Memotec - Redefining Network Efficiency

Although initial deployment of HSPA service can be done on the existing transmission infrastructure with solutions such as Memotec’s 2G-3G RAN optimization, the expected growth in HSPA traffic and ramp-up in service speed –equivalent to several E1s – require new alternatives.

With Memotec’s CX series, MNOs can offload all or part of the HSPA traffic over less expensive IP-based broadband access services such as cable, xDSL, WiMAX, PON or Metro Ethernet. The result is a far more efficient use of network resources, enabling carriers to reduce OPEX and CAPEX while still deploying cutting-edge services.

Using lower cost per bit broadband access services such as ADSL2+ or VDSL, allows to offload HSPA traffic from the main transmission network. Mainstream 2G/3G revenue generating services integrity is preserved being kept on the existing RAN infrastructure. Eventually, broadband access services might carry all the cell site traffic migrating to an all-IP RAN.

The CX series receives the HSPA traffic at the Iub interface over ATM IMA E1 (using dedicated VCCs), or Ethernet. Offload is achieved in full-duplex or half-duplex mode (download path) over the alternate access path (Ethernet uplink or ADSL2+/VDSL modem). Real-time 2G and 3G voice & data services remain on the current existing transmission network. The current RAN can also be used as backup in case of broadband access service outage. Synchronization integrity is maintained through the existing RAN connectivity.

The deployment of 3G GSM involves providing every mobile customer with broadband data services at 256 kb/s and up. But most GSM mobile operators readily admit that universal deployment of 3G base station equipment ("Node Bs") is not a cost effective model. While deploying 3G "Node Bs" in urban and suburban areas makes sense, the cost of deploying a 3G radio access network (RAN) in rural and lower density areas is difficult to justify from both an economic and technical (over-capacity) point of view.

EDGE (Enhanced Data GSM Environment) has been touted as the economic solution for 3G services global coverage. As EDGE is fully compatible with 3G applications, a GSM operator can provide continuity of services when a mobile user roams from a 3G-serviced area to a 2.5G EDGE area, thus providing 3G services (even 4G VoIP) global coverage at a reasonable cost.

But deploying EDGE services require additional backhaul capacity, usually a minimum of 256 Kb/s per BTS, which comes at a significant additional cost. This is a significant issue if the operator is not certain that the additional revenue the new data services will be sufficient to cover the additional costs.

AbisXtender solves this problem. Thanks to AbisXtender's true network utilization behavior and statistical multiplexing capability between voice and data flows, a mobile operator can use AbisXtender to deploy EDGE data services essentially "for free", that is to say without increasing OPEX costs while still benefiting form the additional revenue.

AbisXtender delivers data services at speeds greater than 128 Kb/s using 2.5G EDGE technology over satellite links, providing the mobile customer with a near-broadband experience, and throughput that is equivalent or better than ISDN data services.

Since it is based on existing 2G BTS and technology, EDGE comes at a minimal hardware upgrade cost to existing 2G BTS equipment, and does not require changing the existing cell radio planning and design (unlike 3G deployment which requires smaller cells). Therefore, EDGE is the perfect complementary solution for deploying 3G services and applications in rural and lower density areas where high data traffic capacity is not required, and larger cell areas are a must.

Conclusion: By allowing mobile operators to deploy 2.5G services "risk-free' with a minimum additional OPEX, AbisXtender enables mobile service providers to offer global 3G services across their entire networks, including low density and rural areas which have usually no access to broadband services. AbisXtender is the solution that effectively bridges the "digital broadband divide".

With the increasing number of smartphones and 2.5G/3G/4G dongle users accessing the Internet, mobile networks are strained with huge levels of data traffic. A direct consequence is a progressively poor user experience and service quality with mobile web services. Operators must address this challenge immediately to avoid customer churn, but network capacity cannot be extended indefinitely!

Memotec xG is an award-winning solution that optimizes mobile web services. Based on TCP session optimization as well as intelligent compression and caching techniques, the xG reduces the bandwidth required to load a web page, to download pictures, and send emails or documents. The RAN and network resources are better utilized, ultimately providing better performance.

With its ultra-scalable architecture, the xG is a clientless solution that fi ts with every mobile device. Its unique features allow transparent deployments without any changes in the mobile core network. Highly reliable, the xG can enhance the mobile service immediately without any risk.
