LTE: The Next-Generation Network

Introduction.Long Term Evolution (LTE) is going to reshape the wireless industry. Not only will LTE expand the types of applications that can be used on wireless devices, but its implementation will open the networks to new and unique devices. LTE is the technology weve chosen for our fourth-generation (4G) wireless network. (The rst generation was analog; the second, digital; the third, and current, is broadband [EV-DO Rev. A].)

Of the major U. S. wireless carriers who have chosen a 4G network technology, Verizon Wireless, AT&T, and T-Mobile have opted for LTE, while Sprint has gone with World Interoperability for Microwave Access (WiMAX). LTE has a major advantage over WiMAX in that LTE is emerging as the global standard for wireless carriers worldwide.

Verizon Wireless will begin o ering LTE service in some 30 markets in 2010, while AT&T has announced it may begin o ering LTE in mid-2011. Verizon Wireless will continue to expand the LTE network over the next several years with the ultimate goal of covering its footprint by the end of 2013.

Why we chose LTE. Verizon Wireless chose LTE as its next-generation technology because LTE:

Will have the speed to run bandwidth-intensive applications. Is the global mobile communication standard chosen by a majority of the worlds leading carriers, which means opportunities for seamless roaming.Is interoperable with existing mainstream cellular technologies. Has low latency to support real-time applications (average 30 ms end-to-end round trip delay). Is highly secure.

A quick overview of LTEs technical speci cations and attributes.

LTE devices. While the initial devices expected for LTE are USB modems, Verizon Wireless has openly published its 700 Mhz C-Block LTE speci cations, and through its Open Development initiative, anticipates a variety of exciting, innovative LTE devices to be created for the LTE network.

LTE peak and average speeds. LTE promises peak speeds of up to 100 Mbps for download and up to 50 Mbps for upload. While actual network loads will impact performance, average user throughput speeds are expected to be 5 Mbps to 12 Mbps for download and 2 Mbps to 5 Mbps for upload, comparable to landline broadband speeds. Under this scenario, you could download an albums worth of MP3 les or an entire audio book in about a minute at average throughput speeds.

The evolution of the Verizon Wireless network.

LTE and SIM. LTE will operate in a SIM environment. A Subscriber Identity Module card (SIM) is a small integrated circuit in the form of a smart card. Its where key subscriber information, such as your mobile phone number, contact lists, call history, etc., is stored within a device. Its also where key carrier information is stored, including system ID, preferred roaming lists, and more.

SIM cards are highly secure, with sophisticated authentication schemes built into the chip. They also contain memory, so you can store applications and data, making them extremely exible and customizable. And SIM cards can be moved from device to deviceby the user.

That means that with LTE, youll be able to use a Verizon Wireless SIM card in any compatible device, and run that device on our network. For example, youll be able to transfer the SIM card from your smartphone into an LTE-compatible camera, to directly upload your photos onto the Web. This opens up the Verizon Wireless network to a whole new generation of nontraditional wireless devices.

And, as Tony Lewis, vice president of Open Development at Verizon Wireless, points out, hardware is just the starting point. Verizon Wireless is encouraging developers to get excited about designing innovative products and services the future requires. In broadly sharing how LTE standards for access and transport will translate into our speci cations today, we can provide a framework for all developers who want to begin their work immediately.

Conclusion.LTE will change the wireless industry as we know it.

LTEs high speeds and low latency mean that youll be able to run virtually any application designed for wired use on a mobile device. High-de nition video. Real-time video conferencing. Video telephony. Voice over IP (VoIP).Multi-player gaming. Mobile TV. Bandwidth constraints that have kept many applications tied to landlines will be history.

LTE will also provide unprecedented global coverage and inherent global mobility. And because were deploying LTE in the 700 MHz band, with its propagation characteristics and spectrum depth, well have strong in-building penetration.

Plus, because of the open approach were taking with LTE development, youll be able to access the Internet from any compatible device. And were expecting to see a ood of new devices, from netbooks to mobile Internet devices to other home electronics like cameras that havent traditionally been online. Theres no telling what might be created to run on the Verizon Wireless network.
