| As
of now, ABS can provide pan-city coverage (more than 90 percent) across commercial
areas in Chennai and has already enabled wireless connectivity for SME and Enterprise
clients through WiMAX based on 802.16d standards at a speed range of 2 to 10 Mbps.
This would help the end user to stay connected to the Internet and Intranet with
high uptime. These WiMAX deployments use NLOS wherein the customer premises equipment
(CPE) does not have to face the base station (BTS). The forthcoming 802.16e standard
will be even capable of mobile Internet, states an official release. ABS
has also deployed WiMAX Networks beyond Chennai with limited coverage in many
other prominent Indian cities such as Coimbatore, Hyderabad, Bangalore, Pune,
Delhi, Cochin and Ahmedabad and would extend its pan-city coverage in a phased
manner. Apart from these, ABS also plans to WiMAX another 26 cities in the near
future, the release adds. With
WiMAX, end users can have Internet accessibility based on portable technologies
at an affordable price. WiMAX is unaffected by environmental or climatic disturbances
and provides relief to organizations from 'last mile' connectivity concerns both
in urban and rural areas with limited network infrastructure. The
backend systems and processes (OSS / BSS) of ABS are highly sophisticated with
end-to-end manageability from Sales Prospecting to Order Management and Internet
Protocol (IP) Provisioning. All these systems are developed in-house and have
the capability to accommodate future business requirements of ABS, the release
adds. ABS
is also identifying and deploying Wi-Fi 'hotspots' throughout the Chennai city
with indoor and outdoor points backhauled with WiMAX. Internet services at these
'hotspots' will be enabled through pre-paid cards integrated with Payment Gateways
for on-line registration and subsequently activated using the 'Authentication,
Authorization & Accounting' (AAA) mechanism. |
