Indian telecom giant Tata Communications has launched a pair of global Ethernet services for multinational enterprises to create wide area networks (WANs) across India and onward to major business centers in North America as well as Asia, Europe and Africa.
The two services, Dedicated Point-to-Multipoint Ethernet and Dedicated Multipoint Ethernet, can be used by enterprises to create a "virtual business campus, with users around the world communicating as if they were in adjacent offices. Both of the offerings have passed Metro Ethernet Forum (MEF) certification tests - the 'Good Housekeeping' seals of the Carrier Ethernet industry. Indeed Tata boasts of being "the first global and Indian provider to earn MEF certification for its Ethernet services."
Dedicated Point-to-Multipoint Ethernet uses a hub and spoke network model to transmit data between a central location, such as a corporate headquarters or data processing center, and satellite locations. The Dedicated Multipoint service allows enterprises to deploy any-to-any network topology to create a global Ethernet WAN. Both new services have MAC address forwarding, completely private networks for each customer, and customer-premise to customer-premise service level agreements (SLAs).
"These two new services further deepen TATA's WAN Ethernet Service set, provide additional value to their customers and provide high quality services with features not found elsewhere in the market.
Tata's Ethernet network reaches eight cities in the U.S. from coast to coast, as well as two in Canada and a dozen in other countries. In its home country of India it has Ethernet points of presence (POPs) in 120 locations.
QUALCOMM tests 20 Mb/s speed using HSPA+
As per telecomweb news Qualcomm has completed what is characterized as the "world's first data call" using High-Speed Packet Access Plus (HSPA+) network technology, achieving a data transfer rate of more than 20 Mb/s in a 5 MHz channel.
The Qualcomm results were nearly twice as fast as the highest previously-reported HSPA+ results, in which Nokia-Siemens Networks demonstrated 10.1 Mb/s downlink performance. Both tests are highly significant in the positioning of HSPA+ as the interim generation between the current HSPA wireless broadband, typically delivering between 1 Mb/s and 2 Mb/s, and the eventual adoption of the much faster Long Term Evolution (LTE), with a theoretical 173 Mb/s bandwidth.
HSPA+, seen by many analysts as the technology which will destroy the market chances of IEEE 802.16e-2005 (which is being called by Intel and its camp followers mobile WiMAX), has a theoretical limit of 42 Mb/s in its current version, although most observers think it will top out at around 28.8 Mb/s. An advanced version that may double those specs is in the works. That, many feel, will be more than enough for HSPA/HSPA+ to be the dominant wireless broadband technology for the cellular industry until at least 2015
HSPA+, by the way, is also known s Evolved HSPA, HSPA Evolution, and I-HSPA or Internet HSPA. wireless broadband standard defined in 3GPP release 7.HSPA+, or whatever one calls it, is 3rd Generation Partnership Program (3GPP) Release 7. HSPA was Release 6, and LTE is Release 8.
