Growing Your Microwave Capacity

Making Sense of the Options to Determine What’s Best for You

Microwave technology is evolving rapidly to meet the ever increasing demands for data throughput.

The recent data explosion has created a burden on communications networks to provide the necessary capacities to support the network and its applications. Networks that were initially deployed to carry low capacity voice circuits are now faced with the challenges of being increasingly adaptive, elastic and intelligent to accommodate the constantly evolving traffic it carries.

My Takeaways from IEEE 5G World Forum Panel Discussion on vRAN and 5G Transport

by Gary Croke

On July 10th, I participated in a panel at IEEE 5G World Forum with colleagues from Vodafone, Bell Labs/Nokia, Facebook and Collinear.

FORUM: 5G vRAN Over Less than Ideal Backhaul

Through a lively discussion and exchange of ideas we explored backhaul/fronthaul considerations in a virtualized RAN in 5G network. We discussed CRAN, vRAN and their benefits, challenges and issues. Continue reading

Why Aviat Created IRU 600 v4: High Capacity and High Gain

IRU 600 v4 was announced 2 months ago and is the newest all indoor radio for the North American market. The latest version offers the ability to utilize true wide channels (up to 80MHz) and high modulations (up to 4096QAM) to transport ultra-high capacities, while retaining the radio’s extra high-power (EHP) amplifier. The IRU 600 v4 builds on the tradition of its industry-leading predecessor, which introduced the EHP and reshaped the way microwave paths were designed; users were finally able to design longer links with higher path reliability while using smaller antennas. Now with the v4, users can also design paths with approximately 3x more capacity than the previous version. Continue reading

Evolution of Transport for 5G

4G Transport Options Today

Ethernet Based Backhaul

4G transport options are tied to base station functionality and operator’s deployment scenarios. Traditional base stations are decentralized and have relatively low capacity and latency requirements. Although there are many scenarios were traditional base stations are desirable, operators are looking at ways to reduce costs and optimize performance. As the RAN is evolving to become greener and more profitable in many cases Ethernet alone does not meet RAN evolution. Continue reading

A Key to More Cost-effective Backhaul and Fronthaul Networks – The Case for vRAN

Virtualized Radio Access Network (vRAN) Background

Fronthaul using CPRI evolved from the need of mobile operators to reduce their carbon footprint, obtain gains by pooling processing resources, and deploy advanced network features like Carrier Aggregation (CA) and Coordinated Multipoint (CoMP). The disadvantage of this type of Fronthaul is that it needs ‘Ideal Transport’ (Defined by 3GPP as 2.5 µs latency and throughput up to 10 Gbps). Continue reading

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. Continue reading

Microwave Path Design – From Slide Rules to Cloud-based Artificial Intelligence

Aviat has released a new free path design app in AviatCloud (if you have not seen it, register here to get access). By simplifying and automating the path planning process and delivering it free in the cloud (new updates are immediately available without needing new software downloads), this new tool is a huge step forward in microwave path planning. In an effort to understand how far we’ve come and where we’re headed, we’ve put together a short blog on the evolution of microwave path planning tools. Continue reading
