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

Top 10 Pains of Operating Networks

Today’s networks are becoming more complex and difficult to manage. With reductions in budgets and skilled resources, many network operators are looking to outsource their operations to vendors with advanced network operations capabilities. Maintaining non-core functions, such as network operation centers (NOCs), is often not the best use of operator resources – and detracts from a focus on their core business – their customers. Continue reading

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. Continue reading
