Altai A8-E: Características e Benefícios do Dispositivo de Acesso Wifi Superior, Notas de estudo de Eletrônica

O altai a8-e é a estação de acesso wifi exterior idealizada para maximizar a cobertura em ambientes urbanos densos, com benefícios como tecnologia de antena inteligente, plataforma multirádio, planejamento de cobertura especializado para rede wifi em escala de cidade e controle de interferência adaptativo. Oferece cobertura superior em ambientes nlos (sem linha de sight), alta taxa de transferência de dados e baixa latência, tornando-se uma opção ideal para rede wifi em locais singulares, áreas de campus e cobertura em escala de cidade.

As an integral part of our Super WiFi
network infrastructure, key benefits of
the Altai A8-E include:
Extended coverage in a Non-Line-of-
Sight (NLOS) environment which
matches the foot print of most
micro-cellular deployments in dense
urban environments
Multi-beam Smart Antenna
Technology to provide superior signal
strength and link budget in dense
urban environment deployments
Multi-radio platform to maximize both
uplink/downlink performance
Cellular architectural radio and
coverage planning specially designed
for city-wide WiFi deployments
Adaptive interference control to
mitigate the surrounding interference
effects
Supports real-time applications such
as VoIP, video-streaming and
interactive gaming with minimal
latency
Standard 802.11b/g access and
802.11a wireless backhaul
Fast Ethernet or integrated 802.11a
wireless backhaul
Flexible antenna deployment
including rooftop, wall, tower and
lamppost mounting
Remote configuration through the
Altai Wireless Management System
(AWMS)
The Altai A8-E Super WiFi Base Station is the world’s leading WiFi
outdoor access point optimized for maximum coverage from a
minimum number of installation sites. The Altai A8-E has been
designed to provide industry best coverage and capacity
without complicated networking protocols or the need for a
high density of transmitters.
The A8-E is a multi-radio base station utilizing smart antenna
technologies and a patented signal processing algorithm to
provide the industry’s best coverage per base station, especially
in non-line-of sight (NLOS) environments. The multi-beam
antenna array of the A8-E is designed to provide up to 5 times
the range and 25 times per site coverage as traditional access
point. Accordingly, by using up to 96% fewer installation sites
than other WiFi systems to cover the same area, the A8-E
enables less complex network design and provides lower
latency for improvement in handling real-time applications such
as VoIP and video streaming.
Whether deployed for a single location, a campus area or
city-wide network coverage, the Altai A8-E is designed to
minimize the total cost of ownership with significant savings in
network equipment, broadband access, planning, site
acquisition and installation.
The Altai A8-E can also serve as last mile infrastructure for a wide
range of broadband applications. It provides low deployment
cost and fast provisioning of WiFi systems with the greatest
coverage and bandwidth per installed base station.
The A8-E Super WiFi Base Station can also be deployed in
conjunction with existing micro-cellular wireless networks to
provide high bandwidth, high-speed fixed and mobile data
services.
