MVS Comunicaciones will use Aperto Networks to deliver broadband wireless access with guaranteed Quality of Service to Mexico City, Guadalajara and Monterrey this year and will market these services to six additional cities by the end of 2004.
MVS, a leading radio/television programming and carrier services company in Mexico and Latin America, holds MMDS (2.5 - 2.686 GHz) licenses capable of addressing 95% of Mexico’s businesses. Aperto’s PacketWave will deliver business-grade high speed wireless access in the three largest urban areas of Mexico and beyond.
“Mexico City is the second-largest metro area in the world, but with 20 million inhabitants and thousands of demanding businesses in just 1,800 square kilometers and heavy vegetation throughout the urban area, it has the highest density of population and greatest environmental challenges of any wireless market in the world,” declared Ernesto Vargas, President of MVS Television.
“After rigorous tests with multiple suppliers and platforms, we selected Aperto’s powerful PacketWave systems due to their proven superiority in the areas we consider critical to our markets -guaranteed QoS for high-speed business services.
Aperto’s base stations and subscriber units enable both licensed and unlicensed frequency broadband wireless access for business-grade users. Providers use PacketWave systems to deliver wireless E1 and Fractional E1 speeds, wireless VPNs and VLANs, disaster recovery and Hot Spot backhaul, as well as VoIP and streaming media. Through 2004, MVS will deploy broadband wireless access via Aperto Networks systems to Puebla, Veracruz, Mexicali, Tijuana, Le n and Toluca, in addition to the above-mentioned cities.
Aperto Networks has been a pioneer in establishing the 802.16a standard and is committed to delivering systems for WiMAX certification.
Aperto’s Medium Access Control (MAC) is based on an advanced form of Time Division Multiple Access (TDMA). TDMA is superior to other MAC technologies such as Polling and CSMA/CA, which are used by some of the other vendors in this space. Even among TDMA technologies, there are wide variations, and one such variation called DOCSIS is widely used in the Cable Modem space. However DOCSIS is not the most appropriate protocol for Broadband Wireless Access.
Aperto’s implementation is closest to the TDMA technology that was recently ratified by the IEEE 802.16a Working Group.
