In
the lead-up to Mobile World Congress, 5G continues to receive a lot of hype and
media coverage, promised as the be-all/end-all for a customer’s connectivity
needs. What does this mean for the cable operator? As with many competitive
threats, there will be both challenges and opportunities with this new wireless
technology.
Before
we go into those challenges and opportunities, let’s review what 5G is
promising to bring to the wireless landscape (as outlined by Verizon’s “Eight
Currencies of 5G” keynote at CES):
Speed
with peak data rates of up to 20 Gbps on the downlink and 10 Gbps on the uplink
Throughput
with data volumes up to 10 terabits per second per square kilometer
Mobility
with devices staying connected while moving up to 500 kilometers per hour
1
million devices per square kilometer density
Energy
efficiency with significant reduction compared with 4G
Rapid
service deployment, both network and device
5
ms latency to network edge
999%
(five 9s) reliability

The
faster speeds, greater capacities, and lower latencies of 5G are attained
through dedicating additional frequency spectrum to 5G, and through greater
spectral efficiency. Spectral efficiency is a measure of how well a given
access technology can transmit bits over a limited frequency spectrum. The 5G
efficiency improvements are achieved by using advanced modulation techniques,
including sparse code multiple access (SCMA), polar codes, and filtered
orthogonal frequency-division multiplexing (OFDM), as well as utilizing massive
MIMO—each of which could command its own article for explanation.
These
greater performance capabilities are poised to support existing customer
services like high-resolution video and gaming, as well as emerging IoT
services such as remote healthcare, education manufacturing, and agriculture.
5G
has two distinct topologies: “traditional” cellular service and fixed wireless
access (FWA). 5G cellular will utilize the wireless carrier’s existing cell
tower infrastructure. FWA, as the name implies, is designed to provide fixed
broadband service to a home or business. FWA will bring the 5G small cells much
closer to the customer and will occupy millimeter wave (30 to 300 GHz)
frequencies. The challenge with providing reliable broadband service over FWA
is that the customer site needs to be line of sight to the small cell antenna,
and terrain, foliage and weather can impact link performance. This increased
cell density is an excellent backhaul opportunity for the cable operator.
Cable
operators may choose to offer 5G services directly. Operators of both cable and
wireless networks outside of the US, such as Rogers and Shaw in Canada, have
announced 5G trials. In the US, cable operators have more frequently opted to
partner with cellular carriers through a mobile virtual network operator (MVNO)
agreement. For these cases, 5G backhaul is a huge opportunity. In some markets,
more than 80% of the cellular backhaul is carried by the cable operator.
There
has been something of a kerfuffle recently over the definition of providing “5G
service” to a wireless customer. One wireless carrier recently started
broadcasting the 5G logo over the air to customers who were on the faster
portions of their network, a clear effort to begin promoting the new 5G
branding. Their rival wireless carrier maintained that they would only use the
5G logo when their customers are using new 5G devices and connecting to the
network over new 5G radio technology. Events such as these lead to 5G brand
confusion.
5G
will easily be the most talked about topic at this year’s Mobile World
Congress, and in the next couple of years, it will be offered globally by the
wireless carriers. Global 5G deployments are expected to start in late 2019 and
become the predominant coverage technology within three to 10 years.
So,
is 5G friend or foe to the cable operators? The cable industry has many options
to both compete with and leverage 5G technologies:
Offer
traditional cellular coverage, or establish an MVNO to do so
Offer
FWA coverage, or establish an MVNO to do so
Provide
backhaul connectivity to wireless network operators for both of the above
options
Continue
to expand their Wi-Fi networks in the home, business, and public hot spots,
especially in light of advanced 802.11ax technology (which will be the subject
of another article)
At
the end of the day, a network operator’s business objective is to offer
complete mobility to the customer, so that they can receive all of today’s and
future services while on the go. The customer really doesn’t care what wireless
technology their services traverse as long as they can access these services
quickly and reliably. By embracing 5G technology where appropriate, the cable
industry is poised to do just that.
