Simplifying MPLS Transport Networks with Segment Routing

By Said Jilani, Sr. Customer Solutions Architect

MPLS is a mature technology that has been deployed by service providers and private networks for many years. In a time of building pressure for organizations to modernize transport infrastructure to support new applications, MPLS enhances the performance, reliability, and scalability of IP based networks. Successful implementation has demonstrated a reduction of costs associated with maintaining complex expensive legacy TDM based transport network, improved scalability, and higher efficiency.

Sub-Band Free Radios – Do they really help?

By Stuart Little, Director of International Product Line Marketing

In the past years, a few microwave vendors have introduced ‘sub-band free’ RF outdoor units into the market. The main claim of these radios is that a single hardware variant can be deployed in any frequency sub-band, simplifying and lower costs involved with ordering, deployment and sparing of microwave networks.

However, these new radios are not available in all bands and come with a number of limitations, including lower RF performance, larger size, and weight, higher cost, limitations in modulation and channel sizes, amongst others. Continue reading

Microwave Remains Operational through Field Fires in George, South Africa

The Garden Route district is located along a 300 kilometer stretch of the south-eastern coast of South Africa in Western Cape province, about 450 kilometers east of Cape Town. It’s a popular tourist destination, especially in spring and summer. However, its lush vegetation is prone to field fires, particularly in drier times.

In late October 2018, field fires raged across the area, with ongoing blazes in the municipality of George and the Outeniqua Pass area. Hundreds of municipality firefighters, area volunteers, and firefighters assisting from other districts fought to contain the fire. Seven fatalities were reported, and the pass was closed for an extended period. Entire suburban sections of George, not far from thickly wooded areas along the Garden Route, were evacuated.

Aviat’s Proof of Concept with Bouygues Telecom Promises Automation and OPEX Savings

The commissioning process for microwave—from integration to testing to equipment configuration to turn-up—can be lengthy and can involve multiple teams at multiple sites and get more complicated as microwave moves to include more sophisticated Layer 2 and Layer 3 capabilities. With added complexity, configuring intricate radio parameters in the field can increase labor-intensive operating procedures, increase operating costs, and unfavorably affect an operator’s return on investment and bottom line.

State of Colorado’s Lessons Learned from Spring Fire 2018

Unfortunately, throughout much of the western half of the USA, wildfires have become all too common. Moreover, with the recent fires in California this month, things seem to be getting worse. Wildfires and other natural disasters can have significant impacts to communications systems affecting not only personal cellular communications but also first responder and other mission-critical communications. Fire, police, emergency workers and other first responders need communications during natural disasters more than ever and this is precisely the time when thing just need to work. Continue reading

Space Diversity and Lowering TCO

By Stuart Little, Director of International Product Line Marketing, US

Space diversity has been an important feature in long haul microwave systems for many years to counteract the effects of multi-path fading. Space diversity enables very long links over highly reflective surfaces such as bodies of water for example, where a non-diversity link would not deliver the high availability required.

The Role of Microwave in Rural Broadband

According to NTCA–The Rural Broadband Association, broadband use has multiplied by more than twenty times since the early 2000s. However, three out of every ten Americans still do not enjoy its benefits. That represents a sizable market, and a good part of that market is in rural areas that lack the infrastructure for it. For service providers, the challenges lie in entering those markets quickly and effectively, and at lower ownership and operational costs than fiber or other solutions.

Wireless Backhaul is Not Dead Yet

By Stuart Little, Director of International Product Line Marketing, US

This Halloween, zombies aren’t the only thing coming to life. Evolutions in e-band and multi-band mean wireless will play a crucial role in the rollout of 5G.

5G is coming (and hopefully it won’t be accompanied by White Walkers) and will bring with it tremendous challenges for network operators, and no less critical will be backhaul, where needed capacities will grow from the hundreds of Megabits to multiple Gigabits. In their latest Microwave Outlook (from December 2017), Ericsson forecasts that by 2022 the typical backhaul requirement for a high-capacity radio site will be in the around 1 Gbps, increasing to as much as 5 Gbps towards 2025.

WISPAPALOOZA: After the Show

The annual WISPAPALOOZA conference has come to an end, and a key takeaway from the show is the growth potential for WISPs. What started as a small conference with only a few booths has now grown to 2000+ attendees and 600+ exhibitors.

As much as the show is improving and space for the WISP business is expanding, the sentiment from a few small companies was that they still struggled with procurement issues from vendors. They received the products they needed but the time that it took and the poor service they received was still a complicated process, and in some cases, non-existent.
