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.Read More

On July 10th, I participated in a panel at IEEE 5G World Forum with colleagues from Vodafone, Bell Labs/Nokia, Facebook and Collinear.
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.Read More
The arrival of 5G services will bring significant change to the way we consume bandwidth. Already, even well before 5G is rolled out, video comprises over one half of all network traffic and is predicted to exceed two thirds of all bandwidth by 2020.Read More
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.Read More
Long-Haul Trunking is a subset of the broader microwave market focused on solutions optimized for high capacity, long distance transmission operating in lower (less than 13 GHz) frequency bands, as an alternative to fiber. Traditionally, this segment has been composed of products in two categories, All-Indoor Trunking or Split-Mount Trunking.Read More
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.Read More
Public Safety networks are changing and becoming more advanced in terms of applications and services that are required by its users. 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.Read More
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).Read More
In 2017, Northern California Power Agency (NCPA) was faced with the challenge of linking two microwave sites in mountainous terrain with no line of sight between them. They were looking for an effective, cost-efficient way to complete the microwave segment of their network in California’s Northern Central area.Read More
Virtualized RAN (vRAN) enables operators to run Base Band Unit (BBU) functions on off the shelf hardware as virtualized network functions (VNFs). This can provide operators with the ability to avoid proprietary vendor lock-in as generic core and base station hardware can replace proprietary hardware. Currently Centralized RAN (C-RAN) uses a fixed Fronthaul split that requires a high capacity and low latency proprietary optical CPRI interface.Read More
