As residential users are looking for reliable and affordable ultrahigh-capacity broadband services, the huge demand for internet bandwidth poses both a challenge and an opportunity for communications service providers.<\/p>\n
On one hand, fibre rollout may not be feasible as trenching to install the cable could be costly and time consuming, while wireless broadband service can be rolled out much faster.<\/p>\n
On the other hand, if the network bandwidth provided cannot meet the demand, the customers are likely to switch to other operators.<\/p>\n
The service provider\u2019s objective is to deliver enough capacity to satisfy the needs of the customers, generate more revenue from each customer and attract even more customers.<\/p>\n
With the proper technology, they would be able to roll out additional network capacity much quicker than wireline-based operators, due to the inherent ease of deployment of wireless technology.<\/p>\n
The service provider needs to find cost-effective wireless broadband technology that:<\/p>\n
\u201cICASA has recently opened up the 60 GHz spectrum, also known as V-Band, for Point to Multipoint deployments.”<\/p>\n
“This allows us to use Cambium\u2019s cnWave platform to its full potential, true multi-gigabit Point to Multipoint networks are now a reality. Better still, this regulatory change allows us to deploy high-capacity mesh networks using Cambium\u2019s cnWave 60 GHz technology.”<\/p>\n
“Multi-gigabit mesh networks are a true game changer for numerous verticals, not just traditional ISPs. Public Wi-Fi will no longer be limited by backhaul capacity, and modern surveillance systems can be operated seamlessly, without bandwidth constraints, to name just a few possibilities,\u201d says Teresa Huysamen, Wireless Business Unit Executive at Duxbury Networking, local distributors of Cambium Networks technology.<\/p>\n
PON (Passive Optical Network) fibre networks are fast, delivering an aggregate 2.5 Gbps broadband, but they become extremely expensive in urban zones as cost of access and labour increases.<\/p>\n
Fixed wireless broadband offers a fast and predictable installation routine and low per node cost. Fast deployment equates to rapid access to revenue.<\/p>\n
But what about performance?<\/p>\n
New technology in fixed wireless broadband is now delivering 7.6 Gbps of aggregate network throughput and packet latency measured in microseconds, not milliseconds.<\/p>\n
Cambium Networks\u2019 60 GHz cnWave solution is engineered to deliver higher value at lower cost than a pure PON fibre network.<\/p>\n
cnWave is 802.11ay based and Terragraph certified. With mesh support, cnWave forms a distributed multi-gigabit backhaul layer to end points.<\/p>\n
Powered by cnMaestro, a single pane of network management can be used for both the cnWave mesh network and any other Cambium equipment, such as Wi-Fi hotspots.<\/p>\n
Fixed wireless broadband using 60 GHz enables any service provider, integrator or municipality, large or small, to design, deploy and manage very high-speed public and private networks or community Wi-Fi networks.<\/p>\n
When 60 GHz fixed wireless is used to extend the reach of the fibre network, cost for the last few hundred metres is dramatically reduced while delivering multi-gigabit speed and low latency.<\/p>\n
When deploying public Wi-Fi, a Wi-Fi AP at the network edge provides the capacity and common radios needed to support public and community Wi-Fi networks that connect any smartphone, tablet or laptop.<\/p>\n
Each Wi-Fi hotspot will need two components: a Wi-Fi AP for public access and a broadband 60 GHz client node.<\/p>\n
These two components can be interconnected with data and power to simplify the deployment. For example, Cambium Networks\u2019 cnWave V1000 (Mid-Gain Client Node) can be powered by a Cambium Wi-Fi 6 XV2-2T0 or XV2-2T1 outdoor Wi-Fi AP.<\/p>\n
Conversely, any Cambium Networks Wi-Fi AP can be powered by cnWave V5000 (Distribution Node) or V3000 (high-gain Client Node).<\/p>\n
Each V5000 DN has two sectors and can provide an aggregate L2 capacity of 7.5 Gbps. If channel bonding is used, each V5000 DN can provide 15 Gbps throughput.<\/p>\n
Key features include:<\/p>\n
One big challenge for deploying a 60 GHz wireless network is that it has very short range and requires clear line of sight (LOS) which makes it very challenging to provide cost-effective wireless coverage.<\/p>\n
With meshing technology, a 60 GHz network from Cambium Networks can mitigate the non-line-of-sight (NLOS) problem by converting NLOS connections into multiple short LOS hops.<\/p>\n
Thus, it makes a cost-effective solution possible by significantly reducing the point of presence (PoP) sites where backhaul is provided.<\/p>\n
Unlike Wi-Fi-based meshing, a 60 GHz solution does not lose capacity when traffic traverses through multiple hops.<\/p>\n
This is because with Wi-Fi meshing, all nodes in the mesh network will be able to communicate with each other given the RF characteristic.<\/p>\n
Also, Wi-Fi standards mandate \u2018listen before talk\u2019 protocol, meaning that Wi-Fi allows only one signal to transmit at a time.<\/p>\n
This results in very high noise floor and, even worse, many times only one node in the meshing network would be able to transmit at a time.<\/p>\n
In a 60 GHz meshing network, the signal degrades so quickly within a short distance that it allows multiple nodes in the mesh network to transmit\/receive at the same time.<\/p>\n
As the operators add new users, they can easily extend coverage by adding new DNs.<\/p>\n
The total network capacity is completely determined by the total backhaul capacity. As the network grows, the operator can introduce additional PoP sites to increase total network capacity.<\/p>\n
In conclusion, the explosive residential demand in ultrahigh broadband internet capacity brings both challenges and opportunities to the wireless internet service provider.<\/p>\n
Cambium Networks\u2019 60 GHz technology provides a cost-effective solution that is well positioned to help communications service providers to mitigate the technical and business challenges while consistently satisfying end customers.<\/p>\n
