC3 (STS3) = Mbps (4 OC3’s equal an OC12)
OC12 = Mbps
TDM traffic does not tolerate a high noise floor, understand your RF environment before deploying.

8. Ethernet/IP
Ethernet is the most popular and considered the network topology standard for most computer and VoiP connections. Connections are made at 10/100Mbps or 1/10Gbps. Cable lengths limited to 325ft between active devices.
IP is a network layer protocol for addressing and routing packets of data between host on a TCP/IP network. IP is a connectionless protocol that provides best effort delivery.
Most important part when designing an Ethernet backhaul is understanding the customers bandwidth needs.
What is type of data is being sent across the network?
How many concurrent users?
What is the plan for future growth?

20. Frequency Planning
The objective of frequency planning is to assign frequencies to a network using as few frequencies as possible and in a manner such that the quality and availability of the radio link path is minimally affected by interference. The following aspects are the basic considerations involved in the assignment of radio frequencies

21. Chain Configuration w/ Frequency Planning
All sites reside on a single path. This is a very sensitive topology in which the first link malfunction can cause a complete network failure.

22. Star Configuration w/ Frequency Planning
Star Topologies use a separate link from a hub to each site. This is very simple, but inefficient for microwave systems, as it requires possible longer paths and LOS for each link. The star topology also makes for poor frequency reuse since all links originate at the same point. U U VP HP HP U L HP VP U U

23. Ring Configuration w/ Frequency Planning
The ring topology provides superior network availability, due to the rings inherent path diversity. In a ring topology, service failures occur when two or more links malfunction. U U L HP VP VP HP L VP U L VP

25. Understanding the Basics
Free Space Loss (FSL) – is the expected attenuation of a signal as it travels away from a transmitting device. As the path distance increase, the power density decreases.
Fade Margin – the difference between the unfaded receive signal level and the receiver sensitivity threshold. Every link must have sufficient Fade Margin to protect against path fading that weakens the radio signal.
Link Availability – Fade margin is directly related to link availability, which is the percentage of time that the link is functional. The percentage of time that the link is available increases as the fade margin increases. Bottom line, design your link as far away from the radio’s receiver threshold as possible.
Path Fading – path fading occurs more frequently in flat, humid environments than in rough, dry locations. Therefore, a link in a flat humid area requires a greater fade margin to achieve the same level of link availability as a link in a rocky and dry location.

26. Understanding Your Rain Region

The energy of microwave signals is absorbed by rain: rain can cause an outage if enough energy is absorbed so that the receiver loses the signal

Climate Factor
Climate Conditions and Path Fading
Path fading occurs more frequently in flat, humid environments than in rough, dry locations. Therefore, a link in flat and humid areas requires a greater Fade Margin to achieve the same level of link availability as a link in a rocky and dry location. When calculating link performance the climate factor must be taken in consideration

30. Line-of-Sight LOS (clear Fresnel Zone)
Near LOS (60% of Fresnel Zone clear)
Non-LOS (majority of Fresnel Zone blocked)

31. Propagation Loses

34. Importance of a Site Survey
What is your customers budget?
What throughput does customer need?
Do you have line-of-sight for your path?
How are you mounting radios or dishes?
What is your cable path from radio to network head end?
Look for good grounding sources.
Don’t forget lightning protection.

35. Importance of Spectrum Analysis
Spectrum analysis is a must for unlicensed spectrum (900MHz, 2.4, 5.3, 5.4, 5.8GHz).
Spectrum analysis should be considered for 4.9GHz and 3.65GHz spectrum.
Spectrum analysis should be performed at height of antennas and dishes.
Document the noise floor and look for open channels.
Never assume that just because it’s rural that there is no noise floor, if towers are in the area, there is noise.
Consider making an investment or renting a good spectrum analyzer

36. Rules to Remember
As frequency rises, available bandwidth typically rises, but distance and ability to overcome obstacles is reduced.
The more sensitive the radio, the lower the power signal it can successfully receive, stretching right down to the noise floor. As radio modulation increases, receiver sensitivity decreases.
Know your noise floor, do a spectrum scan, survey your area to see what else is hanging in the air.
Establish a fade margin of no less than 10dB in good weather conditions, this will provide a high degree of assurance that the system will continue to perform effectively in a variety of weather or interference.
Avoid obstructions in your path whenever possible and understand the distance between you link.
Avoid force fitting a solution, hoping it will work.
Never go “cheap” on your cable
Understand your application and choose accordingly
