Comcast Takes WiFi Serious


Image take from

Last week Comcast announced at The Cable show its plans to expand its WiFi coverage to over 8 million hot spots throughout the U.S.  These hot spots will be deployed in 19 of the 30 largest cities in the U.S.  Comcast will focus on three target locations: public areas, businesses, and residential areas. 

According to the announcement, the vast majority of hotspot deployments will be residential.  Today’s Xfinity platform uses MoCA to distribute video and data throughout the home.  MoCA is the network backbone for the Xfinity platform and adding public hotspots should be as simple as adding a WECA to the network.  WECA or wireless Ethernet coax adapters are commercially available products using MoCA as the backbone to the WiFi network.  These devices can be developed as WiFi routers or WiFi extenders used to improve WiFi coverage in the home.  Announced extender solutions from Actiontec or Netgear could easily do the job.    

A few weeks ago, the MSO announced its 1 millionth hotspot deployment.  So how popular is WiFi coverage.  Well, through Comcast’s Xfinity WiFi network alone, an estimated 200 million WiFi sessions were established and the need continues to grow.  By 2018, Cisco estimates that 88% of all mobile/portable data traffic will be over WiFi.  To get more details on the article from Lightreading, click here.

Report: Wi-Fi 30 percent slower than wired

Report: Wi-Fi 30 percent slower than wired | Wireless – CNET News.

Anyone who’s ever used a wired connection at work versus their corporate WiFi shouldn’t be surprised that wired is faster.  What is surprising is how much slower WiFi makes your broadband- 30% in the US according to this comprehensive study which polled 14,000 users across 4 countries over 4 months.  Specifically, US download speeds averaged 7.4Mbps over a wired connection compared to 5.2Mbps for a WiFi download.  The significant difference was also seen in the UK (26.5% slower for WiFi), Italy (40%), and Spain (30.1%).  Download the Epitiro study whitepaper here.

This should be an alarm for both consumers and their ISPs.  If you’re paying $50/month for 10Mbps cable modem service, you’re really only getting 7Mbps on your WiFi devices.  Those “wasted” 3Mpbs are leaking out of your home network in the form of retransmissions, lost bits, and general waste.  Your ISP should be as concerned as your power company to conserve, even more so since they are getting paid a flat rate.

Moral: Save Bandwidth, Get a Wired Network!  And since most homeowners don’t want to rip up their walls, installing a MoCA coax network is the next best thing to wired Ethernet (and less expensive).

3 Antennas vs 1 Coax: WiFi Still Can’t Do What MoCA Does

Three Stream N For HD Streaming: Close, But No Cigar

As the late great Howard Cosell said “I’m just telling it like it is”, and so are the guys at SmallNetBuilder as they once again stage their HD Smackdown using the latest WiFi competitor, 3 stream 11N.  Identified by 3 antennas instead of the usual 2, the latest in WiFi technology has demonstrated increased throughput, but can it successfully stream 1080P HD video without interruptions?  Sadly, it’s more “Agony of Defeat” as summed up by SmallNetBuilder:

It may seem hard to believe, but all the additional bandwidth provided by three-stream N still isn’t enough to ensure trouble-free 1080p wireless streaming. The best performance I could achieve still had minor, occasional problems during fact action sequences with a strong, next-room signal and the router set to spectrum-hogging Auto 20/40 MHz bandwidth mode.

So how do you hook up to your brand new Internet TV?  Not with the (2 antenna) dongle that comes with the TV and it doesn’t look like powerline does the job either.  What do the reviewers recommend?

So it still appears that your best bet for trouble-free 1080p network play remains 100 Mbps Ethernet, with MoCA a viable alternative if your setup allows it.

Brand New Blu-ray Players, Same Old WiFi Problems

Toshiba has came out with two new Blu-ray players, the BDX2500 (WiFi ready) and BDX2700 (WiFi-enabled), and they are also coming out with the new 3D model BDX3000 later this year. The players are equipped to stream videos from Netflix, CinemaNow, and VUDU.  However, the reviewer found a glaring weakness with WiFi:

My network and the player could not connect reliably over a 50-foot to 60-foot stretch even in a one-story apartment. Then I moved the player into the same room as the wireless router—an instant fix. Netflix and Pandora streamed sans glitches… be sure you place the player within range of your network, or your entire experience with the BDX2700 will be marred by glitchy performance and, ultimately, frustration.

WiFi can be unreliable for audio/video streaming for a number of reasons:  solid walls and floors, interference from other routers, or too many WiFi devices in the area.  Most people aren’t going to be able to use their Blu-ray players in the same room as their wireless routers so they’ll need another way to connect.  MoCA is filling that need for a solid wired connection from the TV to the router and supporting your Blu-ray, Internet TV, Game Console, and more.

Why-Fi? LG Electronics BD390 Blu-ray Disc Player –

LG Electronics BD390 Blu-ray Disc Player –

LG BD390

This PC World reviewer raves about the top of the line LG Blu-ray player stating:

The images it delivered to an HDTV were among the best we’ve ever seen. And with support for BD-Live, CinemaNow, DLNA, Netflix On Demand, Wi-Fi, and YouTube, the BD390 provides top-flight networking capabilities.

However, just the only thing he finds lacking is the built-in Wifi networking:

Speaking of poor video quality, the BD390 is one of two Blu-ray players we’ve seen with built-in Wi-Fi (the other is the Sony BDP-S560). This is a convenience for viewing BD-Live and YouTube content, but unless you have an exceptionally strong signal, we would advise against using Wi-Fi for CinemaNow or Netflix. When we tried it, we noticed a serious drop in image quality.

If that’s not screaming for a wired home network connection, either Ethernet or MoCA, to the living room – expect to hear more.  Stay tuned for more news from CES on why MoCA is THE way to go for networking to the Home Theater.
