a previous blog post, High
in Fiber, Low in Network Saturates, I discussed how coverage and capacity
requirements in both wired and wireless
networks are extending the reach of fiber optic solutions.
I was reminded that while fiber is often the transmission medium of choice for backhaul networks, it is not always
readily available or economically viable. This is particularly true where mobile network cell sites are
positioned primarily to maximize subscriber coverage. In these cases, deploying
new fiber to a network control station or switching center is often impractical
and leasing an existing line imposes a significant recurring operating expense.
Microwave radio links provide an ideal alternative solution, which can be
rapidly deployed, allowing operators to cost-effectively bridge the gap without
provide a reliable, high-capacity solution for many backhaul scenarios such as
a bridge from access points to a fiber point-of-presence, transporting to and
from network control stations and switches or aggregation centers. The cost-efficiency
alone often makes it the logical choice.
much of the talk is about fiber optic systems and fiber-to-the-antenna,
there is little doubt that microwaves are a viable alternative to fiber for
mobile network backhaul. Microwave systems are well positioned to meet the
projected growth demands of the foreseeable future.
enhancements in radio functionality provide the platform for competitive,
reliable high data rate transmission, significant complementary technological
strides in the associated antenna systems have also been made to maximize the
value proposition of microwave backhaul.
this in mind, the CommScope
Infrastructure Academy developed a course, SP6105
Microwave Radio Antenna Link Fundamentals, to offer a great
introduction to microwave infrastructure technology and deployment. It has certainly
helped me understand these other important options in the world of
infrastructure choice. Hopefully it can help you as well.
would like to hear your feedback. Have you deployed fiber to meet your capacity
requirements? Are you using microwave radio links for backhaul? Please let us
know in the comment section below.
