BLAST u4g Overview
The Calix GigaSpire BLAST u4g (GS2128G) is a new generation smart home system that
integrates GPON ONT and residential gateway functionality into a single system. It supports
GPON WAN, while providing the ultimate Wi-Fi experience. Besides supporting broadband
connectivity of data and video services, this intelligent, high-performance system offers the
latest 802.11ax ‘Wi-Fi 6’ technology. The GigaSpire BLAST u4g provides switching and
routing functions that support multi-Gigabit throughput for IPTV video and data services.
The GigaSpire BLAST u4g is a premium smart home integrated system that delivers the
latest Wi-Fi 6 certified technology (802.11ax). The GigaSpire BLAST u4g integrates a GPON
ONT to provide carrier-class WAN. On the LAN side, Wi-Fi and two (2) Gigabit Ethernet
interfaces are available for customer multi-media devices. The GigaSpire BLAST u4g enables
residential subscribers to receive broadband data, Internet Protocol (IP) video, and voice
(POTS) services. Using the latest 802.11ax technology in both the 2.4 and 5 GHz radios, the
GigaSpire BLAST u4g incorporates 4x4 streams of Wi-Fi delivery (2x2 @ 2.4 GHz and 2x2
@ 5 GHz). In addition, with multi-user multiple-input and multiple-output (MU-MIMO) and
beamforming, the GigaSpire BLAST u4g allows service providers to extend the access
network inside the home and establish a strategic location for the delivery and control of
broadband services.
With Wi-Fi being the de facto wireless data communication technology of choice for
consumers, Calix engineered the GigaSpire BLAST u4g for optimal whole-home coverage
with simultaneous dual-band 2.4 GHz and 5 GHz operation and dynamic beamforming in
both spectrums. Leveraging the latest Wi-Fi 6 features, the GigaSpire BLAST u4g provides
longer range, higher efficiency, and less interference compared to earlier generations of Wi-Fi
technology. The GigaSpire BLAST u4g easily delivers HD and UHD (ultra-HD) video and
data throughout a subscriber’s home in an increasingly video-rich and mobile broadband
environment.
