  • Backhaul is now the central battleground for LTE network migration, after years where backhaul was never an issue.But even now backhaul is not meeting the demand of 3G/HSPA in parts of the USA and Europe, so that users are now being seriously affected by bottlenecks in the backhaul network.Even now at this advanced stage, LTE backhaul requirements are still not well understood by operators. Three quarters of respondents to a Heavy Reading survey believed either that LTE backhaul requirements are not well understood or that whatever people believe now may change significantly over the next couple of years. Operators are divided over the expected capacity needs for typical LTE sites, and over what transport technology is best deployed in the access/low RAN and metro aggregation/high RAN – whether Carrier Ethernet (L2/VPN) or L3 IP/MPLS.
  • According to Infonetics (July 2009) total installed cell sites grew 10% from 2007 to 2008, from 2.0M to 2.2M, and will grow to 3.1M by 2013, a 2008-2013 CAGR of 7%. They also predict that microwave will dominate the mobile backhaul market, overshadowing nearly all other technologysolutions. Two thirds of mobile operators expect that microwave will account for more than 25% of their last mile backhaul to the cell site three years from now. 42% of operators believe that microwave will account for more than 50% of their last mile backhaul to the cell site in that timeframe. Heavy Reading Backhaul Survey 2009It offers mobile operators smooth migration from TDMto Ethernetbackhaul, as well as:• T1/E1 lines do not scale for bandwidth needs, and are not cost-efficient, even in NA where they are much cheaper• Fiber is not available or cost-effective to deploy for the majority of cell sites – can cost > $1million per mile.• The capacities can be 'turned up' as the mobile operator needs it• A single product can support voice on TDM, data on Ethernet• Microwave is the most appropriate solution for remote/rural base stations• Microwave is likely to also be widely used for microcell/picocell deployment• Microwave is usually quicker to deploy than landline
  • There is no “one-size-fits-all” situation that leads to the conclusion that fiber will be the sole media used for cellular backhaul in North America.Although fiber may be the preferred media by many operators, many of the major US operators are buying an Ethernet transport service rather than owning their own backhaul. Mobile operators that lease backhaul capacity from local exchange carriers (LECs) or from alternative transport carriers do not view backhaul transport as a core competency. Ovum’s carrier interviews for this report showed no material shift from buy to build and thus the lease-line model is likely to continue — with the difference being Ethernet will be substituted for traditional T1.
  • Mobile backhaul networks must evolve to support the introduction of IP transport to support new broadband services, increase network capacity and flexibility and support lower overall operational costs.Optimizing the network to support hybrid TDM+IP helps maintain high quality TDM voice services – the bread and butter, while enabling network expansion and gradual migration path to the next generation 4G
  • MW is well placed to meet LTE backhaul network requirements. Cost as well as time to establish links is very competitive.
  • “In the middle of difficulty lies opportunity.” Albert Einstein3.5G HSPA+ and LTE require Ethernet backhaul to decouple network capacity increases from network cost increases

    Taking the ‘haul’ out of backhaul
  • The Mobile Internet Tsunami meets the Backhaul Bottleneck
    Backhaul is the central battleground for LTE network migration
    Even now backhaul is not meeting the demand of 3G/HSPA
    LTE backhaul requirements are still not well understood by operators*

  • Hybrid fiber/microwave backhaul
    Nearly 1 million new sites worldwide by 2013
    Fiber is the natural choice for LTE backhaul, but connects less than 20% of NA sites today
    Copper lines will not provide the capacity scalability needed
    Microwave is the natural choice for sites where fiber cannot reach economically

  • An Opportunity for Fiber Wholesalers
    • Majority of cellsite connections today using leased copper
    • These connections will migrate to leased Ethernet Private Lines over fiber
    • Both Verizon and AT&T are targeting 90% penetration in the next 2 to 5 years
    • Wholesalers and MSOs are ideally positioned for this opportunity
    • Microwave economics work for aerial fiber runs beyond 1 ¾ miles.
    • Microwave can play a key role, but wholesalers generally lack microwave expertise

  • Mobile Network Evolution, not Revolution
    Mobile backhaul networks must evolve
    Maintain essential high-quality TDM voice services
    Gradual migration path to all-IP for next generation 4G/LTE
    There’s no silver bullet or one size fits all

  • Global Microwave Market
    Microwave market worth $4-6 billion/yr
    >75% is mobile backhaul
    >1 million units/yr globally
    Nearly 50% of the world’s base stations are connected by microwave
    Global Cell Site Connectivity (2009)
    Microwave 48 %
    Copper 15 %
    Fibre 37 %

  • Packet Microwave Market Growth
    Packet (Ethernet/IP) microwave is the fastest growing market segment
    Packet microwave can also support TDM (Hybrid)
    New technologies enable much more efficient use of available spectrum

  • There’s no one size fits all in backhaul
    With the right backhaul technology, Operators can turn the growth in bandwidth demand into an opportunity for competitive advantage
    Fiber will not be the only answer to the next generation backhaul challenge
    Microwave combines smooth network migration with LTE-readiness, and is a perfect compliment to fiber.
