MULTI-GIGABIT SUBSCRIBER EXPERIENCE
The GigaSpire Mesh BLAST
®
u4m is a high performance wireless satellite that delivers the
latest 802.11ax Wi-Fi technology in a consumer friendly form factor. Subscribers want their
Wi-Fi to work with any device in any location throughout their home. Over time, the
numbers, types and locations of these devices has exploded. In response to the rapid
adoption of Wi-Fi IoT devices – like door locks, IP cameras and thermostats – CSPs must
now provide ubiquitous Wi-Fi coverage. In addition, the demand for video content continues
to grow and subscribers expect to watch anywhere on any device. The Calix GigaSpire Mesh
BLAST u4m enhances coverage and capacity with the latest 802.11ax Wi-Fi radios,
transmitting at the maximum allowable regulatory limits. For homes that need additional
coverage and capacity, the Calix Mesh-Enhanced Carrier Class Wi-Fi solution has three
components: A GigaSpire, GigaSpire Mesh satellites, and the Calix Cloud. The GigaMesh
satellites are optimized for interoperability with GigaSpires 5.0 GHz 802.11ax radio., thus
allowing for the delivery of throughput rates of over 1.2 Gbps. Along with the 2x2 2.4 GHz
radio, the GigaMesh provides over 1.8 Gbps of total service bandwidth.
In addition to support for high-speed Internet (HSI) services, CSPs need solutions that allow
them to support a full complement of additional services, including IPTV and guest Wi-Fi.
In response, the Calix solution supports differentiated quality of service (QoS) as well as
isolation between the services. To ensure a seamless mobile streaming experience, the
software used by the GigaSpire and GigaMesh has been enhanced to support both band
steering and network-assisted node steering. Steering directs subscriber Wi-Fi devices to
connect to the radio signal that results in the best user experience.
Calix leverages the latest standards for roaming and steering, including 802.11k, 802.11r and
802.11v. The combination of GigaSpire and GigaMesh satellites enables subscribers to
receive Gigabit broadband data, IP video, and voice over (VoIP). Using the latest 802.11ax 5
GHz technology – incorporating 2x2 multi-user multiple-input and multiple-output (MU-
MIMO) with beamforming – the BLAST u4m satellite allows CSPs to extend the access
network inside the home and establish a strategic location for the delivery and control of
broadband services.
Calix engineered the BLAST u4m for optimal whole-home coverage with simultaneous dual-
band 2.4 GHz and 5 GHz operation and dynamic beamforming at 5 GHz. For maximum
performance, the BLAST u4m supports high-power 2x2 MIMO spatial diversity at 2.4 GHz
and 2x2 MU-MIMO at 5 GHz. The BLAST u4 and BLAST u4m solution easily delivers high
definition (HD) and Ultra HD (UHD) video and data throughout a subscriber’s home.
The Calix solution is scalable, allowing CSPs to initially deploy a GigaSpire and then add
GigaMesh satellites to the end subscriber’s home network as the need arises for additional
coverage. One of the strengths of the Calix solution is that CSPs can leverage the
instrumentation provided by the GigaSpires and GigaMesh satellites to identify when the end
subscriber can benefit from an additional GigaMesh. This allows them to be proactive and
upsell additional services and assets.
