60 GHz cnWave Network Elements

60 GHz cnWave utilizes a hierarchy of different physical and logical elements to create a network topology. These network elements consists of nodes, sectors, sites, and links, and are described in further detail below.

Node

A node is a general purpose compute unit that controls one or more sectors. V1000 and V3000 nodes support a single sector, while V5000 nodes support up to two sectors.

There are two different types of nodes:

DN - Distributes bandwidth to neighbouring cnWave nodes. A DN is considered a fiber PoP when the SFP+ port/10G Ethernet copper port is utilized to connect the cnWave network into a provider’s IP network.

CN - Terminates IP connectivity to a customer (similar to a modem) and wirelessly connects to a DN.

Additionally, V5000, V3000 hardware consists of two types of DNs:

Primary-DN - Every site must have one Primary-DN. The Primary-DN supports both an SFP+ port and a 10G Ethernet copper port Ethernet port.

Secondary-DN - Creates additional wireless mesh links at a site. Up to three Secondary-DNs can connect to a Primary-DN.

Sector

A sector is a wireless baseband card attached to a node.

On V5000, each DN sector supports a total of fifteen wireless connections, comprised of up to two other DNs and up to fifteen CNs. Since V5000 has two sectors, its supports a total of 30 wireless connections to up to 4 x DNs and 30 x CNs

On V3000, each DN sector supports a single wireless connection because of narrow antenna coverage.

Each CN sector can only wirelessly connect to a single DN sector.

Site

A site is a logical element referring to the physical location at which one or more nodes are installed. A site is considered a fiber PoP when the Primary-DN at the site is interconnected to a provider’s IP network.

Link

A link is the logical element that defines the relationship between two sectors or nodes. There are two different types of links:

Wired - Ethernet links used for Primary-DN to Secondary-DN connections, or occasionally wired cross-site connections.

Wireless - RF links, used for DN to DN or DN to CN connections.
