Here’s a very brief summary of some of the major mobile milestones that many of us have experienced over the last 15 years, in five-year increments. What did we miss or would you add to these timelines? We’ve also provided a quick snapshot of our projections for the next five years. Let us know what you think…
Pre-2000: The wireless wilderness shows early signs of development
In 1973, the first mobile phone call was placed with the words “guess where I’m calling from?”, the motto of the early days of cellular voice. Mobile phones became commercially available in 1979, but the early phones were expensive and heavy, with large nickel cadmium batteries weighing them down. In the 1990s, lithium ion batteries were introduced, reducing the weight and size of the phones by more than half, and the phones began to be offered at more affordable prices. Also in the early 1990s, 2G phones deploying GSM technology were introduced, marking the shift from analog to digital communications. With GSM, limited data services such as text messaging and paging began to be available. The GPRS standard was introduced in the late 1990s, delivering packet-switched data capabilities to existing GSM networks and allowing users to send graphics-rich data as packets.
2000 – 2005: “Call me”

From the first batters up to the plate in South Korea in 2012, with a flurry from Metro PCS in the U.S., Voice over LTE (VoLTE) seemed to be in a field of dreams and not making much noise or progress. However, bring it on baby… as VoLTE may be getting ready for prime time in 2014. Analyst firm Infonetics expects 30 commercial networks and 51 million subscribers with VoLTE by the end of this year and that number will grow to the major leagues on 2015.
So, what is it? And why is it good? Read More »

Last mile connectivity remains a challenge in developing countries. Businesses need a smart last mile solution that is also secure, reliable, provides investment protection and at the same time, keeps costs low. Serial connections still offer a low cost connectivity option for businesses that generate basic network traffic minus video or voice. Cellular wireless technologies offer a reliable and cost effective way of connecting people and places where wired connectivity is not available. It is growing into a widely used connectivity option especially for small site connectivity such as ATMs, Retail, Gas Stations and the like. However, cellular wireless is often assumed to be a complicated means of providing connectivity due to ever evolving technology and diverse Service Provider configurations. What if your business could connect to the world through any Service Provider in your region from the same network device?

If you’ve been a long time user of Wi-Fi, at some point you have either observed someone encounter (or have personally suffered from) so called “sticky client syndrome”. In this circumstance, a client device tenaciously, doggedly, persistently, and stubbornly stays connected to an AP that it connected to earlier even though the client has physically moved closer to another AP.
Surprisingly, the reason for this is not entirely…errr…ummm…unreasonable. After all, if you are at home, you don’t want to be accidentally connecting to your neighbor’s AP just because the Wi-Fi device you’re using happens to be closer to your neighbor’s AP than to your own.
However, this behavior is completely unacceptable in an enterprise or public Wi-Fi environment where multiple APs are used in support of a wireless LAN and where portability, nomadicity, or mobility is the norm. In this case, the client should typically be regularly attempting to seek the best possible Wi-Fi connection.
Some may argue that regularly scanning for a better Wi-Fi connection unnecessarily consumes battery life for the client device and will interrupt ongoing connectivity. Therefore the “cure is worse than the disease”. But this is true only if the client is very aggressively scanning and actually creates the complete opposite of being “sticky”.
The fundamental issue with “stickiness” is that many client devices simply wait too long to initiate scanning and therefore seeking a better connection. These devices simply insist on maintaining an existing Wi-Fi connection even though that connection may be virtually unusable for anything but the most basic functionality. Read More »

We’ve been really busy but also very thrilled about the work we’re doing to future-proofing the network, and it seems we’re not alone. One of our latest innovations, adaptive radio modules for the AP3600, has been selected by UBM as a Best of Interop finalist for the Wireless award category!
It’s an honor to be recognized for our innovation and technological advancements in wireless, and we wanted to share a bit more about our submission with you.
What are the Adaptive Radio Modules?
The Adaptive Radio Modules a family of solutions in a modular form factor that allows customers to adapt their wireless network to their current and future needs. The Adaptive Radio Modules provide a dedicated third radio that can be field upgraded on the 3600 Access Point.
Cisco offers three adaptive radio modules for the 3600 Access Point:
