    What Would It Take? (Downlink Edition)

    • 0 Comments
    If I were to ask you how fast you can go on LTE, you’d probably say 300 Mbps. That’s the number most often quoted as the peak downlink data rate for LTE. (Well, technically it’s 299.552 Mbps, but let’s not quibble over a few kbps...

    Bearer Building and Tunnel Timing

    • 0 Comments
    By now, you should be familiar with the concept of an EPS bearer, which transports user traffic between the User Equipment (UE) and the PDN Gateway (P-GW) in LTE networks. If you’ve taken just about any Award Solutions course on LTE, you’ve...

    Codewords and Layers and Ports, Oh My!

    • 0 Comments
    We throw a lot of terms around when we discuss LTE data transmissions, especially when we get into some of the details of sending data over the PDSCH using multiple antenna techniques. We describe transport blocks as holding the data we're trying...

    Which is Better?

    • 0 Comments
    Everybody knows that 4G is better than 3G. Otherwise, why would the industry be spending all that money and time and effort to create and deploy a brand-new wireless technology, if the old one was just as good? That would be crazy, right? Let's compare...

    1xEV-DO vs. LTE: Channel Quality Reporting

    • 0 Comments
    Although the details obviously differ, all 3G and 4G mobile wireless data solutions share a common goal: drive data as fast as it can go, but no faster. In other words, these systems are designed to take into account the current RF conditions: the...

    1xEV-DO vs. LTE: Bearers

    • 0 Comments
    Every wireless network carries two types of information between the mobile device and the various nodes in the network: control signaling and user traffic. In 1xEV-DO and LTE networks, the high level views of the signaling and user bearers are remarkably...

    1xEV-DO vs. LTE: Registration

    • 0 Comments
    When a mobile first shows up in a network (and occasionally after that), it must go through some form of registration process. Registration tells the network that a new user has arrived, and allows the network to authenticate, configure and track the...

    1xEV-DO vs. LTE: Connection Setup

    • 0 Comments
    So far in this ongoing series comparing 1xEV-DO with LTE, I've covered initial system acquisition and the random access process. Although the specific details obviously differ, 1xEV-DO and LTE have some remarkable similarities in these functions...

    1xEV-DO vs. LTE: Random Access

    • 0 Comments
    In my previous blog, I compared how 1xEV-DO and LTE devices perform an initial system acquisition. Now I'll continue with the next step in setting up a data call, random access. In virtually every mobile wireless system, mobiles attempting to...

    1xEV-DO vs. LTE: System Acquisition

    • 0 Comments
    LTE (Long Term Evolution) has been designed from the very beginning to provide a natural evolution path for GSM/GPRS and UMTS networks. As a consequence, someone knowledgeable about UMTS will find many aspects of LTE to be familiar. But how does someone...

    LTE and 1x/1xEV-DO Terminology and Concepts

    • 0 Comments
    By Don Hanley, Senior Consultant - 2/2009 1xEV-DO and LTE networks are surprisingly similar in many respects, but the terms, labels and acronyms they use are very different. How can a 1xEV-DO operator make sense of this new jargon? Introduction...
