1) Wireless LAN Client Devices

I wanted to go over some of this as we have come a long way in technology in this area in a short period. I remember with my first computer not having a NIC card and having to install a NIC card manually to be able to even connect to the internet. I also remember years later buying a lap top and assuming it was already inside the Lap top since it said Wireless Technology capable or something of that nature. Only to find out yes the lap top was capable and even had the spot for where it would be attached to the side but you had to buy it separate. Once again had to buy the NIC card separate and install it into the lap top. One thing I had not got with my laptop was the USB 802.11 radio NIC. Is this a portable NIC card that you can use the USB drive if you do not have the capability of installing one into your lap top? Is this what you use to make your laptop a hot spot? I cannot think of the name or see that in this area when you use the USB so your laptop can get internet from anywhere just as in your phone? (Mini PCI, Mini PCI express)??

We are now up to having wearable computers which are items like smart watches, wristbands, exercise sensors, and glasses. UK-based Juniper Research projects that the number of wearable devices shipped will rise from about 13 million in 2013 to 130 million in 2018 and that the size of the market will jump from $1.4 billion in 2013 to $19 billion in 2018 (Coleman 2014).

2) I hope I never see external wireless radios again. Years ago all company laptops (at my old job) where purchased without internal wireless radios. These external wifi card would get lost or broken; a big hassle. Conversely, the wireless diagnostic tool in the Mac OS is very helpful. This chapter also touches on network monitoring via NMS solutions. An example here at my work would be Fortigate appliances. Lastly, often times at work I would hear about a VPN concentrator. The chapter defines this role as such: “Layer 3 and 7 VPN Concentrators Some WLAN controller vendors also offer VPN server capabilities within the controller. The controller can act as a VPN concentrator or endpoint for PPTP, IPsec, or SSL VPN tunnels”.

3) PC cards are utilized to give a laptop access to the WLAN. Many individuals now utilize external USB devices to gain access. These cards are used to add proprietary ports on a notebook. This includes SD cards, compact flash card, and micro drive CF. The card bus was onventedvin 1995 and is present in laptops post 1997. The card bus supports bus mastering and allows the controller to talk to other devices and memory without accessing Computer. You can visual note the difference between card bus cards and older cards because the card bus cards will have a small gold strip present. Card bus Interface speed Depends on transfer type. In 32 bit word mode it is 66 in byte mode 33 and 132 in Sword or double word. What does this mean speed is relevant when it comes to accessabilty. SD cards are still in high use today when dealing with cellular service and doing well.

4) Stadium Networks

Technology-savvy fans are driving sport, concert, and event stadiums and arenas to expand the services that they are providing. Fans expect and demand a complete multimedia experience when attending events, including access to replays and real-time statistics. Through apps or websites, in-seat food and beverage ordering and delivery enhances the experience by allowing the fan to enjoy the action instead of standing in line for refreshments. Through texting and social media, fans expect to be able to share their sporting or concert experience with friends or interact with other attendees.

A well-designed stadium network can allow the venue to target sections or groups of people with directed advertisements, special offers, or customized services. Offers or services for fans in the bleacher seats would likely be different than those targeting the fans in the skyboxes. In addition to providing wireless services to the fans, it is important to remember that the stadium is a business and needs to support its own infrastructure and services at an event. A wireless network is needed to provide event operations with services such as reliable high-speed Internet access in the press box, ticketing and point-of-sale transaction processing, and video surveillance.

This section touches on the hospitality portion of larger wifi networks to provide fast and reliable services to patrons. My current work environment, while not a stadium, offers similar hospitality-based services. In the hotel industry that are vlans and servers dedicated to the mini-bar system and phone systems. Similarly, there is guest wireless available for all patrons (separate from the business network of course). The wifi is throttled since they share the same provider WAN. Additionally, Sonos wifi speakers are featured in some of the rooms. This created additionally overhead for our network admin.

5) I was just thinking about my configuration at home as well. I broadcast 2.4 and 5ghz networks with many devices in the house.

-iPhone

-Google Nexus phone

-iPad

-two laptops

-2 chromecasts

Unfortunately, the chromecasts are older models that cannot operate at 5ghz. I try to free up bandwidth on the 2.4 ghz network my using the 5ghz network with the laptops and smartphones. I haven’t found much to alter on the modem/router combo device from my provider that would improve my connectivity other than placing it in a central area. My buddy, who has his CCNA and CCNP, urges me to purchase my own equipment. Honestly, I don’t think I care enough at this point to invest in that. It’s good enough for now.

6) In chapter it discusses client utility and that there are three types. The three types are intergrated operating system client utility, vendor specific, and third party. The intergrated client utility im familiar with because it is used on every device like windows pc or iphone. The vendor specific utility is decreasing according to the book but there is still makret for enterprise grade vendor specific utility which has more configuration options. Third party utilities also allow custom configuration but the book says it also cost more money and are on the decline. Client utilities act as a interface of the NIC and end user.)

Thanks!
