Case Study: Can Extra High Power reduce need for Space Diversity?
Q: Can Extra High Power (EHP) Radios Reduce Need for Space Diversity (SD) in Microwave Networks?
A: Yes.
- EHP radios can reduce need for SD in some microwave networks by providing an optimum level of system gain, which will reduce fading—the problem SD was intended to mitigate
- Non-reflective paths will benefit the most from EHP
- Benefits include decreased numbers of antennas and lower capex
- For example, in a recent project using EHP radios, Aviat reduced the number of required antennas by 9.27 percent and capex by 5 percent

Multiband Microwave: It’s Not Just for 80GHz Links – Applications in Traditional Microwave Bands
Multiband backhaul links consist of running multiple channels at different frequency bands on a single link to improve capacity and reliability. Currently there are several products in the market (or in development) that are using a combination of E-band and microwave frequencies. An alternative is to take advantage of the larger channels of higher frequency bands (ex: 32 GHz) and better RF performance of lower frequency bands (Ex: 11 GHz) within the traditional microwave range.

Avoid Extra Expense: Use Extra High Power Radios Under Tower Standard TIA-222
TIA 222 standard provides tower designers with the design criteria and analysis procedures to design telecommunication tower structures. Rev-H is the latest version in a standard with a long evolution. The TIA-222 tower standard is critical to the safety and maximum equipment loads that structures can support. Rev-H was finalized late in 2017 and will take effect in most jurisdictions within the next two years.

A Realistic Look at Link Distances of 70-80 GHz Links
There has been significant growth in backhaul products operating in millimeter frequency range recently. Being subject to rain attenuation, and because different environments can have different characteristic attenuations, careful and precise calculation of theoretical distances is critical.

Multi-Band (70/80GHz + 6-23GHz) Backhaul
An analysis of viability of multi-band links: where/when/why…?
Multi-band backhaul links consist of running multiple channels at different frequency bands (typically 70/80G + 6-23G) on a single link to improve capacity and reliability. These links essentially operate like an extended ACM solution – giving more reliability than E-band and more capacity than the lower frequency channel operating independently.

Plan Your Microwave Network From the Cloud: Free Path Design Software from Aviat
Aviat has been rolling out free microwave path engineering software to customers and partners in varying forms since 1986. You may have been familiar with Starlink software – which estimated multipath performance and rain availability for line-of-sight 5-38GHz digital microwave radio hops and was designed specifically for initial path estimates.

Multi-Gigabit Microwave Networks
Options and Strategies for Maximizing Your Network Potential
In recent years the microwave industry has made great progress in capacity evolution – actually we’ve seen somewhere in the neighborhood of 30 times increase in microwave capacity over the past 10 years. In doing so, microwave has proven itself to meet the capacity of LTE and LTE-A applications and with some new evolutions to enable multi-gigabit links, is now well positioned for 5G as well.

State-Wide Microwave Network Case Study: Extra High Power Radios
This large western US state had a longtime relationship with a microwave radio vendor and would have continued buying from them if their radios and support evolved with the State’s needs. However, over time its needs changed and it had to have more capabilities from its communications network. But it did not want to unnecessarily build new sites and erect costly new towers.

Three Elements to IP/MPLS Success in the Microwave Access
In microwave communications—as in all electronic communications mediums—operators trend toward the latest technologies (e.g., IP/MPLS). They all have conditioning to think that newer is better. And by and large that’s right.
However, when it comes to IP/MPLS—one of the most advanced packet technologies—you need to handle this concept with care. Especially in a mixed infrastructure that includes microwave, fiber and other potential backhaul transport.
