I recently read the rather interesting announcement from NTT DoCoMo where they demonstrated LTE running over the unlicensed 5GHz band. They report a 60% increase in spectral efficiency over IEEE 802.11n Wi-Fi. The article also noticed that LTE-U is now referred to as Licensed-Assisted Access using LTE or LAA-LTE. This caused me to pause, and think about several things.
The comparison between LAA-LTE and Wi-Fi is not (and should not be) about spectral efficiency. Rather it is about several other factors:
- A robust network with a diverse client ecosystem (does anybody reading this blog own an IP device without Wi-Fi? How many of those devices contain LTE? How many are Wi-Fi only, without any SIM card?)
- The ability to support neutral host deployments (are stadium owners willing to deploy LAA-LTE if it only supports one operator?)
- The ability to co-exist in a multi-operator environment (how would LAA-LTE operate in dense environments when it has to co-exist with LAA-LTE APs from other operators?)
- The ability to co-exist in a multi-technology environment (would if it adversely affects the existing and extensive deployments of Wi-Fi infrastructure?)
- A number of Mobile operators have agreements with Wi-Fi providers for offloading cellular traffic (how does one enable such a scenario with LAA-LTE?)
And if you really want to talk about speeds and feeds, it’s interesting that the test was done against 802.11n, when 802.11ac is now widely available, providing speeds that exceed LTE-Advanced speeds of 1 Gbps (IEEE 802.11 ac Wave 1 provides maximum speed of 1.3 Gbps and Wave 2 provides maximum speed of 3.5 Gbps). It’s also important to note that LAA-LTE has not been defined yet and so it’s very likely that the LAA-LTE implementation tested here does not have the politeness mechanisms required in certain regulatory domains like Europe. These mechanisms allow fair usage of the unlicensed spectrum by allowing other users an opportunity to transmit and share the spectrum. These mechanisms already integrated into Wi-Fi will add additional overhead to LAA-LTE that will reduce its spectral efficiency, a factor that needs to be taken into account in any comparison.

Think about what is going on in the APJC Mobile Market for a minute:
- In Korea, mobile data traffic on 2G, 3G, and 4G networks increased approximately 70% between 3Q 2012 and 3Q 2013.
- In China, mobile data traffic of China’s top 3 mobile operators grew 90% in 2012 and 72% from mid-2012 to mid-2013.
- In Japan, mobile data traffic grew 92% in 2012 and 66% from 3Q 2012 to 3Q 2013, according to Japan’s Ministry of Internal Affairs and Communications
- While in India, Bharti Airtel reported mobile data traffic growth of 112% between 3Q 2012 and 3Q 2013 and Reliance Communications reported mobile data traffic growth of 116% between 3Q 2012 and 3Q 2013.

In this continuing series about Mobile Services Monetization, let’s look at so-called Multi-Device Data Plans. Spurred by the adoption of the Apple iPad and Android tablets, many operators have introduced mobile data plans that encourage users to connect these devices to 3G and LTE networks, rather then relying solely on Wi-Fi. These Multi-Device Data plans offer subscribers the ability to have a single contract that allows use of more than one device against a single monthly data usage quota. This provides users convenience, value, and incentives to buy cellular-enabled tablets and other “secondary devices”. Further, these Multi-Device Data Plan have driven higher data use and pushed users to increase to higher-tiered data quotas, according to some operators.
Trying to stand out among U.S. operators, T-Mobile recently announced that for a fee of $10/month, it will allow subscribers to add a tablet to an existing smartphone subscription *and* get a tablet data quota equal to the quota they have signed up for with their smartphone. So for only $10, this Read More »

Moving Public Safety Forward: Invest in the Future, Not the Past.
Use Existing Radio System and Smartphones, with an Etherstack and Cisco Solution
If you’ve got an analog radio system, upgrading to P25 just got much easier and much less expensive.
Some agencies have received an end-of-life and end-of-support notice from their radio network manufacturer. If you’re in this position, there’s a better option for entering the FirstNet era than upgrading your entire radio infrastructure. The problem with jumping to another proprietary radio network is that it might lock you into another 20-year single-vendor solution.
Now there’s an effective and cost efficient way to modernize your existing network radio network infrastructure—whether or not it’s P25, and even if it’s reached end of life. Here are three steps.

How Internet of Things Is Transforming Public Safety
Use Case 1: BYOD for Police Officers
The Internet of Things refers to connecting currently unconnected people and things, and it’s transforming public safety. This blog explains how police officers can securely use commercial smartphones and tablets in the field. Future blogs will describe other ways to use the Internet of Things to improve communications, collaboration, and operations.
Police officers are clamoring to use their iPhones, iPads, and Android devices for work. For law-enforcement agencies, allowing bring-your-own-device (BYOD) is appealing because it can save money, and mobile apps for law enforcement improve situational awareness.
Until now, two things have stopped police departments from allowing BYOD. One is governance. To use smartphones and tablets for incident response, departments need a way to enforce standard operating procedures. Lacking this, the NYPD recently had to remind officers to use radios instead of smartphones for official communications. Here’s the article in the New York Post.
